Size 130mm or 5.1" SL. Find near, nearer or same sized spp.
IdentificationThe 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.

This species, from the Rio Zuata in Venezuela, is different from C. milesi in several respects, the most obvious being an almost double size vs. C. milesi. It has likely never been exported for the trade.
If you think you have this species, it is likely that you've got Chaetostoma sp. L445.
SexingThe 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.
General RemarksThis species is from an area in Venezuela that makes it very unlikely to appear in the trade - and it most certainly has never been exported for the trade.
