Diagnosis. Both sexes of this species are characterised by their elongate face, which is unique within this species-group (in P.sabinae the face is only slightly elongate).

Marginal region of posterior truncation shiny; surface completely reticulate. Wings. Hyaline. Legs. Integument brownish-black. Vestiture whitish to greyish. Metasoma. L = 2,7–2,8mm; W = 1,3–1,4mm. Integument brownish-black except the margins of T pallid brownish; margins extensively translucent. Metasomal terga as illustrated in Fig. 59d . Apical plate broad; rounded apically. Posterior margin of S4 with a row of 18–20 weak, erect bristles. Metasomal sterna S5-S6 without dense hair patches ( Fig. 59e ). S7 and S8 as illustrated in Fig. 59h . Genitalia. Genitalia as illustrated in Fig. 59g ; gonocoxa partly dull; gonostylus with dorso-lateral, hyaline projection; projection with fan–shaped, curled, erect hairs.
