Patellapis (Patellapis) impunctata sp. n. Timmermann

( Figs. 16a–g )

Diagnosis. The female is characterised by the shiny and completely unpunctate margins of T1–T3. In combination with the weakly convex, shiny, and extensively unpunctate scutellum the female of P. impunctata can be easily identify from all other species belonging to this species-group. The male of P. impunctata is unknown.

Face shiny and with loose, long, greyish to yellowish, erect hairs. Mandibles bidentate. Clypeus and supraclypeal area convex in profile. Clypeus strongly and moderately densely punctate (i = 1,0–1,5d). Clypeoantennal distance 0,4mm. Supraclypeal area strongly and densely punctate (i = d), except lower part extensively unpunctate.

Scutum shiny; disc strongly and densely punctate (i = d); surface partly chagreened anteriorly ( Fig. 16b ). Scutellum weakly convex, shiny and with extensively unpunctate areas laterally ( Fig. 16c ). Scutum, scutellum, metanotum, mesepisternum and propodeum with yellowish, erect hairs.
