Hi,
Some interesting scientific news about the old problem with A. macmasteri and A. viejita.
Unfortunately I guess it takes 30 years again to find its way into peoples minds. ;-)
Taxonomical revision of two colombian species of Apistogramma (Teleostei: Perciformes) with redescription of Apistogramma viejita Kullander, 1979 as Apistogramma unipectomaculata sp. nov.
Orlando Volquete & Franco Avessi
Abstract
Because of the unacceptable taxonomic situation that has developed over the last twenty years in regard to some species of the Apistogramma macmasteri complex, a revision of the colombian species Apistogramma macmasteri Kullander, 1979 from the Rio Meta system and a redescription of the likewise colombian species Apistogramma viejita Kullander, 1979 from the Rio Yucao system are provided. Due to the ongoing misidentifications in nearly all relevant publications (e.g. Staeck 2003; Roemer 1998, 2004; Kullander 1980, 1980a; Koslowski 1985; Mayland & Bork 1989a; Haseman & Meinken 1956 and Hoedeman 1947a) in which A. viejita sensu strictu has erroneously been used as a synonym of A. macmasteri, the use of the taxon A. viejita for the species A. macmasteri has been established itself as a popular and scientific fact. Therefore the taxon A. viejita becomes a nomen nudum and is no longer available as a valid species name. Nomenclaturically the taxon is transduced to a junior synonym of A. macmasteri according to the rules of ICZN.
Thus the taxon A. viejita is given the status of a valid (permitted for use) synonym of A. macmasteri. The species, so far defined as Apistogramma viejita sensu Kullander, 1979, is redescribed as the 88th taxon of the genus, Apistogramma unipectomaculata sp. nov., based on 27 specimen, which include the two inadequately preserved specimen from the type series of A. viejita. The former holotype of A. viejita (NRM 11231, ♂30.1 mm SL) now achieves the status of a neoparatype and a new holotype is defined (MZUB 42124, gend. unk., 18.2 mm SL).
