Camponotus (Myrmotrema) carbo Emery

return to key {link to the Hymenoptera Name Server} Type location Eritrea (Camponotus carbo n. sp., Emery, 1877b: 364, illustrated, worker) Sciotel, Beccari - see below
subspecies occidentalis (Camponotus carbo Em. var. occidentalis nov. var., Forel, 1902: 300, major & minor workers) from Ghana, collected at Accra, by R. Buchholz - see http://www.antweb.org/specimenImages.do?code=casent0910466
oldier and worker (see Bolton, 1995) .


{Camponotus (Myrmotrema) carbo}Emery's (1877b) description is at {original description}. Forel's (1902) description of occidentalis is at {original description}. Forel's (1911f) description of osiris is at {original description}.

In his description of osiris (ssp of Camponotus olivieri), Forel (1911f) noted how carbo and Camponotus (Myrmotrema) puberulus, from Ethiopia, were profoundly matt.


Santschi's Key (1915c) separated the species by its having prismatic tibiae and scapes which are flattened but only moderately expanded from base to apex; a rectangular clypeus; and, brown erect hairs. He separated the type and occidentalis on the latter having more distinct pubescence.

Listed from Zaïre by Wheeler (1922); also given as a savannah species in Ivory Coast by Lévieux & Louis (1975). Forel (1911f) reported carbo ssp puberulus from Zaïre, Congo da Lemba by Mayné; note puberulus, first described by Emery (1897e), type location Somalia, was raised to species by Santschi (1915c; see Bolton, 1995).


{Camponotus carbo}In their report of species from Saudi Arabia, with the illustration (right), Collingwood & Agosti (1996), separate it in their key by -
body colour uniformly dark; head with front part with large scattered pits, genae with projecting hairs, whole of head including occiput fringed with short hairs, antennae broadening to apex. In their species notes, they add - clypeus projecting forward, anterior border with broken, bluntly serrated edge, and distinct keel (median carina) which continues posteriorly between the frontal carinae. Head densely sculptured, microreticulate and dull with scattered large punctures towards the genae, across the clypeus and lower frons; also on proximal third of scape which widens from a narrow base to about 1.5 times wider at the apex. Alitrunk dorsum simply arched in lateral profile with distinct mesonotal and metanotal sutures. Petiole a simple scale almost as high as propodeum. Dense sculpturation of head continues over alitrunk, gaster more finely reticulostriate and generally dull. In addition to short erect hairs over the whole head, there are numerous longer hairs on the pronotum, posterior propodeum and dorsum of gaster.

The type description (Emery, 19887b) specifically noted the clypeus is without a median carina and makes no mention of erect hairs on the genae, giving erect hairs as sparse everywhere.  The gaster was given as subtly but densely granulose.  The Saudi Arabian specimen, therefore, seems highly unlikely to have been C. carbo and perhaps is Camponotus (Tanaemyrmex) acvapimensis.
