This species is dorsally dark brown with distinctive, irregular fasciae on the elytra (Fig. 16A). The fasciate are somewhat linear-sided making the pale regions subrectangular (Fig. 16A). The lateral elytral carina is absent (Fig. 16B). The prosternal process is elongate and somewhat slender with the lateral margins subparallel (Fig. 16C). The anterior metaventrite process is moderately slender and medially impressed (Fig. 16C). The metaventrite carinae are distinct only anteriorly (Fig. 16C). The male median lobe in lateral aspect has a small basal region (Fig. 16D). The apical portion is evenly curved along the dorsal margin, but thickened subbasally and subapically along the ventral margin (Fig. 16D). The apex is elongate, slender and narrowly rounded apically (Fig. 16D). In ventral aspect the median lobe is slender, bilaterally asymmetrical and apically narrowly and obliquely rounded (Fig. 16E). The lateral lobe is moderately slender and broadly curved to a rounded apex (Fig. 16F). The species is perhaps most similar to

Pronotum subcordate, widest slightly anterior to middle; lateral bead fine; surface shiny with distinctive, moderately dense punctures. Elytra elongate, lateral margins subparallel in anterior 2/3 (Fig. 16A); lateral carina absent (Fig. 16B); surface similar to pronotum. Prosternum medially tectiform and setose; prosternal process elongate, slender, lateral margins subparallel, widest medially, longitudinally impressed, apex rounded (Fig. 16C). Metaventrite with anterior process short, slender, longitudinally impressed, apex narrowly rounded; metaventrite carina present mainly anteriorly along process, closely approximated, absent posteriorly (Fig. 16C); other surfaces sparsely punctate. Legs shiny, relatively impunctate; pro- and mesotibiae moderately broad; metatrochanter distinctly offset, apex rounded; metatibia with posteroapical brush of setae distinctive; metacoxa shiny and sparsely punctate; metacoxal lines broadly separated, anteriorly divergent (Fig. 16C).
