Coccinelloidea
Guides
Akalyptoischion
Akalyptoischion is a genus of coccinelloid beetles comprising at least 24 described species. It represents the sole genus of the family Akalyptoischiidae, having been reclassified from Latridiidae based on molecular phylogenetic evidence. The genus is restricted to western North America and exhibits specialized ecological associations with oak leaf litter and rodent nests.
Anamorphidae
Anamorphidae is a family of small fungus-feeding beetles in the superfamily Coccinelloidea, containing over 175 extant species across approximately 36 genera. The family was separated from Endomychidae by Robertson et al. (2015) based on morphological and molecular evidence. Members are obligate consumers of fungal spores in both adult and larval stages. A distinctive feature of the family is the presence of debris-cloaking behavior in larvae—a unique defensive strategy among Coccinelloidea that has evolved only once in this lineage.
Epipocus
handsome fungus beetles
Epipocus is a genus of handsome fungus beetles in the family Endomychidae. The genus was established by Chevrolat in 1836 and contains at least 20 described species. Members of this genus are classified within the subfamily Epipocinae, which is named after the genus itself. These beetles are part of the diverse Coccinelloidea superfamily, a group that includes many fungus-feeding beetles.
Euxestus
Euxestus is a genus of small beetles in the family Euxestidae, established by Wollaston in 1858. The genus comprises six described species distributed across tropical and subtropical regions. Members are characterized by their highly polished, smooth elytra. The genus is part of the superfamily Coccinelloidea within the diverse suborder Polyphaga.
Hypodacne
Hypodacne is a genus of beetles in the family Euxestidae, established by J.L. LeConte in 1876. The genus contains a single described species, H. punctata. These beetles are characterized by their well-polished, glossy appearance. The family Euxestidae was historically treated as part of Cerylonidae, and some sources still reflect this classification.
Micropsephodes
Micropsephodes is a small genus of beetles in the family Anamorphidae (formerly placed in Endomychidae), containing at least two described species. The genus was established by Champion in 1913. Species include Micropsephodes serraticornis (Champion, 1913) and Micropsephodes lundgreni Leschen & Carlton, 2000. Biological details remain poorly documented for most species.
Murmidiidae
Murmidiidae is a family of small beetles in the superfamily Coccinelloidea, containing approximately 34 described species across four genera. The family was historically classified within Cerylonidae but has been recognized as distinct based on morphological and phylogenetic evidence. Members are primarily associated with decaying wood habitats and are considered mycophagous. The cosmopolitan species Murmidius ovalis has been documented as a pest of stored food products.
Mycetaeidae
Mycetaeidae is a small family of beetles in the superfamily Coccinelloidea, established as distinct from Endomychidae based on morphological and molecular evidence. The family contains three genera: Agaricophilus (one species, Europe), Mycetaea (two species, North America, Europe, South Africa, and Canary Islands), and Afromycetaea (seven species, sub-Saharan Africa and Madagascar). The family is confirmed as monophyletic and sister to Cerasommatidiidae. Members of the genus Mycetaea are known to be mycophagous, feeding on molds.
Rhymbomicrus
Rhymbomicrus is a genus of small beetles in the family Anamorphidae, established by Casey in 1916. The genus contains four described species distributed in North America. Members of this genus are part of the diverse cucujiform beetle assemblage, though specific ecological details remain poorly documented.
Symbiotes
Symbiotes is a genus of beetles in the family Anamorphidae (order Coleoptera), established by L. Redtenbacher in 1847. The genus is accepted in the Catalogue of Life and classified within the superfamily Coccinelloidea. The name has been used in multiple unrelated contexts, including as a bacterial genus (Pseudomonadota, Rickettsiales) and as fictional extraterrestrial organisms in Marvel Comics. This record addresses the beetle genus.
Teredidae
Teredidae is a family of small beetles in the superfamily Coccinelloidea, containing approximately 160 species in 10 genera. The family has a cosmopolitan distribution excluding South America and Antarctica. Teredids are typically found in concealed microhabitats such as under bark, in leaf litter, and especially within the galleries of wood-boring beetles. The family was historically treated as a subfamily of Bothrideridae but is now recognized as distinct. Fossil records extend to the mid-Cretaceous with Delteredolaemus from Burmese amber.
