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.
Epigyne with two rounded depressions, plugged with waxy secretion in numerous specimens; copulatory openings situated prolaterally beneath oblique sclerotized cup-like atria within depressions (Figs 66, 67); internal structure typical for members of the subgenus Helafricanus, with seminal ducts converging anteriorly, with small spermathecae (Fig.
81, seminal ducts very long and narrow, forming several loops; spermathecae narrow and tubiform.
Initial parts of seminal ducts very weakly sclerotized, membranous (Fig.
The species is related to Dendryphantes arboretus Wesolowska & Cumming, 2008 from Zimbabwe; both species have large spherical vesicles near the midpoint of the seminal ducts, which are absent in other Dendryphantes species.
has shorter seminal ducts and long accessory glands.
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).
africanas Peckham & Peckham, 1903, but the seminal ducts are very thin, with large, spherical accessory glands.
