dorsum with narrow golden scales, dark up- 
right-forked scales posteriorly and pale ones 
anteriorly; lateral portion of vertex with broad 
pale scales. Thorax: Scutum brown, rather 
thinly covered with hair-like brownish-gold 
scales, paler over wing bases, and on pre- 
scutellar area. All scutellar lobes with narrow 
yellow scales. Apn with broadened and mar- 
row yellow scales; ppn with narrow yellow 
scales. Each of the following pleural areas 
with a patch of broadened whitish scales: 
subspiracular, dorsal sternopleural, ventro- 
posterior sternopleural, and mesepimeral (pin 
through postspiracular area). Legs: Fore and 
mid-femora dark anteriorly, some scattered 
pale scales ventrally, and pale scales at apices; 
hind femur pale-scaled anteriorly except for 
a dark apical area, dark scales on dorsal sur- 
face, a ring of pale scales on extreme apex 
anteriorly. Tibiae dark. Fore tarsi dark except 
for a few pale scales basally on II; mid-tarsi 
with narrow basal pale bands on I-II; hind 
tarsi with narrow basal pale bands on I-V, 
broadest on I and narrower on each succeed- 
ing segment. Fore and mid-tarsal claws un- 
equal, each unidentate; hind tarsal claws equal, 
each unidentate. Wings: Dark-scaled, wing

Drawing and description from a New Guinea 
specimen. Basistyle short, broad; a prominent 
subbasal lobe present, this bearing numerous 
very stout setae. Dististyle broad, deeply di- 
vided apically into a pair of unequal arms, the 
shorter of these bearing several setae. Ninth 
tergite broadly divided medially. 
Female. Similar to the male but differing as 
follows. Palpus approximately one-fifth as 
long as proboscis, dark. Torus with a few dark 
hairs and scales medially. Vertex with a medio- 
anterior area of dark narrow scales and with 
a patch of broad dark scales at lateral margin 
of dorsal narrow-scaled area. Scutum with a
