Pterostichus menetriesii
Pterostichus menetriesii is a species of woodland ground beetle in the family Carabidae. It is endemic to North America, with records from the United States. The species belongs to the large genus Pterostichus, which comprises numerous ground beetle species distributed across the Northern Hemisphere.
Pterostichus morionides
woodland ground beetle
Pterostichus morionides is a species of ground beetle in the family Carabidae, described by Chaudoir in 1868. It is found in North America, where it inhabits woodland habitats. Like other members of the genus Pterostichus, it is a ground-dwelling beetle, though specific ecological details remain limited in published literature.
Pterostichus putus
Pterostichus putus is a ground beetle species in the family Carabidae, described by Casey in 1913. It belongs to the large genus Pterostichus, which comprises numerous species of predatory beetles distributed primarily in the Northern Hemisphere. The species is known from the United States and is part of the diverse North American carabid fauna. Like other members of its genus, it is likely a ground-dwelling predator, though specific ecological details remain poorly documented.
Pterostichus subacutus
Pterostichus subacutus is a species of ground beetle in the family Carabidae. It is found in North America. The species belongs to the large genus Pterostichus, which comprises numerous woodland-dwelling carabid beetles.
Sanfilippodytes brumalis
Sanfilippodytes brumalis is a small predaceous diving beetle in the family Dytiscidae, described by Brown in 1930. The species belongs to the subfamily Hydroporinae, a group of generally small dytiscids. It occurs in northern North America, with records from Labrador and Québec in Canada. As a member of Dytiscidae, it is aquatic and predatory, though specific natural history details remain poorly documented.
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.
Sericoda obsoleta
Sericoda obsoleta is a species of ground beetle in the family Carabidae, occurring in North America. It is one of several species in the genus Sericoda, which are generally associated with riparian and wetland habitats. The species was described by Thomas Say in 1823. Available information on this species is limited, with most sources providing only basic taxonomic and distributional data.
Trechus schwarzi saludae
Trechus schwarzi saludae is a subspecies of ground beetle in the family Carabidae, described by Barr in 1979. It belongs to the large genus Trechus, which comprises numerous ground beetle species primarily found in temperate regions. As a subspecies of T. schwarzi, it represents a geographically restricted population with presumably distinct morphological characteristics that warranted subspecific recognition. The species epithet 'schwarzi' honors a person, likely an entomologist or collector, while 'saludae' refers to a geographic locality.
Vatellus mexicanus
Vatellus mexicanus is a diving beetle species in the family Dytiscidae, subfamily Hydroporinae, and tribe Vatellini. First described by Sharp in 1882, this species is distributed across Middle America and North America. As a member of the Vatellini, it belongs to a group of small to minute diving beetles often associated with riparian habitats. The genus Vatellus contains species that are typically found in tropical and subtropical regions.
