Head dull, granulated, with a strong median keel between antennal toruli; frontal line complete; face with some transverse keels on sides of frontal line; ocellar triangle almost equilateral; occipital carina incomplete, only present behind and on sides of posterior ocelli, laterally extending beyond 0.5 length of OOL, not reaching eyes; POL = 2; OL = 2.5; OOL = 13; posterior ocelli touching occipital carina; occasionally vertex with two smooth and without sculpture areas situated on sides of posterior ocelli. Palpal formula 6/3. Pronotum ( Fig. 4 ) crossed by a weak anterior transverse impression; posterior surface of pronotum crossed by a further weak transverse impression; anterior collar shiny, without sculpture; disc shiny, sculptured by strong longitudinal keels, occasionally with a median longitudinal furrow; posterior edges of pronotum rounded, not produced into lobes.
