Head, thorax, legs, costal margin at base, and anal segment of 
female yellowish orange, heavily powdered white in life; tegmina 
pale, with round black spots, chiefly in basal half. 
Anal segment of male rather short, apical margin truncate or 
shallowly indented at middle, apical angles rounded, anus situated at 
basal third, segment in profile very slightly decurved. Pygofer 
broad, lateral margins slightly curved, ventral margin sinuate, in- 
dented medially. Aedeagus with periandrium tubular, deeply cleft 
laterally at apex, median ventral process narrowing distally and 
passing into a sclerotized point, dorsal margin broad, truncate at 
apex; penis tubular, bifid in apical half, each limb curved upward 
distally into a spine, half as long as aedeagus, directed anteriorly 
above periandrium. Genital styles broad, expanding gradually api- 
cally, apical margin oblique, apical process a vertical spine, slightly 
curved anteriorly. 
Anal segment of female large, broader than long, slightly tectiform, 
broadly rounded at margin, anus situated two-thirds from base. Ovi- 
positor with lateral styles broad, thick, with a single even line of nine 
teeth on posterior margin directed mesad; second valvulae apposed 
medially, semimembranous, ventral margin very slightly convex, dor-
