Ptilodactylidae
Guides
Anchycteis
Anchycteis is a genus of toe-winged beetles in the family Ptilodactylidae. The genus contains a single described species, A. velutina. Toe-winged beetles are characterized by their distinctive lobed tarsi. The family Ptilodactylidae is a small group of beetles with limited ecological documentation.
Anchycteis velutina
Anchycteis velutina is a species of toe-winged beetle in the family Ptilodactylidae, described by George Henry Horn in 1880. The genus Anchycteis is small and poorly documented, with limited ecological and biological information available. This species is known from North America, though specific details regarding its habitat preferences, behavior, and life history remain sparse in the scientific literature.
Anchytarsus bicolor
toed-winged beetle
Anchytarsus bicolor is a small toed-winged beetle in the family Ptilodactylidae, characterized by its distinctive bicolored pattern. It belongs to a family commonly known as toed-winged beetles or comb-clawed beetles, which are recognized by their modified tarsal claws. The species has been documented in eastern North America, with records from Canada and the United States.
Araeopidius
toe-winged beetles
Araeopidius is a monotypic genus of toe-winged beetles (family Ptilodactylidae) containing the single species A. monachus. Adults are uncommon and occur along the western coast of North America. The genus is notable for its three-year life cycle and unusual larval diet of woody material.
Araeopidius monachus
Araeopidius monachus is the sole species in the subfamily Araeopidiinae within the beetle family Ptilodactylidae. It is endemic to western North America, where adults are rarely encountered. The species exhibits an unusual three-year life cycle among beetles, with larvae feeding on woody material while adults appear to be non-feeding. Its biology remains poorly understood due to the scarcity of specimens and limited field observations.
Lachnodactyla
Lachnodactyla is a genus of toe-winged beetles in the family Ptilodactylidae, established by Champion in 1897. The genus contains at least two described species: L. arizonica and L. texana, both described by Schaeffer in 1906. These species are known from the southwestern United States. The family Ptilodactylidae is characterized by expanded tarsal segments that give the common name 'toe-winged beetles'.
Lachnodactyla arizonica
toe-winged beetle
Lachnodactyla arizonica is a species of toe-winged beetle in the family Ptilodactylidae. It was described by Schaeffer in 1906. The species is known from North America, with the specific epithet suggesting a primary association with Arizona. Like other members of Ptilodactylidae, it possesses the distinctive expanded hind tarsi that give the family its common name of toe-winged beetles.
Lachnodactyla texana
toe-winged beetle
Lachnodactyla texana is a species of toe-winged beetle in the family Ptilodactylidae, first described by Schaeffer in 1906. The species is distributed across Central America and North America. As a member of the Ptilodactylidae, it belongs to a family characterized by beetles with expanded tarsal segments that bear adhesive setae, commonly referred to as 'toe-winged' beetles. Very few specific biological details have been documented for this particular species.
Paralichus
toe-winged beetles
Paralichus is a genus of toe-winged beetles in the family Ptilodactylidae, established by White in 1859. The genus is monotypic, containing a single described species, P. trivittus. Toe-winged beetles are characterized by their distinctive expanded hind tarsi. Members of this family are generally associated with riparian or moist habitats.
Ptilodactyla
toe-winged beetles
Ptilodactyla is a large and cosmopolitan genus of toe-winged beetles comprising approximately 370–380 described species, representing roughly 70% of all species in the family Ptilodactylidae. The genus is characterized by distinctive morphological features including pectinate male antennae with articulated rami, incomplete lateral pronotal carinae anteriorly, concealed trochantins, and pseudotetramerous tarsi with reduced tarsomere IV and lobed tarsomere III. Fossil records extend to the Eocene, with specimens described from Baltic amber (Russia) and Rovno amber (Ukraine). Some species have been introduced outside their native ranges through human activity.
Ptilodactyla angustata
toe-winged beetle
Ptilodactyla angustata is a species of toe-winged beetle in the family Ptilodactylidae. It was described by Horn in 1880. The species is known from North America. Like other members of its family, it possesses distinctive modified hind tarsi that resemble small claws or 'toes', a characteristic feature of Ptilodactylidae.
Ptilodactyla carinata
toe-winged beetle
Ptilodactyla carinata is a species of toe-winged beetle in the family Ptilodactylidae, first described by Johnson and Freytag in 1978. The species occurs in North America, with records from Canada (Québec) and the United States. Like other members of its family, it possesses the characteristic expanded hind tarsi that give toe-winged beetles their common name. The family Ptilodactylidae is a small group of beetles whose biology remains poorly documented.
