Pseudocrenilabrina Fowler 1934

Pseudocrenilabrina Fowler, 1934 Diagnosis A distinct pseudocrenilabrine clade, the “ Pseudocrenilabrus group ” (Weiss et al. 2015, Schedel et al. 2019) is united by molecular characters discovered through analyses of both mitochondrial and nuclear DNA (Schedel et al. 2020). A single morphological synapomorphy further unites all members of the genera Pseudocrenilabrus, Lufubuchromis and Palaeoplex, namely possession at least in adult males of the “ Pseudocrenilabrus blotch ” (Schedel et al. 2020), a red or orange mark covering the distal tip of the soft anal fin. This fin lacks the ocellated egg-dummies of adult males in the Pseudotropheina and the various non-ocellated coloured spots or streaks of adult males in the Cyrtocarina and Rhamphochromina. Type genus: Pseudocrenilabrus Fowler, 1934 Included genera and additional species as indicated by mitochondrial DNA data (Schedel et al. 2019): Lufubuchromis Schedel, Kupriyanov, Katongo & Schliewen, 2020; Palaeoplex Schedel, Kupriyanov, Katongo & Schliewen, 2020; and Pseudocrenilabrus Fowler, 1934; also Haplochromis moeruensis (Boulenger, 1899); Orthochromis machadoi (Poll, 1967); and four northern Zambian species of Orthochromis: O. kalungwishiensis (Greenwood & Kullander, 1994); O. luongoensis (Greenwood & Kullander, 1994); O. katumbii Schedel, Vreven, Manda, Abwe, Manda, & Schliewen, 2018; and O. mporokoso Schedel, Vreven, Manda, Abwe, Manda, & Schliewen, 2018. Distribution Widespread (Pseudocrenilabrus spp.) in northern, central, eastern and southern Africa; other species in northern Zambia, Lake Mweru and Angola (Cunene River). Notes Fowler (1934): 462 proposed the subfamily name Pseudocrenilabrinae, whose stem Pseudocrenilabr- is therefore available for use in other family-group names, including subtribe, taking the same authorship and date. Tawil (2001) mentioned a tribe Pseudocrenilabrini and a subtribe Pseudocrenilabrina, without citing their author and date. Vertebral and pterygiophore counts and most-frequent insertion patterns of the latter, are summarised in Tables 1, 2, but are not distinctive for this subtribe.
