Abstract: A taxonomic review of Spectracanthicus Nijssen & Isbrücker, including Oligancistrus Rapp Py-Daniel, following a phylogenetic study, is presented. Additionally to S. punctatissimus (Steindachner) and S. murinus Nijssen & Isbrücker, three new species are recognized based on the examination of 159 specimens: S. immaculatus n. sp. from rio Tapajós basin, differs from its congeners by its color pattern consisting of a dark gray body, with no dots or spots, and by having very slender teeth; Spectracanthicus tocantin… Show more

“…The new species has all these characters, however the anterior process of the metapterygoid is elongate and pointed (not spoon shaped), which also occurs in S. murinus and S. punctatissimus . Others features proposed for the genus by Chamon & Rapp Py‐Daniel () and that also occur in S. javae are: contact between sphenotic and IO6; the elongate anterior metapterygoid process; and the elongate lateropterygium, surpassing the vertical through the anterolateral process of the basipterygium.…”

“…Point-to-point measurements were made to the nearest 0·1 mm with digital callipers on the left side of the specimens, following Chamon & Rapp Py-Daniel (2014). Osteological nomenclature and vertebral counts follow Schaefer (1987), Armbruster (2004) and Geerinckx & Adriaens (2006) for compound pterotic and parieto-supraocciptal bones.…”

“…Pseudacanthicus pirarara is an important ornamental fish and commercial exploitation has been common practice in the middle to lower Rio Xingu since the 1980s. Such activities are economically profitable in some local communities and in many cases, constitute the entire source of income for multiple families (Camargo et al , ; Chamon & Rapp Py‐Daniel, ). Contrary to the understanding of most people, ornamental fishing activities do not exert a direct effect on the health of such fish communities (Andrews, ; pers.…”

“…Dam construction is a danger to the majority of the ornamental loricariids in the Amazon Basin. The Rio Xingu, like other Amazon tributaries, is suffering from an accelerated rate of dam construction and species that are naturally rare or endemic to specific habitats may suffer drastic population declines and even become extinct in nature (Rapp Py‐Daniel et al , ; Chamon & Rapp Py‐Daniel, ). Scientific understanding of different aspects of the fish fauna of Amazon drainages, including their taxonomy and biology, has not kept pace.…”
