Abstract and Figures

Fifteen species of Muricidae are listed from Papua New Guinea. Six new deep water species are described: Conchatalos samadiae spec. nov., Nipponotrophon barbarae spec. nov., Scabrotrophon manai spec. nov., Scabrotrophon maranii spec. nov., Scabrotrophon puillandrei spec. nov., Scabrotrophon maestratii spec. nov. Eight other species listed are new records. The genus Enixotrophon is used, based on geographical congruence and Pagodula obtusa Marshall & Houart, 2011, Pagodula procera Houart, 2001, and Trophon pulchellus Schepman, 1911, are transfered to it. The previously accepted synonymy of Trophon johannthielei Barnard, 1959, with T. pulchellus is questioned. The variability of Scabrotrophon inspiratus Houart, 2003 is redefined as well as its spiral cord morphology.

deep seamounts, (ii) Astrolabe Bay from 200 m to about 1000
m, (iii) the chemosynthetic environments of the deep sea,
including cold-seep environments and plant debris (Samadi
et al. 2015: https://tel.archives-ouvertes.fr/hal-01081793/doc-
ument). Further deep-sea work (MADEEP and KAVIENG
expeditions) was conducted in 2014, but the biological sam-
ples have only recently become available.
During the BIOPAPUA and PAPUA NIUGINI expeditions,
specimens of Muricidae were collected alive between 307 and
1019 m. Altogether, fteen species were collected during the
BIOPAPUA cruise and 11 during PAPUA NIUGINI, with an
overlap of 6 species sampled by both cruises, representing
nine new country records for Papua New Guinea and six spe-
cies new to science, which we have decided to name after the
people involved in the collecting, sorting, analysis and cura-
tion of the material. Unless otherwise indicated, all the mate-
rial studied is deposited in MNHN.
METHODS
The characters used here to describe the shell morphology
are the general aspect of the shell, its shape and size, colour,
shape of the spire and number of protoconch and teleoconch
whorls, features of the protoconch, shape of the teleoconch
whorls and features or form of the suture and of the subsutural
band, of axial and spiral sculpture, the aperture and siphonal
canal. When known, the characters of the operculum and
radula are also used. Unless otherwise mentioned, the species
descriptions are based on all the examined specimens or on a
representative selection of them, including the holotype and the
other specimens of the type material.
The morphology of the radula is described starting from the
rachidian tooth followed by the lateral teeth.
The method for determining diameter, height and counting
the number of protoconch whorls is explained in Textg. 2.
ABST RACT
Fifteen species of Muricidae are listed from Papua New
Guinea. Six new deep water species are described:
Conchatalos samadiae spec. nov., Nipponotrophon barbarae
spec. nov., Scabrotrophon manai spec. nov., Scabrotrophon
maranii spec. nov., Scabrotrophon puillandrei spec. nov.,
Scabrotrophon maestratii spec. nov. Eight other species listed
are new records. The genus Enixotrophon is used, based on
geographical congruence and Pagodula obtusa Marshall &
Houart, 2011, Pagodula procera Houart, 2001, and Trophon
pulchellus Schepman, 1911, are transfered to it. The previ-
ously accepted synonymy of Trophon johannthielei Barnard,
1959, with T. pulchellus is questioned. The variability of
Scabrotrophon inspiratus Houart, 2003 is redened as well as
its spiral cord morphology.
INTRODUCTION
Starting in the early 1980s, the Tropical Deep-Sea Benthos
programme explored many archipelagoes in the South Pacic
(Bouchet et al. 2008), but Papua New Guinea remained
untouched until 2010, when MNHN, IRD and the University
of Papua New Guinea joined forces to document this vast
and complex region. In 2010, the BIOPAPUA expedition
explored parts of the Bismarck Sea and of the Solomon Sea,
with emphasis on the fauna of seamounts and fauna associated
with wood falls (see Pante et al., 2012; see also http://expedi-
tions.mnhn.fr/). This was followed in 2012 by the “Our Planet
Reviewed” Papua Niugini Biodiversity Expedition (hereafter
PAPUA NIUGINI) which included an intensive study of the
Madang region and a deep-sea cruise off the Bismarck Sea
coast, from Vitiaz Strait to the border with West Papua (Irian
Jaya). The main targets of the cruise were to survey the diver-
sity of the fauna of (i) hard bottoms that are typically found on

