of scutum dark brown, densely clothed with fine dark bronzy-brown scales, 

 except for a silvery-white to pale-yellow scaled median longitudinal stripe

 scutum) . Dorsal half of posterior pronotum covered with narrow dark brown 

 scales. Abdomen: Tergites dark scaled, with conspicuous basal triangular 

 patches of white scales laterally; venter primarily whitish scaled, often speckled 

 with dark scales. Legs: Legs dark scaled except for pale inner surfaces of

 usually more prevalent on occiput. TERMINALIA. (Fig. 88A). Lobes of ninth 

 tergite (IXT-L) about as long as broad, separated by a little less than the 

 width of one lobe, each bearing several short spines. Tenth sternite (X-S) 

 prominent, heavily sclerotized beyond middle. Phallosome (Ph) stoutly coni- 

 cal, rounded apically, open ventrally, closed dorsally. Claspette stem (CI-S) 

 pilose, large, stout, sinuous, broader medially, constricted basally and apically, 

 extending a little beyond middle of basistyle; claspette filament (Cl-F) about 

 one- third as long as stem but much narrower than expanded middle portion 

 of stem, striated, curved and tapered at apical third. Basistyle (Bs) about three 

 times as long as width across middle, narrower distally, rounded at apex.
