Dasycerinae is a subfamily of rove beetles. [1] Dasycerinae currently only contains 1 extant genus and 3 extinct genera. [2]
There are currently 4 described genera in Dasycerinae: [2]
(† = extinct)
They have antennae with 11 segments and trisegmented antennal clubs. The tarsi have three segments, and the elytra cover or nearly cover the entire abdomen.
These beetles inhabit moist broadleaf forest litter. [3] Eastern species are wingless with small eyes; dissected females have only been found with a single egg. They are known to occur on fruiting fungi, but may not specifically feed on them.
The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus Leehermania proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.
Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae.
Pselaphinae are a subfamily of beetles in the family Staphylinidae, the rove beetles. The group was originally regarded as a separate family named Pselaphidae. Newton and Thayer (1995) placed them in the Omaliine group of the family Staphylinidae based on shared morphological characters.
Staphylinoidea is a superfamily of beetles. It is a very large and diverse group with worldwide distribution.
Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily.
The Paederinae are a subfamily of the Staphylinidae, rove beetles. The Paederinae include two tribes, Paederini and Pinophilini. This insect is commonly known as Tomcat.
The Aleocharinae are one of the largest subfamilies of rove beetles, containing over 12,000 species. Previously subject to large-scale debate whether the subfamily deserved the familial status, it is now considered one of the largest subfamilies of rove beetles.
The Empelinae are a subfamily of rove beetles ; their biology is virtually unknown. Their anatomy and ecology resemble many rove beetles.
The Euaesthetinae are a subfamily of the Staphylinidae (Coleoptera). These rove beetles have slender antennae with two or three apical antennomeres forming a loose club. The tarsi have 4-4-4 or 5-5-5 segments. They are found in forest litter. Five genera and 22 species known from North America.
The Habrocerinae are a subfamily of the Staphylinidae, rove beetles.
The Leptotyphlinae are a subfamily of the Staphylinidae, rove beetles. They are very small, less than 1.8 mm long, and are eyeless and wingless. These beetles appear to have seven abdominal segments, and 3-3-3 is their tarsal formula. They are found in leaf litter or deep soil, possibly as predators of mites, collembola, and other soil arthropods. Nine genera and 13 species are known from North America, in western states and Florida, but they may be more widespread.
The Micropeplinae are a subfamily of the Staphylinidae, rove beetles. Their antennae have 9 segments with single-segmented clubs. The tarsal formula is 4-4-4. They are found in leaf litter, near lake shores and marshy areas, in mammal and bird nests, probably as saprophages or mold feeders. In North America, two genera are known Kalissus LeConte 1874 and Micropeplus Latreille, with 14 widespread species.
Eusphalerum is a genus of ocellate rove beetles in the family Staphylinidae. There are at least 130 described species in Eusphalerum.
Anthophagini is a tribe of ocellate rove beetles in the family Staphylinidae. There are at least 20 genera and 20 described species in Anthophagini.
Omaliini is a tribe of ocellate rove beetles in the family Staphylinidae. There are about 12 genera and 19 described species in Omaliini.
Pelecomalium is a genus of ocellate rove beetles in the family Staphylinidae. There are at least three described species in Pelecomalium.
Phloeonomus is a genus of ocellate rove beetles in the family Staphylinidae. There are about eight described species in Phloeonomus.
Thoracophorini is a tribe of unmargined rove beetles in the family Staphylinidae. There are at least three genera and about six described species in Thoracophorini.
Euphaniini is a tribe of spiny-legged rove beetles in the family Staphylinidae. There are at least 8 genera in Euphaniini.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
