Vertex with engraved, weak reticulation ( Fig. 16 ). Occipital margin rounded. Eyes with sparse, scattered hairs ( Figs 14– 16 ). Pronotum without transverse carina close to posterior margin ( Fig. 17 ). Mesoscutum with raised, strong reticulation ( Fig. 17 ); notauli as narrow distinct grooves in anterior 1/3, not visible in posterior 2/3.
