Relevant Information:

Description: According to Bockmann and Miquelarena (2008), Rhamdella was proposed by Eigenmann and Eigenmann (1888) as a subgenus of Rhamdia Bleeker, 1858, from which it was distinguished by having a cranial fontanelle extending to the base of the supraoccipital, as opposed to not having this fontanel continue behind the eye (Eigenmann and Eigenmann 1888). Habitat: Rhamdella eriarcha is distributed in the Jacuí river basin, a tributary of the Patos lagoon system, Rio Grande do Sul, Brazil (Bockmann and Guazzelli 2003). Etymology: The genus name of Ramdella: –ella, a diminutive, proposed as a subgenus of Rhamdia. The specific name of longiuscula : diminutive of longior, longer, i.e., a little longer, referring to longer upper lobe of caudal fin compared to R. eriarcha.
