Redescription.
Body. Length 2.2–2.7 mm, convex, parallelsided, glossy; body colour brown; legs yellow, antennae red, antennomeres 1–3 yellow.
Head circular in outline, convex, in males broadly and moderately deeply impressed medially, in females without impression; 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 relatively coarse and dense. Antennae long, 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.
FIGURES 99–101.
Ischnopoda abyssina
(Bernhauer)
: 99—aedeagus in lateral view, 100— aedeagus in ventral view, 101—spermatheca.
Pronotum quadrate, lateral sides concavely narrowed to obtuse hind angles; before base with moderately narrow and deep transverse impression, broadly impressed medially in male and not or very shallowly impressed in female; surface lacking microsculpture; puncturation relatively coarse, dense, subconfluent and asperate; pubescence at midline directed entirely anteriorly.
Elytra transverse, at suture as long as pronotum at midline; surface without microsculpture; puncturation very fine, pinpricklike and scattered.
Abdomen parallelsided, bases of tergites 3–5 each with deep transverse impression, impressions coarsely and densely punctuate; tergal puncturation fine and moderately dense; surface without microsculpture.
Male. Aedeagus as in
Figs. 99–100
.
Female. Spermatheca as in
Fig. 101
.
Remarks.
Ischnopoda abyssina
is very similar to
I. rudicollis
from which it can be distinguished by its smaller size, the darker coloured pronotum and elytra, dark brown to pitchy brown, the denser elytral puncturation and by the shape of aedeagus.
Distribution.
Ischnopoda abyssina
is known from several localities in
Ethiopia
.
