Are Scattered Microsatellites Weak Chromosomal Markers? Guided Mapping Reveals New Insights Into Trachelyopterus (Siluriformes: Auchenipteridae) Diversity [PDF]

PLoS ONE, 2023
The scattered distribution pattern of microsatellites is a challenging problem in fish cytogenetics. This type of array hinders the identification of useful patterns and the comparison between species, often resulting in over-limited interpretations that

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae). [PDF]

J Fish Biol
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

Distribuição e abundância relativa de cumbaca Trachelyopterus striatulus Steindachner (Osteichthyes, Auchenipteridae) no reservatório de Lajes, Rio de Janeiro, Brasil [PDF]

Revista Brasileira De Zoologia, 2002
The catfish Trachelyopterus striatulus Steindachner, 1877 is a very abundant fish species in reservoirs in Southeast Brazil, and its relative abundance seems to be increasing in several lentic environments. Despite of being a very common species, few information is available on its distribution and other aspects of ecology.

Contributions to the taxonomy of Trachelyopterus (Siluriformes): comparative cytogenetic analysis in three species of Auchenipteridae [PDF]

Neotropical Ichthyology, 2021
Auchenipteridae is divided into subfamilies Centromochlinae and Auchenipterinae. Parauchenipterus is included in the latter and is subject of taxonomic discussions concerning its validation or synonymization with Trachelyopterus.

[The fish Trachelyopterus striatulus (Siluriforms: Auchenipteridae) used to sample insects in a tropical reservoir].

Revista de biologia tropical, 2010
The study of aquatic environments is sometimes difficult to do with normal sampling methods that use gears. Insectivorous fishes represent good users of these ecosystems and analyzing the aquatic organisms present in fish stomachs, is an alternative way to determine resource abundance and utilization.
