Redescription.

Subadult female (syntype) MNB 13859.

Habitus (Figs 1-4). Measurements: TL ca. 9.0 (abdomen and petiole separated from prosoma), CL 4.36, CW 2.75, CyH 0.35 (0.25 margins), femur I L/W 1.87 (2.27/1.22). Eyes: AME 0.19, ALE 0.13, PLE 0.12, PME 0.10, AME–AME 0.13, AME–ALE 0.22, ALE–PLE 0.84, PLE–PME 0.53, PME–PME 0.40. Colour in alcohol: Carapace, chelicerae and labium medium cherry-red, sternum, maxillae, leg I entirely and abdominal scuta light yellowish-red, other legs pale yellowish-orange, unsclerotised part of abdomen pale yellowish-brown with few small dark brown marks on ventral side near spinnerets. Integument of carapace very moderately rugose on dorsal side of cephalic portion but more coarsely rugose laterally and in thoracic part, abdomen uniformly covered with dense fine microsetae mixed with less numerous longer and stouter setae. Legs: Leg formula 1423. Tibia I unarmed, but metatarsus I ventrally with ca. 15 small rod-like teeth. True undivided scopula on entire ventral surface of tibia I; long, entire and prolateral on metatarsus and tarsus I, widely divided by setae on tarsi II and III, vestigial on tarsus IV. Metatarsi II–IV with ventral brushes of dense setae. PTC each with 3-5 tiny low teeth.

Leg measurements:

Abdomen: abdominal scuta very transparent and weakly pigmented. Dorsal scutum (Ds) hexagonal, not fused with epigastral one, wider than long, spaced from epigastral scutum by 1/3 of maximal width; epigastral scutum with shallow concavity, postgastrum with one stripe-like scutum (Ps) fused with epigastral one near lateral margin of book-lung slit. Petiolar tube very short without transversal wrinkles. Whether the described structures entirely correspond to those of the conspecific adult females, or not, is currently uncertain.

Copulatory organs: undeveloped (Fig. 5).

Male.

The current depository of the male syntype was not located (most probably, it was placed by Simon in the MNHN) and this specimen has thus not been examined.

Types.

Syntypes ♀ subad., 2 juvs, SOUTH AFRICA: Northern Cape Province, Komaggas (original “Kammagas”; 29°48'S, 17°30'E), vii.1904, L. Schultze (MNB 13859). Syntype ♂, same data (MNHN, not examined).

Distribution.

Known from South Africa (WSC 2019) and Namibia (Griffin & Dippenaar-Schoeman 1991).
