Taxonomic notes
. An examination of the
types
listed above, particularly the genitalia, revealed that they are all conspecific. Therefore,
Ischnopoda egregia
Pace
is here synonymised with
Tachyusa madecassa
Cameron
, the oldest name available.

Head circular in outline, convex; eyes large, strongly protruding from lateral contours of head, length of each seen from above longer than postocular region; surface of head without microsculpture; puncturation minute, pinpricklike and moderately dense. Antennae moderately long, extending to base of pronotum, slightly increasing in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–8 longer than wide, antennomeres 9–10 as long as wide, antennomere 11 nearly coniform.
Pronotum quadrate, convex, lateral sides sinuately narrowed to obtuse hind angles; before base with relatively large transverse impression; surface without microsculpture; puncturation fine and moderately dense; pubescence at midline directed posteriorly in apical half and anteriorly in basal half.
Elytra subquadrate, at suture as long as pronotal length at midline; surface without microsculpture; puncturation minute, pinpricklike and moderately sparse.
Abdomen widened posteriorly, bases of tergites III–V each with deep transverse impression, first two impressions coarsely punctate, third impression smooth, impunctate; tergal puncturation minute, pinpricklike and sparse; surface without microsculpture.
