The genus PseudocorinnaSimon, 1910 is revised. The type species Pseudocorinna rutilaSimon, 1910 from Guinea-Bissau and Pseudocorinna septemaculeataSimon, 1910 from Bioko are redescribed. No material could be found of Pseudocorinna graciliorSimon, 1910 from Bioko which is to be considered nomen dubium. The genus further contains 27 species which are described as new: Pseudocorinna alligator, Pseudocorinna amicorum, Pseudocorinna amphibia, Pseudocorinna banco, Pseudocorinna bilobata, Pseudocorinna brianeno, Pseudocorinna celisi, Pseudocorinna christae, Pseudocorinna cymarum, Pseudocorinna doutreleponti, Pseudocorinna eruca, Pseudocorinna evertsi, Pseudocorinna febe, Pseudocorinna felix, Pseudocorinna gevaertsi, Pseudocorinna incisa, Pseudocorinna juakalyi, Pseudocorinna lanius, Pseudocorinna lobelia, Pseudocorinna natalis, Pseudocorinna naufraga, Pseudocorinna okupe, Pseudocorinna orientalis, Pseudocorinna perplexa, Pseudocorinna personata, Pseudocorinna ubicki, and Pseudocorinna victoria. The genus is characterized by the wide carapace and sternum and the dense network of dark warts on all sclerites of the prosoma. These structures are apparently outlets of underlying glands producing a gel-like substance. The genus is restricted to the West and Central African forest area, ranging from Guinea-Bissau to the eastern Democratic Republic of Congo. The species are mainly found in very wet, temporarily inundated forests. A cladistic analysis strongly supported the erection of a new, closely related genus, Crinopseudoa gen. nov., with very similar habitus but with poorly developed warts that have kept their original hair-socket function. This genus contains 11 species, all of which are new, and has a distribution restricted to the West-African refuge areas around Liberia and Cameroon. The type species is Crinopseudoa bong from Liberia. It further contains Crinopseudoa billeni, Crinopseudoa bongella, Crinopseudoa caligula, Crinopseudoa catharinae, Crinopseudoa ephialtes, Crinopseudoa flomoi, Crinopseudoa leiothorax, Crinopseudoa otus, Crinopseudoa paucigranulata, and Crinopseudoa titan. Both genera can be regarded as examples of successful somatic templates with a large range of morphologically different genitalia corroborating the ‘mate check’ hypothesis. Illustrated keys to the species of both genera are provided.
