Liocanthydrus is a genus of beetles belonging to the family Noteridae, the burrowing water beetles.[1][2][3] The genus is Neotropical with records from Brazil, Venezuela, French Guiana, and Paraguay.[4][5] It was originally established as a subgenus of the otherwise Old World genus Canthydrus.[4]
Description
[edit]Liocanthydrus are medium-sized beetles measuring 2.7–3.4 mm (0.11–0.13 in) in total length. The body is elongate, oval, weakly to moderately convex, and posteriorly attenuate. The appearance is very shiny. The elytra are iridescent and brown to nearly black. The pronotum and head coloration range from yellow to darker reddish brown.[4]
Ecology
[edit]Liocanthydrus are aquatic beetles most commonly collected in lotic (flowing-water) habitats. Specimens have typically been found along the margins of such habitats or in debris such as logs, leaf packs, or root mats.[4][6] They are generally rare.[5]
