Patellapis (Chaetalictus) virungae sp n. Timmermann

( Figs. 90a–g ; 91a–f )

Diagnosis. The male is similar to that of P. africana . Both have 14 erect bristles on the posterior margin of S4 and hairy dorso-lateral projections on the gonostylus, but those hairs are much longer in P. virungae than in P. africana . The female of P. virungae is characterised by the scutum and supraclypeal area completely reticulate, a strongly serrate inner hind tibial spur (3–5 oblique projections) and weak whitish apical hair bands on T2–T4 (only present laterally).

Description

Female. Bl = 4,9–5,1mm. General habitus ( Fig. 90e ). Head. L = 1,5–1,6mm; W = 1,6–1,7mm. Head about as wide as long ( Fig. 90a ). Integument black except mandibles and malar area partly reddish-brown. Face predominantly shiny and with loose, greyish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area (slightly) convex in profile. Clypeus coarsely and densely punctate; upper part usually extensively reticulate; sometimes with a median longitudinal depression; 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 coarsely sculptured. Antennae brownish-black. Mesosoma. L = 1,0– 1,1mm; W (ITS) = 1,2–1,3mm. Integument black. Scutum slightly shiny; surface completely reticulate; disc densely punctate (i = 1,0–1,5d) ( Fig. 90b ). Scutellum as illustrated in Fig. 90c . Scutum, scutellum, metanotum, mesepisternum and propodeum with mostly greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 90c ; propodeum and marginal region of posterior truncation slightly shiny; surface completely reticulate. Wings. Hyaline. Legs. Integument brownish-black. Vestiture mostly greyish. Ts strongly serrate, with 3–5 broad, long, oblique projections ( Fig. 90f ). Bp as illustrated in Fig. 90g . Metasoma. L = 2,6–2,8mm; W = 1,7–1,8mm. Integument brownish-black; margins pallid brownish to pale; slightly translucent. Metasomal terga without apical hair bands (sometimes weakly present laterally on T1–T2). Prepygidial fimbria yellowish to pallid brownish. Metasomal terga as illustrated in Fig. 90d .

Male. Bl = 4,8–4,9mm. General habitus ( Fig. 91d ). Head. L = 1,4–1,5mm; W = 1,5–1,6mm. Head about as wide as long. Integument black except mandibles and malar area partly reddish-brown. Clypeus, supraclypeal area, paraocular area and vertex covered with erect, greyish hairs. Mandibles simple. Antennae brownish-black. Flagellomeres of normal structure (not knotty). A4 as long as A3. Mesosoma. L = 1,0mm; W (ITS) = 1,1mm. Integument black. Scutum shiny; densely punctate (i = d); surface completely and finely reticulate ( Fig. 91a ). Scutellum as illustrated in Fig. 91b . Scutum, scutellum, metanotum, mesepisternum and propodeum with whitish to greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 91b ; propodeum shiny; surface completely reticulate and sparsely punctate. Marginal region of posterior truncation shiny and extensively reticulate. Wings. Hyaline. Legs. Integument brownish to pallid brownish. Vestiture mostly greyish. Metasoma. L = 2,4–2,5mm; W = 1,4–1,5mm. Integument brownish-black; margins pallid brownish to pale; slightly translucent. Metasomal terga without apical hair bands. Apical plate broad; rounded apically. Posterior margin of S4 with a row of about 16 strong, long, curled, erect bristles; lateral ones enlarged. Metasomal sterna S5–S6 without dense hair patches ( Fig. 91c ). S7 and S8 as illustrated in Fig. 91f . Genitalia. Genitalia as illustrated in Fig. 91e ; gonocoxa extensively dull; gonostylus with dorso-lateral, hyaline projection; projection with long, curled hairs.
