|Cat-eLog Data Sheet|
|Scientific Name||Chaetostoma branickii Steindachner, 1881|
|Type Locality||Cajamarca, Rio Chota [Chotano], Peru, elevation 1465-1585 meters.|
|Pronunciation||KATE oh STOW mah|
|Etymology||Greek, chaite = hair + Greek, stoma = mouth. This species is named formosae, an adjective in genitive case derived from the latin formosa. The name honours my sister, Laura María Ballen, in recognition of her unconditional love and support to me.|
|Size||135mm or 5.3" SL. Find near, nearer or same sized spp.|
|Identification||The genus Chaetostoma is not straightforward to identify, but as a general rule, the species has spines behind the gill-cover (interopercular odontodes), no plates on the abdomen, and aside from C. platyrhynchus also lack plates on the snout edge. Different from Ancistrus by not having fleshy tentacles on the snout.|
|Sexing||The males have however a larger and broader head, slimmer ventral sides and disproportionately large pelvic fins. Perhaps the over-sized pelvic fins play a large role in the fertilization of the eggs. By inverting these over the clutch of eggs, they prevent the sperm cells being carried away by fast water current.|
|Distribution||Upper Chamaya River basin in upper Marañon River drainage, Peru.
