REMARKS: The phylogenetic analyses of Murienne et al. (2013) and Fernández and Giribet (2015) included material, misidentified as R. feae , from Guinea-Bissau. Comparison with the type specimens of R. feae indicate that these specimens belong to a closely related, undescribed species. Unfortunately, the specimens were carelessly damaged in the process of DNA extraction: legs were removed from the adults and the male copulatory apparatus broken, eliminating or damaging the structures necessary for diagnosis and description. Consequently, the description of this species is postponed until intact material becomes available. The male specimen from the Gambia is unsuitable for description as the sinistral leg III is abnormal and the dextral copulatory apparatus damaged. Although a complete comparison of all the taxonomically informative characters cannot be conducted, given the condition of the few males available, all these specimens are presumed to belong to the same undescribed species. They are also probably conspecific with the specimens reported by Penney et al. (2009) from two other Gambian localities: Abuko Nature Reserve (13°23′28.38″N 16°39′00.18″W) and Bijilo Forest Park (13°26′16″N 16°43′32″W). These specimens, which Penney et al. (2009) regarded as likely belonging to either R. afzelii or R. feae , were not collected, however, and photographs of the habitus of the live animals are the only record available.
