Papp, L.: A review of the Afrotropical species of Poecilosomella Duda (Diptera, Sphaeroceridae)

Thoracic chaetotaxy as in its related species, i.e. lh,lnp,l prealar (anterior intraalar), 1 sa, 1 pa, 2 ia, 2dc,2sc pairs. One moderately long but rather thick katepisternal bristle posteriorly and 1-2 more anterior katepisternal hairs. Male middle tibia with a very short va, armature of tibia similar to that of arnaudi butpds in middle third and ads in proxial third longer an much thicker. Fore and middle tarsi yellow (reddish yellow), 5th tarsomeres dark, hind tarsi with 1st, 2nd, 4th and 5th tarsomeres dark (at least dorsalty). Wings light brownish, except for alar base proximal to humeral vein and areas of alar spots, veins ochreous. Costa basalty and at apex of Rl,Rs fork and apical part of R2+3 usually with a short vein appendage. Ratio of second and third costal sections 1.06 to 1.415, in absolute values 0.66-0.744 mm and 0.526-0.628 mm. Intracrossvein section of M 0.179-0.218 mm, hind crossvein 0.171-0.180 mm, ratio 1.00-1.21. Male subanal plate (and periandrium) with a pair of blunt lateral processes, subanal plate medially with a pair of dentate processes (Ftg. 6). Distiphallus (Fig. 7) rather robust, its thread-like process much shorter than in arnaudi. Postgonite (Fig. 7) wide, more angulate than that of arnaudi. Phallophore oblong ventrally and covered with thick and comparativery long setae. Gonostylus (Fig. 8) trilobed, ventral (ventromedial) process with a long and blunt tooth, medial lobe hardly sclerotized, upper lobe rather long with moderately long bristles. Female T8 bipartite (Fig. 9), S8 weakly sclerotized, mediocaudalfy with 3-4 short bristles. Cerci with two long and one shorter bristles. Sperma thecae (Figs 10,11) globular, sclerotized terminal part of the ducts rather long with scale-like short setulae. Eggs (Fig. 12) unique, chorion with hexagonal sculpture, extremely long spiracular processes (Fig. 13). Holotype male: South Africa: Cape Province, Stroms Rrvier, elev. 200 m, IV-20-58. E. S. Ross & R. E. LEECH collectors (CAS Type No. 16042). - Paratypes: 42d, 169 (27d, 11 9 CAS, 15d,5 9 HNHM): same data as for the holotype. P. capensis sp. n. belongs to the longecostata species-group. Its body is slightly bigger, the vein appendage of the Ä2+5vein is conspicuous, the features of the male genitalia are all very characteristic.
