well developed. Supraalar area of mesonotum 
with several broad, apically rounded or trun-

base of abdomen middorsally; trumpet very 
dark brown, lighter apically; integumentary 
abdominal sculpturing distinct only on darker 
areas. Trumpet index about 2.3; width at 
basal 0.1 about 0.25 of that at middle; pinna 
about 0.39. Hairs 5-IV-VI(l); 2-II-VII(l); 
l-II(simply branched); l-IV-VI(l-3b). Pad-

hairs single or with at most 6 or 7 short 
branches; large single hairs swollen and 
fringed near base. Thoracic hairs: 1-P(3b, 
longer than 3-P); 2-P(l, about as long as 
1-P); 3-P(3, 4b, apices attenuate); 5-P(l, over
