Miracetyma etimaruyagen. et sp. n. is proposed from the gills filaments of Curimata cyprinoides(Linnaeus, 1758), Potamorhina latior(Spix, 1829) and Psectrogaster essequibensis(Gunther, 1864).

| description | Miracetyma etimaruyagen. et sp. n. is proposed from the gills filaments of Curimata cyprinoides(Linnaeus, 1758), Potamorhina latior(Spix, 1829) and Psectrogaster essequibensis(Gunther, 1864). The species of the new genus is characterized by having a more complex latching antenna. The claw is greatly reduced and has a groove; the third segment has one or two grooves; the first, second and third segments have one or two cuticular extensions. The legs have pectinate setae and the first endopod is greatly modified, very long, and without setae. The first segment of the first endopod is large, strong and elongate and the second segment is subcylindrical, slender and elongate. These modifications imply in a loss of swimming capacity which is linked to secure fixation on the gill filament. As a result, the leg morphology has evolved other functions. |
