Så er Haplochromis fischeri videnskabelig beskrevet.

Er der nogen af jer som er i besidelse af PDF filen omkring arten?

Jeg fandt et uddrag på en anden side af den.

Abstract

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.

Jeg prøvede lige via mit uni login, men det pågældende tidsskrift findes ikke blandt dem, jeg har adgang til via det kongelige bibliotek.
Såeh.... Kan desværre ikke hjælpe.
Sig til hvis du evt finder ud af, at den også er udgivet et andet sted.
