Ischnopodasubaenea Eppelsheim, 1890: 164 .

Type material. Lectotype (here designated): ♀: Kaukaz [Caucasus], Leder , 119 ( subaenea Epp. Wien ent. Zeit. 1890 p. 164) Collect. Eppelsh. ( NMW) . Paralectotypes: ♀: Kaukaz , Leder, Michailowo am Suramgebirg, Collect. Eppelsh. ( NMW) ; ♂: Kaukaz , Leder , Au 7., Kura bei Borshom ( NMW) .

Redescription. Body. Length 3.2–3.5 mm, convex, parallel­sided, glossy; body colour brown to pitch brown; elytra reddish­brown with yellow posterior margin, legs testaceous, antennae brown with antennomeres 1–3 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, 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 gradually narrowed in straight line to obtuse hind angles; before base with moderately small and shallow transverse impression; surface without microsculpture; puncturation fine, moderately dense and asperate; pubescence at midline directed entirely anteriorly.

Elytra subquadrate, at suture as long as pronotum at midline; surface without microsculpture; puncturation fine, dense and asperate.

Abdomen parallel­sided, bases of tergites 3–5 each with deep transverse impression, impressions coarsely and densely punctuate, tergal puncturation uniformly fine and dense, tergite 8 with obsolete transversely stretched isodiametric mesh microsculpture.

Male. Aedeagus as in Figs. 25–26 .

Female. Spermatheca as in Fig. 27 .

Remarks. Ischnopoda subaenea is similar to I. umbratica , from which it differs by the pronotal surface lacking microsculpture, the paler elytra, the sparser and less asperate pronotal and elytral puncturation and by the shape of aedeagus.

Distribution. The species is known only from Caucasus region.
