Thorax: Scutal integument rather uniformly 
brown; moderately dense vestiture of recum- 
bent narrow elongate golden-brown scales, 
becoming broader and denser in prescutellar 
space; line of white scales extending from 
wing root to wing root around the lower mar- 
gin in front as figured, integument brown; 
white scales in patch on anterior acrostichal 
area small and narrow; white scales in lateral 
portion of line small and narrow at anterior 
end becoming longer and broader posteriorly, 
not forming a distinct tuft in front of wing 
root; acrostichal bristles moderate, dorsocen- 
trals very strong, others strong, all dark. Scu- 
tellum dark brown; median lobe moderate, 
with two strong bristles, scales small, golden 
brown, projecting slightly over base of bris- 
tles; lateral lobe with two strong bristles, 
scales elongate, projecting strongly over base 
of bristles. Pleural integument uniformly dark 
brown except for light iridescent areas in line 
with white-scaling; scaling and chaetotaxy as 
figured; scales white; median patches on apn 
and stp in line with white-scaling of head; 
scales of apn broad anteriorly, more elongate 
posteriorly and forming a small projecting 
tuft; scales of transverse patch of stp in two 
or three rows, individual scales oval, decum- 
bent; scales of lower sternopleuron scattered, 
translucent dark, broadly oval; bristles dark, 
propleurals strong, spiracular and upper me- 
sepimerals absent. Haltere light on base and 
stem, knob cream-scaled basally, dark-scaled 
on extreme apex. 
Wing: Distance between cross veins about 1.3 
of m-cu. Vein R2 about 0.33 of R2+3; vein 
Mi +2 about 0.6 of M beyond m-cu. Conspicu- 
ous black and white pattern of scaling on 
dorsal and ventral surfaces: anterior border 
dark, median and posterior part white, with 
indistinct gray subapical transverse band, apex 
of wing white beyond base of anterior fork 
cell (R2) ; vein C dark except on caudal margin 
at base and at apex beyond level of cell R2; 
vein Sc dark-scaled ventrally; vein R white 
at base to 0.24 of wing length; veins Rs and 
R2-f3 dark-scaled below and above; vein R4-1-5 
dark-scaled above at extreme base, then for 
one third its length starting at 0.17, white- 
scaled for remainder of dorsal surface and 
entire ventral surface; vein M dark-scaled ven- 
trally from m-cu distad; veins M1+2 and M3 
dark-scaled at base dorsally; vein Cui dark- 
scaled for its apical 0.65, Cu2 for its entire 
length; remaining portions of all veins white- 
scaled. Fringe white, creamy at apex. 
Legs: Coxae and trochanters brown to light 
brown; scales translucent except proximally 
on coxae I and II where they are white. Fem- 
ora dark above, cream-colored below; prom- 
inent dorsal knee spots of pure white scales. 
Tibiae dark-scaled, cream-colored apically. 
First two segments of tarsi dark-scaled, lighter 
below; basal third of segment 3 dark above; 
remainder of segment 3 and all of segments 
4 and 5 white-scaled, pure white on tarsus 
III, cream-white on I and II. Leg I: femur 1; 
tibia 1.0; tarsus 0.80, 0.45, 0.30, 0.15, 0.10. 
Leg II: femur I.06; tibia 1.40; tarsus 0.88, 
0.42, 0.30, 0.12, 0.05. Leg III: femur 1.10; 
tibia 1.20; tarsus 0.98, 0.60, 0.47, 0.25, 0.06. 
Abdomen: Tergite 1 white-scaled except for 
cream-colored patch laterally; tergites 2-4 
with large median patch of white scales ex- 
tending from base to apex, wider apically; 
tergite 5 with white-scaled patch occupying 
apical two thirds; tergites 6 and 7 with median 
apical transverse band of white scales; re- 
mainder dark-scaled, Sternites dark-scaled. 
MALE (932-102). —Wing: 1.54mm. Probos- 
cis: 1.05 mm. Front femur: 1.33 mm. 
Generally very similar to female. Proboscis 
more distinctly swollen apically. Orbital line 
of white scales much narrower than in female. 
Flagellar whorls about 0.4 of flagellum, with 
about 26 bristles; penultimate segment about 
1.65 of preceding, apical about 1.10 of penul- 
timate. Leg I: femur 1; tibia 1.0; tarsus 0.75, 
0.45, 0.27, 0.13, 0.07; claws equal, one broad- 
ened, other slender. Leg II: femur 1.05; tibia 
1.41; tarsus 0.88, 0,46, 0.26, 0.12, 0.08, seg- 
ment 4 with median ventral lobe projecting 
below 5, segment 5 with dorsoapical lateral 
lobes; claws enlarged, smaller claw 0.65 of
