Relevant Information:

Has a relatively wide, albeit scattered, distribution in the central and western portions of the Amazon basin and possibly the southwestern portions of the río Orinoco basin. The type series of Denticetopsis seducta that originated in the Río Ucayali basin and in the region of Iquitos in northeastern Peru, and the non-type population samples of the species from the Rio Aripuanã in the rio Madeira basin, Brazil agree in all examined features. A single specimen that originated in the upper Río Napo in eastern Ecuador (ANSP 139105) and which is tentatively identified as Denticetopsis seducta has slightly higher number of total vertebrae (43) than the 39 to 42 total vertebrae that occur in the other examined specimens assigned herein to that species. Additional population samples of Denticetopsis from the upper Río Napo basin are necessary to determine whether this specimen represents yet another undescribed species.
