<paragraph pageId="88" pageNumber="89">Although similar to congeners of the leucoproctum group, this species is readily distinguished from them by the shape of the epandrium, especially the ventral epandrial process that is parallel-sided and has a uniquely shaped apical one-fourth. Subapically, the ventral epandrial process bears a broad and shallowly V-shaped row of tiny setulae. The hypandrium is V-shaped with a moderately well-developed anterior base and a U-shaped, posteromedial, hypandrial emargination. The posterior hypandrial arms are slightly divergent and delicately developed.</paragraph>
