Fig. 51

Description:

Male. Similar to female of P. terebrans sp. n. (wing with oblique crossband) and male of P. ciliata , except as follows:

Face: With supraclypeal sclerite as high as wide.

Wing: 5.9 mm long, with hyaline costal cell; pterostigma and basal half of cell r 1 yellow; distance from wing base to apex of vein R 1 3.9 mm; vein R 2+3 with apically slightly bifurcated (left wing) or simple (right wing) stump vein; crossvein r–m in hyaline area; wing in apical part with entire oblique brown crossband, unbroken and narrowed from R 2+3 vein through vein dm–cu to posterior margin and pale brown apical portion of r 1 cell; wing apex hyaline, without conspicuous marginal darkening. Upper calypter long black ciliate, as in P. callosa sp. n.

Body and legs:Yellow, except tibiae and tarsi brownish yellow; abdomen with blackish brown tergites 1+2, 3 and 4 (except lateral margins yellow) and yellow tergite 5.

Male genitalia (in situ; not dissected): As depicted for P. ciliata .

Material examined: 1♂ NIGERIA: “Jema’a” [9.4667 °N 8.3833 °E], 15.ix.1971, H. Polizar, “ Metropina n. sp. ” (G.C. Steyskal’s handwriting) ( USNM) .

Remarks: This specimen shares the elongate wing with oblique crossband with the female holotype of P. terebrans sp. n. and very probably is conspecific with it, but further evidence for its identity is needed.
