Head circular in outline, convex, eyes relatively small, weakly protruding from lateral contours of head, length of each seen from above shorter than postocular region; surface of head without microsculpture; puncturation fine and moderately dense. Antennae short, clearly increasing in width apically, antennomere 3 shorter than 2, 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 dense and slightly asperate; pubescence at midline directed posteriorly.

Elytra longer than wide, at suture as long as pronotal length at midline; surface lacking microsculpture; puncturation fine, moderately dense and weakly asperate.

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

Male. Aedeagus as in Figs. 15–16.

Female. Spermatheca as in Fig. 17.

Remarks. From the other Palaearctic species, Tachyusa constricta can be easy distinguished by the very slender body, the strongly narrowed temples; the small and strongly convex pronotum, the very strongly constricted abdomen, and by the very elongate tergite 3.

Distribution. Tachyusa constricta is widespread in the Palaearctic Region, from France and Italy in the west to the Altai Mts. in the east.
