Camponotus (Myrmosericus) eugeniae Forel

return to key {link to the Hymenoptera Name Server} Type location South Africa (Camponotus micans Nyl. r. Eugeniae n. stirps Forel, 1879a: 78, worker; Forel, 1886f: 174, queen; Arnold, 1924: 687, male) - see below
all forms known (see Bolton, 1995) .

subspecies amplior (Camponotus (Myrmosericus) Eugeniae For. r. amplior n. stirps, Forel, 1913b: 341, worker) from Zaïre, Sankisia, also from Old Kasongo, by J. Bequaert - minor see - 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 (comparisons 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.

Forel's (1879a) description is at {original description}. Forel's (1886f) description of the worker & queen is at {original description}. Forel's (1913b) description of amplior is at {original description}. Arnold (1924: 687) provided a translation of Forel's (1879a) description, plus descriptions of the male and queen; this is at {original description}.
