Acidocerinae is a subfamily In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoologi ... in the family Hydrophilidae of aquatic beetles, and it contains over 500 species in 23 genera. Taxonomy Acidocerinae has been considered a subfamily since Short and Fikáček restructured the classification of the Hydrophilidae in 2013. The entire classification history of the Acidocerinae was revised by Girón and Short in 2021, based on the results of a phylogenetic analysis. The subfamily currently contains over 500 species in 24 genera, some of which were erected in 2021.

Hydrophilidae
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae (= Georyssinae), Helophoridae, Hydrochidae, and Spercheidae (= Sphaeridiinae). While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae. With rare exceptions, the larvae are predatory while the adults may be herbivores or predators in addition to scavenging. Many species are able to produce sounds. Species of '' Hydrophilus'' are reported as pests in fish hatcheries. Other species are voracious consumers of mosquito larvae, and have potential as biological control agents. This beetle family contains 2,835 species in 169 genera. Geography Hydrophilid beetles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfamily (biology)
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While olde ... Sources {{biology-stub ...

Tobochares
''Tobochares'' is a Neotropical genus of water scavenger beetles in the family Hydrophilidae represented by 24 described species known from the Guiana Shield Region. Taxonomy The genus ''Tobochares'' belongs in the subfamily Acidocerinae. It was first described by Short and García in 2007.

Sindolus
''Sindolus'' is a Neotropical genus of water scavenger beetles in the family Hydrophilidae represented by eight described species, ranging from Mexico to Argentina, and including one species recorded from Antigua in the Lesser Antilles. Taxonomy The genus ''Sindolus'' belongs in the subfamily Acidocerinae. It was first described by David Sharp in 1882 to accommodate two Central American species. Since 1919 ''Sindolus'' was considered a subgenus of the genus '' Helochares'' by d’Orchymont and stayed in that category until a molecular-based phylogenetic analysis supported its restitution at the category of genus. Description Small to sized beetles (2.5–5.0 mm), smooth and shiny dorsally, moderately to strongly convex in lateral view; yellowish, orange-brown, to brown in coloration, with long maxillary palps. The most distinctive characteristic of ''Sindolus'' is the presence of a sharp and strongly elevated (laminar) longitudinal carina on the mesoventrite. ...
