Redescription. Body. Length 3.5–3.6 mm, convex, parallel­sided, glossy; body colour testaceous, head brown, abdominal tergites 6–7 black, legs red, antennae brown with antennomeres 1–3 yellow.

Head circular in outline, convex, broadly and shallowly impressed medially in male and without impressions in female; eyes large, moderately protruding from lateral contours of head, length of each seen from above subequal to that of postocular region; surface of head without microsculpture; puncturation relatively coarse and dense. Antennae long, clearly increased in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–7 longer than wide, antennomeres 8–10 quadrate, antennomere 11 nearly conical.

Pronotum quadrate, lateral sides concavely narrowed to obtuse hind angles; before base with moderately small and shallow transverse impression, broadly and shallowly impressed medially in male and without impression in female; surface without microsculpture; puncturation relatively coarse and dense; pubescence at midline directed entirely anteriorly.

Elytra transverse, at suture as long as pronotum at midline; surface without microsculpture; puncturation very fine and dense, much finer than that on pronotum.

Abdomen parallel­sided, bases of tergites 3–5 each with deep transverse impression, impressions coarsely and densely punctuate, tergal puncturation fine and dense; surface without microsculpture.

Male. Aedeagus as in Figs. 102–103 .

Female. Spermatheca as in Fig. 104 .

Taxonomic notes. An examination of the types listed above, particularly their genitalia, revealed that all the types are conspecific. Therefore, Amanota purpurascens Tottenham and Amanota wittei Cameron are here synonymized with Ischnopoda rudicollis Bernhauer , the oldest name available.

Remarks. See under I. abyssina .

Distribution. Ischnopoda rudicollis is known from Burundi, Rwanda, Tanzania and Democratic Republic of the Congo.
