is not particularly similar to any other species. Specimens are elongate and posteriorly attenuate (Fig. 18A). The dorsal surface is vaguely fasciate with variegations of yellow, brown and dark brown (Fig. 18A). The lateral elytral carina is elongate, extending about 1/2 length of the elytron (Fig. 18B). The prosternal process has distinctive lateral lobes anteriorly and is posteriorly abruptly narrowed (Fig. 18C). The metaventrite carinae are distinctive, extending across the metaventrite (Fig. 18C). They are slightly constricted anteriorly and moderately divergent posteriorly (Fig. 18C).

Prosternum medially rounded and setose; prosternal process relatively slender, widest at anterior laterally expanded lobes, posteriorly abruptly narrowed, then margins subparallel to rounded apex, lateral margins strongly carinate, longitudinally strongly excavated (Fig. 18C).

Legs with surfaces covered with fine punctation; pro- and mesotibiae moderately broad; metatrochanter strongly offset and apically rounded; metatibia with posteroapical brush of setae; metacoxa covered with fine punctation; metacoxal lines approximated, parallel (Fig. 18C). Abdominal ventrites covered with fine punctation; VI apically broadly rounded.

<paragraph pageId="33" pageNumber="78">The type specimen had been dissected for examination in this study, and the base of the male median lobe and the lateral lobes were damaged and could not be illustrated. Other than the male type specimen, only two female specimens are known for this species, they are very similar to each other and distinct from all other species. They were also collected quite some distance from each other. Despite the lack of knowledge of males, it seems likely that future association of specimens with this species will not be problematic.</paragraph>
