Camponotus (Myrmosericus) eugeniae Forel
Type location South
Africa (Camponotus micans Nyl. r. Eugeniae n. stirps
1879a: 78, worker; Forel, 1886f: 174, queen; Arnold, 1924: 687, male) -
all forms known (see
Bolton, 1995) .
subspecies amplior (Camponotus
(Myrmosericus) Eugeniae For. r. amplior n. stirps, Forel, 1913b:
worker) from Zaïre,
Sankisia, also from Old Kasongo, by J. Bequaert - minor see http://www.antweb.org/specimenImages.do?code=casent0910318
- has pale erect hairs and so, clearly is not a form of eugeniae.
I show it below for comparison.
Forel (1879a) described the species as follows
with Camp. micans, type location Algeria) -
TL 8-11 mm; longer; thorax especially major, relatively long; sides of
alitrunk slightly rounded. Mandibles with six teeth; clypeus flat,
carinate, with a slightly shorter lobe, weakly scalloped in centre of
anterior border in major. Petiole scale slim, with convex anterior face
and slightly concave posterior face; wider at the summit, with an
almost straight border.
Sculpturation similar but a more gross, deeper and more irregular
punctate rugo-reticulum. Pilosity on body black (yellowish on micans)
pubescence less abundant, shorter duller of a greyish white (brilliant
yellowish-white in micans). Colour ash black (silky in micans),
matt except for a very narrow posterior yellowish border to gaster
segments; and anterior of mandibles and extremity of tarsi which are
dark reddish black. Legs longer; with flattened tibiae, with decumbent
short black hairs.
Possibly similar also to Camponotus
cinctellus but (at that time) that was inadequately known.
From South Africa, Mission de Valdézia, in Transvaal; and from Lesotho.
Dedicated to Madame Eugénie Berthoud who collected it with her husband.
