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

52 Gy. Makranczy Thinodromus mauritanicus sp. n. (Figs 39, 44-46, 53-54) Type material - Holotype (male): "Azougi, pr. Atar, Adrar mauritanien, [= Mauritania, Azougil, 20°29' N, 13°07' W,] leg. B. de Miré, 1 l.I.[19]48." (coll. JARRIGE, MNHN). Paratypes (2 males [aedeagi distorted]): same data as holotype (coll. JARRIGE, MNHN). Description - Measurements (in mm, n = 3): HW = 0.65 (0.61-0.70); TW = 0.50 (0.48-0.52); PW = 0.75 (0.70-0.80); SW = 0.88 (0.84-0.92); AW = 0.96 (0.92-1.02); HL = 0.39 (0.38-0.40); EL = 0.27 (0.26-0.28); TL = 0.00; PL = 0.51 (0.48-0.54); SL = 0.79 (0.76-0.82); SC = 0.69 (0.64-0.74); BL = 3.20 (3.00-3.50). FL = 1.73 (1.66-1.82) mm. Colour. Body moderately shining, very dark reddish-brown, almost black. Supraantennal processes lighter, yellowish. Legs medium to dark brown, tibiae without their apices the darkest. - Shape and sculpture. Head rather transverse. Antenna! segments ovoid, antennomeres 4-5 1.25- 1.50x longer than broad, antennomeres 9-10 1.00- 1.26x broader than long. Pronotum very transverse, only very slightly concave before posterior angles. Reflexed lateral margin broad. Anterior margin with very slight depressions near the anterior angles. With moderately deep horseshoe-shaped impression, dual impression in middle of disc and depressions along anterior edge very shallow. Reflexed lateral margin laminar, rather wide, anteriorly absent, posteriorly fine. Elytra together slightly (1.22x) broader than long, dilating towards apex, elytron with a shallow and moderately large impressed area in the anterior half of disc. - Punctation and microsculpture. Head punctation with moderately deep punctures, much closer than their diameter. Pronotal punctation consists of variously sized punctures, almost as far away as their diameter (so sparser than on head). Elytral punctation is deep and close, interspaces much smaller than diameters. Abdominal punctation with moderately small, irregularly spaced punctures, getting rather sparse towards apex. No apparent microsculpture anywhere on the body except posterior pronotal corners, where punctation diminishes into coriaceous ground sculpture. - Pubescence. Setation uni-sized, rather dense, but with varying hair sizes and thicknesses, like in T. kedougouensis. On abdominal terga among the usual sized setae with some longer hairs. - Primary and secondary sexual features. Male: in the inner sac of the aedeagus (Figs 44-46) AC distorted H-shaped, other sclerites rather small, weakly developed. Sternite VIII (Fig. 53), tergite X (Fig. 54); female: unknown. Comparative notes - Its unusually transverse pronotum, unusual formation of the apical edge of male sternite VIII distinguishes it from other congeners. Based on aedeagal features, this species has a closest relative in T. odzalensis, although externally the similarity is more distant, T. makokouensis and T. odzalensis seem to be more alike. This group of three species have a tendency for unusual formation of the apical edge on male sternite VIII; while in most other species it is membraneous and gently pulled out in the middle, here appears to be more sclerotized and either pulled out in a point or two humps. Etymology - The name refers to the type locality of the species. Annls hist.-nat. Mus. natn. hung. 101, 2009
