The genus Thinodromus in West-Central Africa ( Coleoptera) 41 Thinodromus gabonicus sp. n. (Figs 2-3, 11, 16-18, 29-30, 67) Type material - Holotype (male): "Gabon, [Ogooue-Ivindo,] Makokou (43) [00°34' N, 12°52' E], 29.1.1963, [leg.] H. Coiffait, Mission Biologique au Gabon, P. P. Grasse Directeur" (coll. COIFFAIT, MNHN). Paratypes (54): same data as holotype (3 MNHN, 2 HNHM, 1 BMNH, 1 MRAC); Gabon, [Ogooue-Ivindo,] Belinga (202) [01°08' N, 13°07' E], 13. III. 1963, [leg.] H. Coiffait, (29 MNHN, 1 FMNH); same but (119) (1 MNHN); same but (119L) 12.111.1963,(1 MNHN); same but (219L), (1 MHNG); Gabon, [OgooueIvindo,] M'Vadi (201L) [01°13' N, 13°12' E], 13.III.[19]63, [leg.] H. Coiffait, (10 MNHN, 1 BMNH, 1 MRAC, 1 MHNG, 1 FMNH). Description - Measurements (in mm, n = 3): HW = 0.58 (0.56-0.60); TW = 0.50 (0.48-0.52); PW = 0.69 (0.66-0.70); SW = 0.85 (0.82-0.88); AW = 0.90 (0.88-0.92); HL = 0.33 (0.30-0.36); EL = 0.22; TL = 0.02; PL = 0.48 (0.44-0.50); SL = 0.77 (0.74-0.80); SC = 0.70 (0.66-0.72); BL = 3.32 (3.10-3.50). FL = 1.69 (1.56-1.78) mm. - Colour. Body moderately shining, very dark reddish-brown, almost black, supraantennal processes lighter. Legs dark brown, apices of tibiae and tarsi lighter. - Shape and sculpture. Head rather transverse, temples indistinct, eyes occupy sides of head. Antennái segments ovoid, antennomeres 4-5 1.33-1.48x longer than broad, 9-10 1.03-1.15x broader than long (in females 1.10-1.23X longer than broad and 1.19-1.35x broader than long, respectively) (Figs 2-3). Pronotum strongly transverse, side margin well-noticeably concave before posterior angles; this may only be slightly so in the other species. Pronotal horseshoe-shaped impression strong; disc with a shallow impression anterio-medially, but dual impression on middle hardly noticeable. Reflexed margin broad, laterally rather pronounced, laminar, posteriorly hardly noticeable. Elytra together slightly ( 1.23x ) broader than long, dilating towards apex, anterior half of disc uneven surfaced, with slight protuberances at the sides of the (usually impressed and microsculptured) postscutellar area - Punctation and microsculpture. Head punctation rather strong, dense, punctures unequal sized. Pronotal punctation strong, interspaces at least 1/2-3/4 puncture diameters (puncture sizes not even). Elytral punctation strong, interspaces about 1/2-3/4 diameters. Punctation on abdomen moderately strong, puncture diameters slightly larger than interspaces, more sparse towards apex. No microsculpture anywhere on body except posterior pronotal corners, where punctation diminishes into coriaceous ground sculpture. - Pubescence. Setation with uni-sized hairs, but everywhere, especially on pronotum, longer than usual for this pubescence pattern. Hairs on elytra shorter and very uniform (equal length and thickness). Abdominal terga with some very long setae. - Primary and secondary sexual features. Male: in the inner sac of the aedeagus (Figs 16-18) all sclerites thin, thread-like, AC a conspicuous, reverse V-shaped structure. Sternite VIII (Fig. 29), tergite X (Fig. 30); female: ringstructure (Fig. 67). Comparative notes - This species can be distinguished from others by its unusually strong pronotal punctation, broad and concave pronotal lateral margin and rather long hairyness. Strength of elytral punctation is similar to that of T. decorsei. Etymology - The name refers to the type locality of the species. Annls hist.-nat. Mus. natn. hung. 101, 2009
