Aphanotorulus is a genus of armored catfishes native to the Amazon, Orinoco, Essequibo and Jaguaribe basins in South America.[2][1] They typically occur on a sand or gravel bottom in slow to moderately flowing rivers and streams,[3] but some species occur in areas with fast current.[4] The largest species in the genus reaches up to 51 cm (20 in) in standard length.[3]
Taxonomy
[edit]The taxonomy of this genus has been a matter of dispute, all having been placed in Hypostomus in the past, and some occasionally placed in Squaliforma. Squaliforma is now regarded as a synonym of Aphanotorulus, but species west of the Andes have been moved to Isorineloricaria.[1]
There are currently 7 recognized species of Aphanotorulus:[1][4]
- Aphanotorulus ammophilus Armbruster & Page, 1996
- Aphanotorulus emarginatus (Valenciennes, 1840)
- Aphanotorulus gomesi (Fowler, 1941)
- Aphanotorulus horridus (Kner, 1854)
- Aphanotorulus phrixosoma (Fowler, 1940)
- Aphanotorulus rubrocauda Oliveira, Py-Daniel & Zawadzki, 2017
- Aphanotorulus unicolor (Steindachner, 1908)
Of these species, the validity of A. phrixosoma is questionable, as the only known specimen likely is a hybrid between A. horridus and A. unicolor.[1]
