Camponotus (Tanaemyrmex) abjectus Santschi

return to key {link to the Hymenoptera Name Server} Type location Angola (Camponotus (Myrmoturba) maculatus stirps abjectus n. st., Santschi, 1937d: 240, illustrated, major & minor workers); raised to species by Baroni Urbani (1972: 131); major & minor workers known (see Bolton, 1995) .


{Camponotus (Tanaemyrmex abjectus}Santschi's (1937d) description is at {original description}. Baroni Urbani (1972) in raising it to a full species noted only that it was close to Camponotus pictiventris Mayr - this new status of pictiventris has passed unnoticed by Bolton (1995), where it is listed as a subspecies of Camponotus hova.

As subspecies abjectus Santschi, small and speckled with yellow, recorded from Guinea, by Bernard (1952). It was found, 3 queens and numerous workers, from the savanna at Ziéla and Kéoulenta, crests of Nion (at 1300 m) and Tô (at 1600 m). The fresh specimens below are a close match to the Santschi description and the type major and minor.  The Senegal and South Africa specimens are about 15% larger than the types, although the proportions (CI and SI) appear to be very similar.  There are minor differences in colour pattern, with the South African minor lighter than the Senegal (Bernard) minor.
