sulcus. Ergatoids have a mesosoma that is usually larger than in true workers but much smaller than in alates. The mesonotum is frequently hypertrophied in ergatoids with respect to the worker caste, and 1-3 ommatidia are usually present, although only a vestigial median ocellus may be remain; there is no transverse sulcus on the mesopleuron. Intermediates between these two extremes exhibit a mesosoma that is alate-like but much smaller in size, usually with most or all sclerites of the pterothorax represented but in a reduced form, fused together, and with no trace of wing attachments; 3 ocelli are always present in these forms. Venation: see under male.

. In addition, the males of three other species, collected in isolation (in Malaise traps), are present in CASC. Similar in size to the conspecific worker or slightly smaller. Mandible triangular and distinctly dentate, with 5-7 teeth. Palp formula 5,3 (in situ counts). Stipital crest present on maxilla. SI 30-52. Antenna with 13 segments, conspicuously not filiform, characteristically modified. First funicular segment short but not globular, about 0.40-0.60 x the length of the second funicular segment. Funiculus segment 8 (= antennal segment 9) about equal in length to the scape. Funiculus segment 9 (= antennal segment 10) strikingly elongate, 1.45-1.80 x SL, and the funiculus with a kink or angle between the elongate ninth segment and the tenth. The three apical funicular segments (10-12) are also elongate and form a slender club, of which at least the apical segment is longer than SL (sometimes 2 or all 3 apical segments are> SL). Eyes large, located at or in front of the midlength of the sides. Ocelli conspicuous. Occipital carina sharp but not forming a raised crest. Mesoscutum in profile strongly overhangs the pronotum, the latter not visible in dorsal view. Mesotibia and metatibia each with a single, simple spur. Notauli variably developed, from vestigial to having anterior arms present. Mesopleuron with a transverse sulcus present. Propodeum usually unarmed and rounded, but in some the posterodorsal angle is reinforced by a carina, or the angle projects as a low, obtuse tooth; propodeal lobes rounded. Petiole in profile slightly longer than postpetiole. Petiole with an anterior peduncle, the spiracle at, or slightly in front of, the midlength of the peduncle, well in front of the level of the low, rounded node. Subpetiolar process minute to absent. Parameres large. Cerci present. Pilosity simple everywhere.

workers are currently diagnosed among the myrmicines only by the presence of a unique combination of characters. As with many other myrmicine genera no unique morphological apomorphy can yet be cited. It is defined by its possession of the following characters in combination: mandible with 6 or more teeth; palp formula 5,3; stipital crest strongly present; antenna 12-segmented, with a 3-segmented club; clypeus with an isolated median seta set above a narrow anterior apron; clypeus posteriorly narrowly inserted between the frontal lobes; frontal carinae present and long, extending almost to the posterior margin of the head; antennal scrobes present; mesosomal dorsal outline simple; petiole pedunculate; first gastral tergite does not overlap the sternite on the ventral surface of the gaster; gastral shoulders absent.
