Notes

Baker (1993: 209) wrote the following:

“ Type material lost or misplaced: there is no specimen now standing above the label ‘ fraternus Sm. ’ in the UMO type collection or above the original drawer-label in Saunders’ collection. [Possibly represented by the metasoma now attached to Nomia modesta Smith, 1862 , q.v., 5.15- 2.] H. fraternus was redescribed by Blüthgen (1926: 480) from supposedly conspecific material from Sandakan and referred to the group ‘Halicti nomioidiformes’, later (1931: 291) treated as a subgenus of Halictus under the name Indohalictus . Indohalictus was synonymized by Michener (1965: 178) with Homalictus ”.

Blüthgen (1926: 480–482) did indeed consider the type material of Halictus fraternus to be lost, and redescribed the species. Revision is required, as Pauly (1980) did not include this species in his revision of Indonesian Homalictus Cockerell, 1919 (treated as a genus), but he later considered it part of this genus without giving a detailed treatment ( Pauly 1986). A new revision would offer the opportunity to designate a neotype to cement the concept of this species.