carduelis Watson, 1882 (by original designation); living,
southeastern Australia and New Zealand.
Remarks. ― The genus Pagodula Monterosato, 1884 was used
by Houart (2001) for several species of the Indo-Pacic and
western Atlantic. It was later also used in various articles and
recently by Marshall & Houart (2011). A genus used for similar
looking shells, Enixotrophon Iredale, 1929, was considered a
synonym of Pagodula by Marshall & Houart (1995). However,
DNA analysis has now determined this genus to be valid (Barco
et al. 2015) and to include some Indo-Pacic species, including
those treated in this article.
The shell morphology of many of the species grouped
in Enixotrophon is similar to that of Pagodula echinata
(Kiener, 1840), the type species of Pagodula, but this latter
genus is currently restricted to a few species occurring in the
Mediterranean and the eastern and western Atlantic.

living at 523-706 m (this paper).
Remarks. ― Enixotrophon obtusus is similar to E. lochi
(Marshall & Houart, 2011), but differs in having a larger
protoconch (width 730-750 µm versus 630-650 µm), a lower
spire and in being larger relative to the number of teleoconch
whorls. Only small shells of juveniles, not exceeding 9 mm,
were collected during these two expeditions.

However, after study of new material from Mozambique
(MNHN, all juveniles) and examination of the protoconchs
of shells of both populations, it was clear that the specimens
from Mozambique have a much smaller and narrower proto-
conch compared to juvenile specimens from French Polynesia
and Papua New Guinea of the same length (550-600 µm ver-
sus 750-800 µm). We prefer to wait for more adult and intact
material from Mozambique, and/or DNA analyses to assess
the synonymy, and for now consider Trophon johannthielei as
a valid species of Enixotrophon.
MURICIDAE INCERTAE SEDIS
Genus Actinotrophon Dall, 1902
Actinotrophon Dall, 1902: 534. Type species: Trophon actino-
phorus Dall, 1889: 206 (by monotypy); living, western
Atlantic.
Remarks. ― Ongoing genetic studies (Barco et al. 2010, 2012;
Claremont et al., 2011, 2013a, b) are leading to a profound
reorganization of the systematics of the Muricidae and more
recently, Barco et al. (2015: 488) recast Actinotrophon to full
generic rank in Muricidae incertae sedis. Living species of
Actinotrophon have shell and radular morphologies congruent
with their inclusion in Pagodulinae, but DNA data are not yet
available to conrm this hypothesis (Barco et al. 2015).

144°06'-147°36'E, living at 410-460 m, shells in 410-520 m.
Etymology. ― Named after Sarah Samadi (MNHN), chief
scientist of the BIOPAPUA and PAPUA NIUGINI cruises.
Description. ― Shell to medium sized for the genus, up
to 12.6 mm in length at maturity (PAPUA NIUGINI: stn
DW3992). Length/width ratio 1.8-1.9. Broadly lanceolate,
lightly built, slightly squamous. Subsutural ramp narrow,
weakly convex.
Remarks. ― This species was described from a few specimens,
all from deep water off New Caledonia, living at 503-610 m and
collected by dredging and trawling around the island. Another
specimen from Port Hedland, Western Australia was also listed
in the original description.
Other specimens, all collected living at similar depths,
have been recorded since then in a few other localities (see
Distribution).

