Extract

Allied to pontiaria Tayl. in male genitalia bat the numerous teeth along the chitinized costa of the clasper much smaller; the strong excavation of this section found in pontiaria is much reduced in the present species and the membranous portion of the clasper is subequal in length to that of the chitinzed area and not considerably shorter. The whole genitalia are noticeably smaller.
