Paratrechina arlesi Bernard

return to key {link to the Hymenoptera Name Server} Type location Guinea (Bernard, 1952: 257, illustrated, worker), from Mt. Nimba, 10 workers from Ravine I of Mount Tô (stations B1,28 and B2.41), 2 workers from Ravine 3 (Lamotte, in Bernard, 1952); cotypes numerous workers from the same places; worker only described (see Bolton, 1995) .

{Paratrechina arlesi}Bernard's (1952) description is at {original description}.

WORKER - TL 2.8-3.1 mm; forebody brown, varying in darkness, gaster blackish, appendages clear brown. All shiny, without puncturation except on the propodeum which is finely puncturated on the dorsum and sides. Strong pilosity, made up of large brown erect hairs, over all the body; pubescence yellowish, fine and sparse.

Placed in subgenus Nylanderia Emery, by Bernard, who regarded it as in a group with other members known from Cameroun to Gabon. The others were P. grisoni Forel (type location Zaïre, with subspecies fuscula Menozzi, from Fernando Po), P. incallida Santschi (type location San Thomé I.), and lepida Santschi; but all three were smaller (TL 2.0-2.4 mm) and had an elongated propodeum, with a smooth propodeum. With arlesi the propodeum was broader than long, very enlarged towards the posterior, with two clear ridges toward the centre. In profile arlesi was steeply declined, being level or only slightly declined in the others. Other than the clear distinctions of the posterior shape of the thorax, arlesi had similar characters to incallida. Bernard dedicated the species to M. C. Arlès, artist from his laboratory who mounted and photographed many of the ants from Nimba.
