Worthington, 1933, but has been treated as a valid species of Clariallabes by Teugels. Acrochordonichthys melanogaster Bleeker, 1854, is designated as type species of Acrochordonichthys Bleeker, 1857, inasmuch as no earlier valid designation has been found. A new genus Pseudobagarius, is proposed for the "pseudobagarius group" of species formerly placed in Akysis. The status of 228 species group names remains unresolved and 31 names based on otoliths ascribed to catfishes are listed but not placed into the checklist. The current emphasis given to catfish taxonomy at present is likely to result in a dramatic increase in the total number of valid taxa as well as major changes in the membership of some of the higher level taxa recognized here.

“…This large diversity has resulted in problems of species identification and many new species have been continuously described (Pereira and Oyakawa, 2003;Cardoso and Silva, 2004). Traditionally, Loricariidae has been divided in six subfamilies: Hypostominae, Ancistrinae, Loricariinae, Hypoptopomatinae, Neoplecostominae and Lithogeninae (Reis, Kullander and Ferraris Jr, 2003).…”

Karyotypic relationships among the tribes of Hypostominae (Siluriformes: Loricariidae) with description of XO sex chromosome system in a Neotropical fish species

et al. 2006

The family Loricariidae, with about 683 species, is one the largest fish families in the world. The subfamily Hypostominae was recently reviewed and is now divided in five tribes. With the main objective of contributing to a better understanding of the relationships of the members of the subfamily Hypostominae, cytogenetic analyses were conducted in seven species (three Hypostomini, three Pterygoplichthini and two Ancistrini) from Brazil and Venezuela. In Pterygoplichthini, all species show 2n = 52 chromosomes. In Hypostomini Hypostomus ancistroides has 2n = 68, H. regani 2n = 72 and Hypostomus goyazensis 2n = 72 chromosomes. In Ancistrini Ancistrus n. sp. 1 has 2n = 39/40 with a sex chromosome system of the type XX/X0, which is a novelty for neotropical fishes, and Ancistrus n. sp. 2 has 2n = 52 chromosomes. Six species have single Ag-NORs and two multiple Ag-NORs. The possible cytogenetic relationships among the species of Hypostominae are discussed.

“…Although some authors reported the presence of Bryconops species in the rio Tocantins (e.g., Lucinda et al, 2007;Lima & Caires 2011), Bryconops tocantinensis is the first species of Bryconops described from the rio Tocantins drainage and may be an additional example of exclusive fish species from its upper and middle portion, which is recognized by several authors as an area of endemism for several Neotropical freshwater fish groups (e.g., Cardoso & Lucinda, 2003;Bertaco & Carvalho, 2010;Bertaco et al, 2011aBertaco et al, , 2011b …”

A new species of Bryconops (Ostariophysi: Characiformes: Characidae) from the upper rio Tocantins drainage, Brazil

A new species of the genus Bryconops, subgenus Bryconops, is described from the rio Conceição, a tributary to the rio Palma, upper rio Tocantins drainage, Tocantins State, Brazil. The new species is distinguished from all its congeners, except B. humeralis and B. vibex by the color pattern in vivo (dorsal, adipose, and caudal fins entirely orange). The new species is easily distinguished from B. humeralis and B. vibex by the absence of a humeral spot and by the lack of maxillary teeth (vs. presence of a single humeral spot and presence of 1-3 maxillary teeth on both sides). Furthermore, the new species is distinguished from B. vibex by the number of perforated lateral line scales (38-41 vs. 44-46).Uma nova espécie do gênero Bryconops, subgênero Bryconops, é descrita do rio Conceição, um afluente do rio Palma, bacia do rio Tocantins, Estado do Tocantins, Brasil. A nova espécie distingue-se de suas congêneres, exceto B. humeralis e B. vibex pelo padrão de coloração in vivo (nadadeiras dorsal, adiposa e caudal inteiramente laranjas). A nova espécie distinguese de B. humeralis e B. vibex pela ausência de mancha umeral e pela ausência de dentes maxilares (vs. presença de uma mancha umeral e presença de 1 a 3 dentes maxilares em ambos os lados). Além disso, a nova espécie distingue-se de B. vibex pelo número de escamas com poros na linha lateral (38-41 vs. 44-46).
