Two species of Eviota with red or orange bars crossing the body, a bifurcated 4th pelvic-fin ray with two long branches,
and lacking many or all cephalic sensory-canal pores are described from Palau, Indonesia, and Papua New Guinea. Eviota
jewettae has a dorsal/anal fin-ray formula of 8/8, 98% of the specimens lack all cephalic sensory-canal pores, 2–4 lower
pectoral-fin rays branched; non-filamentous dorsal-fin spines; short tubular anterior nares that are not black and are less
than ½ pupil diameter in length, and five wide bars across the body. Eviota pinocchioi has a dorsal/anal fin-ray formula
of 9/8, always lacks the POP and IT pores and the PITO and AITO pores are fused in about 50% of the specimens, un-
branched pectoral-fin rays, males with filamentous dorsal-fin spines, tubular anterior nares black and very long, almost
equal to the pupil diameter, and six narrow bars across body.
Key words: Eviota jewettae, Eviota pinocchioi
While collecting gobiid fishes in Palau, Indonesia, and New Britain, Papua New Guinea the second author obtained
two species of Eviota with distinctive red or orange bars crossing the body and lacking a number of the cephalic
sensory-canal pores usually found in other species of Eviota. Both species have been illustrated in Dimara et al.
(2010), one as Eviota Palau sp. 2 and the other as Eviota Raja Ampat sp. 2 (live) and Eviota Palau sp. 6 (preserved).
These two species are described here. As is typical of all species of Eviota, the pelvic fins are separate and the 5th
pelvic-fin ray, if present, is unbranched; there are ctenoid scales on the body; no scales on the head, nape or
pectoral-fin base; the basal membrane of the pelvic fins is rudimentary or absent; and the teeth in the upper jaw are
in two or more rows.
Material and methods
Counts and measurements, descriptions of fin morphology and the cephalic sensory-canal pore patterns follow
Lachner and Karnell (1980). Measurements were made to the nearest 0.1 mm using an ocular micrometer and dial
calipers, and are presented as percentage of Standard Length (SL). All specimen lengths are SL in mm. Cyanine
Blue 5R (acid blue 113) stain was used to make pores more obvious (Akihito et al. 1993; Saruwatari et al. 1997;
Nakabo 2002) and an airjet used to observe them. For measurements, values for the holotype are given first,
followed by the range for all types and the mean in parentheses. Uchelbeluu Reef, off the S.E. corner of Koror
Island, has also been called the Short Drop-Off or Augupelu Reef by various authors. Specimens have been
deposited in the following museums: AMS—Australian Museum, Sydney; CAS—California Academy of
Sciences, San Francisco; ROM—Royal Ontario Museum, Toronto, and USNM—United States National Museum
(Smithsonian), Washington D.C.

65.8 (56.5–65.8, 61.7); caudal-peduncle length 23.5 (21.6–26.6, 23.8); caudal-peduncle depth 12.3 (11.7–13.2,
12.4); body depth 20.6 (19.3–25.0, 21.5); eye diameter 11.5 (9.6–12.9, 11.0); snout length 6.2 (5.2–6.3, 5.6); upper-
jaw length 11.5 (10.8–13.7, 12.0).
Color in preservative of holotype (Fig. 1). Background color of head and body pale yellowish. A few
scattered small melanophores on top of the head directly behind the eyes, but no other dark pigment on the head.
No dark markings on body, but a few melanophores on the gut show through the translucent sides of the abdomen.
Caudal, pectoral and pelvic fins immaculate. A light peppering of small melanophores on basal and dorsal thirds of
the first dorsal fin. A few scattered melanophores on the anterior portion of the second dorsal fin. Distal half of the
anal fin with a peppering of melanophores.
Color in preservative of paratypes. A number of the paratypes from Palau show more dark pigmentation
than is present in the holotype. There often is a concentration of melanophores along the anal-fin base that extends
back along the caudal peduncle to the caudal-fin base. A few scattered melanophores may be present at the center
of the pectoral-fin base. There may be a peppering of melanophores behind the eyes extending back across the nape
to the dorsal-fin origin and then on the dorsum along the dorsal-fin bases. Most of the first dorsal-fin membranes
heavily peppered with melanophores. A few specimens have a series of dark subcutaneous bars crossing the body.
All have melanophores on the gut that show through the translucent sides of the abdomen (Fig. 2, ROM 93605).

