Ammoglanis is a genus of pencil catfishes native to South America.

Taxonomy

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.

Species

There are currently two recognized species in this genus:[2]

Distribution

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).

Description

Ammoglanis species grow to about 1.5–1.9 centimetres (0.59–0.75 in) SL.[3]

Ecology

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]
