Kenocoelus is a genus of rove beetles (the family Staphylinidae) containing a number of species, all endemic to New Zealand. [1] [2] It is part of the Trichonychini tribe, in the Pselaphinae subfamily of Staphylinidae.
These are small beetles (body size 1.46–1.76mm) with short antennae and small, ovoid eyes. [3] They can be distinguished from similar genera of Trichonychini from their small size, short first antennal segment and pronotum without sulci.
Some species of Kenocoelus have been repeatedly collected within Huberia ant nests suggesting that the beetles are inquilines although interactions between the species have not been directly observed. [3]
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 the second largest family in the beetle order, after the true weevils (Curculionidae), which also makes in one of the largest families 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.
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae, Helophoridae, Hydrochidae, and Spercheidae. While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae.
Dynastinae or rhinoceros beetles are a subfamily of the scarab beetle family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1500 species and 225 genera of rhinoceros beetles are known.
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.
Jacobsoniidae are a family of tiny beetles belonging to Staphylinoidea. The larvae and adults live under bark, in plant litter, fungi, bat guano and rotten wood. There are around 28 described species in three genera:
Silvanidae, "silvan flat bark beetles", is a family of beetles in the superfamily Cucujoidea, consisting of 68 described genera and about 500 described species. The family is represented on all continents except Antarctica, and is most diverse at both the generic and species levels in the Old World tropics.
The Chalcodryidae are a family of beetles in the superfamily Tenebrionoidea. It contains at least five species in two genera Chalcodrya and Philpottia, which are endemic to New Zealand. They are generally found associated with moss or lichen covered branches, with the larvae having been found to be associated with dead twigs. It is thought that they are noctural, feeding on lichen and other plant material at night. The genera Sirrhas and Onysius, formerly placed in this family, have subsequently been transferred to Promecheilidae.
Sagola is a genus of beetles in the Staphylinidae family. It was first described by the entomologist David Sharp in 1874. The New Zealand species within the genus were revised in 2014 with numerous new species being described.
Articerodes is a genus of beetles belonging to the family Staphylinidae. Species of Articerodes have been found within the Palearctic, Oriental, and Afrotropical biogeographic realms. In the Oriental realm, four species were known, all from islands. The first examples found on the Asian mainland were discovered and described in 2008 by Dr. Shuhei Nomura, Dr. Watana Sakchoowong and Dr. Jariya Chanpaisaeng.
Eumolpini is a tribe of leaf beetles in the subfamily Eumolpinae. It is the largest tribe in the subfamily, with approximately 170 genera found worldwide. Members of the tribe almost always have a longitudinal median groove on the pygidium, which possibly helps to keep the elytra locked at rest. They also generally have a subglabrous body, as well as appendiculate pretarsal claws.
Thoracophorus costalis, the furrowed rove beetle, is a species of unmargined rove beetle in the family Staphylinidae. It is found in Central America and North America.
Thoracophorus is a genus of unmargined rove beetles in the family Staphylinidae. There are more than 20 described species in Thoracophorus.
Silusida is a genus of rove beetles in the family Staphylinidae. There is one described species in Silusida, S. marginella.
Ctenisis phylanderi is a species of ant-loving beetle in the family Staphylinidae. It is found in North America.
Ctenisis is a genus of ant-loving beetles in the family Staphylinidae. There are at least two described species in Ctenisis.
Promecheilidae is a family of beetles in the superfamily Tenebrionoidea. Perimylopidae is considered a synonym. They are found in southern South America and associated archipelagos like South Georgia and the Falklands, New Zealand and Tasmania. Some species are associated tree ferns and moss-covered dead wood, and other forested habitats, while others are associated with peat bogs, grasslands and coastal habitats. They are probably phytophagus, feeding on lichen, moss, and other plant material.
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.
Telegeusinae is a small subfamily of beetles in the family Omethidae recognizable by enlarged palpi found in males. Though relatively rare, males are sometimes found in large numbers in black light traps. Females are not known in this group, but it is theorized that females are larviform as found in many closely related taxa.
