Dorylus (Dorylus) striatidens Santschi

return to key {link to the Hymenoptera Name Server} Type location Senegal (Dorylus striatidens n. sp., Santschi, 1910g: 745, illustrated, worker) collected at Casamance, by Claveau
worker only known (see Bolton, 1995). .

{Dorylus (D.) striatidens}Santschi's (1910g) description is at {original description}.

As Santschi suspected, this appears to embody two species, with the larger Dakar form being separated from the true Casamance form. The latter appears to be matched by the specimens I drew from CRIN, Nigeria, and the Cameroun and Central African Republic workers (bottom). What Santschi denoted as a media would appear to be the major worker of the true striatidens.

With fresh specimens from Senegal, I believe the Dakar form specimens were examples of Dorylus aegyptiacus, i.e. a savannah or desert species.

D. striatidens appears to be a woodland or forest species.

{Dorylus (Dorylus) species a}

Nigeria specimen (as Dorylus (Dorylus) species A, Taylor, 1980b: 17). WORKER. TL 5.57-2.83 mm. At least four morphs; largest HL 1.49, HW 1.37, SL 0.59, PW 0.78
Colour yellow-brown, apices darker. Sculpturation of scattered small hair-pits on dorsal surfaces; lateral alitrunk very finely reticulostriate, lateral petiole finely reticulate. Erect hairs sparse, on clypeal margin and posterior margins of gastral segments; relatively abundant pilosity. Head with slightly convex sides, widest at midlength. Mandibles with three moderate, blunt teeth. Clypeal margin slightly produced medially, frontal carinae highly raised with curious posterior processes. Promesonotum slightly convex. Subpetiolar process flattened with triangular forward pointing apex.
I collected it from leaf litter, dead wood on ground, and a possible nest on a cocoa tree crevice at the Cocoa Research Institute of Nigeria, Idi Ayunre.
