Paraphallus fused to membranous distal margin of basiphallus. Hypophallus forming broad, flattened V-shaped plate with hairs emerging from base of medial desclerotized region. Mesophallus indistinct. Distiphallus long, tapering to base, more thickly sclerotized along dorsal and lateral walls, with slight segmentation on distal half, and apex thin-walled and enclosing one pair of small spinulose pads. Ejaculatory apodeme with pileus ejaculatorius relatively thin with ends swollen and dark; base of duct dark; base of stem broad and centre of stem and blade weakly sclerotized with minute transverse striations; blade pale with long, irregular base.
