Quadriops is a Neotropical genus of water scavenger beetle in the family Hydrophilidae represented by six described species.

[1] The genus Quadriops was described for the first time by Michael Hansen in 1999.

After a revision of the genus, it now contains six described species from Brazil (Amazonas), Costa Rica, Ecuador, French Guiana, Guyana, Panama, Peru, Suriname, and Venezuela.

[1][3] Small to tiny beetles (1.6–2.6 mm), orange brown to dark brown in coloration, with eyes fully divided in dorsal and ventral faces; short maxillary palps.

[1] Quadriops is the only genus of Neotropical acidocerines known only from terrestrial habitats, including rotten fruits, sap flows on freshly cut trees, and in the refuse piles of leafcutter ants.
