Down arrow Species Information
Size 46mm or 1.8" SL. Find near, nearer or same sized spp.
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.
