Makranczy, Gy.: The genus Thinodromus Kraatz, 1857 in West-Central Africa (Coleoptera, Staphylinidae: Oxytelinae)
38 Gy. Makranczy Bequest, B.M. 1955-147.; Lectotypus Trogophloeus decorsei Cameron, des. Makranczy, 2001; Thinodromus decorsei Cameron det. Makranczy, 2001" (BMNH). Paralectotype (2): "Museum Paris, Moyen Chari, Fort Archambault, Ba-Karé ou Boungoul, Mission Chari-Tchad, Dr. J. Decorse, 1904; Avril; Type; Paralectotypus Trogophloeus decorsei, des. Makranczy, 2002; Thinodromus decorsei Cameron det. Makranczy, 2002" [other specimen with identical locality labels] (1 male, 1 female coll. générale, MNHN). Lectotype and paralectotypes are designated in order to fix the identity of this species, for the express purpose of nomenclatural stability. Other material - Tchad [Chad]: district de Kanem [Prefecture du Kanem, approx. 15°00' N, 16°00' E], VI. 1958, [leg.] P. RENAUD (1 male MRAC, 1 male HNHM). Description - Measurements (in mm, n = 5): HW = 0.61 (0.59-0.64); TW = 0.51 (0.50-0.52); PW = 0.68 (0.66-0.72); SW = 0.82 (0.79-0.90); AW = 0.90 (0.88-0.96); HL = 0.36 (0.35-0.37); EL = 0.25 (0.23-0.28); TL = 0.02 (0.02-0.02); PL = 0.47 (0.44-0.50); SL = 0.75 (0.72-0.81); SC = 0.70 (0.68-0.76); BL = 3.37 (3.00-3.60); FL = 1.67 (1.52-1.84) mm. - Colour. Moderately shiny (more than average), body dark blackish brown, legs and antennae dark brown, tips of supraantennal tubercles somewhat lighter. - Shape and sculpture. Head rather transverse, temples short, but well visible, eyes mostly occupy the sides of head. Antennái segments ovoid, antennomeres 4-5 1.14-1.20x longer than broad, antennomeres 9-10 1.14-1.21 x broader than long (in females antennomeres 4-5 1.17-1.22x broader than long, antennomeres 9-10 1.44-1.6lx broader than long). Pronotum also transverse, posterior half of pronotal side more or less straight. Pronotum with moderately deep horseshoe-shaped impression, its side branches anteriorly do not reach much beyond the horizontal middle-line of pronotum. Reflexed lateral margin medium thin, a fine margin even apparent at the posterior edge. Elytra together 1.23x broader than long, slightly dilating towards apex, extremely gently impressed in anterior half of disc. - Punctation and microsculpture. Head punctation medium coarse, not very dense, puncture interspaces at least 3/4 of the diameter. Pronotal punctation similarly moderately deep, puncture sizes rather even, but interspaces vary (between a third to full puncture diameter). Elytral punctation slightly but noticeably more coarse and deep, average interspace is half of a puncture diameter. Abdominal punctation rather coarse, similar to that of the elytra, getting more sparse posteriorly on terga. No apparent microsculpture anywhere on the body except posterior pronotal corners, where punctation diminishes into coriaceous ground sculpture. - Pubescence. Setation uni-sized, semierect, hairs are rather long and sparser than average (most apparent on elytra). 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 6-8) AC well-developed but rather thin, other sclerites less prominent, sternite VIII (Fig. 25), tergite X (Fig. 26); female: ringstructure (Fig. 65). Comparative notes - Elytral punctation has same roughness/depth as in T. gabonicus , but punctation of the pronotum is very different. It has the most transverse antennomeres of all known species in the region. Outside the region it is rather similar to T. dasys GLLDENKOV, 2000, described from South Africa. Annls hist.-nat.
