Patellapis (Chaetalictus) paulyi sp. n. Timmermann

( Figs. 123a–g )

Diagnosis. The small, black bee P. friesei is characterised by its elongate face, which also occurs in related species like P. stoeberia and P. friesei . The female differs from those of P. stoeberia in having the basal area of propodeum coarsely wrinkled, whereas this area is extensively reticulate in P. stoeberia . P. paulyi differs from P. friesei in the punctation of the paraocular area and the discs of T1–T2, which are more densely punctate than in P. friesei . Further, the scutum of P. friesei is extensively reticulate, whereas at most finely reticulate anteriorly in P. paulyi . The male is unknown.

Description

Female. Bl = 6,0– 6,1mm. General habitus ( Fig. 123e ). Head. L = 1,8–1,9mm; W = 1,6–1,8mm. Head slightly longer than wide ( Fig. 123a ). Integument black except mandibles and malar area partly reddishbrown. Face shiny and with loose, greyish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus finely and sparsely punctate; surface polished. Clypeoantennal distance 0,5mm. Supraclypeal area with a few well separated punctures; surface polished. Paraocular area sparsely punctate; surface shiny; partly sculptured. Antennae brownish-black. Mesosoma. L = 1,1–1,3mm; W (ITS) = 1,3–1,5mm. Integument black. Scutum shiny; surface finely reticulate anteriroly; disc densely punctate (i = 1,0d) ( Fig. 123b ). Scutellum as illustrated in Fig. 123c . Scutum, scutellum, metanotum, mesepisternum and propodeum with greyish, erect hairs. Basal area of propodeum as illustrated in Fig. 123c ; propodeum and marginal region of posterior truncation slightly shiny; finely and completely reticulate. Wings. Hyaline. Legs. Integument brownish-black. Vestiture mostly greyish. Ts moderately strongly serrate with 6–7 oblique projections ( Fig. 123f ). Bp as illustrated ( Fig. 123g ). Metasoma. L = 3,1–3,3mm; W = 2,0– 2,1mm. Integument brownish-black; margins of T pallid brownish to pale, broadly translucent. Weak apical hair bands on T3–T4 (usually only present laterally). Prepygidial fimbria mostly brownish. Metasomal terga as illustrated in Fig. 123d .

Male. Unknown.
