Patellapis (Chaetalictus) pulchrinitens ( Cockerell 1942)

Halictus pulchrinitens Cockerell, 1942: 58–59 .

( Figs. 99a–h )

Diagnosis. The male is similar to P. sakagamii . Both species have a highly polished face with well separated fine punctures on clypeus and supraclypeal area. They can be distinguished by the size and structure of S7, which is larger in P. pulchrinitens than in P. sakagamii . Further, the hairs on the dorso-lateral projection of gonostylus are finer and shorter than in P. sakagamii , which comprise only 5 to 6, strong, curled erect hairs. The males of other species belonging to this species-group differ from P. pulchrinitens in having the face more densely punctate (especially clypeus and supraclypeal area) and less shiny. The female of P. pulchrinitens is unknown.
