39, with small procurved lateral posterior copulatory openings; internal structure typical for members of subgenus Helafricanus, with converging seminal ducts and spermathecae; atria without strong sclerotization (Fig.
51), and the female by the small posterior copulatory openings with seminal ducts converging anteriorly (Figs 54, 55).
Diagnosis: This species can be distinguished from other members of the subgenus by the structure of the copulatory organs: the male palp has a characteristic embolus that is orientated transverse to the longitudinal axis of the palp, while the female differs by the relatively longer seminal ducts.
Initial parts of seminal ducts very weakly sclerotized, membranous (Fig.

Atria depressed with strongly sclerotized circular lips; seminal ducts long, forming three loops, accompanying by large spherical vesicles; accessory glands present (Fig.
Diagnosis: The species may by recognized by the structure of the epigyne, with characteristic spiralling ridges around the copulatory openings and the seminal ducts broader than in other African congeners.

Initial part of seminal ducts tube-shaped, very weakly sclerotized, distal parts forming many loops, accessory glands long, receptacles small (Figs 158, 159).
