beyond the middle that has a dorsal extension 
nearly to the apex (this area variable); hind 
femur pale-scaled, marked anteriorly and 
posteriorly with a basal and a subapical dark 
area. Fore tibia with posterior surface pale 
except for extreme apex, this pale scaling ex- 
tending onto the anterior surface apically; 
mid tibia dark except for an apical pale area 
(some dark scales present on the extreme 
apex, however); hind tibia dark. Fore tarsus 
dark; mid tarsus with a broad basal band and 
an incomplete apical white band on I, a 
dorso-basal spot on II; hind tarsus with in- 
complete dorso-basal and apical white bands 
on I, a narrow incomplete basal band on II, 
III-V dark. Fore and mid tarsal claws unequal, 
the larger bidentate, the smaller unidentate; 
hind claws equal, simple. Wings: Dark- 
scaled, may be a few pale scales at the base of 
the costa. Halter knob dark-scaled. Abdomen: 
Fig. 5. A. {Finlay a) melanopterus. Male terminalia 
(Luzon). 
Tergites I, VI, and VII with lateral white 
bands; II-III with a baso-lateral white area 
(sometimes forming a nearly complete basal 
band on III), IV-VII with narrow basal white 
bands, IV-VII with the median dark scales 
somewhat erected. Sternites dark-scaled, a 
basal patch of white scales present on most 
of them; III-VII with prominent medial tufts 
of dark elongate erected scales. Terminalia: 
Basistyle without lobes, a prominent patch of 
setae on basal half of mesal-tergal surface and 
another medially on mesal-sternal surface. 
Mesosome simple, slightly expanded apically. 
Claspette filament expanded subapically in 
lateral view. Lobes of ninth tergite inter- 
rupted. 
The male from Palawan had the transverse 
dark scutal band broadly interrupted medially. 
Female. Wing length about 3.5 mm. Differs 
from male mainly as follows: Palpus ap- 
proximately one-fifth as long as the pro- 
boscis. Torus with fine dusky hair-like scales 
medially. Vertex dorsum with broad dark 
scales (may be a very few pale ones medially), 
a patch of narrow pale scales anteriorly on the 
median line and some also on the nape, a line 
of pale scales along the eyes, and scattered 
dark upright-forked scales; lateral area with 
broad white scales. Scutum with narrow 
scales, dark except for a large anterior area of 
white scales, a white area before the wing 
base, and before and along the prescutellar 
area. Scutellar mid lobe with narrow pale 
scales, narrow dark scales intermixed later- 
ally; lateral lobe with a few narrow pale scales. 
Tarsal claws equal, fore and mid each uni- 
dentate, hind simple. Tergites dark, IV-VII 
with a small baso-median white spot, VIII 
with a broad basal white band, lateral aspect 
marked as in male. 
LARVA. Head: Antenna smooth; antennal 
hair single, inserted at apical one-third. 
Mouth brush with comb-like tips. Preclypeal 
spine single, stout. Hair 4 with 4-7 branches,

2-3; 9 with 2-4; 12 with 4-7; 13 with 1-2;
