Ancistrini sp L127
This L-number has been referred to as Peckoltia lujani since the work of Armbruster et al. (2015) [Armbruster JW, Werneke DC, Tan M (2015) Three new species of saddled loricariid catfishes, and a review of Hemiancistrus, Peckoltia, and allied genera (Siluriformes). ZooKeys 480: 97-123] as Peckoltia lujani. I do not agree with this assessment at all, this is never a catfish of the genus Peckoltia, unless one continues to treat this genus as a collective genus into which everything is grouped that one does not really know where to categorise.
I would follow the opinion of Seidel & Evers (2005) [I. Seidel / H.-G. Evers ‘Welsatlas 2’ Edition: 1 (2005) p.404] (undescribed genus) and, based on my own observations (morphology, reproduction, larval development, pattern changes during juvenile development), I would rather classify the species in the direction of the genus Ancistomus.
