Aenigmaticum californicum
minute hooded beetle
Aenigmaticum californicum is a species of minute hooded beetle in the family Corylophidae, first described by Thomas Casey in 1889. It is found in North America. The species belongs to a genus of very small beetles commonly known as minute hooded beetles or minute fungus beetles.
Arthrolips fasciata
Arthrolips fasciata is a minute beetle species in the family Corylophidae, originally described by Erichson in 1842. Records indicate presence in Belgium with some uncertainty, and the species has been observed 18 times on iNaturalist. Like other members of this family, it is among the smallest beetles, typically associated with decaying organic matter and fungal habitats. The genus Arthrolips is part of the diverse microbeetle fauna that remains understudied due to its diminutive size.
Clypastraea biguttata
Clypastraea biguttata
Clypastraea biguttata is a minute hooded beetle in the family Corylophidae, first described by LeConte in 1879. It belongs to a family commonly known as minute hooded beetles or minute fungus beetles, characterized by extremely small body size and a pronotum that conceals the head. The species is documented from North America, with specific records from Alberta and British Columbia in Canada. Like other members of its genus, it is likely associated with fungal substrates in decaying wood and bark.
Clypastraea fasciata
minute hooded beetle
Clypastraea fasciata is a species of minute hooded beetle in the family Corylophidae. Adults measure approximately 2 mm in length. The species occurs in North America, with records from Canada (Manitoba, New Brunswick, Ontario) and the United States. Like other members of its genus, it is associated with fungi and mold in rotting wood and under bark on dead trees.
Clypastraea lepida
minute hooded beetle
Clypastraea lepida is a species of minute hooded beetle in the family Corylophidae, first described by LeConte in 1852. It is among the smallest beetles in North America, measuring approximately 2 millimeters in length. The species belongs to a family commonly known as "minute hooded beetles" or "minute fungus beetles," characterized by a distinctive morphological adaptation where the head is concealed beneath a shelf-like projection of the pronotum. Members of the genus Clypastraea are typically associated with fungi and mold in rotting wood and under bark on dead trees.
Clypastraea obesa
A minute beetle in the family Corylophidae (minute fungus beetles), Clypastraea obesa was described by Casey in 1900. The species is documented from North America with records from British Columbia, Canada and Alaska, United States. Corylophidae are among the smallest beetles, typically associated with fungal substrates.
Clypastraea sp-one
minute hooded beetle, minute fungus beetle
Clypastraea sp-one is a minute beetle in the family Corylophidae, measuring approximately 2 millimeters in length. It belongs to a genus typically associated with fungi and mold in rotting wood and under bark on dead trees. The beetle was discovered in a residential Colorado Springs neighborhood, crawling on the base of a utility box beneath a cottonwood tree. This record represents a notable discovery of a poorly known group of beetles in an urban setting.
Gloeosoma hesperum
Gloeosoma hesperum is a minute beetle species in the family Corylophidae, a group commonly known as minute fungus beetles. First described by Casey in 1900, this species belongs to a genus characterized by extremely small body size and association with fungal substrates. The family Corylophidae is among the smallest beetles in North America, with most species measuring less than 2 mm in length. Records indicate presence in Nova Scotia, Canada, though detailed biological information remains sparse due to the cryptic habits and diminutive size of these insects.
Gloeosoma sticticus
Gloeosoma sticticus is a minute beetle in the family Corylophidae, commonly known as minute fungus beetles. The species was described by Casey in 1900 and is known from North America. Members of this genus and family are generally associated with fungal habitats.
Gloeosoma truncatus
Gloeosoma truncatus is a minute beetle in the family Corylophidae, commonly known as minute fungus beetles. The species was described by LeConte in 1852. Members of this family are typically associated with fungal growth and decaying organic matter. The genus Gloeosoma is characterized by its small size and distinctive body form among Corylophidae.
Holopsis convexa
Holopsis convexa is a minute beetle species in the family Corylophidae, a group commonly known as minute fungus beetles. The species was described by Casey in 1900 and is known to occur in North America. Members of this family are typically associated with fungal growth and decaying organic matter. Like other corylophids, H. convexa is likely extremely small in size, with adults often measuring less than 2 millimeters in length.
Holopsis marginicollis
minute hooded beetle
Holopsis marginicollis is a minute hooded beetle in the family Corylophidae, first described by LeConte in 1852. It occurs in eastern North America, with records extending into Canada. The species inhabits leaf litter and vegetation, typical of the microhabitat preferences of minute fungus beetles. As a member of Corylophidae, it belongs to a family of very small beetles often associated with fungal substrates and decaying organic matter.
Orthoperus
minute hooded beetles
Orthoperus is a genus of minute hooded beetles in the family Corylophidae, established by Stephens in 1829. The genus contains more than 20 described species, with at least 28 species currently recognized. Members are characterized by their extremely small body size and the distinctive hood-like pronotal structure that partially covers the head. These beetles belong to the tribe Orthoperini within the subfamily Corylophinae. They have been recorded from Europe and North America.
Orthoperus scutellaris
minute hooded beetle
Orthoperus scutellaris is a species of minute hooded beetle in the family Corylophidae, first described by LeConte in 1878. It is one of the smallest beetles in North America, measuring less than 1 mm in length. The species belongs to a family of beetles commonly known as minute hooded beetles or minute fungus beetles, though specific ecological details for this species remain poorly documented.
Parmulini
minute hooded beetles
Parmulini is a tribe of minute hooded beetles in the family Corylophidae, established by Poey in 1854. The tribe contains at least two genera—Arthrolips and Clypastraea—and more than 40 described species. These beetles are characterized by their small size and hooded body form. Members of this tribe are part of the superfamily Coccinelloidea within the suborder Polyphaga.
Rypobiini
Rypobiini is a tribe of minute hooded beetles within the family Corylophidae. The tribe contains at least 2 genera and approximately 14 described species. Members of this tribe are characterized by their small body size and the distinctive hood-like pronotal structure that partially covers the head. The tribe was established by Paulian in 1950.
Sericoderus lateralis
minute hooded beetle
Sericoderus lateralis is a species of minute hooded beetle in the family Corylophidae, first described by Gyllenhal in 1827. It is one of the smallest beetles, with adults typically measuring under 2 mm in length. The species has a remarkably broad geographic distribution spanning multiple continents including Africa, Australia, Europe, Northern Asia (excluding China), North America, and Southern Asia. Its wide range suggests either exceptional dispersal capabilities or cryptic species diversity requiring further investigation.
