Pareiorhina rudolphi explained

Pareiorhina rudolphi is a species of armored catfish endemic to Brazil where it occurs in the Paraíba do Sul River near Lorena, São Paulo State, Brazil.^[1] This species grows to a length of 4.5cm (01.8inches) TL.

Etymology

The fish is named in honor of Rodolpho von Ihering (1883-1939), a zoologist and fish culturist, who first described this catfish as Plecostomus (Rhinelepis) microps in 1907, but used a preoccupied name (Plecostomus microps Steindachner 1876) and so it was renamed.^[2]
