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. Species formerly included here have been moved to Hyaloglanis and Salpynx.
There are currently two recognized species in this genus:
A. diaphanus originates from a stream tributary to the Javaés River of the Araguaia River basin in Tocantins, Brazil. 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.
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.
