The genus Thinodromus in West-Central Africa ( Coleoptera) 53 Thinodromus nigerius GlLDENKOV, 2000 (Figs 40, 47-49, 55-56) Studied material - "Nigeria: Ile-Ife, W State, [07°28' N, 04°34' E], 15 Jul 1970, col. J. T. Medler, Coll. Mus. Tervuren" (1 male, MRAC); "Coll. Mus. Tervuren, Côte d'Ivoire: [Departement de Divo,] Divo [05°50' N, 05°22' W], J. Decelle, 28.XI.1963" (1 male, MRAC). Description - Measurements (in mm, n = 2): HW = 0.51 (0.50-0.52); TW = 0.46 (0.45-0.46); PW = 0.58 (0.57-0.58); SW = 0.70 (0.70-0.70); AW = 0.79 (0.78-0.80); HL = 0.31 (0.30-0.32); EL = 0.20 (0.20-0.20); TL = 0.03 (0.02-0.03); PL = 0.42 (0.42-0.42); SL = 0.67 (0.66-0.68); SC = 0.58 (0.58-0.58); BL = 2.70 (2.60-2.80); FL = 1.41 (1.40-1.42) mm. - Colour. Moderately shiny, head rather dull (traces of microsculpture?). Body dark brown (blackish with reddish tint), forebody appears a tad lighter than abdomen, legs and antennae medium to dark brown, supraantennal tubercles and first antennomeres also somewhat lighter. - Shape and sculpture. Head rather transverse, temples very short, not conspicuous, eyes almost fully occupy sides of head. Antenna! segments ovoid, antennomeres 4-5 1.40-1.60X longer than broad, antennomeres 9-10 1.00-l.l4x broader than long. Pronotum also transverse, pronotal side before hind angles very gently concave. Horseshoe-shaped impression posteriorly rather deep, its side branches reach till the anterior edge of pronotum in the form of shallowly depressed areas. Disc in the middle with gentle dual impressions. Reflexed lateral margin thin, not very conspicuous, only apparent in the posterior half of pronotal side and on posterior edge. Elytra together broader than long (1.25x), gently dilating towards apex, with a shallow impression behind shoulders in the anterior third of disc (anterior to it there may be a small elevated area; behind scutellum impression with microsculpture). - Punctation and microsculpture. Head punctation medium fine but very dense, almost no significant interspaces (therefore appears more dull than other body parts). Pronotal punctation also medium fine, interspaces 1 /2-3/4 of puncture diameters. Elytral punctation very similar to that of pronotum, but posteriorly with more coarse punctures. Abdominal punctation rather coarse (posteriorly increasing) with larger interspaces (at least 1 /2-3/4 of puncture diameters), therefore it appears the most shiny of the main body parts. Microsculpture on the body only in traces on the head (not clearly visible for its dense punctation) and in posterior pronotal corners, where punctation diminishes into coriaceous ground sculpture. - Pubescence. Setation semierect, uni-sized. Rather short and uniform on elytra and head, a little longer and unequal on pronotum, on abdomen with rather long hairs on posterior edges of terga. - Primary and secondary sexual features. Male: the inner sac of the aedeagus (Figs 47-49) has similar development to that in T. kedougouensis, sternite VIII (Fig. 55), tergite X (Fig. 56). Comparative notes - T. nigerius GILDENKOV, 2000 is rather similar to T. capensis BERNHAUER, 1934, described from South Africa. Bionomics - The holotype of T. nigerius was collected at light.
