The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • cocosensis. Camponotus (Myrmamblys) cocosensis Wheeler, W.M. 1919d: 305 (s.w.) AUSTRALIA (Cocos Is). Wheeler, W.M. 1933a: 61 (q.m.). Combination in C. (Myrmaphaenus): Emery, 1925b: 155.

Description

Queen

Wheeler (1933) - 11-12 mm. and resembles the worker major, but the head is less narrowed anteriorly and the antennal scapes are longer. Thorax elongate-elliptical, slightly broader than the head; mesonotum as long as broad; base of epinotum convex, decidedly shorter than the subperpendicular, concave declivity. Superior border of petiolar node rather deeply and semicircularly excised. Surface of head and thorax much smoother and more shining than in the worker. Erect hairs on the head and thorax shorter and sparser. Head and appendages reddish yellow; thorax and petiole deep red. Wings long (12 mm.), yellow, with somewhat darker resin yellow veins and pterostigma.

Male

Wheeler (1933) - 6.5-7 mm. Head through the eyes very nearly as wide as long; cheeks straight; clypeus bluntly carinate; mandibles triangular, with well-developed but edentate apical border; eyes and ocelli large and prominent; antennre long and slender. Thorax stout, with large mesonotum, much broader than the head; epinotum short and convex, with subequal base and declivity. Petiolar node low and thick, its obtuse superior border broadly impressed in the middle. Legs long and slender. Pilosity pale, sparse and of uneven length as in the female. Head and thorax subopaque as in the worker; scutellum and epinotum smoother and more Shining. Head, genitalia, appendages and sutures of thorax brownish or reddish yellow; remainder of thorax dark brown; gaster black. Wings yellow as in the female but both membranes and veins distinctly paler.
