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 recognized as a separate genus [3] ), Helochares, Helocharimorphus (now synonymized under Helochares [1] ), Hydrobaticus (now synonymized under Helochares [1] ), and Sindolus (currently recognized 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. [1]
