Spatuloricaria Schultz, 1944


Spatuloricaria Schultz, 1944  ZBK  .

Type species: Spatuloricaria phelpsi Schultz, 1944  ZBK  .

Holotype: USNM 121121, Venezuela, Rio Socuy . 

Gender: feminine.

This genus is distributed in the northwestern part of the subcontinent, in drainages of the Pacific and Atlantic Slopes of the Andes. Several species occur also in the upper Amazon River basin, upper Paraguay, and São Francisco River basins. Ecological data are unavailable and reproductive biology is unknown. Sexual dimorphism includes hypertrophied development of claw-like odontodes along the sides of the head and on the pectoral spines in mature males. Spatuloricaria  ZBK  is in need of revision, as species boundaries and distributions are poorly known. The phylogenetic position of Spatuloricaria  ZBK  remains uncertain. Rapp Py-Daniel (1997) placed Spatuloricaria  ZBK  at the base of a clade including representatives of the Loricaria  ZBK  and Pseudohemiodon  ZBK  groups. Its dentition, with few teeth on the premaxillae, and its abdominal cover consisting of minute disjointed platelets resembles that of some representatives of the Loricaria  ZBK  group. Conversely, the papillose surface of the lips and sexually dimorphic features are more characteristic of the Rineloricaria  ZBK  group. Eleven valid species are currently recognized (Ferraris 2003).