Type locality. ― Southwest Pacic, Waterwitch Bank, 12°30'S,
176°41'W, 325-400 m [MUSORSTOM 7: stn DW537].
Material examined. BIOPAPUA: stn DW3745, seamount off
Bougainville, 05°33'S, 154°00'E, 369-377 m, 1 dd.
Distribution. ― Southwest Pacic, Waterwitch Bank and Wallis
and Futuna (MUSORSTOM 7), Vanuatu (MUSORSTOM 8),
Fiji (MUSORSTOM 10, Houart & Héros 2008), Solomon
Islands (SALOMON 1) and Papua New Guinea (this paper),
living at 325-419 m.
Remarks. ― Actinotrophon tenuis differs from A. fragilis
in having a shorter, broader siphonal canal relative to the shell
length. The shoulder spines are broader, shorter, more broadly
open, less acute, more backwardly recurved, and more adapi-
cally bent. The teleoconch whorls are higher and more adapi-
cally carinate. On the last teleoconch whorl of adult A. tenuis,
the preceding axial lamella almost entirely cover the succeeding
spine on the subsutural ramp; these lamellae are narrower and
less expanded in A. fragilis.
Actinotrophon tenuis was described from two specimens
but as for the preceding species other specimens have been
collected during subsequent expeditions extending its geo-
graphical distribution north-northwest of the type locality.
Living specimens have been collected in shallower depths
than A. fragilis.

Remarks. Leptotrophon wareni was described from the
Solomon Islands and was then known by only four empty
shells collected in 318-570 m. The discovery of two empty
shells and one live collected specimen extends considerably
its geographical distribution.
Genus Nipponotrophon Kuroda & Habe, 1971
Nipponotrophon Kuroda & Habe, 1971: 233 (in Kuroda, Habe
& Oyama 1971). Type species: Boreotrophon echinus Dall,
1918 (by original designation); living, Japan.
Remarks. The new species described below is more related
to Nipponotrophon than to Scabrotrophon. The shell is almost
smooth with very low and shallow primary spiral cords and a
smooth shoulder ramp starting from the rst teleoconch whorl;
it also has a strong angulation, approximately situated mid-
whorl, as observed in the type species of Nipponotrophon. See
also under Scabrotrophon.
Shell entirely white. Spire high with 1.5 protoconch whorls
and up to 4 broad, strongly convex, nodose whorls. Suture of
whorls impressed. Protoconch large, whorls rounded, smooth,
maximum width 700-800 µm. Terminal lip shallow.
Axial sculpture of teleoconch whorls consisting of numer-
ous, low, narrow, fronded lamellae. First whorl with 9-12
lamellae, second with 11-13, third with 13 and last with 12-14.
Spiral sculpture of low, strong, rounded, narrow, smooth pri-
mary and secondary cords. First whorl of adult shells with 2
visible primary cords. Shoulder ramp smooth. Cords increas-
ing in number abapically: 4 on second, 6 on third and 10-12 on
last teleoconch whorl, consisting of 6 primary cords and 4-6
secondary cords of approximately same strength. Secondary
cords occasionally missing, narrower and/or very shallow.
Cords more strongly crowded on abapical part of last teleo-
conch whorl. More or less visible IP cord on penultimate and
last whorls. Axial lamellae more strongly developed when
crossing spiral cords, forming vaulted squales.
Aperture large, ovate. Columellar lip broad, smooth. Rim
strongly erect abapically, a small portion adherent at adapical
extremity. Anal notch shallow, broad. Outer lip smooth, with
very low ID, followed by low or shallow D1 to D5, occasion-
ally with some denticles obsolete. Siphonal canal short, 20%
of shell length, narrow, straight, tapered abapically, open, with
shallow ADP, MP and ABP, occasionally with secondary ads,
ms and abs cords.
Operculum and radula unknown.
Remarks. ― No radula or operculum characters could be
examined but the shell characters of Conchatalos samadiae
spec. nov. are similar to other species of this genus, of which
four are known from New Caledonia (Houart 1995) and one
from Fiji (Houart & Héros 2008). Conchatalos samadiae
differs from the most similar species, Conchatalos tirardi
(Houart, 1991) (Pl. 4 Fig. 6) from southern New Caledonia,

