Hoplosternum is a genus from the family of callichthyidae (Callichthyidae).

features

The species of the genus Hoplosternum, which are widespread in South American waters, differ greatly in their external appearance from the usual image of the Corydoras armored catfish. They have an almost cylindrical body and a straight and only slightly incised caudal fin. The Hoplosterna species differ from the members of the closely related genus Callichthys in that the dorsal bone plates are firmly connected and the side plates are firmly connected between the dorsal fin and the adipose fin .

The members of the genus Hoplosternum , unlike most representatives of the armored and callous catfish , build foam nests in which the females lay the fertilized eggs.

Systematics

At least three species are known from the genus Hoplosternum :

• Genus Hoplosternum Gill , 1858
  • Hoplosternum littorale ( Hancock , 1828)
  • Hoplosternum magdalenae Eigenmann in Ellis, 1913
  • Hoplosternum punctatum Meek & Hildebrand , 1916

The Magdalene callus catfish (formerly Hoplosternum pectorale ( Boulenger , 1895)) is now classified as Lepthoplosternum pectorale of the genus Lepthoplosternum and Hoplosternum thoracatum ( Valenciennes in Cuvier and Valenciennes, 1840) was recognized as a synonym for Megalechis thoracata .
