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.

The identifer LDA 41, like so many other L and LDA Numbers, was assigned to two species. It was originally assigned to a large plain brown colored sp from Mato Grosso, Brazil that reached 20 cm. It was later assigned to a Colombian sp that reaches 13 cm that is also plain brown, but has some lighter markings on the head and rostrum.
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.
