Overview

Comprehensive Description

[[ Genus Acestridium ]]

The Neotropical catfish genus Acestridium (Siluriformes: Loricariidae) is currently represented by three species with general distributions in the middle and upper Orinoco, Casiquiare, and Rio Negro basins of Venezuela and Brazil (Retzer et al., 1999). Recently, a previously unknown collection of Acestridium was discovered at the Field Museum of Natural History, Chicago, Illinois, USA. Further examination of these specimens in a single lot revealed the specimens to represent an undescribed species and the first record of Acestridium in Colombia.

Acestridium

Acestridium is a genus of freshwater fish in the family Loricariidae of order Siluriformes. The type species is Acestridium discus. The genus name is derived from Latinised Greek 'agkistron' meaning hook.[1]

Acestridium species are native to small streams of the Amazon region of Brazil, Venezuela, and Colombia.[2] Species of this genus are found in litter banks.[3]

Members of this genus typically are long and thin, or 'twiglike' and superficially resemble the genus Farlowella of the same family. Adult length is 5–7 cm and each species shows adaptation for camouflage in the water margins - bright green leaf like in Acestridium dichromum[4] and varigated brown in other species.[5]

Species

There are currently seven recognized species in this genus:[1]
