Nepalomyia reunionensis
sp. nov.
(
Figs. 24−26
)
Diagnosis.
Nepalomyia reunionensis
is close to
N. kotrbae
sp. n.
, differing in simple fore tarsus and in hypopygium morphology. The new species is related to the
pallipes-
species group (
Wang et al. 2007
), differing from Oriental species in bearing posterodorsal row of 5-6 dark setae on hind tibia.

Description. Male:
Similar to
N. kotrbae
sp. nov.
in all respects except as noted:
Head
: Face under antennae about as wide as height of postpedicel, slightly narrowing towards clypeus. Antenna black; postpedicel subtriangular, slightly higher than long.
Thorax
: Mesonotum weakly shining.
Legs
: Yellow-brown with coxae and 5th tarsomeres brown. Fore leg without strong setae and remarkable cilia; length ratio of fore tibia to tarsus (segments from first to fifth):
27/ 14/6
/6/5/5. Mid tibia with 1 anterodorsal and 1 posterodorsal seta at basal fourth, 1 anterodorsal at 2/3. Length ratio of mid tibia to tarsus (segments from first to fifth):
39/17/9
/7/5/5.
Hind
tibia with 2 anterodorsals, posterodorsal row of 5−6 dark setae and with simple subapical dorsal bristle. Length ratio of hind tibia to tarsus (segments from first to fifth):
47/9/14
/9/6/6.
Wing
: Greyish, veins brownish. Ratio of part of costa between R2+3 and R4+5 to that between R4+5 and M1+2: 13/10. Ratio of dm-cu to apical part of CuA1: 10/23.
Abdomen
: Brown, cylindrical, as long as thorax, with black hairs and marginal setae; tergum 6 small, glabrous; sterna 5 and 6 weakly sclerotized. Segment 7 glabrous, reduced, with small sternum; segment 8 brown, large, rounded, setose; hypopygium brown, with yellow cercus; epandrium ovoid, longer than high, concave ventrally in distal half; foramen lateral, positioned in basal half of epandrium; hypandrium not fused with epandrium, originating from 2 basolateral arms, then simple, short, nearly parallel-sided, with cut apex; phallus thickened at base, slender, cleft at apex; epandrial lobes reduced to 3 simple epandrial setae, with 2 setae long, and small lobe at distoventral corner of epandrium bearing short seta; surstylus symmetrical, reduced, bilobate, with dorsal arm broad, with 2 dorsal setae; ventral arm of surstylus narrow, almost bare; cercus elongate-ovate, flat, with strong marginal and short sparse dorsal setae.
Measurements
(mm): Body length 1.1–1.3, antenna length 0.45, wing length 1.5, wing width 0.5, hypopygium length 0.33.
Female
: Similar to female
N. kotrbae
sp. nov.
Similar to male except lacking male secondary sexual characters. Each hemitergite with 4 thick setae.