TWO NEW DWARFGOBIES FROM THE SOUTHWESTERN PACIFIC OCEAN
Color of fresh paratype (Fig. 5, ROM 93605, Palau). Background color of head and body translucent white.
Body crossed by five wide orange bars plus a narrow bar at the caudal-fin base: the first from the front of the first
dorsal fin down behind the pectoral-fin base; the second at the posterior end of the first dorsal fin, curving down
across the abdomen towards the anus; the third at the second element of the second dorsal fin extending down to
the anal-fin origin; the fourth at the sixth element of the second dorsal fin extending down to the anal fin; the fifth
across the caudal peduncle; the caudal-fin base crossed by a narrow bar that extends a short distance onto the
caudal fin; some dark pigment on the ventral edge of the bars on the anal fin and caudal peduncle. Nape orange,
crossed by three narrow white lines. Top of head, snout, nares, and operculum orange. Cheek under and behind eye

red on basal half of first three elements, membranes between them black. A small clear area above this followed by
similar coloration on the distal portion. A clear area along the basal portion of the next three elements extending up
to meet the clear area at the middle of the anterior portion of the fin. Posterior half of fin with dark red spines and
black pigment on the membranes. Basal one-quarter of spine of second dorsal fin clear, the remainder red. The
lower half of the next rays are red from the third body bar extending up onto it, overlaid with black pigment, and
the upper half has clear rays and reddish membranes peppered with small melanophores. The space between the
third and fourth ray is clear, with the light area extending distally. The remainder of the fin is dark from the fourth
body bar and is overlaid by a peppering of melanophores. Anal fin with body bars extending onto it entire length,
and entire fin overlaid with a peppering of melanophores. Caudal, pectoral and pelvic-fin rays reddish and overlaid

FIGURE 7. Freshly collected specimens of Eviota jewettae from Halmahera, Indonesia. Photograph by G.R. Allen.
A photograph of three specimens of E. jewettae from Raja Ampat, Indonesia taken by G.R. Allen (Fig. 7 ),
shows some variation in the bands crossing the body. Figure 8 is an underwater photograph of a live E. jewettae
taken at Waigeo Island, Indonesia.
Distribution. Known from Palau, Philippine Islands, Papua New Guinea and Raja Ampat, Indonesia. In Palau,
the species is currently known only from Helen Reef, the southern-most of the South West Islands, and has not yet
been found at the main island group to the north.
Etymology. This species is named for Susan L. Jewett who previously recognized this species as undescribed
from specimens taken by the Smithsonian Philippine Expedition in 1978. During the 1970’s and 1980’s she,
sometimes under the name Karnella, and E.A. Lachner described many Eviota species new to science and laid the
foundation for the study of this genus.
Comparisons. Eviota jewettae is the only described species almost always completely lacking all cephalic
sensory pores, although we are aware of some other possible undescribed species that also lack pores.
Remarks. Cutaneous papilla may be located at the location of pore sites and mistaken for pores, especially in
the interorbital area. Stain and the use of an airjet are helpful in distinguishing between these.
As noted above, there are differences in the live and preserved coloration between the specimens from Palau and
those from other locations to the south. In fresh material the Palau specimens have orange bars crossing the body
and little dark pigmentation, whereas those from Indonesia and Papua New Guinea have reddish colored bars and
much dark pigmentation. We do not have information on the fresh coloration of the USNM specimens from the
Philippines, but the preserved material exhibits dark bars crossing the body as do those from Indonesia and Papua
New Guinea. In one lot of 66 specimens from Palau, only a few showed any indication of dark barring. Because of
these differences we have restricted the type material to Palau in the event that future DNA studies show them to be

62.3 (57.7–66.0, 62.2); caudal-peduncle length 22.9 (20.5–26.9, 24.3); caudal-peduncle depth 13.8 (10.3–13.8,
12.4); body depth 20.3 (20.1–23.9, 21.6); eye diameter 10.2 (9.9–11.9, 10.6); snout length 5.2 (5.2–6.7, 5.8); upper-
jaw length 10.5 (9.6–12.7, 11.5).
Color of holotype in preservative (Fig. 9, ROM 76361). Background color of head and body pale yellowish.
No bold dark markings on body. A line of melanophores along ventral surface of caudal peduncle. Head with a few
small mealnophores behind center of eye, and several clusters of larger melanophores on top of head behind eyes.
Snout and center of upper jaw peppered with small melanophores. Anterior tubular nares black. Pupil and iris of
eye black. A few small melanophores on nape in advance of first dorsal fin. Basal half of pelvic fins dusky. Pectoral
fins immaculate. Caudal fin mostly clear with a few melanophores distally. Anal and soft dorsal fins with scattered
melanophores on rays and membranes. First dorsal fin with a dark band crossing base just above a clear portion
along base of fin near dorsum.
Color of fresh paratype (Fig. 10, ROM 80701). Background color of head and body translucent white. All
markings on body orange. Body crossed by six narrow bars: the first from the front of the first dorsal fin down
behind the pectoral-fin base; the second at the posterior end of the first dorsal fin, curving down across the
abdomen towards the anus; the third at the third element of the second dorsal fin extending down to the anal-fin
origin; the fourth at the sixth element of the second dorsal fin extending down to the anal fin; the fifth running from
behind the second dorsal fin down to the posterior end of the anal fin; and the sixth across the caudal peduncle. The
nape is crossed by two bars and there is a short bar between the two dorsal fins, another at the posterior end of the
second dorsal fin, with a corresponding bar below it at the anal fin, and two short bars at the dorsal and ventral
caudal-fin base. The central portion of the caudal-fin base also has a short bar. The area on top of the head behind
the eyes has a blotch and the opercular area has another. There are three narrow bars under the eye, the shortest at
the posteroventral margin, another ventrally under the eye and extending down across the jaws and the third at the
anteroventral edge and also crossing the jaws. Eye pupil black, iris sky blue with red-orange spokes surrounding
pupil. Base of anterior tubular nares orange, remainder black. The pectoral-fin base has two blotches, one at the top
and the other at the bottom, separated by a translucent white area. Second dorsal fin with brown spots on rays,
distal margin dusky. Upper half of caudal fin with brown spots on dusky rays. Anal-fin rays and membranes dusky.
Spines of first dorsal fin red-orange with first and second body bars extending onto lower one quarter of fin, a bar
of melanophores running across base just above a clear portion along base of fin near dorsum. Pectoral and pelvic

