At the end of the 19th century G. A. Fischer collected fishes in East Africa, more precisely in the modern countries Tanzania and Kenya. These fishes were the first specimens known to ichthyologists from some parts of these countries (e.g. from Lake Natron, Lake Victoria drainages). In this context the type localities and the status of Fischer's material are of special importance. Although modern ichthyologists working on East African fishes have been of the opinion that those localities are unknown this is not the case and the itineraries of Fischer are well‐documented. In this paper the types of Fischer's collections are redescribed and discussed, especially the Lake Victoria haplochromines, most of which were considered as lost. Two of these, Chromis nuchisquamulatus Hilgendorf, 1888 and Ctenochromis sauvagei Pfeffer, 1896, do not represent the biological species as previously believed, and two genera (Xystichromis and Ptyochromis) based by Greenwood (1980) on these taxa, are therefore of doubtful status. The taxonomic or biological species previously mistaken for Ctenochromis sauvagei Pfeffer, 1896, the nominal type of which was also collected by Fischer, is described as Haplochromis (Ptyochromis) fischeri spec. nov. The holotype of Ctenochromis sauvagei in fact corresponds to a species known as H. spec. “rockkribensis”. Because Ctenochromis sauvagei is the type species of Ptyochromis Greenwood, 1980 and because the holotype of this nominal species is different from the taxonomic species and actually belongs to Paralabidochromis Greenwood, 1956, according to article 70.3.2 of I.C.Z.N. the biological species H. (Ptyochromis) fischeri was chosen from the two species in question and designated the type species for the genus group Ptyochromis Greenwood, 1980, in order to retain the genus group Ptyochromis unchanged.

Neolamprologus devosi sp. n., a new species of riverine lamprologine cichlid is described from the lower Malagarasi River, Tanzania. The new species is tentatively placed within the poorly defined genus Neolamprologus, though generic reassignment may be necessary once ongoing work on the phylo-geny and classification of lamprologines is completed. Notably, Neolamprologus devosi sp. n. does not present characters diagnostic of Congo (ex-Zaire) River lamprologines, and contrary to previous suggestions appears to be phylogenetically distinct from those taxa. This raises questions regarding the number of putative riverine colonizations of lamprologines from a lacustrine source.

Part 1 This paper is the first part of a revision of the type specimens of the Cyprinodontiformes sensu PARENTI (1981) of the ichthyological collection of the Zoological Museum Berlin including most species of the genus Aphyosemion MYERS, 1924 as we understand these species and its synonyms nowadays.
