abstract (from publication):
Rineloricaria misionera is a new species from the Paraná and Uruguay River basins, Misiones, Argentina. The new species is distinguished from all others in the genus by the following combination of characters: anterior abdomen covered by plates, except for the area corresponding to the pectoral girdle, which usually lacks plates, when present in this region, plates are relatively small and few; posterior abdomen with a well-developed preanal plate, bordered anteriorly by a series of 3–5 usually polygonal plates; premaxillary and dentary teeth with asymmetric cusps; uppermost caudal ray not prolonged in a filament; and snout tip with an oval naked area not reaching the last pore of the infraorbital sensory canal.
distribution & habitat (from publication):
Paraná and Uruguay River basins in Misiones Province, Argentina. Small streams having swift current over rocky and sandy bottoms. Individuals seek shelter between rocks, gravel, and crevices during the day, and are active mainly during the night.
remarks:
For the collection of the paratypes ILPLA 1546 and 1551 financial support was provided by the GfI (German Association for Ichthyology). A fact that the second author forgot to acknowledge. |
