(Cape Peninsula or “Clade A”, McDonald & Daniels 2012)

Bouvier (1907) ascertained that the type material of P. capensis (Grube, 1866)  is lost. Consequently, Ruhberg (1985) established a neotype to stabilize the taxon (Article 75, ICZN).

Neotype. Rhodes Memorial, Table Mountain, Cape Peninsula, Western Cape province, South Africa: 1 M collected 1975 by S. and M. Kiselowa. See Ruhberg (1985: 94) for full description ( ZMHAbout ZMH A 25 / 80).

In the combined DNAAbout DNA sequence topology ( Fig. 1View FIGURE 1) P. capensis sensu  stricto formed a genetically distinct and statistically well-supported monophyletic clade ( McDonald & Daniels 2012). Peripatopsis capensis  is now restricted to Clade A.

Description. Colour and patterning: Dark brown/slate black/indigo and seldom rust orange pigmentation. Dark dorsal midline with light lateral band above legs along the entire body (table 1).

Legs: 17 + 1 leg pairs. Dorsal foot ridges absent. Three complete spinous pads with the fourth being completely fragmented (table 1).

Integument: Densely spaced primary dermal papillae with relatively large accessory papillae ( Fig. 3View FIGURE 3 c; table 1), cylindrical or dome-shaped primary dermal papillae with 6–9 scale ranks ( Fig. 4View FIGURE 4 c; table 1). 6–8 rows of chemoreceptors at the antennal tips. Mouth surrounded by 16–17 oral lips.

Male genital area: Gonopore cruciform. Genital pads covered with sensory spines.

Remarks. Peripatopsis capensis  differs from P. l a w re n c e i sp. nov. and P. overbergiensis  sp. nov. in the structure of the primary dermal papillae as well as in the arrangement of dermal papillae ( Figs. 3View FIGURE 3 & 4View FIGURE 4). Sequence divergence between P. capensis  and the two novel lineages is marked (8.1 % and 8.6 % for P. lawrencei  sp. nov. and P. overbergiensis  sp. nov., respectively).

Habitat. Afromontane forest patches in the southwestern part of the Western Cape province. Collected from inside or under decaying logs, leaf litter, and stones generally close to streams. Specimens were also found within and beneath rotting pine logs in old pine plantations (e.g. Rhodes Memorial).

Distribution. Restricted to the Cape Peninsula, Table Mountain region.
