Body size. Body length (n=10): 12.7–15.7 mm. Wing length (n=10): 9.2–11.6 mm.
Redescription. MALE ( Fig. 2 View FIGURES 1–10 ). Head. Eye bare; holoptic, touching for at least 4 times length of ocellar triangle, facets enlarged in dorsal half. Frons black; with black-brown pollinosity; dispersed pilosity of short pale pile, along dorsal margin longer dark pile; rugose area shining black, occupying most of frons. Face shining black; with greyish pollinosity dorsally and ventrally of facial tubercle; dispersed pilosity of short pale pile; facial tubercle elongated, moderately pronounced. Three tiny silvery maculae present along inner margin of eye. Occiput dorsal third shining black; ventral two-thirds with conspicuous silvery pollinosity, ventrally with dispersed pale pile. Antennal segments black to black-brown; arista yellow-brown, in basal half with long pile equal to width of pedicel.
Thorax. Scutum and scutellum mainly shining black, at most with weakly developed black-brown pollinosity. Devoid of pilosity except for tiny dark pile which are hardly visible, rarely somewhat more extensive towards medial part of scutum; lateral margins dorsally of anepisternum with long black pile. Pleural sclerites (except meron, and anterior anepisternum) covered with long whitish or pale yellowish pile, more extensively black along dorsal and ventral parts.
Legs. Predominantly black to black-brown. Fore and mid leg with tibia silvery in basal third to fourth dorsally, ventrally less so; with short black pilosity, except in silvery part where pale. Hind leg, silvery part on tibia restricted to dorsal side and for basal sixth at most; hind femur ventrally with few longer pale pile, with poorly developed protuberance and tuft of dense black pilosity in apical fifth.
Wing ( Fig. 38 View FIGURES 37–48 ). Hyaline, sometimes slightly fumose. With narrow black-brown marking of microtrichia, along anterior margin from base to junction of vein R 4+5 with wing margin; extending posteriorly in basal half of wing for almost entire width, and with a marking covering crossvein r-m. Calypters black, except basal part where paler; with fringe of black pile.
Abdomen ( Fig. 62 View FIGURES 61–72 ). Mainly shining black; terga 2–4 partly with black-brown pollinosity except for bullae and lateral plates. Tergum 2 with one medial bulla, and two slightly rugose lateral plates, distal from lateral plate with macula of silvery pile. Terga 3–4 with one medial and two lateral and poorly developed bullae; macula of dense golden pile between medial and lateral bullae. Lateral margin of tergum 2 in posterior half, and tergum 3 over entire length with long pale yellowish pile. Sterna black to black-brown; with conspicuous long pale yellowish pile, except sternum 4 where black. Male genitalia as in Fig. 86 View FIGURES 85–100 .
FEMALE. As male except for the following character states. Eye, facets of equal size; dichoptic. Frons ( Fig. 22 View FIGURES 21–28 ) black; with brownish pollinosity and short dispersed black pile; medially with fascia of longer golden pile over entire width, for height subequal to twice length of ocellar triangle; rugose area equal in height to 2–3 times length of ocellar triangle; near antennal insertion with small greyish transverse maculae reaching eye margin but not forming a complete transverse fascia. Facial tubercle strongly pronounced. Abdomen, bullae on terga 3–4 more pronounced; maculae on terga 3–4 less developed, with dispersed pale yellowish pile; pile along lateral margin of terga 2–3 less developed, shorter; sterna with widely dispersed short pale and dark pile.
Distribution. Congo (DR), Tanzania, Uganda.
Comments. This species is very similar to P. bullata but can be readily differentiated by the maculae of golden pile on abdominal terga 3–4 in the male, and the golden patch on the frons in the female. Both species occur sympatrically in a number of locations and have largely overlapping distributional ranges. The mean p-distance between both species is 7.9 % and much larger than the 0.2 % mean intraspecific p-distance for P. bullata (we had only one DNA barcode for P. aurigera ).
