Head (Fig. 1) subspheroidal, not pyriform, dull, granulate, unsetose; occipital carina complete; genal carina absent; POL=4, OL=5, OOL=8, OPL=5, TL=9; greatest breadth of lateral ocellus shorter than POL (2:4); frontal line absent; face with two conical contiguous processes, on which antennae are articulated; frons with complete narrow median longitudinal furrow from anterior ocellus to area between antennal toruli (where there is a keel in the place of a furrow); frontal area between clypeus and conical processes with two almost parallel furrows directed from upper margin of clypeus to conical processes; clypeus with margins rounded; subocular sulcus absent; eye large; head about twice as long as eye (26:13). Palpal formula 2/1 (Figs 4, 5). Pronotum dull, granulate, covered with fine short setae, not crossed by strong transverse impression. Posterior half of pronotum with strong median incomplete longitudinal furrow (Fig. 1). Pronotal tubercles reaching tegulae. Pronotum shorter than mesoscutum (13:23). Mesoscutum and mesoscutellum dull, granulate, covered with fine short setae. Notauli absent. Metanotum short, rugose, transverse. Metapectal-propodeal complex dull, rugose, without transverse or longitudinal keels. Mesopleuron and metapleuron dull, granulate.
