Relevant Information:

Otothyropsis marapoama, a new genus and species, is described based on specimens recently collected in a headwater stream of the middle stretch of the rio Tietê, a river from the upper rio Paraná basin in southeastern Brazil. The new taxon belongs to a clade also encompassing the genera Schizolecis, Otothyris and Pseudotothyris. Otothyropsis marapoama is hypothesized to be the sister-group of Pseudotothyris and Otothyris based mainly on the presence of several derived characters of the swimbladder capsule and associated bones. Several paedomorphic characters shared by Pseudotothyris and Otothyris and their significance for the phylogenetic position of the new genus are discussed (Ribeiro, A.C et al). Aquarium Care: Treat as with all members of the Hypoptopomatinae such as the Otocinclus/Parotocinclus genera with a planted aquarium and an overall cooler temperature. Diet: Omnivore: algae, tablet foods, flake and small frozen foods. Remarks: There are now 6 species in this relatevely new genera, Otothyropsis alicula, O. biamnicus, O. marapoama, O. piribebuy, O. polyodon and O. dialeukos.
