Ischnopodaburgeoni ( Bernhauer, 1934) comb. n. ( Figs. 71–73 )

Tachyusa (Ischnopoda) burgeoni Bernhauer, 1934: 212 .

Type material. Lectotype (here designated): ♂: Kenya, Mombassa (36 km S. Lubero), VIII.1932, L. Burgeon, R. DET. U 2555 ( MRAC) . Paralectotypes: 2♂♂: same data as the lectotype ( MRAC) ; ♂: Kenya, Mombassa (36 km S. Lubero), VIII.1932, L. Burgeon, T. burgeoni Bernh. (FMNH) .

Redescription. Body. Length 3.4–3.6 mm, convex, parallel­sided, glossy; body colour dark brown, abdominal tergites 5–7 black, legs red, antennae brown with antennomeres 1– 3 red.

Head circular in outline, convex, moderately broadly and moderately deeply impressed medially; eyes large, moderately protruding from lateral contours of head, length of each seen from above subequal to that of postocular region; surface of head with fine isodiametric mesh microsculpture; puncturation fine and dense. Antennae short, clearly increased in width apically, antennomere 3 longer than 2, antennomeres 4–10 longer than wide, antennomere 11 nearly conical.

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

Elytra transverse, at suture shorter than pronotum at midline; surface without microsculpture; puncturation fine and dense.

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

Male. Aedeagus as in Figs. 71–72 .

Female. Spermatheca as in Fig. 73 .

Remarks. Ischnopoda burgeoni is similar to I. depressa , but differs in having the pronotal surface without microsculpture; the antennomere 3 longer than 2; the head puncturation much finer, similar to that on pronotum, and by the shape of the aedeagus.

Distribution. Ischnopoda burgeoni is known only from the type locality in Kenya.
