Neuhaus EB, Britto MR, Birindelli JLO, & Sousa LM. (2022). A new species of Ancistrus (Siluriformes: Loricariidae) from Tapajós and Xingu basins, Brazil. Neotrop Ichthyol, 20(1):e210129. https://doi.org/10.1590/1982-0224-2021-0129
A new Ancistrus species is described from Tapajós and Xingu river basins. It is distinguished from its congeners by the singular body color pattern, consisting of dark vermiculated stripes almost all over the body, and also by combination of features as a narrow head, large internostril distance, and absence of rows of enlarged odontodes on the lateral plates. In addition, the new species is distinguished from congeners that inhabit the rio Tapajós basin by the presence of a fully-developed adipose fin (vs. adipose fin absent in
and A. tombador, and vestigial adipose fin or absent in A. krenakarore). It differs from A. ranunculus, also from the rio Xingu, by the color pattern, smaller body size, smaller gill opening, and narrower cleithral width. The new taxon adds a new record to the list of species shared among the Xingu and Tapajós basins.

Hi Clay,
Hope you're well!
This species was first given an L number in the mid 1990s. It's not really common in the hobby, but I've seen it around a few times. I agree, it would be great to see more of these in the hobby.
