Tachyusa (Ischnopoda) pratensis: Fenyes, 1920: 171 ; Bernhauer & Scheerpeltz, 1926: 583.

Type material. Holotype: ♂: Tanzania, Afrique or. Allemande , Kilimandjaro (zone des prairies), I–IV.1904, 3500 m, Ch. Alluaud, pratensis Fvl. (IRSNB) .

Redescription. Body. Length 3.1 mm, convex, parallel­sided, glossy; body colour dark brown; elytra brownish red, legs red, antennae brown with antennomeres 1–3 red.

Head transverse, flattened dorsally, broadly and shallowly 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 isodiametric mesh microsculpture; puncturation fine and dense. Antennae short, clearly increased in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–8 longer than wide, antennomeres 9–10 quadrate, antennomere 11 nearly conical.

Pronotum transverse, lateral sides concavely narrowed to obtuse hind angles; before base with moderately small and shallow transverse impression; surface without microsculpture; puncturation fine and very dense, pubescence at midline directed entirely anteriorly.

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

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. 67–68 .

Female unknown.

Remarks. Ischnopoda pratensis is closely related to I. pretiosa from which it can be distinguished by the head narrowly impressed medially, the surface of head with fine isodiametric mesh microsculpture, the antennomere 3 longer than 2 and by the shape of the aedeagus.

Distribution. The species is known so far only from the type locality.
