Patellapis (Chaetalictus) abnormis sp. n. Timmermann

( Figs. 94a–g ; 95a–h )

Diagnosis. This species resembles P. renosterveldi , P. sakagamii and P. spinulosa in having the scutum polished and sparsely punctate. Both sexes of P. abnormis are characterised by a coarsely and completely wrinkled basal area of propodeum, which is unusual within this species group.

Description

Female. Bl = 4,7mm. General habitus ( Fig. 94e ). Head. L = 1,3–1,4mm; W = 1,5–1,6mm. Head wider than long ( Fig. 94a ). Integument black except mandibles, malar area, clypeus and paraocular area partly reddish-brown. Face shiny and with loose, greyish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus sparsely punctate; surface shiny. Clypeoantennal distance 0,3mm. Supraclypeal area with small punctures; punctures well separated; surface shiny; finely chagreened marginally. Paraocular area moderately densely punctate; surface partly sculptured; shiny. Antennae reddishbrown. Mesosoma. L = 1,0mm; W (ITS) = 1,2mm. Integument black. Scutum polished; surface partly chagreened anteriorly; disc sparsely punctate (i = 2,0–3,0d) ( Fig. 94b ). Scutellum as illustrated in Fig. 94c . Scutum, scutellum, metanotum; mesepisternum and propodeum with greyish, erect hairs. Basal area of propodeum coarsely wrinkled ( Fig. 94c ); propodeum dull; surface coarsely sculptured and sparsely punctate. Marginal region of posterior truncation dull; surface coarsely sculptured and partly wrinkled. Wings. Hyaline.

Metasoma. L = 2,8mm; W = 1,5mm. Integument brownish-black; margins of T pallid brownish to pale; broadly translucent. No apical hair bands on metasomal terga. Prepygidial fimbria mostly yellowish-brown. Metasomal terga as illustrated in Fig. 94d .

Male. Bl = 4,4–4,6mm. General habitus ( Fig. 95f ). Head. L = 1,2–1,3mm; W = 1,5–1,6mm. Head wider than long ( Fig. 95a ). Integument black except mandibles and malar area partly reddish-brown. Clypeus, supraclypeal area, paraocular area and vertex covered with erect, whitish and greyish, erect hairs. Mandibles simple. Antennae reddish-brown. Flagellomeres of normal structure (not knotty). A4 as long as A3.

Mesosoma. L = 0,8–0,9mm; W (ITS) = 1,0– 1,1mm. Integument black. Scutum polished; sparsely punctate (i = 3,0–4,0d) ( Fig. 95b ). Scutellum as illustrated in Fig. 95c . Scutum, scutellum, metanotum, mesepisternum and propodeum with whitish to greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 95c ; propodeum shiny; surface sculptured and sparsely punctate. Marginal region of posterior truncation polished; surface hardly sculptured. Wings. Hyaline. Legs. Integument brownish. Vestiture whitish. Metasoma. L = 2,1–2,3mm; W = 1,5–1,6mm. Integument brownish-black except discs and margins of metasomal terga pallid brownish to pale; broadly translucent ( Fig. 95d ). Apical plate rounded apically. Posterior margin of S4 without erect bristles. Metasomal sterna S5–S6 without dense hair patches ( Fig. 95e ). S7 and S8 as illustrated in Fig. 95h . Genitalia. Genitalia as illustrated in Fig. 95g ; gonocoxa extensively shiny; gonostylus with dorso-lateral, short, slender, hyaline projection; projection with long curled hairs.
