Etymology

The specific name poikilos is derived from the Greek adjective ποικίλος, meaning variegated, varicolored, and refers to the intraspecific color pattern variation of the species.[1]

Habitat and ecology

The species' type locality (municipality of Júlio de Castilhos, arroio Passo dos Buracos, upper Jacuí river basin) is a rapid flow river with clear water, a rocky bottom and submerged vegetation, located at approximately 405 m a.s.l.; at this site, T. poikilos is associated with the submerged vegetation.[1]

T. poikilos feeds on aquatic larvae of Diptera (Simuliidae) and Lepidoptera and nymphs of the Ephemeroptera and Plecoptera.[1]
