Abstract:
Three 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).
