AbstractThree new species of saddled hypostomine loricariids are described. According to a recent phylogenetic analysis, these species are members of the genus Peckoltia. The species differ from all described Peckoltia except P. furcata and P. sabaji by having the dentaries meet at an angle greater than 90°. The species also have similarities to Hemiancistrus, and can be separated from all described species by having dorsal saddles. We discuss the taxonomy of Peckoltia, Hemiancistrus, and allied genera and recognize Ancistomus as valid for P. feldbergae, H. micrommatos, Ancistrus snethlageae, H. spilomma, and H. spinosissimus. We recommend descriptions of genera for several clades of Hemiancistrus and restriction of Hemiancistrus to the type species of the genus, H. medians. Chaetostomus macrops is transferred to Pseudancistrus and recognized as a junior synonym of P. megacephalus. The Hemiancistrus annectens group of species (H. annectens, H. argus, H. aspidolepis, H. fugleri, H. holostictus, H. maracaiboensis, H. panamensis, H. wilsoni) are recognized in Hypostomus. Multivariate analysis reveals that the newly described species differ from one another in shape space, but overlap broadly with other Peckoltia (P. lujani), narrowly with other Peckoltia (P. greedoi), or broadly with Etsaputu (P. ephippiata).

- Peckoltia lujani - hier handelt es sich wohl um L127
Bereits in den ersten Zeilen fällt auf, dass in der Arbeit nun die Gattung Ancistomus anerkannt wird. Insbesondere folgende Arten wurden den Ancistomus zugeordnet:
- Ancistomus feldbergae (L12 / L13)
- Ancistomus micrommatos (2003 als Hemiancistrus micrommatos beschrieben)
- Ancistomus spilomma (L36)
- Ancistomus spinosissimus (2003 als Hemiancistrus spinossissimus beschieben)
- Ancistomus snethlageae (L141/L215)
Darüber hinaus wurde die Gattungszuordnung geändert bei:
- Hemiancistrus pankimpuju -> Peckoltia pankimpuju (L350)
