Type material: Lectotype 3, designated here ( MNHN, #20204) Zululand / C. M. [= Republic of South Africa, KwaZulu-Natal, exact locality and date unknown (C. Martin)].

Paralectotypes: 33, 14Ƥ ( MNHN, #20204) together with lectotype.

Diagnosis. This species differs from other Baryphas species in the shape of the tibial apophysis which is relatively short, with apical teeth, and the absence of a clearly visible basal bulb on palpal tegulum ( Figs 2–4 View FIGURES 2 – 10 ).

Abdominal pattern with white or orange transverse stripes and a central patch ( Figs 15–16 View FIGURES 11 – 17 ). Structure of epigyne and spermathecae as in Figs 8–10 View FIGURES 2 – 10 .

Distribution. Republic of South Africa, Zimbabwe.

Comments. Baryphas ahenus is the type species of Baryphas Simon, 1902 , which includes four species (Platnick 2013) that are common in South Africa and Zimbabwe. Simon did not designate a holotype and a lectotype is designated here because Baryphas ahenus varies considerably in size and coloration and we wanted to avoid any nomenclature confusion. Simon, based on his observations of this body size variation, labelled type specimens as Baryphas ahenus and non-type specimens as Baryphas ahenus major ( Figs 6–7 View FIGURES 2 – 10 ). However, despite this considerable body size variation (2×) in males, the size of the bulbus is almost identical ( Figs 2–3 View FIGURES 2 – 10 ). Coloration of patterns on dorsal side of abdomen in females is also very variable – with stripes and a central patch formed by white or orange scales ( Figs 15–16 View FIGURES 11 – 17 ). Females vary slightly in size, but epigynes are very variable within populations ( Figs 8–9 View FIGURES 2 – 10 ).
