Redescription. Body. Length 2.8–3.2 mm, convex, parallel­sided, glossy; body colour pitchy brown to black; legs reddish brown, tarsi yellow, antennae brown with three basal antennomeres red.
Head circular in outline, convex; 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 fine and dense. Antennae short, clearly increased in width apically, antennomere 3 shorter than 2, antennomere 4 longer than wide, antennomeres 5–10 quadrate, antennomere 11 nearly conical.
Pronotum quadrate, lateral sides gradually narrowed in straight line to obtuse hind angles; before base with broad and shallow transverse impression; surface lacking microsculpture; puncturation fine, dense and asperate; pubescence at midline directed entirely posteriorly.
Elytra subquadrate, at suture shorter than pronotum at midline; surface without microsculpture; puncturation fine, dense and asperate.
Abdomen subparallel­sided, bases of tergites 3–5 each with transverse impression, impressions coarsely and densely punctuate; tergal puncturation fine and dense, surface lacking microsculpture.
Male. Aedeagus as in Figs. 39–40.
Female. Spermatheca as in Fig. 41.
Remarks. Ischnopoda scitula is similar to I. umbratica, but can be easily distinguished from that species by the strongly convex pronotum, the antennomere 3 shorter than 2 and by the pronotal pubescence at midline directed entirely posteriorly.
Distribution. The area of distribution of I. scitula ranges from France in the west to Hungary and Poland in the east. In the north it reaches Sweden and England.
