Anochetus agilis

[6] Anochetus agilis

A. agilis is represented in collections by Emery’s type (MCSN-Genoa), a worker from "Banguey, Borneo". Unfortunately, this example has a shriveled petiolar node, so that the original shape is unknown. A worker specimen taken inland from Batulitjin, Kalimantan Selatan (SE Borneo) in rain forest (W. L. Brown) is larger (TL 11.5, HL 2.37, HW 1.76, ML 1.58, WL 3.60, scape L 2.56, eye L 0.46 mm; Cl 74, MI 67) than the type, and has a blunt petiolar node of a particular form (fig. 41). Forel assigned to A. agilis 2 workers from Sarawak (Haviland); one of these is portrayed in fig. 51. These examples are smaller than Emery’s type: HL 1.64, HW 1.32, ML 1.32, eye L 0.32 mm; Cl 80, MI 80; and have shorter, pointed petiolar nodes.

All 3 of these samples, whether they collectively represent one, two or three different species, are attenuated versions of A. risii that recall in a general way the emarginatus group of tropical America, and A. faurei of southern Africa. The eyes are very large, and the head behind the eyes is narrowed.
