Pentalobus is a genus of beetles in the family Passalidae. [1]
The sap beetles, also known as Nitidulidae, are a family of beetles.
Passalidae is a family of beetles known variously as "bessbugs", "bess beetles", "betsy beetles" or "horned passalus beetles". Nearly all of the 500-odd species are tropical; species found in North America are notable for their size, ranging from 20 to 43 mm, for having a single "horn" on the head, and for a form of social behavior unusual among beetles.
John Lawrence LeConte MD was an American entomologist, responsible for naming and describing approximately half of the insect taxa known in the United States during his lifetime, including some 5,000 species of beetles. He was recognized as the foremost authority on North American beetles during his career, and has been described as "the father of American beetle study".
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.
Staphylinoidea is a superfamily of beetles. It is a very large and diverse group with worldwide distribution.
Cryptophagidae is a family of beetles with representatives found in all biogeographic realms. Members of this family are commonly called silken fungus beetles and both adults and larvae appear to feed exclusively on fungi although in a wide variety of habitats and situations, such as rotting wood and shed animal fur and feathers. These beetles vary from about 1 to 11 millimeters long, and usually have an oval body shape with a slight "waist".
Hydraenidae is a family of very small aquatic beetles, sometimes called "Minute moss beetles", with a worldwide distribution. They are around 0.8 to 3.3 mm in length. The adults store air on the underside of the body as well as beneath the elytra which allows them to crawl underwater, often on the underside of the water surface tension, though they cannot swim. Some species have gills that effectively allow them to stay underwater indefinitely. Larvae vary from being fully terrestrial, to being aquatic at least in their earliest instars. The diet of hydraenid larvae and adults is thought to consist of algae, spores and other plant matter. At least some hydraenid adults use stridulation to communicate. There are around 1,300 species in 42 genera.
Melolonthinae is a subfamily of the scarab beetles. It is a very diverse group; distributed over most of the world, it contains over 11,000 species in over 750 genera. Some authors include the scarab subfamilies Euchirinae and Pachypodinae as tribes in the Melolonthinae.
Diplogyniidae is a family of parasitic mites belonging to the order Mesostigmata. Many are parasites on beetles but some live on larger animals.
Melyridae are a family of beetles of the superfamily Cleroidea.
Dysoptus is a genus of moths in the family Arrhenophanidae.
Hydrochus is the only living genus of beetle in the family Hydrochidae, which belongs to the superfamily Hydrophiloidea, and was formerly treated as a subfamily of Hydrophilidae. Hydrochus includes about 180 species, which are found worldwide. The name "Hydrochus" has also been used for a fly genus in the family Dolichopodidae, but this is a junior subjective synonym of the genus Rhaphium.
Trogossitidae, also known as bark-gnawing beetles, are a small family in the superfamily Cleroidea. Many taxa formerly within this family have been removed to other families, such as Lophocateridae, Peltidae, Protopeltidae, Rentoniidae, and Thymalidae. Members of the family are generally predatory and/or feed on fungi, both in adult and larval stages, and are generally associated with wood, being found under bark or inside bored tunnel galleries. There are about 400 species in 25 genera in the family under the new, restricted circumscription, as opposed to 600 species in over 50 genera in the old definition. The oldest fossil assignable to the modern, more restricted definition of the family is Microtrogossita from the mid-Cretaceous Burmese amber of Myanmar, which has close affinities to the Trogossitini, indicating that the family had already considerably diversified by this time.
Monkey beetles are scarab beetles, a group of around 70 genera and 850 described species within the tribe Hopliini. The placement of this tribe within the family Scarabaeidae is uncertain between Melolonthinae and Rutelinae. Many species visit flowers for pollen and nectar, or browse on the petals. The beetles are important pollinators of Aizoaceae and Asteraceae in grazed and ungrazed areas, as well as many others.
Agapanthiini is a tribe of longhorn beetles of the subfamily Lamiinae.
Megasternini is a tribe of water scavenger beetles in the family Hydrophilidae. There are at least 70 described species in Megasternini.
Chalepini is a tribe of leaf beetles in the family Chrysomelidae. There are at least 50 genera and 830 described species in Chalepini.
Pentalobus kaupi is a beetle species of the genus Pentalobus of the family Passalidae. It occurs in São Tomé and Príncipe. The species was described in 2005.
Ampedus is a genus of click beetles in the family Elateridae. There are currently 461 recognized species of Ampedus beetles. It has a cosmopolitan distribution, but is found mostly in the Holarctic region, primarily in North America, Europe, and Asia. The oldest known fossil from this genus was found in Eocene Baltic amber, estimated to be from 38.0 to 33.9 million years ago.
