Organ semicapitate and semicalyculate. Capitulum formed by papillate calyces on the sulcate and papillate calyces and body calyces on the asulcate side. Hemipenis with large, calcified lateral spine rows, beginning at the level of bifurcation of sulcus spermaticus and extending along apical portion of hemipenial body, immediately proximal to the beginning of lobes, lateral to asulcate side. Hemipenial body covered with spinules on both sides.
