Camponotus (Paramyrmamblys) prosulcatus Santschi

return to key {link to the Hymenoptera Name Server} Type locality Zare (Camponotus (Paramyrmamblys) prosulcatus n. sp., Santschi, 1935a: 284, illustrated, major worker) collected at Tua, by Dr J. Maes, 6.vi.1913, holotype major worker .


{Camponotus prosulcatus}Santschi's (1935a) description is at {original description}.
MAJOR WORKER - TL 6.5 mm; HL 2.3, HW 1.6; posterior tibia 1.5 mm. Head rectangular, obliquely truncate anteriorly; almost one-third longer than wide; sides parallel, dorsal border straight; posterior angles shortly rounded. Eyes almost flat, oval, a little larger than one-fifth the face; situated in the posterior third. Mandibles robust and very arcuate, distinctly punctuate on the sides and with 5-6 teeth. Clypeus feebly convex in front, more strongly behind. Postclypeal notch distinct and deeply impressed. Frontal carinae slightly divergent and a little longer than the greatest distance apart. Genae raised alongside the clypeus, less so posteriorly, with a transverse impresion at level of midpoint of clypeus; with several distinct puncturations. Scape cylindrical, reaching the posterior border of the head. Thorax segments almost equal length and forming a regular curve to the propodeal angle; promesonotal suture clearly impressed. Pronotum longer than wide, a little flattened posteriorly, sides rounded. Propodeum compressed, dorsum narrow, feebly convex and not edged laterally; declivity as long as the dorsum, slightly concave from top to bottom; with a transition angle of 100 to 112. Petiole scale (apparently damaged on one side) narrowed to the rounded summit. First gastral tergite around twice as wide posteriorly as it is long. Femora flattened, tibiae grooved.
Colour blackish, gaster darker; head and pronotum brown-black; mandibles, propodeum, anterior of cheeks and frontal area of face (between carinae), femora and tarsi dull red; pronotum border and funiculi reddish brown; articulations of trochanters yellowish. Overall dull; anterior of head more densely reticulate, puncturate and matt. Gaster finely shagreened and more shiny. Erect pilosity yellowish and very sparse. Cheeks glabrous. Sparse pubescence on appendages.
This Camponotus has a truncation of the head which, although somewhat vague, is as strong as some Asiatic members of the subgenus Colobopsis but the affiliation cannot be judged without seeing the minors.

{Camponotus prosulcatus queen}The photomontage is of a queen collected in Cameroun, SW Province; Mt Kupe; Nyasoso Village; at light; 2.iv.2003, collector D Pryce; OUMNH-2007-042.

This appears to be a close match to the Santschi description of a major worker, allowing for the sexual characters.  Arnold (1924) noted the queen of Camponotus (Paramyrmamblys) ostiarius was generally similar to the major worker but, as with this, slightly larger with a longer head.


{Camponotus prosulcatus male}The photomontage ia of a male collected as above.
