Copa lacustris Strand, 1916: 94 (Ƥ Holotype: D.R. CONGO: Lake Albert, Kassenge [Kasenye, 01°23'N, 30°26'E], Expedition Adolf Friedrichs, Herzogs & Mecklenberg, III.1908, ZMB 28200—examined).
Diagnosis: Males are closely related to C. lesnei sp. nov. but can be recognised by the small embolus with two narrow compressed coils and a blunt tip (Figs 93, 102), with the embolus projecting only slightly beyond the retrolateral margin of the embolus base; in C. lesnei sp. nov. the embolus has a sharp tip and projects considerably beyond the retrolateral margin of the embolus base (compare Figs 102 and 103). Females differ from C. kakamega sp. nov. by the large comma-shaped epigynal ridges (Fig. 126), which are round in C. kakamega sp. nov. (Fig. 118).
Remarks: The material of Castianeira kibonotensis Lessert, 1921 requested from the MNHG comprised only of the two palps of the male type specimen (from Kibonoto, Tanzania), as well as a non-type male specimen from Vila Pery (Mozambique) and a male palp of a non-type specimen from Faradje (D.R. Congo). The Faradje specimen from which the palp originates was presumably deposited in the American Museum of Natural History as the label stated “American Museum Congo Expedition” but it could not be traced in that collection. Unfortunately, the female of C. kibonotensis described by Lessert (1921) could also not be traced. The male from Vila Pery was misidentified by Lessert (1936) as C. kibonotensis, and is a new species, described below as C. lesnei sp. nov. Since the whereabouts of the syntype specimens of C. kibonotensis are unknown, and although only male palps from the male syntype could be located, the male is designated here as the lectotype and the female as the paralectotype. The palps that were studied, as well as Lessert’s (1921) illustrations of the male and female genitalia, provide adequate detail to indicate that this is the male of the widespread Copa lacustris, which is transferred to Copuetta here. Both sexes have been collected together at many localities in southern and eastern Africa. As a result, Castianeira kibonotensis syn. nov. is proposed as a junior synonym of Copuetta lacustris comb. nov. The male palp from Faradje is confirmed as conspecific to C. lacustris comb. nov.

Distribution: Widespread throughout southern Africa, with isolated records from Central and East Africa (Fig. 132).
Biology: This species was collected using a wide range of sampling methods and occupies all strata of the habitats it occupies, from the ground to canopy level. A considerable proportion of the records from South Africa, especially deposited in NMBA and NCA, were sampled in and around human habitation, and this species can be considered to be synanthropic. Egg sacs are large (8–10mm in diameter), yellow-brown in colour, have a covering of papery silk, and are constructed on walls, under window sills or in the folds of curtains.
