Patellapis (Chaetalictus) vumbensis (Cockerell 1940)

Halictus vumbensis Cockerell, 1940b: 246 .

Halictus atricillus Cockerell, 1940b: 252 . Syn. n.

The description of H. vumbensis was published on page 246 in part 5 of series 11 of the Annals and Magazine of Natural History. Thus, we give it priority over H. atricillus that was published on page 252 in the same publication.

( Figs. 92a–b )

Diagnosis. The female is unknown. The male is characterised by a sparse row of 8 long, erect bristles on posterior margin of S4 and by a long and slender, hairy (a few curled hairs), dorso-lateral projection on the gonostylus.
