Patellapis (Chaetalictus) rozeni sp. n. Timmermann

( 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).

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. 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. Genitalia as illustrated in Fig. 86f ; gonocoxa extensively dull; gonostylus with dorso-lateral, hyaline projection; projection hairless.
