Description

Worker

Minor Differing from the minor worker of the var. isabelensis in having somewhat longer antennal scapes, in the darker red color of the legs and antennae and the more abundant gastric pile, which is like that of the major worker.

Major Differing from the var. isabelensis Wheeler and resembling the var. fernandensis Wheeler in the shape of the head, which has the sides nearly straight and converging anteriorly, instead of convex and rounded. There are no erect hairs on the cheeks as in isabelensis. The mesoepinotal impression is deeper and the superior border of the petiolar scale is sharper and more rounded than in either of these varieties; the pilosity and pubescence on the gaster is longer and somewhat more abundant, the coxae, except at their tips, black.

Type Material

Described from four major workers (V.22.'32) and four minor workers (V.21.'32; V.22.'32) from Iguana Cove, Albemarle Island and six minor workers (IV.28.'32) which are simply labelled "Albemarle," but which, owing to their dark appendages, evidently belong to this variety. There are therefore two varieties of planus isabelensis and hephaestus) on Albemarle Island, just as there are two (indefessus and santacruzensis) on Indefatigable Island. Lectotype, C.A.S., Ent. No. 3690, major worker.
