Ammoglanis is a genus of pencil catfishes native to South America.
The relationships of the genus Ammoglanis are unknown; it is thought that this genus along with undescribed forms are the sister group to a large intrafamilial clade composed of several genera and subfamilies. In the interim, this genus is included within Sarcoglanidinae. [1] Species formerly included here have been moved to Hyaloglanis and Salpynx .
There are currently two recognized species in this genus: [2]
A. diaphanus originates from a stream tributary to the Javaés River of the Araguaia River basin in Tocantins, Brazil. [3] A. multidentatus originates from the Rio São José drainage, upper Rio Paraguaçu basin, Bahia State (Brazil).
Ammoglanis species grow to about 1.5–1.9 centimetres (0.59–0.75 in) SL. [3]
A. diaphanus inhabits shallow, narrow, clear water, moderately swift-flowing stream and is found buried in the sand. It feeds on Diptera larvae and cladocerans. [3]
