Redescription. Body. Length 2.5–3.2 mm; convex, parallel­sided, glossy; head, pronotum and elytra pitchy brown to black, abdomen black with two basal tergites reddish yellow, legs testaceous, antennae brown with antennomeres 1–3 red.

Head subquadrate 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 moderately dense. Antennae short, clearly increasing in width apically, antennomeres 2 and 3 subequal in length, antennomeres 4–8 longer than wide, antennomeres 9–10 sexually dimorphic, quadrate in male and slightly transverse in female, antennomere 11 nearly conical.

Pronotum quadrate, lateral sides gradually narrowed in straight line to obtuse hind angles; before base with small and shallow transverse impression; surface without microsculpture; puncturation fine, moderately scattered and weakly asperate; pubescence at midline directed posteriorly in apical half and anteriorly in basal half.

Elytra subquadrate, at suture as long as pronotal length at midline; surface lacking microsculpture; puncturation fine, moderately dense and slightly asperate.

Abdomen parallel­sided, bases of tergites 3–5 each with deep transverse impression, impressions with 7–8 longitudinal ridges, tergal puncturation fine and very scattered, punctures very small and scarcely visible, surface without microsculpture.

Male. Aedeagus as in Figs. 26–27.

Female. Spermatheca as in Fig. 28.

Remarks. Tachyusa balteata is similar to T. ferialis Erichson, 1839 , from which it can be easy distinguished by the black pronotum (red in T. ferialis ), the larger eyes, the stouter body, the more distinct and denser pronotal puncturation and by the shape of the genitalia.

Distribution. T. balteata is widespread in Europe (except north) and North Africa.
