DESCRIPTION: Length 1.60-1.65 mm. Winged. Body dark brown with elytra red, antennae reddish, legs yellowish and palpi yellow.

Head slightly longer (0. 300 mm) than wide (0.285-0.290 mm), frontal rostrum 0.135-0.14 mm wide and 0.080 mm long. Eyes well developed (24-26 facets). Apical segment of maxillary palpi 0.185 mm long and 0.085 mm wide.

Pronotum wider (0.345-0.350 mm) than long (0.300- 0.310 mm) with lateral antebasal foveae in shallow impressions.

Elytra wider (0.595-0. 600 mm) than long (0.500- 0.525 mm) with humeri slightly protruding. Discal fovea joined to discal stria, latter reaching about elytral midlength.

Abdomen with first tergite 0.185-0.190 mm long, basal impression extending on more than third of tergal width.

Male: Antennae (Fig. 4) 0.760-0.775 mm long, club 0.290 mm long; scape and antennomeres II-III distinctly longer than wide; IV and V slightly longer than wide; VI, VII and VIII wider than long. All femora and tibiae slightly thickened, posterior margin of mesotrochanters extended into long and sharp median spines. Mesotibiae unarmed, metatibiae each with small apical spurs. Aedeagus (Figs 15-16) 0.360-0.365 mm long.

Female: Antennae (Fig. 5) 0.725–0.740 mm long, club 0.285-0.290 mm long, similar to that of male, but only slightly shorter and thinner. Genital plate as in Fig. 24.

COMMENTS: Tychus nothus sp. n. is very similar to T. olor Sabella & Kurbatov, 2002 , from which it is distinguished by its bigger size (1.55-1.65 mm T. nothus , 1.45- 1.55 mm T. olor ), by the shape of the antennomeres IV and V slightly longer than wide (wider than long in T. olor ), and by the shorter aedeagus (0.360-0.365 mm in T. nothus , 0.385-0.390 mm in T. olor ) with shorter dorsal apophysis bearing a thinner and longer dorsal process in T. nothus sp. n.
