Abstract
Seventeen species of Strongylophthalmyia are recognized in the fauna of Vietnam, including eight new
species: S. annulipes sp. n., S. basisterna sp. n., S. dichroa sp. n., S. gavryushini sp. n., S. obtecta sp. n., S.
orchidanthae sp. n., S. stricta sp. n., S. tomentosa sp. n. Strongylophthalmyia angusticollis Frey, S. fascipennis
Frey, S. metatarsata Meijere, S. splendida Yang & Wang, and S. thaii Papp are recorded for the rst time
from Vietnam. e male of S. splendida and female of S. thaii are described for the rst time. A key to
34 species of Strongylophthalmyia of the fauna of Vietnam and continental southeast Asia, including the
Oriental southern region of China is provided.

Introduction
e Strongylophthalmyiidae is a small family of acalyptrate Diptera containing two
genera, Strongylophthalmyia Heller, 1902 and Nartshukia Shatalkin, 1993. e ge-
nus Nartshukia is known only by the single female specimen of Nartshukia musiva

Shatalkin, 1993 from Vietnam. e genus Strongylophthalmyia includes 54 species to
date, occurring in the Nearctic (two species), Palaearctic (eight species), Oriental (40
species) and Australasian (9 species) regions (Iwasa and Evenhuis 2014). Two species
described from Madagascar by Verbeke (1963, 1968) were transferred to Clusiidae by
Barraclough (2000). As our studies show, the Vietnamese fauna of the genus includes
17 species. Eight of them are described in this paper as new, and ve of them are re-
ported for Vietnam for the rst time.
Materials and methods
is study is part of an ongoing series of studies on the Vietnamese cyclorrhaphous
fauna. A key is composed for species from Vietnam, Burma, Oriental southern Region
of China and ailand; the genus has not yet been recorded from Laos or Cambodia.
e specimens of new species of Strongylophthalmyia described in this paper are rare
in our collection, and the colouration of the abdomen is important for determination;
hence, genitalic characters are not explored in the descriptions of new species.
Types of the new species are deposited in the collection of Zoological Museum of
Moscow University (ZMUM).
In the key and descriptions of species, morphological terminology, abbreviations
of wing veins, and wing cells, are after Cumming and Wood (2009). Measurements
are given in millimetres. Labels of specimens are quoted verbatim. Frontal index = the
ratio between height of the frons from its anterior margin to hind ocelli and from hind
ocelli to vertex or vti.
Results
e genus Strongylophthalmyia includes strikingly elegant ies with elongated bodies
and slender legs. ese ies have body lengths from 2.3 mm to 7.5 mm (the smallest is
S. palpalis Papp, 2006 the largest is S. gigantica Iwasa & Evenhuis, 2014).
Head (Figure 1a) is spherical or extended in prole (extended in S. splendida Yang
& Wang, 1996); the gena is narrow; the facial sclerotization is interrupted by mem-
brane medially; and the ocellar tubercle is moved forward and is often situated in the
middle of the frons. Females often have a large bulbous clypeus, but it is smaller and
band-like in males. First agellomere is short, rounded.
Several species of this genus have sexual dimorphism in the antennal structure. e
males of some Strongylophthalmyia dier in developing of the dorsal process of the rst
agellomere (Figure 10d, e).
e arista is usually bare, but several Oriental species have small setulae on the
arista. Males of some of these species groups have modied palpi, which can be yel-
low (compared to the black female palpus), bilobate and with black scales or thick
setulae. Chaetotaxy of head: 2–3 orbital setae, usually with three hair-like small frontal

