has a characterstic coloration with the head and pronotum yellow and the elytra brown with distinct pale yellow maculae and lateral margins (Fig. 33A). The large subbasal macula exends to the lateral margin and, in a narrow subhumeral line, to the anterior margin (Fig. 33A). The apex of the elytron and a distinctive macula at about 3/4 elytral length are also yellow (Fig. 33A). The lateral elytral carina is short and distinctly only near humeral angle (Fig. 33B). The prosternal process is relatively narrow but has distinct laterally-directed lobes anteriorly (Fig. 33C). The metaventral process is narrowly rounded and the metaventrite carinae are indistinct, mainly represented by impunctate lines that diverge somewhat posteriorly (Fig. 33C). The male median lobe is simple and bilaterally symmetrical (Fig. 33E). In lateral aspect the median lobe is basally elongate triangular (Fig. 33D). The apical portion is shallowly curved to a pointed apex (Fig. 33D). In ventral aspect the median lobe is slender and narrowed medially to elongate, slender, pointed apex (Fig. 33E). The lateral lobe is slender and elongate-curved (Fig. 33F).
