Description 
FEMALE (523-23).— Wing: 2.66 mm. Ab- 
domen: 1.66 mm. Proboscis: 1.50 mm. Eront 
femur: 1.83 mm. 
Head: Numerous elongate dark erect vertical 
scales, stem very slender, apex expanded, 3- 
or 4-pronged; no frontal tuft; recumbent 
scales iridescent very light purplish-brown, 
lighter laterally toward apn; orbital bristles 
rather evenly spaced. Clypeus light brown. 
Palpus about 0.09 of proboscis; purplish- 
brown scales apically; hairs about 0.5 of shaft 
length. Proboscis distinctly swollen apically; 
dark-scaled dorsally, lighter ventrally, espe- 
cially on swollen part; numerous short hairs 
apically; labella light, densely hairy. Antenna 
about 1.33 of proboscis; torus light brown. 
darker mesally and dorsally, with short hairs 
mesally; base of first flagellar segment cream- 
colored, remainder of flagellum very dark 
brown; first flagellar segment 1.2 of second; 
three apical segments subequal. 
Thorax: Conspicuous velvety black spots on 
posterior pronotum and on scutum in front 
of wing root as figured. Scutal integument 
uniformly light brown; dense vestiture of 
recumbent narrow purplish-brown scales cen- 
trally; tuft of erect lighter narrow scales at 
extreme anterior end among dorsocentrals and 
a few shorter curved recumbent light scales 
just external to dorsocentrals above anterior 
end of ppn; elongate patch of narrow recum- 
bent scales over black spot in front of wing 
root, scales lighter than on disc, becoming 
whitish in caudal extension over supra-alar 
bristles; acrostichals short, ail bristles dark. 
Scutellum brown; median lobe moderate, with 
one weak and four strong bristles; lateral lobe 
with four strong and two weak bristles; vesti- 
ture of broad recumbent purplish bronzy- 
brown scales projecting moderately over bris- 
tles of lateral lobe. Pleural integument cream- 
colored, darker along diagonal line from 
spiracle to lower mesepimeron and on apn, 
velvety black spot on ppn\ scales absent except 
broad translucent whitish scales forming large 
patch on apn; large bristles dark, smaller light; 
propleurals four, upper mesepimerals three or 
four. Haltere light at base and lower part of 
stem, dark-scaled on upper part of stem and 
knob. 
Wing: Distance between crossveins 0.4 of 
m-cu. Vein R 2 about 0.29 of R 2 -f 3 ; vein M 1+2 
about 0.72 of M beyond m-cu. Wing scales 
all dark. Eringe narrow, dark. 
Legs: Coxae and trochanters cream-colored; 
scales light and translucent, inconspicuous; 
coxa I with about 12 bristles on anterior face; 
coxa III with seven bristles on caudal face. 
Femora dark-scaled above, lighter below; fe- 
mur II swollen basally, cream-colored ven- 
trally, with seven conspicuous thin erect hairs 
dorsally in basal half and three similar hairs 
on external surface of apical third. Tibiae dark