setae, one ocellar seta, one inner vertical seta and one outer vertical seta (absent in S.
splendida), one postocellar seta, one paravertical seta (absent in some species), vibrissa
absent.
orax is coloured from yellow (Figure 6) to black (Figure 2b). Several species are
characterised by a black thorax, and a postpronotum and propleuron and often basis-
ternum that are entirely or partly yellow. Several species are black with a pair of reddish
yellow spots (in females) or one large spot (in males) on the basisternum between the
fore coxae (Figure 2e). Finally, two species, described in this paper as new, Strongyloph-
thalmyia obtecta sp. n. (Figure 5a,b) and Strongylophthalmyia stricta sp. n. (Figure 7a),
are black with brownish or yellowish spots on the postpronotum (laterally), and with
yellowish spots around the fore spiracles. ese two species may be related to Stron-
gylophthalmyia papuana Iwasa & Evenhuis, 2014 and Strongylophthalmyia gigantica
Iwasa & Evenhuis, 2014, both from Papua New Guinea, because these four species
are characterized by predominantly black legs. Since the black colouration of legs can
fade in preserved specimens, these species appear in multiple parts of the key. e me-
sonotum is covered with yellowish setulae or it is bare with black setae located in rows.
Chaetotaxy of thorax: 1 anepisternal seta, 2 notopleural setae (one notopleural seta
in Nearctic S. pengellyi Barber, 2006), 1 supraalar seta, 1 postalar seta, 1–2 dorsocen-
tral setae, 1 apical scutellar seta. Postpronotum usually with some setulae, rarely with
long setae. Strongylophthalmyia splendida has a strong black seta in the anterior part
of the mesonotum, near the postpronotum (Figure 9b: marked by arrow), which we
consider as sublateral (Hennig 1973: 184, Figure 109).
Legs are slender, usually bare. Hind legs of males of some species bear small papil-
lae, having one papilla on trochanter and two papillae on femur (these papillate protu-
berances are variable; some species with only on femur, others on both trochanter and
femur, some with just one, others up to three, some bare, others with long sti setae),
being bubble-like basally and conical (with yellow or black setulae) subbasally. Male
fore femur sometimes with short stout spines dorsally (Figure 4a).
Wings have a distinct costal break just before merging of costa and subcosta. e
subcosta is incomplete, not quite reaching the wing margin (Figure 1a). Transverse
vein CuA2 forms distal border of anal cell, convex. Veins R4+5 and M1 are parallel or
slightly converging in apical third. Vein A1+CuA2 is distinctly bent, not reaching wing
margin. Wing is transparent, wholly infuscated, with brownish apical spot or with
cross-band on dm-cu and short cross-band anteriorly level of Rs. Greater ampulla is
absent. Halter is coloured from whitish to yellow, rarely with blackish-grey knob.
Abdomen is slender, black, sometimes yellow, its colour patterns in some cases (S.
trifasciata Hennig, 1940) diers in females and males.
e structure of male genitalia are known only for several species of Strongyloph-
thalmyia (not for Nartshukia). Epandrium without surstyli (some authors (Iwasa 1998;
Iwasa and Evenhuis 2014) consider that surstyli are completely fused with epandrium).
However, genitalia of species of S. crinita group have appendages similar to surstyli and
attributed to this type of lobe (Shatalkin 1995). e hypandrium is well-developed,
bearing two pairs of lobes. e origin of these lobes remains unclear (Steyskal 1987,
Tatiana V. Galinskaya & Anatoly I. Shatalkin / ZooKeys 625: 111–142 (2016)
114
Shatalkin 1995, Iwasa 1998, Barber 2006, Lonsdale 2013, Iwasa and Evenhuis 2014).
Phallus and phallapodeme are very long; however, several exceptions are known. e
male of S. verrucifera Shatalkin, 1996 is characterized by a short apodeme of the ae-
deagus; on the contrary, males of S. paula Shatalkin, 1993 have truncated aedeagus.
Female terminalia have ovipositor quite elongate, slender, with unsclerotized
cerci. One or two (in S. pengellyi) spermathecae present (Iwasa 1998, Barber 2006).
Tergite and sternite 7 are fused into syntergosternite.
Ecology. Adult ies can be found on leaves of bushes and trees, on stumps, and
fallen logs. Larvae of some Holarctic species are characterised by biramous anterior
spiracles, and live under the bark of rotting logs of aspen (S. ustulata (Zetterstedt,
1847), S. pictipes Frey, 1935, S. angustipennis Melander, 1920, S. pengellyi) and under
bark of rotting logs of birch and elm (S. stackelbergi Krivosheina, 1981) (Krivosheina
1981, Barber 2006).
Notes. Neal L. Evenhuis in his review kindly noted that there is apparently a
serious mistake in Yang and Wang (1998) with regard to the description and wing
illustrations of S. splendida and S. yaoshana. e descriptions of the wing are either
switched or the illustrations are switched. Strongylophthalmyia splendida is described
as having a hyaline wing, yet the illustration claearly slows bands; whereas S. yaoshana
is described as having a banded wing, yet the illustration clearly shows it to have a
hyaline one. As the holotypes of each species are lost (Wang Xin li, pers. comm.; also
N.L. Evenhuis could not nd them during Wang’s and my search for them when N.L.
Evenhuis was in Beijing in 2014; only a paratype of S. bifasciata could be found) there
is no denitive way to determine which species is which.

Diagnosis. is new species belongs to a group of species characterized by a yel-
low postpronotum, propleuron and basisternum. ree species from this group, S. hu-
meralis, S. bifasciata and S. yaoshana are otherwise characterized by an arista with very
short setulae and easily dierentiated. Other species of this group, S. spinosa, S. thaii, S.
coarctata Hendel, 1913 and S. macrocera dier from S. annulipes by transparent wings.
Strongylophthalmyia annulipes sp. n. is close to S. tomentosa sp. n. and diers from it by
the presence of a preapical black ring on the mid and hind femora and by black ring on
the mid and hind tibia.
Description. Male. Head black, shining, slightly longer than its height; frons en-
tirely black, covered with grey tomentose of by very short setulae (0.01 mm). Occiput

Diagnosis. is new species strongly diers from all species from Vietnam and
neighbour countries. It is morphologically close to S. puncticollis Frey, 1928 (from
Philippines and Papua New Guinea) and to S. fasciolata Meijere, 1919 (from Su-
matra). Strongylophthalmyia. puncticollis diers from the new species by having the
abdomen entirely black; all femora have a brown preapical ring, the hind tibia is black
basally and apically and yellow in the median third. Strongylophthalmyia fasciolata dif-
fers from the new species by an entirely black abdomen, black matte mesonotum, dark
legs, and halteres with a brownish stem. In the key by Steyskal (1971) S. fasciolata is
close to S. angusticollis Frey, 1956 (from Burma). e last species is characterized by
the arista covered with short setulae.