Houart, R. & Héros, V. – Deep water muricids from PNG
erately long, 28-30% of shell length, narrow, weakly dorsally
recurved, open, with narrow, rounded ADP.
Operculum light brown or light greenish-brown, ovate,
inverted tear-shaped with apical nucleus. Attached surface
with broad, large callused rim. Radula (Textg. 1; Pl. 11 Figs
1a-b) of three-dimensional type (Herbert et al. 2007) with a
rachidian tooth bearing a long, broad, projecting central cusp,
a narrow, shorter inner denticle, a broad, triangular, lateral
cusp, few marginal folds and a single, obvious marginal cusp.
Lateral tooth sickle shaped with moderately broad base.
Remarks. ― Nipponotrophon barbarae spec. nov. differs
from N. echinus (Dall, 1918) (Pl. 5 Fig. 4) in having a com-
paratively broader and stouter shell with a lower spire and a
shorter, narrower siphonal canal. Nipponotrophon barbarae
also has a less spinose shell with atter spines and a different
spiral sculpture morphology with almost equidistant P1-P5
cords in N. echinus while P1, P2 and P3 are broadly separated
in N. barbarae.
Nipponotrophon barbarae spec. nov. also differs from N.
gorgon (Dall, 1913) (Pl. 5 Fig. 5), which also has P1-P4 on the
convex part of the teleoconch whorls, but the P2 cord is more
obvious then in N. barbarae and all cords are more or less equi-
distant. Nipponotrophon barbarae also has a stouter shell with
comparatively broader teleoconch whorls, a lower spire and
atter spines at the intersection of P1 and the axial lamellae.
Nipponotrophon barbarae is more similar to N. magnicus
(Golikov & Sirenko, 1992) (Pl. 5 Fig. 6) from the Kurile
Islands, but it also differs by having a comparatively broader
shell and a less high spire. N. barbarae also has lower spire
whorls and atter spines. Moreover, in N. magnicus the spines
are narrower and more adapically curved, s2 is occasionally
present from second teleoconch whorl and the siphonal canal
is smooth.
Genus Scabrotrophon McLean, 1996
Scabrotrophon McLean, 1996: 93. Type species: Trophon
maltzani Kobelt, 1878 (by original designation); living,
northeastern Atlantic.
Remarks. Scabrotrophon was established to include
northeastern Pacic species with two dominant spiral cords
(P1 and P2) on the early sculpture and strongly scabrous
spiral cords on adult whorls. It was originally compared with
Boreotrophon P. Fischer, 1884, but Boreotrophon species
differ in having dominant axial sculpture and in having spiral
sulpture (when present) that does not override the axial ribs as
in Scabrotrophon species.
The species of Trophonopsis Bucquoy & Dautzenberg, 1882
are also similar but differ in having dominant axial rather
than spiral sculpture in the early whorls. The prominent axial
ribs in Trophonopsis species are overriden by spiral sculpture
forming beads at their intersections.
Species of Scabrotrophon were also compared with
Nipponotrophon species, but the latter differ by having a
Nipponotrophon barbarae spec. nov.

Distribution. ― Vanuatu (MUSORSTOM 8), Solomon Islands
(Houart & Héros 2012); Papua New Guinea (this paper), living
at 307-1136 m.
Remarks. The holotype of Scabrotrophon inspira-
tus (Pl. 2 Fig. 3; Pl. 6 Figs 1a-b) was collected during the
MUSORSTOM 8 cruise to Vanuatu in 1994 but the shell char-
acters were misleading and the specimen was rst believed
to be coralliophiline. Reconsideration of the previous analysis
and comparison with other material prompted its description
as a Scabrotrophon species. Only two adult specimens, both
empty shells, collected at 1360 m were studied at that time.
A few additional specimens were gathered some years later
during the SALOMON 1 (2001) and SALOMONBOA 3 (2007)
cruises (Pl. 6 Figs 2a-b) of which two were live collected. We
could therefore illustrate the radula (Houart & Héros 2012: g.
5B), leaving no doubt about its relationship with the Muricidae
and with the Trophoninae in particular. Living specimens
where then collected at 1136-1138 m.
strong mid-whorl, or approximately mid-whorl angulation at
all growth stages, and by having a smoother shell with less
extensive spiral sculpture at the adult stage. Moreover, the
shoulder ramp in Nipponotrophon species is smooth compared
to the usually strongly sculptured ramp in Scabrotrophon spe-
cies in which IP is usually starting from the rst whorls with
additional adis, abis and occasionally tertiary spiral cords on
the penultimate and last whorls.
Scabrotrophon was originally considered to be restricted
to the Northern Hemisphere but is evidently more dispersed
throughout the Pacic. The species in this paper are similar to
the northeastern Pacic species in axial and spiral sculpture
and in gross shell morphology.

