型態特徵 | 形態測量圖
脊椎骨: 40. This species is distinguished and differs from its congeners by the following characters: gill rakers on the first branchial arch 26-30 (vs. 18-27); sides of trunk with 3-6 rows of dark spots which are regularly or irregularly scattered and several small dark spots irregularly scattered on the dorsal surface of head, supraoccipital process, and sometimes on the dorsal and caudal fins; striated lips; maxillary barbels reaching between posterior tip of the pelvic-fin rays and posterior tip of the middle caudal-fin rays (Ref. 86673).
This species is widepread throughout the rio Ribeira de Iguape drainage, ranging from the altitudes of 3 m above sea level at the rios Pariquera-Açu and Pariquera-Mirim in the lower stretch of the rio Ribeira de Iguape, to 250 m above sea level at the rio Catas Altas in the high stretch of the river basin. It was found mainly in the large rivers like Ribeira de Iguape, Catas Altas, Pariquera-Mirim and Turvo; rivers of the high stretch have clear water running over rocks and sand; rivers of the low stretch have a turbid water, and in some case, acid black water like the rio Momuna, at the sandbank forest near the mouth of the rio Ribeira de Iguape into the sea. At the type locality, this species occurs syntopically with the following species: Cyphocharax santacatarinae, Hoplias malabaricus, Oligosarcus hepsetus, Hoplosternum littorale and Crenicichla iguapina (Ref. 86673).
