Camponotus (Tanaemyrmex) nubis Weber new status

return to key {link to the Hymenoptera Name Server} Type location South Sudan (Camponotus (Myrmoturba) maculatus (Fabr.) nubis, subsp. nov., Weber, 1943c: 385, illustrated, major & minor workers; synonymized with C. maculatus by Baroni Urbani, 1972: 129); collected by N A Weber, Imatong Mountains, elev 5700', 28.vii.39, No. 1351.


{Camponotus maculatus nubise}Weber's (1943c) description is at {original description}.
Major TL 9.7 mm, Minor TL 6.4 mm; no mention of any light patches. Baroni Urbani (1972: 129) appears not to have sighted the Weber type specimen but synonymized it with maculatus as a simple chromatic variety close to melanocnemis not with any obvious morphological differences. The minor specimen below obviously is fairly distinctive.  The small size strongly suggests this is a distinct species.

{Camponotus nubis minor}The photomontage of a specimen (below) from Sudan, Bentoe, South Sudan Province, collected by Awatif Omer, 2006, Sudan 13; exactly matches the alitrunk profile drawn by Weber, and has very similar characters and colour. 


{Camponotus maculatus sudanicus}
Collated illustration (right) is of a cotype of Camponotus maculatus ssp sudanicus (Weber, 1943c: 385, soldier & worker; synonymy with C. maculatus by Baroni Urbani 1972: 125) from Southern Sudan. The original photographs, together with enlarged images, are from the MCZ, Harvard University, website at - MCZ link. Weber's (1943c) description of sudanicus is at {original description}. Major TL 9.1 mm (AL 3.3 mm) body dark brown almost black; smaller than melanocnemis; darker than aegyptiacus and without spots; nest arboreal. This does not seem to be any different to nubis see above. However, nubis was found nesting in the black montane humus under stones and among grass roots, whereas the single nest of sudanicus was in the stub of a tree branch. Despite describing both, Weber makes no reciprocal comparisons.