Distribution. ― North and east Papua New Guinea, 02°13'-
09°17'S and 145°37'-147°29'E, living at 470-1000 m.
Etymology. ― Named after Ralph Mana, professor at
University of Papua New Guinea, and the counterpart of Sarah
Samadi and Philippe Bouchet for the MNHN expeditions in
Papua New Guinea. Dr Mana was a participant in both the
BIOPAPUA and PAPUA NIUGINI expeditions.
Description. ― Shell large for the genus, up to 40.2 mm
in length (stn CP3967). Length/width ratio 1.4-1.7. Biconical,
broad, strongly spinose, lightly built, squamous. Subsutural
ramp broad, weakly sloping, weakly convex.
Shell entirely white or dirty white. Spire high with 1.8-2
protoconch whorls and up to 5-5.5 broad, angulate, strongly
shouldered, spinose and squamous teleoconch whorls. Suture
impressed. Protoconch large, broad, bulbous, often eroded.
Whorls rounded, smooth. Maximum width 1300-1700 µm.
Terminal lip indistinct but junction of protoconch and teleo-
conch whorls well delimited.
Axial sculpture of teleoconch whorls consisting of low,
broad, spinose lamellae with long, attened, weakly or strongly
abaxially recurved, open spines at intersection of axial lamel-
lae and spiral cords, giving a strongly spinose appearance to
the shell. Spines on P1 broadest and longest, strongly attened
at base, tapered at extremity, P2 spines short, P3-P4 spines
slightly longer, equal sized, P5 spines very short or obsolete.
First whorl with 9-12 lamellae, second with 11-13, third with
11-14, fourth with 12 or 13, last whorl with 10-14. Spiral sculp-
ture of high, strong, rounded, narrow, smooth primary cords.
First to fourth whorl of adult shells with visible P1 and P2,
P2 weakly narrower. Last whorl of holotype with P1-P5, ADP,
MP, ABP, abs. Other specimens often with obsolete P5, ABP
and abs. Shoulder ramp smooth except low axial lamellae.
Aperture large, broad, roundly-ovate. Columellar lip broad,
ared, smooth. Rim erect abapically, a small portion adher-
ent at adapical extremity. Anal notch shallow, broad. Outer
lip weakly erect, smooth, smooth within. Siphonal canal mod-
erately long, 30-33% of shell length, narrow, straight, very
weakly dorsally recurved at tip, open, with narrow, weakly
spinose ADP, MP, (ABP).
The impressive material from the BIOPAPUA and the
PAPUA NIUGINI expeditions gave us the opportunity to
examine numerous specimens, from the juvenile stage with
shells consisting of 2 or 3 teleoconch whorls to fully adult
shells with 6 teleoconch whorls, reaching a length of 50.2 mm
(Pl. 6 Figs 5a-c). This was also an opportunity to observe the
variability of the shell characters and to redene the spiral
sculpture morphology. It soon became clear that what was
considered as a s4 cord (Houart 2003: g. 1) was in fact a nar-
row P5 cord, followed by ADP, ads, MP and ABP (Pl. 2 Fig.
3). This was conrmed in examining a few juvenile shells and
other species of this genus.
The shell characters are also variable, as in many muric-
ids. The P1 and P2 cords are present from rst to last teleo-
conch whorl and they gradually move away from each other to
become broadly separated on the last whorl with an occasional
s1 cord between them. The number of axial lamellae of the last
teleoconch whorl is also very variable, from 8 to 13 (Pl. 6 Fig.
5b, Pl. 7 Figs 1b and 5b), while the shell may be stout (Pl. 7 Figs
3-4) to moderately elongate (Pl. 6 Figs 3, 5a) or more angular,
but in our opinion these represent only normal intraspecic
variation.
On the other hand, the big, broad and irregular protoconch
(Pl. 6 Fig. 4, Pl. 7 Figs 2-b) attests to an intracapsular larval
development.

