description: Patellapis (Chaetalictus) timpageleri sp. n. Timmermann   
(Figs. 108a–g; 109a–h)  
 Diagnosis. The male differs from those of P. sakagamii and P. pulchrinitens in having the clypeus and supraclypeal area densely punctate, whereas P. sakagamii and P. pulchrinitens have a highly polished face with well separated fine punctures on clypeus and supraclypeal area. The male of P. renosterveldi differs from P. timpageleri in the scutal surface, which is completely reticulate in P. renosterveldi and at most partly reticulate anteriorly in P. timpageleri. The male of P. minima is clearly separated from all other species of this species-group in having no hairs on the dorso-lateral projection of the gonostylus. The male of P. spinulosa can be distinguished from that of P. timpageleri by having the scutal surface more sparsely punctate (i= 2,0d) than in P. timpageleri (i= 1,5d). The female of P. timpageleri is similar to that of P. spinulosa. Both can be distinguished by the punctation of the scutum, which is more densely punctate in P. timpageleri (i= 1,5d) than in P. spinulosa (i= 2,0d). Females of all other species belonging to this species-group differ from P. timpageleri in having the scutum completely reticulate.   
 Description   
 Female. Bl = 4,4–4,8mm. General habitus (Fig. 108e). Head. L = 1,3–1,4mm; W = 1,5–1,6mm. Head slightly wider than long (Fig. 108a). Integument black except mandibles sometimes partly reddish-brown. Face shiny and with loose, greyish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus strongly and sparsely punctate; surface shiny. Clypeoantennal distance 0,3mm. Supraclypeal area with well separated minute punctures; surface sometimes finely chagreened. Paraocular area moderately strongly and densely punctate; surface partly sculptured. Antennae brownish-black. Mesosoma. L = 0,9–1,0mm; W (ITS) = 1,1–1,2mm. Integument black. Scutum shiny; surface often finely chagreened anteriorly; disc strongly and moderately densely punctate (i = 1,5d) (Fig. 108b). Scutellum as illustrated in Fig. 108c. Scutum, scutellum, metanotum, mesepisternum and propodeum with long, greyish to pallid yellowish, erect hairs. Basal area of propodeum as illustrated in Fig. 108c; propodeum slightly dull, with well separated minute punctures; surface completely sculptured. Marginal region of posterior truncation slightly dull; variable structure of surface, but often reticulate. Wings. Hyaline. Legs. Integument brownish-black. Vestiture greyish to yellowish. Ts finely serrate (Fig. 108f). Bp slender; angulated apically (Fig. 108g).   
 Metasoma. L = 2,6–2,7mm; W = 1,6–1,7mm. Integument black except the margins of T pallid brownish and pallid yellowish (usually T1–T3); margins partly translucent. Apical hair bands on metasomal terga absent (sometimes they are weakly present on T3–T4). Prepygidial fimbria mostly yellowish-brown. Metasomal terga as illustrated in Fig. 108d.   
 Male. Bl = 4,4–4,9mm. General habitus (Fig. 109f). Head. L = 1,3–1,5mm; W = 1,3–1,4mm. Head about as wide as long (Fig. 109a). Integument black except mandibles sometimes partly reddish-brown. Clypeus, supraclypeal area, paraocular area and vertex covered with erect, greyish hairs; paraocular area, supraclypeal area and clypeus also covered with appressed, whitish hairs. Mandibles simple. Antennae brownish-black. Flagellomeres of normal structure, not knotty. A4 about as long as A3. Mesosoma. L = 0,8–0,9mm; W (ITS) = 1,0– 1,1mm. Integument black. Scutum shiny; strongly and moderately densely punctate (i = 1,5d); surface slightly chagreened anteriorly (Fig. 109b). Scutellum as illustrated in Fig. 109c. Scutum, scutellum,metanotum, mesepisternum and propodeum with long, greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 109c; propodeum slightly dull, strongly and densely punctate; surface coarsely sculptured. Marginal region of posterior truncation slightly dull; variable in structure, but often coarsely sculptured. Wings. Hyaline. Legs. Integument brownish-black. Vestiture greyish. Metasoma.
