Makranczy, Gy.: The genus Thinodromus Kraatz, 1857 in West-Central Africa (Coleoptera, Staphylinidae: Oxytelinae)

The genus Thinodromus in West-Central Africa ( Coleoptera) 57 Pronotal base mostly have the finer type hairs, just like the head, while pronotal sides mostly have the long ones. - Primary and secondary sexual features. Male: in the inner sac of the aedeagus (Figs 50-52) AC strongly developed, reverse V-shaped with a thick base, other structures much weaker. Sternite VIII (Fig. 57) in the middle ofposterior edge pulled out (posteriorly pointed), tergite X (Fig. 58); female: unknown. Comparative notes - Closely related to T. makokouensis, with which they have the setation type in common and several aedeagal features. Also they are the two largest species of the ones currently known from the area. Uniquely, in this species the middle ot the apical edge of sternite VIII in males is pulled out in a point. Notable for its very fine pronotal punctation, too. Etymology - The name refers to the type locality of the species. Thinodromus thoracicus GlLDENKOV, 2000 (Figs 60, 62, 70-73) Studied material - Paratypes: Sierra Leone: (no further data), bank of stream (2 males, 2 females HNHM). Description - Measurements (in mm, n = 4): HW = 0.52 (0.48-0.56); TW = 0.48 (0.43-0.52); PW = 0.63 (0.59-0.66); SW = 0.74 (0.72-0.76); AW = 0.82 (0.76-0.88); HL = 0.30 (0.29-0.32); EL = 0.17 (0.16-0.18); TL = 0.06 (0.06-0.07); PL = 0.43 (0.40-0.46); SL = 0.72 (0.66-0.76); SC = 0.66 (0.60-0.72); BL = 3.04 (2.76-3.40); FL = 1.53 (1.36-1.72) mm. - Colour. Moderately shiny, body strongly reddish medium brown, legs and mouthparts a tad lighter, terminal two antennomeres and sometimes tip of 9th much lighter. Head a little darker than other main body parts. Head strongly transverse, temples not strongly developed but well marked. Antennái segments more conical with conspicuous basal ridge, strongly dilating apically, antennomeres 4-5 2.25-2.50x longer than broad, antennomere 9 about 1.30 longer than broad (in females almost the same), antennomre 10 much shorter than the neighbouring ones. Pronotum also transverse, posterior half of pronotal side almost straight or very gently concave. Pronotum with two broad oblique depressions on the lateral parts of disc, the middle longitudinal stripe very gently depressed, flat. Reflexed lateral margin not visible on pronotum (from strictly dorsal view), but a thin reflexed margin exists on the posterior edge. Elytra together much broader than long (1.31 x), dilating towards apex, inner-anterior part of disc gently impressed transversally. - Punctation and microsculpture. Head punctation rather fine, puncture interspaces usually 1/2-3/4 of puncture diameters. Pronotal punctation only a little more coarse (or more apparent because of the lack of microsculpture). Elytral punctation about twice as coarse as the pronotal one, appears rather deep. Abdominal terga with punctation more similar to that of the head, shallow and irregular punctation, interspaces as large as average puncture diameters. Microsculpture apparent only on head, which makes it appear more dull. - Pubescence. Setation uni-sized, semierect, hairs rather short. Abdominal setation composed of very thin hairs of medium length and density. Annls hist.-nat. Mus. natn. hung. 101, 2009
