ormerly known by its common name of Spinipterus
sp. "Otorongo" as coming from the Río
Otorongo in Peru, this species finely got described
to go alongside Spinipterus
& Ferraris, 2011 from
theupper Amazon River basin in Peru and
Brazil in 2019 by Rocha et al. There are only these
two described species in the genera with possibly
another undescribed species from Guyana.

name of Spinipterus
was derived from Latin 'spina' for spine and Greek
'pterus' meaning wing, referring to the serrated nature
of the fin spines. The specific epithet moijiri
comes from Moijiri; this species is known among the
Paumari Indians that inhabit the Río Tapauá,
Purus basin. The meaning of the word Moijiri is unknown
so far. The Paumari language belongs to the Arawa

expedition to the middle Río Purus basin uncovered
a remarkable new species of the genus Spinipterus.
The new species has a very distinct and conspicuous
colour pattern resembling a jaguar and it is almost
four times larger than Spinipterus acsi,
a small specimen (32mm LS) from Caño Santa
Rita, a right bank tributary of Río Nanay in
Peru and a second specimen was reported from Río
Juruá, Amazonas State, Brazil. Although the
new species is more similar in size and colour pattern
to Liosomadoras, it shares the synapomorphies
for Spinipterus (Rocha et al. 2019).
Peru, Río Otorongo.
The Río Otorongo
in Peru is located in the Junín region,
in the central part of the country, 260 km
east of Lima, the capital of the country.
The Río Otorongo is part of the watershed
of the Amazon River.

Care & Compatibility
Keep in groups. Very nocturnal so provide caves and
structures for hiding during the day. Will be okay
with most other fish in the aquarium as long as they
are not too small.
This family practice
internal fertilisation with the female scattering
the eggs in the aquarium with no parental care. It
has been noted (Grant, S.) that S. acsi normally
lays its eggs in caves or pipes and guards them. Not
the easiest from this family to spawn and raise fry.
As in most Auchenipterids
the males have a modified anal fin and a dorsal fin
with larger anterior serrations. The females are deeper
