Tachyusa agilis Baudi, 1869 ( Figs. 18–20)

Tachyusa agilis Baudi, 1869: 376 .

Tachyusa (Caliusa) agilis: Ganglbauer, 1895: 248 ; Fenyes, 1920: 173; Bernhauer & Scheerpeltz, 1926: 586.

Type material. Lectotype (here designated): ♂: Cyprus, T. agilis Baudi (DEI) . Paralectotypes: ♂ and ♀: same data as the lectotype ( DEI) .

Additional material. Cyprus: N. Limassol, Limnatis­river near Alassa , 300 m, 8.IV.1995, V. Assing, 1 ex ( VAPC); Cyprus (localities not specified), 6 exx ( IRSNB) .

Redescription. Body. Length 2.6–2.8 mm; convex, parallel­sided, glossy; head black, pronotum and elytra brownish red, abdomen black with three basal tergites red, legs red, antennae brown with antennomeres 1–3 red.

Head circular in outline, convex; eyes 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 dense. Antennae short, clearly increasing in width apically, antennomere 3 shorter than 2, 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 without transverse impression; surface lacking microsculpture; puncturation fine, moderately dense and weakly asperate; pubescence at midline directed posteriorly.

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 very fine and scattered, punctures very fine and weakly visible, surface without microsculpture.

Male. Aedeagus as in Figs. 18–19.

Female. Spermatheca as in Fig. 20.

Remarks. Tachyusa agilis is similar to T. schuberti , but can be distinguished by the following characters: pronotal colour darker; antennae longer and less increasing in width towards the apex; pronotal puncturation denser; pronotum more convex; the shape of the aedeagus different.

Distribution. Tachyusa agilis is known so far only from Cyprus.
