Down Species Information
Size 60mm or 2.4" SL. Find near, nearer or same sized spp.
Identification Lepthoplosternum species are the smallest of the Callichthyinae (maximum SL = 60.3 mm). They are distinguished by two unique traits: (1) a lower lip with a deep medial notch and a smaller lateral notch, forming two fleshy semi-triangular projections on each side of the midline, and a single unbranched ray preceding the branched rays on the anal fin.

This species is sometimes confused with Callichthys callichthys. The visible coracoit bones by the pectoral fins is an indication that it is some form of Hoplosternum or Lepthoplosternum species. In Callichthys, this area is covered by skin and not visible (although the same bone is there in the fish. Callichthys also has a flatter overall body.
Sexing Mature males of Callichthys, Dianema, Hoplosternum, Lepthoplosternum, and Megalechis have a thick adipose body on the ventral surface of the pectoral fin. In Dianema, Hoplosternum, Lepthoplosternum and Megalechis (but not in Callichthys), the coracoid bones are at least partially exposed and expanded medially. In Dianema, Hoplosternum and Megalechis, these medial expansions of the coracoids are especially developed, covering most of the skin between the pectoral fins and sometimes overlapping at the midline in fully developed mature males, however there does not appear to be a similar sexually dimorphic expansion of the coracoids in Lepthoplosternum.
