Cerapachys cribrinodis (Emery)

return to key {link to the Hymenoptera Name Server} Type locality Cameroun (Parasyscia cribrinodis n. sp., Emery, 1899e: 463, illustrated, worker; combination in Cerapachys, Emery, 1902c: 24) collected at Johann-Albrechtsch÷he, by Conradt; worker described (see Bolton, 1995) .

{Cerapachys cribrinodis}Emery's (1899e) description is at {original description}.

Arnold (1915: 12) included a translation of the original Emery (1899e) description, as follows -
"Worker. TL 3.7 to 4 mm. Blackish brown, shining; the front of the head, mandibles, antennae, tarsi, and apex of abdomen rusty red, last joint of antennae and tarsi ferruginous.
Head a little longer than wide, the sides rounded, as wide in front as behind and widely emarginate posteriorly; the posterior angles sub acute. The eyes large and flat, inserted in about the middle of the sides of the head; the frontal carinae fused with the clypeus, forming on each side a projecting lobe, itself bilobed anteriorly. The antennae are therefore placed farther forwards than in other species of the genus; the frontal carinae are parallel in front, high and close together, but separated by a groove; posteriorly they are fused together and abruptly terminated by a depression continuous with the antennal sockets. The genal carinae are raised anteriorly into a prominence, below which is a depression sufficiently large to accommodate the scape when the latter is directed forwards. Mandibles narrow, their apical margin very oblique, with four small and obtuse teeth at the base, and a larger obtuse tooth in the middle of the basal margin.
Antennae 12-jointed, the scape reaches back to the posterior edge of the eyes. All the joints of the funiculus are broader than long, except the terminal joint which is as long as the four preceding taken together.
The thorax is parallel-sided, depressed dorsally but not marginate and without trace of sutures; the declivity of the propodeum finely marginate.
Head and thorax smooth, sparsely and finely punctured, a hair being inserted in each puncture. The puncturation of the petiole is much coarser, that of the 1st abdominal segment a little smaller, the rest of the abdomen finely punctured. The petiole is half as wide again as long, truncate anteriorly and posteriorly, round above and not marginate; below and in front there is a large rounded projection.
The 1st segment of the gaster is as wide at its base as the posterior edge of the petiole, widening towards the apex ; the 2nd segment is longer than the petiole, but the 2nd and following segments are together shorter than the petiole plus the 1st segment. The legs are hirsute.
Habitat - Cameroons".
Arnold added the type species does not occur in our region (Southern Africa), but I have thought it best to reproduce the original description which applies in the main to the following variety. ". NOTE - The latter variety was natalensis, raised to species by Brown (1975), and from South Africa.

Also from Za´re, 2 workers found in the stomach of a toad (Lang & Chapin; in Wheeler, 1922). Bernard (1952) reported a single finding of 7 workers, from KÚoulenta savanna, Guinea (27.iii.1942, Lamotte); noting that they did not differ from the type of Emery, and although it was a little known insect, it surely existed in all of tropical Africa. Comparative notes can be found under Cerapachys villiersi.
