Diagnosis
Arista pubescent; scutum with two transverse bands; postpronotum white; scutellum white; anatergite and katatergite completely white; legs yellow with femora dark yellow to brown; wing, anterior apical band complete, touching discal band, posterior apical band present, discal band reaching posterior margin; abdomen mainly shining black-brown.
Description
Head. Antennal segments brown. Arista pubescent, rays about twice as long as width of base of arista. Frons ventral 2/5 yellow-white, dorsal part orange-brown. Two frontals, placed parallel to medial eye margin; two orbitals, placed slightly convergent with anterior orbital located more medially. Face white; with broad brown band occupying 2/5 to 1/2 of face near antennal implant. Occiput yellow, with two darker, largely confluent, patches in dorsal part, sometimes more extensive.
Thorax. Scutum shining brown; dark dispersed pilosity; two transverse bands with silvery pilosity and microtrichosity, one anteriorly of transverse suture, second, less developed, band near dorsocentrals; second band sometimes without microtrichosity or strongly reduced. Postpronotum white. Anepisternum brown, with white band occupying posterodorsal part, its ventral margin not reaching posteroventral corner; with pale pilosity except for few darker setulae in posteroventral corner; one anepisternal seta. Anatergite and katatergite white. Scutellum white. Subscutellum brown. Legs pale yellow, femora darker coloured, from dark yellow to brown.
Wing ( Figure 2F View Figure 2 ). Wing bands brown, well developed. Basal part of wing brown, subbasal irregular spots and streaks present. Anterior apical band completely filling cells r 1 and r. Posterior apical band touching anterior apical band. Subapical band isolated. Discal band reaching posterior wing margin; touching anterior apical band near pterostigma; well separated from subbasal spots and streaks, at least in cell cu 1. R-M ratio 0.84–1.00.
2+3
Abdomen. Shining dark brown, posterior 1/4 to 2/3 of tergites 2 and 4 with greyish band, anteriorly more orange; tergite 5 with median orange-brown line.
Body length. 3.40–5.40 mm; wing length 3.80–5.05 mm.
Female. As male. Female terminalia, oviscape about as long as or slightly longer than abdominal tergites, shining brown, with black pilosity. Aculeus ( Figure 3H View Figure 3 ) about 15 times longer than wide; aculeus tip ( Figure 4J View Figure 4 ) narrow, simply pointed.

Distribution
Cameroon, Congo (D. R.), Ethiopia, Kenya, Nigeria, Tanzania, Uganda and Zimbabwe. Probably also found in Congo (Brazzaville) (cf. material examined).
Hosts
Recorded from Agelanthus sansibarensis , Loranthus sp. and Phragmanthera usuiensis (Oliv.) M.G. Gilbert (all Loranthaceae ). Also one specimen apparently from Ficus although this record is questionable (see also under P. formosula ).
Comments
This is the most abundant and widespread species within the genus. Wing banding is slightly variable in this species, especially regarding separation of discal band from subbasal streaks. However, all specimens with slightly deviant wing banding (those listed as tentatively placed here) are grouped under P. pulchella since no additional characters could be found to separate them from the others.
