Patellapis (Chaetalictus) calviniensis ( Cockerell 1934) View in CoL

Halictus calviniensis Cockerell, 1934: 115–116 .

( Figs. 111a–g View FIGURE 111 ; 112a–f View FIGURE 112 )

Diagnosis. The male is characterised by lacking bristles on the posterior margin of S4. Further, the male has distinct formed dense, fan–shaped hair patches on metasomal sterna S4–S5. The female is morphologically characterised by a coarsely wrinkled basal area of propodeum and a strongly sculptured and densely punctate propodeum. The female resemble those belonging to the subgenus Patellapis (e.g. P. reticulata or P. karooensis ).

Integument black except mandibles and malar area usually partly reddish-brown. Face shiny and with loose, long, greyish and yellowish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus and supraclypeal area sparsely punctate; surface polished; clypeus sometimes with median depression. Clypeoantennal distance 0,4mm.
