Habitat:
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. Description:
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.
