Camponotus (Tanaemyrmex) negus Forel - new status

return to key {link to the Hymenoptera Name Server} Type locality Ethiopia (Camponotus maculatus F. subsp. negus n. subsp., Forel, 1907c: 142, all forms; subspecies of thraso according to Emery, 1920c: 6) Kounhi - see below
subspecies
agricola (Camponotus maculatus subsp. Agricola, Forel 1910e: 454, major & minor workers) South Africa, Natal, Wroughton  - see http://www.antweb.org/specimenImages.do?code=casent0910118
unavailable names
assabensis (C. maculatus ssp adenensis var assabensis, Emery, 1893f: 258, worker) Eritrea - see http://www.antweb.org/specimenImages.do?code=casent0905282
beritchi (Camponotus (Myrmoturba) maculatus F. r. negus For. v. Beritchi n. v., Forel, 1915c: 348, worker) South Africa, George, Cape Province, H Brauns - no images on Antweb (October 2014)
etiennei (Camponotus maculatus subsp. negus Forel var. Etiennei n. var. Forel, 1910e: 453, major & minor workers) Zare, Banana, Dr Etienne - see http://www.antweb.org/specimenImages.do?code=casent0910126
all forms described (see Bolton, 1995) .

The type locality of thraso is Sri Lanka and subspecies range across to Israel; it seems unlikely that negus would be a subspecies with a range the length of eastern Africa, so I have taken negus as a full species. I am also including:
montinanus (Camponotus (Myrmoturba) thraso var montinanus, Santschi, 1926b: 251, major & minor workers, from Zimbabwe - see below
and nefassitensis (Camponotus maculatus subsp. negus Forel var. nefassiensis n. var., Forel, 1910c: 266; Menozzi, 1931a: 155, major & minor workers, name and distribution only) from Ethiopia, Nefassit - see below (also from Eritrea, Finzi, 1939a: 160) as probable subspecies.

Note tacitus (Camponotus maculatus race agricola, Forel var. tacitus, Santschi, 1919b: 240, major & minor workers) South Africa, Natal, Haviland - see http://www.antweb.org/specimenImages.do?code=casent0912069 is a light red-brown form and probably is unrelated to negus.


Forel's (1907c) description is at {original description}; his (1910e) description of agricola is at {original description}; his (1910e) description of etiennei is at {original description}; his (1910c) description of nefassitensis is at {original description}; and his (1915c) description of beritchi is at {original description}. Arnold's (1922: 648) translation, as maculatus race negus variety beritschi, is at {original description} and his (1922: 647) translation, as maculatus race agricola, is at {original description}. Santschi's (1926b) description of montinanus is at {original description}. Arnold's (1926: 293) translation of tacitus, is at {original description}

Emery (1893f) simply noted on assabensis that a worker specimen from Assab differed from adenensis in having the gaster without striolate sculpture but being irregularly transversely reticulo-punctate.
