Body size. Body length (n=10): 8.3–12.5 mm. Wing length (n=10): 7.6–9.4 mm.
Redescription. MALE ( Fig. 9 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 golden brown pollinosity; dispersed pilosity of medium long yellowish to orange pile; rugose area shining black, occupying one-third of entire width and about two-fifths of entire height; with shorter dispersed yellowish to orange pile. Face ground colour black; mainly weakly shining with dispersed golden brown pollinosity, in parts more densely golden pollinosity; dispersed pilosity of short pale pile; facial tubercle elongated, strongly pronounced. Gena colour and pollinosity as face except for orange patch; with long pale pilosity. Occiput dorsal third black, with greyish pollinosity; ventrally more densely golden, with dispersed pale pile. Antennal segments brown to black; arista orange-brown, in basal two-thirds with medium long pile equal to width of pedicel.
Thorax. Scutum black ground colour, with dense orange-brown pollinosity anteriorly, posteriorly weakly shining; covered with dense pile of long orange to orange-brown pilosity. Scutellum as scutum except along anterior and posterior margins more rufous ground colour, extending towards centre in medial part. Pleural sclerites ground colour black, with greyish brown pollinosity; covered with dispersed pile of long golden yellow to orange pile except meron, anterior part of katepisternum and anterior anepisternum.
Legs. Fore leg, femur orange-brown to black-brown, apical margin narrowly paler; with dense short black pilosity, anteriorly and posteriorly longer and partially paler at base; tibia pale in basal fourth, otherwise dark brown; with short black pilosity, except in basal pale area where pale to yellow-orange pile; tarsal segments yellow-orange. Mid leg as in fore leg, except tibia pale for more extended part, at least to basal half, pale to yellow-orange pilosity extending half-way. Hind leg femur orange-brown to black-brown, at extremities narrowly paler; dorsally with long pale to golden yellow pilosity, ventrally with long dark pilosity except in basal part where pale, otherwise short pale pilosity; tibia orange-brown to black-brown; dorsally with short pale to yellow-orange pilosity in basal two-fifths to two-thirds, changing to black distally, ventrally with short to medium-long dense black pilosity; tarsal segments yellow-orange.
Wing ( Fig. 48 View FIGURES 37–48 ). Mainly hyaline to slightly fumose, with dispersed microtrichia covering large or entire parts of cells bc, c, sc, r, bm and cup as well as basal third of cell r 2+3 and basal margin of r 4+5 near crossvein r-m; more densely so at base and in patch at 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. 71 View FIGURES 61–72 ). Mainly black-brown ground colour. Terga 2–4 to variable extent more orange-brown; with shining medial bulla; pilosity with dispersed short to medium long pale to yellow-orange pile, longer along margins. Sterna black-brown, with widely dispersed long pale pile. Male genitalia as in Fig. 92 View FIGURES 85–100 .
FEMALE. As male except for the following character states. Eye, facets of equal size; dichoptic. Frons black ground colour; with golden brown pollinosity; covered with short dispersed yellow-orange pile; rugose area shining brown; occupying one-third of entire width and slightly longer in height than length of ocellar triangle. Legs, fore and mid tibiae with basal pale area more extensive. Wing ( Fig. 49 View FIGURES 49–60 ) more extensively covered with microtrichia, covering most of wing surface except along posterior margin; medial patch also along cross-vein r-m more densely covered. Margins bordering veins somewhat more fumose.
Distribution. Congo (DR), Ghana, Ivory Coast, Liberia, Uganda.
Comments. Syntype specimens of P. noctilio are identical to P. pubipennis except for that the microtichia coverage on the wing is more extensive, in particular in the male, and that the mid and fore tibia has the pale pilosity over the entire length. Other differences outlined in Speiser (1924) appear to be variable and do not enable differentiation between both species. The differences observed do not warrant specific status and we, therefore, consider P. noctilio to be synonymous to P. pubipennis . One specimen in KMMA is labelled as type but is not included in type series. The erroneous labelling is based on the publication by Hervé-Bazin (1914) where he mentions that this specimen belongs to a new species that will be described by Bezzi. There is no indication, however, that Bezzi studied the specimen nor was it included in the original type series as listed in Bezzi (1915). In addition, the specimen belongs to the newly described Phytomia austeni .
