Description:

Female. In general features, as described for P. callosa sp. n.

Head: Length:height: width = 1.0:(0.8)1.0–1.1:1.1–1.2(1.2), flagellomere 1 brown on apical 0.3–0.5 (missing in holotype). Frons without brown areas, (1.9)1.8× as long as wide in its narrowest part; with 1 proclinate orbital seta and 8–10 irregular setulae as long as orbital seta, on its anterior portion. Face 2.0–2.4× as high as wide; supraclypeal sclerite 1.1× as high as wide. Eye 1.4× as high as long and 1.8–3.0× as high as gena. Ocellar triangle poorly defined, ocellar and postocellar seta moderately developed, longer than orbital seta and as long as lateral vertical seta and half as long as medial vertical seta; lateral vertical seta present. Flagellomere 1.0–1.1× as long as pedicel and 1.4–1.5× as long as proboscis and palp.

Thorax: Shining, almost uniformly pale reddish yellow, with more-reddish vittae on mesonotal scutum (at muscle attachment) and slightly brownish yellow mediotergite; setae and setulae black or brown. Postpronotal seta lacking or present. One presutural dorsocentral (scapular) and 2 postsutural dorsocentral setae, rarely 1 additional presutural seta; smaller dorsocentral setae and/or setulae (indistinguishable or missing in holotype) about half as long as setae in other specimens.

Legs: Yellow coxae, trochanters and femora, and pale brown tibiae and tarsi.All setae and setulae uniformly black, short; no pale dense “grooming brushes”. Claws short.

Wing ( Fig. 12 ): As described for P. richteri except as follows: 5.7–6.9 mm (mean 6.5) long, pterostigma and cell r 1 posterior to it yellow; vein R 2+3 with stump vein, often bifurcated at apex; vein R 4+5 setulose from base to level of R 2+3 apex; crossvein r–m on hyaline background; wing in apical part with pale brown band from anterior margin to M vein; vein dm–cu either on hyaline background or pale brownish, then with crossband broken along vein M. Apical portion of r 1 cell and apices of cells r 2+3, r 4+5 and m hyaline or pale yellow. Distance between wing base and apex of vein R 1 2.6–3.7 mm (mean 3.3). Upper calypter long black ciliate.

Abdomen: Shining reddish brown, brownish setulose. Sternites short and finely setulose. Oviscape (Figs 28, 29) 2.9–4.0 mm (mean 3.5) long, 1.4–1.7× as long as thorax, and about 1.5–1.7× as long as preabdomen, conspicuously longer than distance from wing base to vein R 1 apex but shorter than distance from wing base to vein dm–cu; ventrally on apical 0.85, dorsally on apical 0.8 short brownish setulose; subapically not swollen, about 0.25× as wide as at base and almost parallel-sided in apical one-fifth. Apex of oviscape in profile conspicuously curved dorsally, laterally and laterodorsally with fringe of long setulae 0.6–0.7× as long as oviscape diameter at apex. No trace of sclerotized lobes at base of eversible membrane. Aculeus (Fig. 42) elongate, slightly barbed subapically, 0.48 mm long and 1.2× as long as diameter of oviscape at apex. Spermathecae (two of the three found in the dissected female) as in Fig. 30. Ventral receptacle as in Fig. 31. Holotype (examined): ♀ “ TOGO / Bismarckburg [8.1833°N 0.6833°E], 27.VII–10.VIII.[18]93 / L. Conradt S.” ( ZMHB).
