Halictus pulchrinitens Cockerell, 1942: 58–59 Variable Selection and Inference for Multi-period Forecasting Problems Timmermann, Kim Kuhlmann, Michael Zootaxa 2009 2009-05-11 2099 1 188 (Cockerell 1942) Cockerell 1942 [151,828,1118,1144] Insecta Halictidae Patellapis Animalia Hymenoptera 140 141 Arthropoda species pulchrinitens Chaetalictus      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. pulchrinitensthan 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. pulchrinitensin having the face more densely punctate (especially clypeus and supraclypeal area) and less shiny. The female of  P. pulchrinitensis unknown.   Description  Female. Unknown.  Male. Bl = 5,7mm. General habitus ( Fig. 99f). Head. L = 1,7mm; W = 1,8mm.
