This monotypic genus is
known only from the upper Amazon River basin. Pterosturisoma
is a rheophilic species. Evers & Seidel (2005) described this
species as an open brooder. Males do not possess hypertrophied odontodes
neither on the sides of head, nor on pectoralfin spines. Nevertheless,
Evers & Seidel (2005) distinguished both sexes by the width
of a naked trapezoidal area framed by four bony plates in the genital
region. This area appeared broader in females, and longer and narrower
in males. Pterosturisoma appears morphologically very similar
to Lamontichthys from which it differs primarily in the
number of pectoral fin rays (i–6 in the former versus i–7
in the latter). These two genera share features with Sturisoma
such as similar body depth at dorsal-fin origin, presence of
filamentous extensions on caudal-fin spines, and complete abdominal
plate cover extending to the lower lip margin. These features are
never observed in Harttia, suggesting these two genera
share a closer relationship with Sturisoma than with Harttia
as hypothesized by Rapp Py-Daniel (1997). Aquarium care:
Very sensitive to low oxygen contents and poor water conditions.
Can be hard to get newly imported specimens to feed. Tank size should
be at least 4ft in length. A species that can only be kept by experienced
aquarists who are used to keeping members of this family. Diet:
Vegetable foods which can include peas. Other foods can also be
given. |
