Description

Worker

Rigato (1994) - TL 2.5-2.7, HL 0.65-0.70, HW 0.61-0.65, CI 92-97, SL 0.54-0.59, SI 86-90, PW 0.39-0.44, AL 0.75-0.82, SpL 0.23-0.26, HTL 0.53-0.58, TI 84-89 (10 measured).

With the characters given in the key and the following: Mesonotum in profile with a feeble or faint prominence. Metanotal groove shallow in profile. Propodeal spines in profile straight or slightly curved downward, quite thin and very sharp. Petiolar node in profile high and usually subtruncate.

Clypeus somewhat shagreened and subopaque or sublucid, except for its posteriormost median portion which is smooth. Frontal triangle shining. Head shining, with only a very superficial, quite indistinct, reticulation. Genae with some short rugae. Frontal lobes finely longitudinally irregularly rugulose. Whole dorsum of the alitrunk shining, at most very superficially reticulate. Sides of the alitrunk with few sculptured areas: anterior upper part of mesopleuron and metanotal groove; the rest is smooth with at most a wide-meshed faint reticulation. Petiole and postpetiole chiefly shining and superficially reticulate mostly on the sides. Gaster glassy smooth, shining.

Colour very light brown, head with a reddish tinge.

Queen

Rigato (1994) - TL about 8.5. Propodeal spines stout, straight and quite sharp in lateral view. Clypeus shagreened and subopaque, except for its posteriormost median portion which is smooth. Frontal triangle quite shining. Head finely reticulate, opaque, rugulose chiefly in its anterior half. Scutum and scutellum finely punctulate-reticulate, subopaque. Axillae more densely sculptured, opaque, linked by a narrow strip. Gaster rather lucid.

Colour brown, with a somewhat reddish tinge chiefly on the gaster and on the sides of the alitrunk. Wing nearly hyaline, very feebly yellowish throughout.

Male

Rigato (1994) - TL about 5.5. Mandibles with one apical and one preapical tooth, followed by a fine serration on both masticatory and basal margins. Petiole robust in profile, with a low and evenly rounded node. Clypeus shagreened and sublucid. Head finely reticulate and opaque; some evident oblique rugulae occur at the posterior corners. Scutum finely punctulate-reticulate, sublucid. Scutellum less sculptured and more shining in the middle. Axillae dull, densely reticulate. Sides of the alitrunk more shining. Propodeum about as well sculptured as the scutum and with distinct blunt teeth. Petiole and postpetiole somewhat sublucid. Gaster rather shining.

Colour: head dark brown, alitrunk slightly lighter, petiole, postpetiole and gaster light yellowish brown.

Wings as in female.
