[2] The entire classification history of the Acidocerinae was revised by Girón and Short in 2021,[1] based on the results of a phylogenetic analysis.
[1][3] According to Girón and Short:[1] Acidocerinae is a heterogeneous assemblage of beetles, as a variety of sizes, colorations and body shapes can be found in the group.
[...] Acidocerine species can be found across a wide variety of environments, spanning almost the full range of habitats that occur in the Hydrophilidae as a whole, including fully aquatic settings like ponds, streams, and river margins, hygropetric habitats like rock seepages, and terrestrial niches such as rotting fruits.
[...] Acidocerines, as a whole, occupy one of the widest habitat breadths of any aquatic beetle group, although most individual species are fairly narrow and predictable in their ecological preferences.
Consequently, collecting in a variety of habitats using multiple methods is often required to adequately survey a locality.– This Hydrophilidae-related article is a stub.