Description. — Shell medium sized for the genus, up to
Operculum brown, ovate, inverted tear-shaped with apical
nucleus. Attached surface with broad, callused rim.
Radula unknown.
Remarks. Scabrotrophon manai spec. nov. is similar to
S. inspiratus Houart, 2003 but in S. manai the P1 and P2 spiral
cords are more narrowly separated from each other from rst
to last whorl [see for example Pl. 7 Figs 3, 5a, 5c (S. inspira-
tus) versus Pl. 8 Figs 1a-b, 5-7 (S. manai)]. The convex part
of the last teleoconch whorl in S. inspiratus is more angulate
and bears P1-P5, P4 being mostly very narrow or obsolete; s2
is very occasionally present from second to penultimate or
last whorl. These differences are observed in all the numer-
ous examined specimens and no intermediate forms have been
encountered. Scabrotrophon manai and S. inspiratus were col-
lected together in 8 out of 10 stations during the BIOPAPUA
expedition (stn CP3652, CP3653, CP3672, CP3689, CP3709,
DW3739, CP3741 and CP3744) and in one out of 5 stations
during PAPUA NIUGINI (stn CP4079).
Scabrotrophon manai spec. nov. differs from S. regina
(Houart, 1985) (Pl. 9 Fig. 7) from the Philippines in having
narrower spire whorls, a narrower and longer siphonal canal,
and a smooth shoulder ramp, in contrast to S. regina, which
has a IP cord from third teleoconch whorl and adis with IP
on last whorl. S. manai spec. nov. also has comparatively nar-
rower spiral cords and rather longer spines.
Scabrotrophon manai spec. nov. differs from S. lani Houart
& Sun, 2004 (Pl. 9 Figs 1-2) from southern Japan by having
obviously less strongly convex teleoconch whorls, a smooth
subsutural ramp except for the axial lamellae, as opposed to
the presence of IP and adis from second to last teleoconch
whorl in S. lani, and in lacking secondary spiral cords, while
these are present between each pair of primary cords in S. lani.

and south of New Hanover, living at 307-1019 m.
Etymology. Named after Nicolas Puillandre, molecular
malacologist at MNHN and a participant of the Papua Niugini
Biodiversity Expedition.
Description. ― Shell small for the genus, up to 16.1 mm
in length at maturity. Length/width ratio 1.7-1.8. Lanceolate,
spinose, lightly built. Subsutural ramp broad, weakly sloping,
weakly convex.
Shell entirely white. Spire high with 1.25 protoconch whorls,
up to 5.5 elongate, narrow, strongly shouldered, spinose teleo-
conch whorls. Suture of whorls impressed. Protoconch large,
whorls rounded, smooth. Maximum width 900 µm. Junction
of protoconch and teleoconch whorls distinct but terminal lip
obsolete.
Axial sculpture of teleoconch whorls consisting of low, nar-
row, frondose lamellae with long, blunt, narrow, open, weakly
abaxially recurved, vaulted spines at intersection with all spi-
ral cords, giving a strongly spinose appearance to the shell.
Spines on P1 longest, weakly decreasing in strength from P2
to P5, small on ADP and MP. First whorl with 9 or 10 lamel-
lae, second with 10-12, third with 12-15, fourth with 13-16,
last whorl with 15 or 16 spinose lamellae. Spiral sculpture of
high, strong, narrow, spinose, primary, secondary and tertiary
cords. First teleoconch whorl of adult shells with visible P1
and P2, second whorl with P1 and P2, occasionally starting
s1, third and fourth whorls with P1, s1, P2, P2 occasionally
ing whorl, second whorl with P1-P3, third whorl occasionally
starting s2, fourth whorl of a juvenile shell with P1, P2, s2,
P3, P4, P5, s5, fth with P1, s1, P2, s2, P3, P4, s4, P5, s5, sixth

