Harpalinae
Guides
Oodini
Oodini is a tribe of ground beetles (Carabidae: Harpalinae) containing over 400 species in 43 genera, with highest diversity in tropical Africa. Members are generally associated with standing water habitats. The tribe is distinguished by two diagnostic morphological characters: a laterally coadunate metepisternum and an elytral ridge formed by fusion of elytral intervals 7 and 8.
Oxycrepis intercepta
Oxycrepis intercepta is a species of ground beetle in the family Carabidae. It occurs in North America, with records from Mexico and the United States. As a member of the tribe Harpalini, it belongs to a diverse group of predominantly ground-dwelling beetles. Published information on its biology and ecology remains limited.
Pelmatellus
Pelmatellus is a genus of ground beetles in the family Carabidae, established by Henry Walter Bates in 1882. The genus contains at least 20 described species and is the type genus of the tribe Pelmatellini within the subfamily Harpalinae. As with other ground beetles, species in this genus are likely predatory, though specific ecological details remain poorly documented.
Philodes rectangulus
Rectangular Harp Ground Beetle
Philodes rectangulus is a species of ground beetle in the family Carabidae, commonly known as the Rectangular Harp Ground Beetle. It is native to North America, with records from both Canada and the United States. The species was originally described as Acupalpus rectangulus by Chaudoir in 1868 and later transferred to the genus Philodes. It belongs to the subfamily Harpalinae, a diverse group of ground beetles often associated with open habitats.
Piosoma setosum
Piosoma setosum is a species of ground beetle in the family Carabidae, notable as the sole member of its monotypic genus. First described by LeConte in 1847, this beetle occurs in North America. The genus name derives from Greek, reflecting its distinctive setose (bristly) characteristics. Despite its taxonomic uniqueness, detailed biological information remains limited.
Pterostichini
Woodland Ground Beetles
Pterostichini is a tribe of ground beetles in the subfamily Harpalinae, commonly known as woodland ground beetles. The tribe contains approximately 180 genera and over 3,800 described species, though estimates vary. Members are primarily ground-dwelling beetles with diverse ecological roles as predators. Research on certain genera, particularly Pterostichus, has revealed complex life history patterns including iteroparity, flexible breeding periods, and responses to environmental conditions such as drought.
Pterostichus
Blackclock Ground Beetles
Pterostichus is a large genus of ground beetles (Carabidae) in the subfamily Harpalinae, comprising over 1,200 species with a Holarctic distribution. These beetles are primarily predatory and are commonly found in ground-level habitats, often beneath rocks and debris. The genus exhibits considerable ecological diversity, with species showing varied substrate preferences ranging from sandy soils to subterranean environments.
Selenophorus breviusculus
Selenophorus breviusculus is a ground beetle in the family Carabidae, described by George Henry Horn in 1880. It belongs to the genus Selenophorus, a group of nocturnal, soil-dwelling beetles commonly known as false bombardier beetles. The species is recorded from the United States.
Selenophorus chaparralus
Selenophorus chaparralus is a ground beetle species described by Purrington in 2000. It belongs to the genus Selenophorus, a group of nocturnal ground beetles within the family Carabidae. The species epithet 'chaparralus' suggests an association with chaparral vegetation, a type of Mediterranean scrubland found in parts of western North America. As a recently described species with limited observation records, much of its biology remains undocumented.
Selenophorus fabricii
Selenophorus fabricii is a species of ground beetle in the family Carabidae, described in 2017. The species is known from the Caribbean region, including the Cayman Islands, Hispaniola, and the Lesser Antilles. As a member of the genus Selenophorus, it belongs to a diverse group of small to medium-sized ground beetles commonly found in tropical and subtropical regions. Very little is known about the specific biology or ecology of this recently described species.
Selenophorus hylacis
Selenophorus hylacis is a species of ground beetle in the family Carabidae. It was described by Thomas Say in 1823. The species occurs in North America, with records from both the United States and Canada. Like other members of its genus, it is a nocturnal ground-dwelling beetle.
Selenophorus mexicanus
Selenophorus mexicanus is a ground beetle species in the family Carabidae, described by Putzeys in 1878. It belongs to the genus Selenophorus, a group of nocturnal carabid beetles commonly known as false bombardier beetles or night-stalking tiger beetles. The species is native to Central America and southern Mexico.
Stenocrepis tibialis
Stenocrepis tibialis is a ground beetle species in the family Carabidae, described by Chevrolat in 1834. It has a broad Neotropical distribution extending into the southern United States. The species occurs in diverse habitats ranging from Caribbean islands to South American mainland regions.
Stenolophina
seedcorn beetles (for genus Stenolophus)
Stenolophina is a subtribe of ground beetles in the family Carabidae, comprising approximately 9 genera and at least 50 described species. The subtribe includes the genus Stenolophus, commonly known as seedcorn beetles. Members are small to medium-sized carabids found in diverse terrestrial habitats.
Stenolophus binotatus
Stenolophus binotatus is a ground beetle species in the family Carabidae. It occurs in North America, with records from the United States. The species has been documented in blacklighting surveys in Kansas during early spring. It belongs to the genus Stenolophus, commonly known as seedcorn beetles.
Synuchus impunctatus
Synuchus impunctatus is a ground beetle species in the family Carabidae, described by Thomas Say in 1823. It belongs to the subfamily Platyninae (sometimes referenced as Harpalinae in older literature) and is part of the diverse genus Synuchus, which contains numerous similar-looking species. The species is documented from Canada and the United States.
Trichotichnus fulgens
Trichotichnus fulgens is a ground beetle species in the family Carabidae, originally described by Csiki in 1932. The species is currently considered a synonym of Trichotichnus nitidulus according to GBIF taxonomy. It is recorded from North America, specifically Canada and the United States. As a member of the tribe Harpalini, it belongs to a diverse group of ground beetles commonly found in terrestrial habitats. The genus Trichotichnus contains multiple species distributed across the Holarctic region.
