| Summary of Megalechis|
||MEG ah LEK iss
||Megalechis: From the Greek megas, meaning large and lekis, meaning plate; in allusion to the extreme development of the coracoid bones on the breast of fully developed males.
||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 (vs. not fully covering the abdominal skin and not overlapping in females). Also, mature males of Callichthys, Dianema, Hoplosternum, Lepthoplosternum, and Megalechis have a thick adipose body on the ventral surface of the pectoral fin. Mature females of Dianema, Hoplosternum and Megalechis have a small fold of skin on the external face of the leading pelvic-fin ray.
