I konw this isn't a big deal...but taxonomy is something which has interested me so the question has been picking at my brain all morning. Is Haplochromis sp. 35 the new genus name or the old genus name of the Haplochromis sp. 35 "Tomato"? I ask this because I know they are also reffered to as Astatotilapia sp. "tomato".

Thanks,
Dave.

Haplochromis was and is a catch all genus for many cichlids. As taxonomists work with various fish, they have created a new genus for related fish. The new genus is Astatotilapia. Not all Haplochromis are Astatotilapia, only a few with close relationships.

In Europe, they prefer a numbering system when putative species are identified. L numbered plecos are one example. As cichlids were exported from Lake Victoria, someone assigned each putatively different species a number. However, in America we tend to like names. Therefore numbers become names for identical fish. Examples are Haplochromis sp. 44 called Haplocrhomis sp. "thickskins" and Haplochromis sp. 35 called Haplochromis sp. "tomatoe". Saying or writing Haplochromis sp. 35 "tomatoe" is a bit redundant but it also helps novice realize there are not two different fish but that 35 and tomatoe are same fish.

Haplochromis sp. 35 or tomato is not a variant, location morph, etc of Pundamilia nyererei
When a new fish is exported from Lake Victoria to Europe, a provisional number is given until ichthyologist describes fish. In USA that same fish is given a provisional name. Thus:
Haplochromis sp. 35 is the same fish as Haplochromis sp. "tomato"

Here is an image by loverland of Haplochromis sp. 35 or tomato
