Philonthus aurulentus
Philonthus aurulentus is a species of rove beetle in the family Staphylinidae, first described by Horn in 1884. The specific epithet 'aurulentus' suggests a golden or gold-colored appearance. The species occurs in western North America, with records from the Canadian provinces of Alberta, British Columbia, Manitoba, Northwest Territories, and Saskatchewan, and from the western United States including Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, North Dakota, Nebraska, Oregon, Utah, Washington, and Wyoming. Like other members of the genus Philonthus, it is likely a predatory beetle associated with decaying organic matter, though specific ecological details remain poorly documented.
Philonthus cautus
Philonthus cautus is a rove beetle in the family Staphylinidae, described by Erichson in 1840. As a member of the large genus Philonthus, it shares the characteristic shortened elytra and predatory habits typical of staphylinid beetles. The species is known from the southeastern United States, with records from Alabama through Texas and north to Maryland and Virginia. Like other Philonthus species, it likely inhabits decaying organic matter where it preys on other small invertebrates.
Philonthus hepaticus
Philonthus hepaticus is a large rove beetle in the family Staphylinidae, first described by Erichson in 1840. It is one of the larger species within the genus Philonthus. The species has a broad distribution across the Americas, with records from Canada through Argentina and the Caribbean, and has been introduced to Australia and New Zealand. In Canada, it was first documented in British Columbia, with a second record from New Brunswick representing the first eastern Canadian occurrence.
Philonthus neonatus
Philonthus neonatus is a species of rove beetle in the family Staphylinidae, described by Smetana in 1965. It belongs to the large and diverse genus Philonthus, which contains numerous predatory species commonly associated with decaying organic matter, fungi, and other insects. The species is documented from eastern North America, with records spanning Canada and the eastern United States. Like other members of its genus, it is likely predatory, though specific ecological details for this species remain poorly documented.
Philonthus nudus
Philonthus nudus is a rove beetle species in the family Staphylinidae, first described by Sharp in 1874. It belongs to the large genus Philonthus, which contains numerous predatory species associated with various habitats including carrion, fungi, and decaying organic matter. The species has a documented distribution across the Holarctic region, including parts of East Asia and western North America.
Philonthus rectangulus
Philonthus rectangulus is a rove beetle species described by Sharp in 1874. It belongs to the large genus Philonthus within the family Staphylinidae. The species has been documented in southern South America, the Republic of Moldova, and parts of Europe including the Azores islands and the Balkans. As a member of the rove beetle family, it likely exhibits the characteristic shortened elytra and predatory habits typical of the group, though specific ecological details remain poorly documented in available literature.
Philonthus sanguinolentus
A medium-sized rove beetle in the genus Philonthus, characterized by dark coloration with reddish or blood-red markings that give the species its name. Like other members of Staphylinidae, it exhibits the family's distinctive short elytra that leave much of the abdomen exposed. The species has a Palearctic native distribution but has been introduced to North America, where it is established in the Pacific Northwest and parts of Canada.
Philonthus sericinus
Philonthus sericinus is a rove beetle in the family Staphylinidae, described by Horn in 1884. The genus Philonthus comprises predatory beetles commonly found in decaying organic matter and fungi. This species occurs in eastern North America, with records from Canada and the United States. Like other members of its genus, it likely preys on small invertebrates in decomposing substrates.
Philonthus sessor
Philonthus sessor is a rove beetle in the family Staphylinidae, described by Smetana in 1965. It belongs to the large and diverse genus Philonthus, which contains numerous predatory species associated with decaying organic matter, fungi, and carrion. The species is known from northeastern North America, with records from Canada and the northeastern United States. Like other members of its genus, it likely functions as a generalist predator in decomposing habitats.
Philonthus thoracicus
Philonthus thoracicus is a species of rove beetle in the family Staphylinidae. As a member of the genus Philonthus, it is part of a large group of predatory beetles commonly associated with decomposing organic matter. The species occurs across much of North America, with documented records from Canada and numerous U.S. states. Like other Philonthus species, it likely inhabits carrion, dung, and other nutrient-rich decaying substrates where it preys on small invertebrates.
Philonthus triangulum
Philonthus triangulum is a rove beetle in the family Staphylinidae, described by Horn in 1884. It belongs to a large genus of predatory beetles commonly found in decomposing organic matter and other habitats where small invertebrate prey is abundant. Like other members of Philonthus, it exhibits the characteristic shortened elytra and exposed abdominal segments typical of rove beetles. The species is recorded from western North America including the Pacific Northwest and southwestern United States, extending into Mexico.
