Inner sculpture of proximal penial wall has very fine wrinkled, longitudinal penial pilasters, with thick and oblique longitudinal folds in middle, and then transformed to a thin, transverse-folded, surrounded penial verge. Epiphallus slender tube and about two times total penis length. Epiphallic caecum very short; thick penial retractor muscle attached at tip. Flagellum large and irregular slender tube. Vas deferens thin tube. Vagina long and cylindrical tube. Dart apparatus located on vagina away from penis joining to atrium. Spermatophore long and needle-shaped. Tail filament very long tube; region close to sperm sac bearing a very small spine.
