Body size. Body length (n=10): 12.4–13.5 mm. Wing length (n=10): 9.0– 10.3 mm.
Redescription. MALE ( Fig. 7 View FIGURES 1–10 ). Head. Eye bare; holoptic, touching for about twice length of ocellar triangle, facets enlarged in dorsal half. Frons brown to black; with greyish brown pollinosity; dispersed pilosity of medium long pale pile, dorsally longer and darker; rugose area shining black–brown, occupying one-third of entire width and two–fifths of entire height; with shorter dispersed pale pile. Face ground colour black; with dispersed greyish to greyish brown pollinosity, in parts weakly shining black; dispersed pilosity of short pale pile; facial tubercle elongated, moderately to strongly pronounced. Gena colour and pollinosity as face; with long pale pilosity. Occiput dorsal third black, with greyish pollinosity; ventrally more densely yellow-white, with dispersed pale pile. Antennal segments brown to black-brown; arista yellow-brown, in basal half with medium long pile equal to width of pedicel.
Thorax. Scutum and scutellum black ground colour, with dense greyish to greyish-brown pollinosity in anterior half of scutum, posterior part weakly shining black; covered with dense pile of long pale yellowish to greyish pilosity. Pleural sclerites ground colour black, with greyish brown pollinosity; covered with dispersed pile of pale yellow to yellow-orange pile except meron, anterior part of katepisternum and anterior anepisternum.
Legs. Yellow-orange to black-brown. Fore leg, femur black brown, apical margin narrowly paler; with dense short black pilosity, anteriorly and posteriorly longer and pale in basal third; tibia pale in basal third, otherwise orange-brown; with short black pilosity, except in basal third where pale; tarsal segments yellow-orange. Mid leg as in fore leg, except tibia pale for basal half, and pilosity pale over entire length. Hind leg ( Fig. 33 View FIGURES 29–36 ), femur slightly thickened; black-brown; dorsally with long pale pilosity, ventrally with long pilosity pale in basal half and dark in apical half, otherwise short dark pilosity; tibia orange-brown to black brown, sometimes pale at basal tip; dorsally with short pale pilosity in basal third, distally black, ventrally with short to medium-long dense black pilosity; tarsal segments yellow-orange to dark orange.
Wing ( Fig. 45 View FIGURES 37–48 ). Mainly hyaline. Microtrichia along base; also patch in medial part of wing anteriorly from apex of vein Sc, posteriorly along medial part of cell r 1, basal part of cell r 2+3, and into cell r where it reaches the junction of vein M with crossvein bm-cu. Calypters dark with fringe of dark pile.
Abdomen ( Fig. 69 View FIGURES 61–72 ). Mainly black-brown ground colour, sometimes partly more dark rufous. Terga 2–4 with black-brown pollinosity and shining medial bulla; pilosity with dispersed short to medium long pale to yellowish pile, longer along margins. Sterna black-brown, with widely dispersed long pale pile. Male genitalia as in Fig. 90 View FIGURES 85–100 .
FEMALE. As male except for the following character states. Eye, facets of equal size; dichoptic. Frons black ground colour; with greyish brown pollinosity, except in dorsal third where dark brown; covered with short dispersed pale to yellowish pile, except in dorsal third where predominantly black; rugose area shining brown; occupying one-third of entire width and equal in height to at most twice length of ocellar triangle. Wing ( Fig. 46 View FIGURES 37–48 ) more extensively covered with microtrichia, covering anterior half to two-thirds of wing surface, in addition to medial patch along cross-vein r-m more densely, sometimes covering most of wing surface except for posterior margin.
Distribution. Cameroon, Central African Republic, Congo (DR), Ghana, Togo.
Comments. When describing P. pubipennis , based on a specimen from Uganda, Bezzi (1915) already pointed out that an additional specimen (collected in Obuasi, Ghana) was related but differed in a number of morphological characters, considering it a melanic form. Curran (1927a) described P. bezzii , based on a series of specimens collected in Congo (DR) but explicitly refers to the melanic form of P. pubipennis , as recognized by Bezzi, and states that this is the same species. He, however, did not include the specimen from Ghana in the type series.
