Eighteen New Oriental Species Of Poecilosomella Duda (Diptera: Sphaeroceridae) Author Papp, L. text Acta Zoologica Academiae Scientiarum Hungaricae 2002 48 2 107 156 journal article 10.5281/zenodo.12587600 2064-2474 12587600 Poecilosomella pilipino sp. n. ( Figs 46–49 ) Holotype male ( ROM ): PHILIPPINES , Negros , Oriental : Cuernos de Negros , 7 km W. Valencia , 29 JUN – 8 JUL 1987 . DC Darling, E. Mayordo. ROM 873061 – 1 ° rainforest edge, 700 m , Malaise w/pans. Paratypes : 1 male ( HNHM ): same as for holotype ; 1 male ( ROM ): ibid., 8–15 JUL 1987 , ROM 873062 . Measurements in mm: body length 2.36 ( holotype ), 2.33 (both paratype males), wing length 2.05 ( holotype ), 1.95, 2.23 ( paratypes ), wing width 0.86 ( holotype ), 0.90 and not measurable ( paratypes ). Mesonotum and abdominal tergites dark grey dusted. Facial plate reddish yellow, occiput and orbitalia dark brown, most parts of frons dirty reddish, except for the silvery spots. Two closely placed fronto-orbital pairs. Antenna reddish, first flagellomere infuscated. Arista long with rather long aristal cilia. Three pairs of rather thin ifr . Scutellum longer than broad. Two pairs of almost equally long katepisternals. Male fore tibia ( Fig. 48 ) medially (ventrally) with extremely long hairs in its whole length: longest hairs on male fore tibia as long as 2/3 length of tibia. Also fore femora with long hairs ventrally. Fore tarsomeres dorsally with setulae longer than diameter of tarsomeres. Mid tibia ventrally with long hairs (as long as diameter of tibia), i.e. like P. pectiniterga (cf. HAYASHI 1997 : fig. 8). No ventroapical seta on mid tibia but with 3 curved, hair-like setae instead. Wings without vein appendage on R 2+3 , dark spots as in P. insularis HAYASHI , 1997 . Second and third costal sections 0.585 mm vs. 0.57 mm ( holotype ), ratio 1.03. Intercrossvein section of vein M 0.145 mm , dM-Cu cross-vein 0.155 mm long. Epandrium with a limited number of rather thin setae. Cerci weakly sclerotized. Subepandrial sclerite without pecularities. Anterior lobe of surstylus with very long hairs ( Fig. 49 ), posterior lobe larger than in P. pectiniterga . Postgonite ( Figs 46–47 ) slightly bent in its basal 3/4, distal part curved surstylus, lateral view. Scales: 0.5 mm for Fig. 48 , 0.2 mm for Figs 46, 49 , 0.1 mm for Fig. 47 and broad, apical part more membraneous. Phallus rather large compared to the phallapodeme ( Fig. 46 ). Distiphallus narrowing, apical part slightly downcurved, apical threadlike process about twice as long as phallus ( Fig. 46 ). Figs 46–49. Poecilosomella pilipino sp. n. , paratype male. 46 = genital complex with postgonite, lateral view, 47 = postgonite in higher magnification, lateral view, 48 = fore tibia, anterior view, 49 = Female unknown. Distribution. Known from the Philippines only. Etymology. The name (noun) means a male from the Philippines . P. pilipino sp. n. is a member of the P. pectiniterga species group. The very long hairs along the whole length of male fore tibia are very characteristic, and the details of the male genitalia provide reliable characters for its identification. As stressed in the introductory part, all the identifications (published or not) made between 1964 and 1997 must be checked.
