Remark:
Halictus patricius Strand 1910: 141, FFF. Holotype FFF: without locality (MNHUB). The female holotype is actually a Zonalictus ! This species is therefore excluded from the genus Thrinchostoma where Blüthgen (1930 : 519, 520, 531, 538) has placed them.

The type of T. malelanum has malar area and clypeus alittle longer. It could be a distinct species, one that Blüthgen had wrongly identified as T. patricium.

Some females from Congo, Cameroon and Gabon have a black metasoma with black setae in the middle of last terga. They represent a variety or a distinct subspecies.
