Seegers, L. (2008): The fishes collected by G. A. Fischer in East Africa in 1883 and 1885/86.
Haplochromis fischeri Seegers, 2008
Zoosystematics and Evolution, 84 (2): 149–195.

Tekst omkring arten:

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.

Andinoacara:

Tekst:
Phylogenetic relationships among cichlasomatine cichlids were studied using an extensive taxon sampling and both morphological and molecular data sets. A new genus, Andinoacara n. gen. with six species (A. pulcher-rivulatus group of previous authors) from trans-andean South America and NW cis-andean South America, is described based on results of phylogenetic and diagnosability analyses and tests of alternative topologies Our results demonstrate that cichlasomatine cichlid diversity is divided into five principal lineages composed of eleven genera and three suprageneric clades: the [(Bujurquina, Tahuantinsuyoa), (Andinoacara) (BAT) clade; the (Cleithracara, (Nannacara, Ivanacara)] clade (NIC) plus Laetacara and 'Aequidens' hoehnei; and the (Aequidens, Cichlasoma) clade, where Aequidens is paraphyletic to Cichlasoma. Two former Aequidens species are additionally transferred into Krobia (K. potaroensis, K. paloemeuensis). 'Aequidens' hoehnei probably represents a unique evolutionary lineage and would thus qualify for a separate generic status. Molecular data are yet not available for this species and its generic status requires further study. Relationships between the three suprageneric clades and between Acaronia and Krobia could not be convincingly resolved with our data set of two mitochondrial (16S and cyt b) and two nuclear (S7 and RAG1) molecular markers and 96 morphological characters.

Super, så blev der lidt mere orden på "Aequidens".

Andinoacara pulcher (Gill, 1858)
Andinoacara rivulatus (Günther, 1860)
Andinoacara sapayensis (Regan, 1903)
Andinoacara spec. "Guldsøm"
Andinoacara spec. "Sølvsøm"

Hej Esben.
Ja det var også på tide vi lidt orden på mange af de de ubeskrevne arter som vi har kendt i mange år som for eks. Laetacara puckelkorpf
Som som nu endelig har fået navnet Laetacara araguaiae .Jeg glæder mig også til de nye navne på Aequidens slægten som bliver endelig offentlig gjort sidst på sommeren, hvor der kommer artsnavn på den vi har på den vi har kendt som Aequidens spec guldsøm og den vi har kaldt sølvsøm for der har været meget forviring om dem vi har kaldt Aequidens rivulatus.Så det er godt at du følger med på dette området og gør opmærksom på dette.
Venlig hilsen
