Fig. 3. Tripteroides (M.) melanesiensis Belkin n. sp., 
typical race. Male genitalia. Espiritu Santo, New He- 
brides, tree hole (K-759). 
Wing: Scales all dark. Outstanding vein scales 
all long and narrow, confined on dorsal sur- 
face to Rs, R2+3, R2, R3, and to restricted 
portion of M basad and distad of crossveins, 
base of Mi+ 2 and M 3 + 4 and apex of lA. 
Distance between crossveins about 3.0 of 
m-cu; vein R 3 about 2.6 of R2+3; vein M 3 + 4 
about 1.33 of M distad of m-cu; base of cell 
R 2 slightly closer to wing base than that of 
cell M 2 . 
Legs: Coxae and trochanters with patches of 
white scales similar to those on pleura; femora 
dark-scaled above, light-scaled below; tibiae 
and tarsi entirely dark-scaled, lighter below. 
Leg I: femur 1; tibia 1.07; tarsus 0.64; 0.31, 
0.21, 0.11, 0.10; claws normal, equal. Leg II: 
femur 0.89; tibia 0.96; tarsus 0.69, 0.36, 0.23, 
0.10, 0.09; claws normal, equal. Leg III:

femur 0.82; tibia 0.86; tarsus 1.00, 0.68, 0.50, 
0.32, 0.14; claws small, equal. 
Abdomen: Tergites 2 to 6 with narrow apical 
transverse light-scaled bands, broader laterally 
and often interrupted mesally; remainder of 
tergites with iridescent dark scales; sternites 
light-scaled. 
male (K-759a).— Wing: 3.00 mm. Pro- 
boscis: 2.70 mm. Front femur: 2.00 mm. 
Generally very similar to female. Abdom- 
inal apical light bands more extensive than in 
female and involving tergite 7; sternite 8 
dark-scaled. Palpus about 0.8 of proboscis; 
apex with 3 moderately long bristles; segment 
5 exclusive of terminal bristles 1; segment 4 
about 1.18; segments 3 and 2 indistinctly 
separated and not articulated, about 1.45 and 
1.25; segment 1 and palpifer about 0.47. An- 
tenna about 0.66 of proboscis; longest flagel- 
lar whorls about 0.45 of flagellum; about 30 
bristles in whorl; penultimate segment about 
4.5 of preceding; apical about 0.85 of penul- 
timate, with whorl of 8 shorter bristles. Leg I: 
femur 1; tibia 1.0; tarsus 0.65, 0.33, 0.23, 
0.05, 0.08; claws unequal; shorter claw 
slender; heavier claw with small tooth slightly 
beyond middle. Leg II: femur 0.88; tibia 0.98; 
tarsus 0.78, 0.40, 0.26, 0.06, 0.08; claws as on 
fore leg but without tooth. Leg III: femur 
0.85; tibia 0.88; tarsus 1.10, 0.70, 0.53, 0.30, 
0.12; claws equal, minute. 
male genitalia (K-759c).— As in Figure 
3. Ninth tergite long laterally, rather uni- 
formly and shallowly emarginate proximally 
on dorsal surface; apex deeply emarginate 
and with pair of prominent lobes; apical 
emargination slightly narrower than width of 
lateral lobe and about as deep as wide; lateral 
lobe slightly wider than long and with 4 or 
5 long bristles, 3 of which are broadened and 
flattened before apex; a conspicuous apical 
ventrolateral sclerotization. Proctiger with 
heavy ventrolateral sclerotization ending in 
1 to 3 dorsal teeth; a patch of microsetae 
laterally and subapically. Sidepiece with min- 
ute cuticular spicules and with long and short
