Aulonochares is a Neotropical genus of water scavenger beetle in the family Hydrophilidae represented by three described species known from the Guiana Shield Region.

[2] It belongs in the subfamily Acidocerinae and contains three described species from Brazil (Amazonas, Roraima), French Guiana, Guyana, Suriname, and Venezuela.

[1][2] Medium-sized beetles (5.8–7.5 mm), smooth and shiny dorsally, orange-brown in coloration, with long maxillary palps.

[1] According to Girón and Short:[1] Specimens of Aulonochares have been collected in densely forested sandy streams and detrital pools in forests along creeks.

They seem to prefer habitats with abundant detritus or decaying organic matter.
