tion, length, and degree of development as, 
figured; base of branched hairs, except 8-C, 
without flattened, expanded plate. Hairs:

Abdomen: Basal segments unevenly pigment- 
ed, with submedian pale areas, connected on

pigmented; tergites II-VII with small pos- 
teromedian patch of indistinct minute spic- 
ules; tergite VIII with anteromedian patch of

culations not visible; sternites III-VIII with 
extensive median patch of extremely minute 
and indistinct spicules. All hairs lightly pig- 
mented; relative position, length, and degree 
of development as figured; bases of branched

IX: hair 1(1, very thin, slightly longer than 
segment). Paddle as figured; very lightly pig-

ly pigmented; external buttress poorly defined; 
external margin with minute teeth; apex of 
inner margin with a few lighter teeth; hair 1 
absent. Genital lobe extending to about 0.27

Anal segment with dorsolateral expansion, no 
indication of cereal sclerite. Male genital lobe 
(exuviae of allotype, 932-102) extending to 
0.4 of paddle, pair of small ventral apico- 
lateral patches of weak spicules; anal segment 
extending 0.5 from apex of IX to apex of 
genital lobe, 0.5 width of latter.