ond or third whorl; last whorl with adis, IP, abis and additional
tertiary cords.
P1 with small, broad, vaulted scales where crossing axial
lamellae; other cords with smaller and less obvious scale at
intersection with lamellae. Siphonal canal with ADP, ads, MP,
ms, ABP and few, vaulted scales.
Aperture moderately large, ovate. Columellar lip broad,
ared, smooth. Rim partially erect, adherent at adapical
extremity. Anal notch shallow, broad. Outer lip smooth with
obsolete denticles within. Siphonal canal short, 23% of shell
length, straight.
Operculum and radula unknown.
Remarks. Scabrotrophon maranii spec. nov. is similar
to the shells of the S. lasius group from the eastern Pacic
(McLean 1996) and particularly to S. grovesi McLean, 1996
(Pl. 9 Fig. 6). However, it differs by having a comparatively
shorter siphonal canal, more numerous, secondary and ter-
tiary cords, more numerous axial lamellae and a shoulder
ramp with spiral cords, while there are only axial lamellae
in S. grovesi.
Scabrotrophon maltzani (Kobelt & Küster, 1878) (Pl. 9 Fig.
5), another eastern Pacic species, differs in having broader,
more numerous, less squamous spiral cords, more numerous
primary and secondary spiral cords on the visible part of early
teleoconch whorls in adult shells and in having a compara-
tively broader aperture.
Scabrotrophon regina (Houart, 1986) (Pl. 9 Fig. 7) from the
Philippines has less numerous, more frilly and higher axial
lamellae, a less high spire, broader and fewer spiral cords and
broader, more obvious, vaulted scales.

Axial sculpture of teleoconch whorls consisting of low,
narrow, frondose lamellae and low, weak, narrow growth
lamellae. Intersection of axial lamellae and spiral sculpture
giving frilled appearance to the shell, forming narrow, small,
vaulted scales at their intersections. First and second whorls
with 10 lamellae, third with 10 or 11, penultimate and last
with 10-13. Spiral sculpture of low, rounded, narrow, weakly
squamous, primary, secondary and tertiary cords. First, sec-
ond and third teleoconch whorls of adult shells with visible
P1 and P2, fourth with (abis), IP, adis, P1, s1, P2, s2, P3; P3
partially covered by following whorl. Last teleoconch whorl
with (adis), IP, abis, (t), P1, (t), s1, (t), P2, (t), s2, (t), P3, s3, (t),
P4, (s4), P5, (s5), ADP, ads, MP, ms, (ABP). P1-P4 similar in
strength; P5 weakly smaller. Secondary cords narrower but
moderately large.
Aperture large, broadly ovate or ovate. Columellar lip nar-
row, smooth except small abapical node, rim erect, ared, a
small portion adherent at adapical extremity. Anal notch shal-
low, broad. Outer lip weakly erect, smooth, with obsolete or
shallow ID, broad, high D1 and narrow D2, D3 and D4, or
D3-D4 fused, weakly higher. Siphonal canal moderately long,
31-33% of shell length, broad, straight, open, with narrow, low
ADP, ads, MP, ms spiral cords.
Operculum and radula unknown.
Remarks. Scabrotrophon maestratii spec. nov. is different
from any other Scabrotrophon species from the west Pacic
and from Papua New Guinea in particular. The outline of the
shell is reminiscent of the genus Conchatalos but the frilled
appearance, the vaulted scales at the intersections of axial
lamellae and spiral cords, the width and height of the spire and
the length of the siphonal canal are characters similar to other
Scabrotrophon species.

