Reproductive system: The penis is proximally slender and subcylindrical, constricted at the base; median part is swollen, pear-shaped, tapering towards the distal part which is subcylindrical again. Transition to the epiphallus with a kink, thereafter gradually tapering; twisted. Vas deferens is adhering to and partially inside the penial complex. Flagellum has ca. 1/5 the total length of the penial complex. Internal structure of penial complex is with longitudinal folds in proximal part of penis, changing into a dense tubular network and a widened lumen in the distal part of the penis. The epiphallus has 3-4 longitudinal folds proximally, transversing into anatosmosing folds more distally. In the specimen dissected, a chitinous spermatophore was being formed with the shape of flagellum and epiphallus, its initial stage inside the flagellum and extending to the distal part of the penis.[2]
