Redescription. Body. Length 2.7–2.9 mm, convex, parallel­sided, glossy; body colour black; elytra dark brown, antennae and legs brown.
Head circular in outline, convex; eyes large, moderately protruding from lateral contours of head, length of each seen from above longer than postocular region; surface of head without microsculpture; puncturation fine and moderately sparse, finer and sparser than that on pronotum. Antennae very long, extending to 3/4 of elytra, slightly increasing in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–10 longer than wide, decreasing in length, 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 relatively coarse and dense; pubescence at midline directed posteriorly in apical half and anteriorly in basal half.
Elytra subquadrate, at suture slightly shorter than pronotal length at midline; surface without microsculpture; puncturation minute, pinprick­like and 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.
Male. Aedeagus as in Figs. 72–73.
Female. Spermatheca as in Fig. 74.
Remarks. Ischnopoderona namibensis is very similar to I. intermedia, from which it can be distinguished by its larger size, the antennomeres 2 and 3 subequal in length (antennomere 3 longer than 2 in I. intermedia) and by the shape of the aedeagus.
Distribution. Namibia, Republic of South Africa, Zambia, Zimbabwe (Map 4).

Description. Body. Length 2.5 mm, convex, parallel­sided, glossy; body colour pitchy brown; elytra brownish­red, abdomen black with tergites III–IV brown, antennae brown, legs yellow.
Head circular in outline, convex; eyes large, moderately protruding from lateral contours of head, length of each seen from above longer than postocular region; surface of head without microsculpture; puncturation fine and moderately sparse, finer than that on pronotum. Antennae very long, extending to 3/4 of elytra, slightly increasing in width apically, antennomere 3 longer than 2, antennomeres 4–10 longer than wide, decreasing in length, antennomere 11 nearly coniform.

Female unknown.
Remarks. See remarks under I. namibensis.
Etymology. The name intermedia refers to the characters intermediate between I. madecassa and I. namibensis.
Distribution. Ethiopia (Map 6).