Full-text available
Fourteen species of Muricidae referable to the (sub)genera Promurex Ponder & Vokes, 1988, Pygmaepterys Vokes, 1978, Murexsul lredale, 1915, Pazinotus Vokes, 1970, Prototyphis Ponder, 1972, Ponderia Houart, 1986, Gemixystus Iredale, 1929, Leptotrophon Houart, 1995 and Scabrotrophon McLean, 1996 are reported from New Caledonia, the Solomon Islands and Taiwan, to depths down to 1750 m. Five new species are described: Favartia (Pygmaepterys) lifouensis n. sp. from New Caledonia with range extension to the Solomon Islands, Pazinotus chionodes n. sp. and Gemixystus calcareus n. sp. from New Caledonia, Leptotrophon wareni n. sp. from the Solomon Islands and Favartia (Pygmaepterys) circinata n. sp. from Taiwan.

The deep-sea part of the "Papua Niugini Biodiversity Expedition" surveyed the deep-sea environments along the coasts of New Guinea Island in the Bismarck Sea, from the Vitiaz Strait to the border between Papua New Guinea (PNG) and Irian Jaya. This expedition was a follow-up of the BIOPAPUA cruise (2010) that gave some of the first insights into the diversity of the deep-sea fauna of the Bismarck and Solomon Seas for environments other than deep-sea hydrothermal vents. The main targets of the cruise were to survey the diversity of the fauna of (i) hard bottoms that are typically found on deep seamounts, (ii) Astrolabe Bay from 200 m to about 1000 m, (iii) the chemosynthetic environments of the deep sea, including cold-seep environments and plant debris. The Astrolabe Bay was one of our targets because its topography allows sampling over the complete bathymetric gradient covered by our sampling gears (down to 1000 m depth), and the recent start of nickel refining activities in the bay is a potential threat to a marine fauna for which little reference data are available. Sampling in the bay has revealed not only a diversified fauna associated with soft bottoms and plant debris, but also a chemosynthetic fauna typical of cold-seep environments (e.g. siboglinid worms and bathymodioline mussels) below the Ramu refinery. Although the refinery activities had officially started just one week before our work in the area, an impact of its activities is already observed. Our molecular work indicates that the siboglinid tubeworm species and one of the two mussel species collected below the Ramu refinery have so far only been documented from this location, despite an important sampling effort. This illustrates the potential destructive effects of human activities in areas where the diversity and uniqueness of deep-sea communities are poorly understood.

We investigated the relationships of the muricid subfamilies Haustrinae, Pagodulinae and the genus Poirieria using a molecular phylogenetic approach on a dataset of three mitochondrial genes (12S, 16S and COI). These taxa form a well-supported clade within Muricidae. The phylogenetic analysis suggests that Poirieria is the sister group of Pagodulinae and that Axymene, Comptella, Pagodula, Paratrophon, Trophonella, Trophonopsis, Xymene, Xymenella, Xymenopsis and Zeatrophon are all worthy of genus-level rank within this subfamily. We propose the use of Enixotrophon for a group of species currently classified in Pagodula. The results also support a new taxonomic arrangement in Haustrinae.

The validity of the muricid subfamily Ergalataxinae has recently been confirmed with molecular data, but its composition and the relationships among its constituent genera remain unclear. In order to investigate this, we use four genes (28S rRNA, 12S rRNA, 16S rRNA and cytochrome c oxidase subunit I) to construct a Bayesian phylogeny of 52 ergalataxine species in 18 genera, representing c. 40% of the currently accepted species and 86% of the genera. This is the most complete phylogeny of this taxonomically confusing subfamily yet produced. Our results indicate the polyphyly of many traditional genera, including Morula, Pascula and Orania. In order to improve the correspondence between classification and phylogeny, we restrict the definition of Morula, resurrect Tenguella and elevate Oppomorus to full genus, but describe no new genera. Several species in this analysis could not be identified and may be new, but we do not describe them. Further molecular and morphological analyses, in the context of this framework, should help to resolve the remaining ambiguities in the classification of this subfamily. The oldest fossil member of the Ergalataxinae known to us is of Early Oligocene age.
