|All Fishes Data Sheet|
|Scientific Name||Lepthoplosternum altamazonicum Reis, 1997|
|Type Locality||Río Ucayali, Pucallpa, Peru.|
|Pronunciation||lep THOP low STERN um|
|Etymology||Lepthoplosternum: From the Greek leptos, meaning small and hoplosternum; in reference to the small size. Hoplosternum: From the Greek hoplon, meaning shield and sternum, meaning breast; in reference to the prominent coracoid bones on the breast.|
|Size||50mm or 2" 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.|
|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.|
|Distribution||South America: Upper Amazon River drainage in Peru; range extended to the area of confluence of the Rio Solimões and Rio Japurá, Brazil.
