Listed in GBIF
Description
This dataset contains the digitized treatments in Plazi based on the original journal article Peixoto, Luiz Antônio Wanderley, Wosiacki, Wolmar Benjamin (2010): Description of a new species of Tetranematichthys (Siluriformes: Auchenipteridae) from the lower Amazon basin, Brazil. Neotropical Ichthyology 8 (1): 69-75, DOI: 10.1590/S1679-62252010000100009, URL: scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252010000100009&lng=en&tlng=en Tetranematichthys barthemi is described from the mouth of the rio Trombetas and related tributaries (rios Saracá and Araticum) and rio Urubu, tributary of the rio Amazon.
Tetranematichthys barthemi shares with its congeners the anterior alignment of the mandibular barbels and well-developed portion of the protractor hyoid muscle connected to the mandibular barbel. It is distinguished from these species by a serrated anterior margin on the distal portion of the mandibular barbel, different from the more derived state which is composed of conspicuous digitiform elaboration in the distal portion of the barbel.

Tetranematichthys barthemi can also be distinguished from its congeners by combination of characters related to morphometry and coloration pattern. Comments on sexual dimorphism, changes to the extremities of the mandibular barbels and possible interspecific relationships are presented herein. Tetranematichthys barthemi é descrita para a foz do rio Trombetas e tributários correspondentes (rios Saracá e Araticum), e rio Urubu, tributário do rio Amazonas.
Tetranematichthys barthemi compartilha com seus congêneres (T. wallacei e T. quadrifilis) o alinhamento anterior dos barbilhões mandibulares e a porção do músculo protrator hióide ligado ao mesmo barbilhão bem desenvolvida. Distingue-se destas espécies por apresentar a porção distal do barbilhão mandibular serreada na margem anterior, diferente do estado, mais derivado, observado em seus congêneres, com conspícuas digitalizações na porção distal.
Distingue-se, também, de cada uma das espécies por conjuntos de caracteres combinados relacionados à morfometria e padrão de coloração. Comentários sobre dimorfismo sexual, modificações das extremidades do barbilhão mandibular e de relacionamento interespecíficos são apresentados.
