Clypeus raised above labrum. Anterior tibia slender and bent at base, dilated with bifid or trifid apico-lateral armature. Description The description below is based on the holotype and points out, where necessary, the differences shown by the fragments. Male. Head broad and short, angularly oblong, anterior angle of gena only slightly obtuse-angled, narrow, anterior margin not indented or emarginate near lateral angle. Anterior margin evenly sinuate in middle. Disc rather sharply raised at inner margin of eye, moderately depressed anteriorly in middle, with a pair of round and indistinct elevations at either side of depression. Punctation consists of rather uniform, moderately large, well-spaced punctures in the middle; integu- ment densely shagreened. Mandibles short and stout, bent more or less at a right angle; dorsal process near base conical; in the fragments less forward-pointing (as figured). Ventral process very broad, with inner corner roundly produced anteriorly, reaching about two-thirds of mandibular length (Fig. 24B). Labrum flat and pointedly triangular, clypeus sharply elevated above its base. Mentum large and flat, oblong, anterior margin truncate. Pregular sulcus evenly concave, not sharply Fig. 26.
