convex. Mesonotum barely one-fourth broader than long, sides and front convex, 
posterior edge concave in middle. Epinotum strongly convex in front, almost flat 
laterally; in profile pronotum evenly convex from apex to base. Mesonotum 
evenly convex, highest in front, meso-epinotal suture deep and wide. Epinotum 
evenly arched from base to foot of declivity. Node very slightly broader than long, 
circular; in profile as high as long, anterior and posterior faces short, rounded 
into the convex dorsum, ventral spine short, broad and sharp. Postpetiole one- 
third broader than long, sides strongly convex, constriction deep and wide. First 
segment of gaster much broader than long, broadest behind, sides strongly convex. 
Legs slender. 
Female. Length 14°5-15 mm. 
Colour, sculpture and pilosity similar to that of the worker. Wings hyaline with 
a yellowish tinge, veins brown. 
Head slightly broader than long, sides feebly convex behind, occipital border 
feebly concave, angles broadly rounded. Mandibles shorter than head, external 
border straight, inner border convex, teeth large. Scapes not reaching the occipital 
border by more than their thickness, second segment of funiculus very slightly 
longer than first. Mesonotum with mayrian furrows faintly indicated, parapsidal 
furrows sharply impressed. Node oval, fully one and one-half times broader than 
long. Legs robust. 
Male. Length 12 mm. 
Head, pronotum, mesonotum, scutellum, postpetiole and gaster brownish-black. 
Mandibles, antennae and legs reddish-yellow; sides, epinotum and node yellowish- 
red. Wings hyaline with yellowish tinge. 
Sculpture as in the worker but slightly finer. 
Pilosity similar but longer and slightly more abundant. Head, across the eyes, 
almost one-fifth broader than long, broadly convex behind. Mandibles small, narrow 
and sharp pointed, furnished with three small teeth. Clypeus convex above and in 
front. Frontal carinae as long as broad. Antennae slender. First segment of 
funiculus two and one-half times longer than scape, remaining segments subequal. 
Thorax barely twice as long as broad. Pronotum short, fully four times broader 
than long, strongly convex in all directions. Mesonotum one and one-half times 
broader than long, mayrian and parapsidal furrows strongly impressed. Scutellum 
almost one-third broader than long, convex in all directions. Epinotum convex 
transversely; in profile pronotum convex, high and vertical. Mesonotum high, 
evenly convex from apex to base. Scutellum hemispherical, almost four times 
longer than high. Epinotum evenly convex from base to foot of declivity. Node 
one-sixth broader than long, broadest behind, all faces convex; in profile as high 
as long, anterior face vertical, slightly convex, rounded into dorsum, posterior face 
very short rounded into dorsum ; ventral spine short and sharp. Postpetiole broader 
than long, broadest and strongly convex at basal third; constriction broad and 
shallow. Gaster slender. Legs long and slender.
