Short description
Khóa để định loại | Hình thái học | Sinh trắc học
This species can be distinguished from L. caucanus, L. saetiger, and L. tentaculatus by having abdominal plates (vs. absent), from L. schomburgkii
and L. saetiger by having dark spots in the dorsal and caudal fins (vs. white spots or all dark); and from L. guacharote by not having the abdominal plates restricted to a region near the insertion of the pectoral-fin spine (Ref. 56920).
Facultative air-breathing in the genus (Ref. 126274)
