Hoplisoma evelynae, Evelyn's cory, is a species of freshwater ray-finned fish belonging to the subfamily Corydoradinae, the corys, of the family Callichthyidae, the armoured catfishes.[2] This catfish is found in Colombia, being known to occur in the upper Solimões River, and probably in eastern Brazil as well.[1]
Hoplisoma evelynae is oviparous. The female holds a batch of between 2 and 4 eggs between her pelvic fins, and the male takes around 30 seconds to fertilise each batch. The female then swims to a suitable spot, where she attaches the very sticky eggs. They repeat this process until around 100 eggs have been fertilised and stuck to a substrate.
This species has a maximum standard length of 4 cm (1.6 in).[3]
Hoplisoma evelynae is traded in the aquarium industry.[1]
Hoplisoma evelynae has a specific name which was not explained by the author, Fritz Rössel, but which almost certainly honours Evelyn Axelrod, the wife of Herbert R. Axelrod.[4]