Distribution. Palau and possibly Indonesia. In Palau, the species has only been taken in the main island group
and the middle of the South West Islands (Merir I.).
Etymology. Named after Carlo Collodi’s fictional character Pinocchio, who had a nose that grew long when he
lied, alluding to the exceptionally long anterior tubular nares in this species.
Comparisons: Five other described Eviota species also lack only the POP and IT pores: E. lacrimae, E.

ocellifer, E. sparsa, and E. susanae. Eviota pinocchioi has non-fimbriate genital papillae, a dorsal-fin count of VI-
I,9 and unbranched pectoral-fin rays (vs. fimbriate papillae in both sexes, VI-I,8 and branched pectoral-fin rays in
E. susanae). The 5th pelvic-fin ray is 53–90% of the 4th pelvic-fin ray and some pectoral fin-rays are branched in E.
sparsa (vs. 6.5–15.3% and unbranched in E. pinocchioi). The pectoral-fin rays are branched in E. ocellifer (vs.
unbranched in E. pinocchioi). Eviota lacrimae has a dorsal-fin count of VI-I,8 and the 5th pectoral-fin ray is usually
absent (vs. VI-I,9 and present in E. pinocchioi). Eviota pinocchioi also differs greatly in live coloration from all of
Remarks: Three specimens were collected in Indonesia that have the identical color pattern of E. pinocchioi,
including the long black tubular anterior nares (Fig. 11). They are like E. pinocchioi in lacking both the POP and IT
pores, but in addition lack more pores that are present in that species. ROM 85364 also lacks the PITO, SOT, and
AOT pores. CAS 234099 and 234827 lack all pores. Often very small specimens may lack pores, but CAS 234099
is 15.3 mm, CAS 234827 is 14.8 mm, and ROM 85364 is 18.3 mm. In addition, E. pinocchioi has 15–16 (usually
16) pectoral-fin rays, whereas the Indonesian specimens have 16, 17 and 18. Because the Indonesian specimens
share this unique color pattern with E. pinocchioi, have the same measurements and structure of the fourth pelvic-
fin ray (bifurcated with branches about 50% of total length of the ray), we are hesitant to treat them as a separate
species without further specimens and genetic information. Although the long black tubular anterior nares and
more simple bifurcated pelvic-fin rays are similar to those in species of Sueviota, Winterbottom and Hoese (1988)
did not list these as a synapomorphies for that genus. The branched 5th pelvic-fin ray and the basal membrane that
are present in Sueviota are lacking in E. pinocchioi and in all other species of Eviota.
Susan L. Jewett kindly made her notes on USNM Philippine specimens of Eviota jewettae and an illustration (Fig.
4) available to us. The staff of the California Academy of Sciences as usual has provided continual support: D.
Catania, J. Fong, M. Hoang, T. Iwamoto, and L. Rocha. RW's field work in Palau benefitted from the participation
of many people, but especially so from Pat Colin, Mark Westneat and Wouter Holleman—many thanks to all.
Gerry Allen and Mark Erdmann kindly allowed us use of their excellent photographs from Indonesia, and Mark
Erdmann provided numerous specimens. The curatorial expertise of Don Stacey and Margaret Zur (both ROM) is
gratefully acknowledged. Jeffrey Williams, Shirleen Smith, and Sandra Raredon (USNM) assisted with the loan of
