(Figs. 85a–g; 86a–f)  
 Diagnosis. The male is closely related to that of P. platti. They differ in the length of the dorso-lateral projection of the gonostylus, which is 1,5 times longer than broad in P. platti and about 3,0 times longer than broad in P. rozeni. The female is closely related to that of P. semipastina. They differ in the density of scutal punctation. The scutum is sparsely punctate in P. semipastina (i = 3,0d) and more densely punctate in P. rozeni (i = 2,0d).   
 Description   
 Female. Bl = 4,7–4,9mm. General habitus (Fig. 85e). Head. L = 1,3–1,4mm; W = 1,5–1,7mm. Head wider than long (Fig. 85a). Integument black except mandibles, malar area and clypeus partly reddish-brown. Face predominantly shiny and with loose, greyish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus strongly and moderately densely punctate; surface shiny. Clypeoantennal distance 0,3mm. Supraclypeal area with punctures well separated; surface strongly and completely reticulate. Paraocular area strongly and densely punctate; surface extensively and strongly sculptured. Antennae brownish. Mesosoma. L = 0,9–1,0mm; W (ITS) = 1,0– 1,1mm. Integument black. Scutum shiny; surface completely reticulate; disc sparsely punctate (i = 2,0d) (Fig. 85b). Scutellum as illustrated in Fig. 85c. Scutum, scutellum, metanotum, mesepisternum and propodeum with mostly greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 85c; propodeum and marginal region of posterior truncation slightly shiny; surface completely reticulate. Wings. Hyaline. Legs. Integument brownish. Vestiture mostly greyish. Ts strongly serrate, with about 5 broad, oblique projections (Fig. 85f). Bp as illustrated in Fig. 85g. Metasoma. L = 2,2–2,7mm; W = 1,5–1,6mm.

Integument black except mandibles, malar area and clypeus sometimes partly reddishbrown. Clypeus, supraclypeal area, paraocular area and vertex covered with erect, greyish hairs. Mandibles simple. Antennae brownish. Flagellomeres of normal structure (not knotty). A4 as long as A3. Mesosoma. L = 0,9–1,0mm; W (ITS) = 1,0– 1,1mm. Integument black. Scutum polished; sparsely punctate (i = 2,0–2,5d); surface partly chagreened anteriorly. Scutellum as illustrated in Fig. 86b. Scutum, scutellum, metanotum, mesepisternum and propodeum with greyish to dark greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 86b; propodeum slightly shiny; surface completely reticulate and sparsely punctate. Marginal region of posterior truncation slightly shiny and extensively reticulate. Wings. Hyaline. Legs. Integument reddish-brown. Vestiture greyish. Metasoma. L = 2,4–2,6mm; W = 1,4–1,5mm. Integument reddish to brownish-black; T1–T2 extensively reddish; T3–T6 extensively brownish to blackish; margins mostly pallid brownish and broadly translucent (Fig. 86c). Apical plate broad; pointed apically. Posterior margin of S4 with a sparse row of 6 very strong, long, curled, erect bristles. Metasomal sterna S5–S6 without dense hair patches (Fig. 86d). Genitalia.
