Revalidation and Redescription of 'Lacustricola' chobensis (Fowler, 1935) and Description of a New Miniature Species of 'Lacustricola' from Southern Africa (Cyprinodontiformes: Procatopodidae)

Autor: Denis Tweddle, Albert Chakona, Roger Bills, Pedro H. N. Bragança, Paul H. Skelton

Publikováno v: Ichthyology & Herpetology. 109

The “Lacustricola” hutereaui species complex is herein defined by the possession of banded dorsal, anal, and caudal fins in males and also by the pointed premaxilla ascending process, in which the premaxilla medial surface is slightly convex. “

Re-elevation to species level and redescription of Serranochromis jallae and Serranochromis robustus (Teleostei: Cichlidae)

Autor: Roger Bills, Jay R. Stauffer, Paul H. Skelton, Olaf L. F. Weyl

Serranochromis robustus robustus from Lake Malaŵi and Serranochromis robustus jallae from Zambia were compared using morphological data. We re-elevated S. robustus jallae to species based on the following. Serranochromis robustus generally has a lon
