Astatotilapia

Astatotilapia burtoni

Astatotilapia is a genus of the family of cichlids ( Cichlidae ), the ( Astatotilapia desfontainesi ) were prepared from oases of North Africa for a type. Their validity and to be included species are controversial in the literature.

Validity

Pellegrin had overlooked when setting up the genus that some years earlier Hilgendorf had created a taxonomic unit for fish (namely Haplochromis ), which also corresponded Astatotilapia. Reganzog then a Astatotilapia. Greenwood revalidated the genus, they redefined and stretched them in many other ways, though he had to admit already here, that does not form a monophyletic unit Astatotilapia. Van Oijen summarized the criticism of this and other prepared by Greenwood genres that mainly overlaps with newly found species and the impossibility of already -existing types in the class ID one way or another Greenwood'sche genus, there is. Since Astatotilapia has since not redefined, the Council, for the time being not to use the name applies.

Features

Accordance with the established notion " Astatotilapia " species are 9-15 cm long, females stay smaller. In addition, they are usually colored plain, while the males are strikingly colored. The body is flattened laterally from typical cichlid shape and something. The head is large and beefy. From the closely related genus Haplochromis Astatotilapia be distinguished by the teeth in the outer rows of teeth are unicuspid or bicuspid in Astatotilapia and not laterally compressed or truncated obliquely. The teeth of inner rows of teeth are small and tricuspid. On the Pharyngealia the middle rows of teeth with enlarged, sometimes mahlzahnartigen teeth are occupied. The caudal fin is rounded. All Astatotilapia species are omnivorous and mouth brooders. On the anal fin wear them 3-9 eggspots.

Etymology

Pellegrin, who defined the genre, is the name from the words Gr. " Astatos " = unstable Tilapia (African cichlid genus ). The first part of the name refers to the teeth of the males in the outer jaw teeth, which are like the females first bicuspid, but are replaced by single pointed over the Aduleszens.
