( Figs 58–63 , 71 ) Holotype male ( HNHM ): [ République du Congo ]: Congo Brazzaville , ORSTOM park, 2. I. 1964 , No. 572, J. Balogh – A. Zicsi. Paratypes : 1 female ( HNNM ): same as for the holotype ; 7 males 3 females ( HNHM , 3 m and 1 f in DEI ): Togo : Région des Plateaux : Zogbégan , village part Zogbégan-Carriére ( SE of Badou ), at creek Elèbè , 7°34’50”N , 0°40’03”E , 650 m , 20.– 25.4.2008 , leg. M. v. Tschirnhaus , Tg 1888 [V-shaped valley near cocoa-plantation downstream of village, remains of secondary rainforest, dense bank vegetation, dead wood, leaf litter, mud and sparsely running water near creek spring, swept, filled into eclector] . Measurements in mm: body length 2.64 ( holotype ), 2.29–2.81 ( paratypes ), wing length 2.05 ( holotype ), 1.76–2.15 ( paratypes ), wing width 1.01 ( holotype ), 0.79–1.00 ( paratypes ). Body mainly dark brown, silvery pattern of head, mesonotum and scutellum as in its congeners. Facial plate dark yellowish red, frons reddish brown. Antennae are red on holotype , brownish red on paratypes . Aristal cilia long, up to 0.04 mm . Anterior fronto-orbital seta subequal to posterior pair. (2)–3–(4) pairs of medium long and rather thin infraorbital setae. Anterior katepisternal seta strong, subequal to ( holotype ) or 4/5 length ( paratypes ) of posterior pair. Wings ( Fig. 71 ) patterned. Wing membrane light brownish, veins light brown, but dark brown on areas of dark spots. Darker brown spots on humeral vein down to base of M, around apical section of R 2+3 , on bifurcation of R 2–5 , incl. R1. Apical section of R 2+3 perpendicular to costa but without a vein appendage at curvature. Longitudinal section of R 2+3 S-shaped. Vein R 4+5 gently curved up to costa and as a consequence, terminates as far from wing apex as a virtual continuation of M would be. mm for Figs 59–63 Figs 58–63. Poecilosomella setimanus sp. n. , male postabdomen and genitalia. 58 = sternite 5 of a paratype, ventral view, 59 = ventral part of epandrium with cerci and subepandrial sclerite (holotype, most of the epandrial setae omitted), 60 = surstylus of the holotype in broadest extension (a sublateral view), 61 = postgonite of the holotype, broadest extension, in a ± lateral view, 62 = same, of a paratype, 63 = basiphallus with postgonite of a paratype, lateral view. Scales: 0.2 mm for Fig. 58, 0.1 Costa not continued, or only slightly continued over apex of R 4 +5 (by 0.01 mm ). Sub-basal thorn of costa 0.19 mm long ( holotype ) . Setae on first costal section max. 0.10 mm long. Second costal section definitely shorter than third ( 0.49 mm vs. 0.60 mm on holotype ) . Inter-crossvein section of M 0.19 mm , hind cross-vein 0.17 mm ( holotype ) . Legs dark brown, both ends of tibiae as well as a broad ring on the middle of tibiae dirty yellow. Setosity of legs very strong. Anterodorsals on mid tibia: 11/63 (small), 16/63 (medium), 24/63 (very long and thick), 37/63 (medium), 47/63 (very long and thick). Posterodorsals: 11/63 (small), 15/63 (medium long), 21/63 (very long and thick), 39/63 (long and thick), 49/63 (very long and thick). An extremely long and thick anteroventral (!) seta present at 38/63. Several short, slightly curved ventro-apicals discernible. Mid basitarsus with rows of strong anteroventrals and posteroventrals of c. 8–9 setae each. A similar anterior row also present. Male fore tibia and metarsus as well as second tarsomere with long hairs ventrally and anteroventrally. Male fore femur anteroventrally with similar hairs. Tarsomeres 4 and 5 of all tarsi brown. Basal 2/3–3/4 of fore basitarsus dark brown. Also hind tarsi mainly yellow but dorsal half of basitarsus and that of second tarsomere dark brown. Male sternite 5 ( Fig. 58 ) asymmetrical, with less melanised medial plates. The two parts of the medial plate separated by a thin gap, caudal part wholly covered by short hairs. Ventrally placed part of sternite 6 narrow. Sternites 6+7 strongly fused and much shorter than sternite 8. Epandrium short but not small, with rather long setae. Cercal (ventral) part of the complex short, without long setae, most ventrally with a blunt projection ( Fig. 59 ). Medial part of hypandrium thin and shorter than phallapodeme. Surstylus ( Fig. 60 ) compact, apical lobes broad and short, caudal lobe terminates in a short small process (sharp in the broadest view of surstylus), apical thorn rather short. No long setae on surstylus. Postgonite ( Figs 61–62 ) comparatively short and broad, proclinate with blunt apex, ventrally and apically with numerous long hairs. Threadlike process of distiphallus long, forming almost a complete ring of a diameter of the distiphallus. Phallapodeme thin, bacilliform. Caudal part of basiphallus bulbous, its ventral part less sclerotised with numerous peg-like thornlets ( Fig. 63 ). Etymology. Its specific epithet ‘setimanus’ (noun) means setose hand, referring to its long setose basitarsus.
