Helochares is a genus of water scavenger beetles in the family Hydrophilidae, represented by 161 described species. It is distributed across the Afrotropical, Australasian, Indo-Malayan, Nearctic, and Palearctic realms. [1]

Taxonomy

Helochares is one of the largest and most taxonomically problematic genera within the Acidocerinae. It was originally described by Étienne Mulsant in 1844. [2]

For a long time Helochares contained five subgenera: Batochares (currently regognized as a separate genus [3]), Helochares, Helocharimorphus (now synonymized under Helochares [1]), Hydrobaticus (now synonymized under Helochares [1]), and Sindolus (currently regognized as a separate genus [3]).

Several taxa that used to be recognized as typical Helochares are now assigned to newly created genera (e.g., Colossochares, Novochares) or re-assigned to exinsting genera (i.e., Peltochares), based on a phylogenetic analysis based on molecular data. [3]
Description

As currently defined, Helochares contains small to medium-sized beetles (2–7 mm), which are yellowish to brown in coloration. There is a lot of variation in the impression of the elytral punctation, and the aedeagal forms are also highly variable (see Figure 37 in Girón and Short 2021).[1] A detailed diagnosis can be found in Girón and Short 2021.
