FIGS 17-18 Tychus assingi , holotype , aedeagus in ventral (17) and lateral (18) views. Scale bar 0.1 mm . DESCRIPTION: Length 1.45 mm . Apterous with fused elytra. Body dark brown with abdomen darker, antennae reddish, legs yellowish and palpi yellow in male; uniformly yellowish brown with palpi yellow in female. Head sligthly wider ( 0.265-0.290 mm ) than long ( 0.255-0.275 mm ), frontal rostrum 0.165-0.175 mm wide and 0.070 long. Apical segment of maxillary palpi 0.190 mm long and 0.070 mm wide. Pronotum wider ( 0.310 mm ) than long (0.290-0. 300 mm ) with lateral antebasal foveae in shallow impressions. Elytra wider ( 0.575-0.590 mm ) than long ( 0.475-0.490 mm ) with humeri not very protruding. Discal fovea joined to discal stria, latter reaching elytral mid-length. Abdomen with first tergite 0. 200 mm long, basal impression extending on more than 1/3 of tergal width. Male : Antennae (Fig. 7) 0. 800 mm long, club 0. 300 mm long; scape distinctly longer than wide; antennomere II longer than wide, III slightly longer than wide; IV FIGS 19-20 Tychus moecha , holotype , aedeagus in ventral (19) and lateral (20) views. Scale bar 0.1 mm . wider than long, V longer than wide and slightly wider than IV, VI distinctly wider than long, VII and VIII slightly wider than previous, and markedly wider than long, VII longer than VI. Eyes large (18 facets). Posterior margin of mesotrochanters extended into small median spines, mesotibiae each with small subapical spurs, metatibiae unarmed. Aedeagus (Figs 19-20) 0.370 mm long. Female : Antennae (Fig. 8) 0.775 mm long, club 0. 300 mm long, similar to that of male but slightly shorter and thinner. Eyes small (12 facets). Genital plate as in Fig. 25. FIGS 21-22 Tychus sellarius , holotype , aedeagus in ventral (21) and lateral (22) views. Scale bar 0.1 mm . COMMENTS: Tychus moecha sp. n. is similar to T. grassator Sabella, 2011 , from which it distinguished by the shape of the antennomeres IV and VII wider than long (distinctly longer than wide in T. grassator ), by the shape of ventral portion of the aedeagal median lobe and by the different shape of the genital plate (Figs 25, 31).