Diagnosis. Species of Strongylophthalmyia are characterized by a slight shift of the
ocellar tubercle anteriorly and in some species, the ocellar tubercle can be situated in
the middle of the frons. Strongylophthalmyia gavryushini sp. n., however, has the ocel-
lar tubercle positioned nearly on the edge of the vertex. e value of frontal index (the
ratio between height of the frons from its anterior margin to hind ocelli and from hind
ocelli to vertex or vti) is high, equal to 4.3. e frontal index of the other new species
of Strongylophthalmyia described in this paper vary from 1 up to 1.7. Only S. tomentosa
sp. n. has the frontal index equal to 2.7.

Diagnosis. e new species belongs to a large and varied group of species with a
yellow postpronotum. Within this group, Strongylophthalmyia tomentosa sp. n. is close
to S. bifasciata Wang & Yang from China (Zhejiang) on the basis of a longitudinal
band running along R2+3 from its base to the medial transverse band. Strongyloph-
thalmyia dorsocentralis has a similar wing band, but this species diers from rst two
species by many characters, including the coloration of the thorax and by the absence
of microsetulae across the mesonotum. Strongylophthalmyia tomentosa sp. n. diers
from S. bifasciata by the shorter vein R2+3, smaller size of apical spot and by bare arista.
Strongylophthalmyia tomentosa sp. n. is also similar to S. annulipes sp. n. (see the diag-
nosis of S. annulipes).
Description. Female. Head slightly shorter than height. Frons matte black, nar-
rowly yellow anteriorly. e ratio between height of the frons from its anterior margin
to hind ocelli to the distance from the hind ocelli to vertex or vti is equal to 2.7. Oc-
ciput black, shining, slightly convex. Face yellow with row of short setulae along su-
ture, clypeus yellow shining; parafacial yellow with silver grey tomentum. Gena black
with small brownish spot between lateral margin of mouth and parafacial. Antenna

ner surface, narrowly yellow basally, widely dark brown apically and on dorsal margin
externally, with short yellow dorsal setulae. Arista dark brown, bare. Mouthparts dark
brown; palpus yellow, with short and thick black setulae apically. Chaetotaxy: Two
orbital setae (posterior seta 2.6 times longer than anterior seta), 1 ocellar seta, 1 posto-
cellar seta, 1 inner vertical seta, 1 outer vertical seta, frontal setae absent.
orax black. Postpronotum, proepisternum, basisternum, anepisternum around of
spiracle yellow, and yellow coloration on postpronotum slightly extending to mesono-
tum (Figure 8a,b). Mesonotum matte, sparsely covered with short pale setulae; pleuron

ince, So Pa (22.34147°N, 103.85818°E), 1490 m, 24.X.2015 (D. Gavryushin).
Diagnosis. Strongylophthalmyia splendida was described based on single female
from Tibet (China), caught at a height of 2050 m. is species is characterized by
some interesting and unique characters, including a head that is nearly 1.4 times longer
than high (which is caused mainly by lengthening of the occiput). In other Strongy-
lophthalmyia, the head is globular (approximately as high as long) and the occiput part
is short, only 0.1–0.2 times shorter than length of the eye. Furthermore, the outer
vertical seta is absent, the frontal setae are absent and only one short hair-like orbital
seta is developed. We also note yellow coloration of frons with a brown round spot
between the ocellar tubercle and the vertex.
Other interesting character of the species is the presence of a large seta situated on
the anterior part of the mesonotum near the postpronotum in front of posthumeral
line (Fig. 9b). Vein R4+5 is slightly arcuate, terminating behind the wing apex (Fig. 9a);
vein CuA2 is more or less straight; cell bm is rather long, terminating approximately
at the level of the costal break; cell bm is shorter than the discal cell by approximately
in 0.8 times.
Description of male. Head yellow, shining in black area, 1.4 times longer than
height. frons with brownish to blackish (in view from dierent angles) rounded spot not

with narrow dark brown apical ring; mid tibia with brownish stroke in basic quarter;
hind tibia darkened, yellowish basally and apically. Fore femur dorsally with row of
10 black setae. Fore femur laterally with row of long dense yellowish setulae situated
apically aside of femoral apex; basally these setulae 1.3 times longer than those occur-
ring apically. Wings greyish, without apical spot and without median transverse band.
