The family Archeocrypticidae is a small group of beetles with no vernacular common name, though recent authors have coined the name cryptic fungus beetles. Adults and larvae seems to be saprophagous and are often found in plant litter. Worldwide, about 10 genera and 50 species are found, most species are pantropical. Enneboeus caseyi has been recorded from the American South, Central America, and Mexico. About 20 species are found in Australia, in the genera Enneboeus,Australenneboeus and Gondwanenneboeus,Archeocrypticus,Falsoplatydema, Nothenneboeus, Sivacrypticus and Wattianus. They are largely absent from the Palearctic and Nearctic regions.
The family Mycteridae is a small group of tenebrionoid beetles with no vernacular common name, though recent authors have coined the name palm and flower beetles. The family Mycteridae is distributed worldwide. There are about 30 genera and 160 species in three subfamilies Mycterinae, Hemipeplinae and Lacconotinae (=Eurypinae). These 3 subfamilies are extremely diverse in appearance and are sometimes difficult to have a present diagnosis of the adults at the family level. About 20 species are found in Australia, species of three genera are found in North America The larvae are generally flattened and typically inhabit the spaces between leaves or the bases of fronds, where they appear to consume fungi.
Prostomidae is a family of beetles with no vernacular common name, though recent authors have coined the name jugular-horned beetles. They are often found in dead wood. The family consist of two extant genera with about 20 species. Prostomis americanus is known from North America. Other species of Prostomis are found in Europe, Africa, the Pacific region and East Asia. Species of Dryocora are known from New Zealand, Australia and Tasmania.
The family Scraptiidae is a small group of tenebrionoid beetles sometimes called false flower beetles. There are about 400 species in 30 genera with a world-wide distribution. The adults are found on flowers, sometimes in large numbers, but are also found on foliage. The larvae are typically found under the bark of dead trees. The oldest fossils of the group date to the Eocene.
Agyrtidae, or primitive carrion beetles, are a small family of beetles belonging to Staphylinoidea. They are found in mostly temperate areas of the Northern Hemisphere and in New Zealand.
The Ommatidae are a family of beetles in the suborder Archostemata. The Ommatidae are considered the extant beetle family that has most ancestral characteristics. There are only seven extant species, confined to Australia and South America. However, the geographical distribution was much wider during the Mesozoic spanning across Eurasia and Australia, suggesting that they were widespread on Pangea. So far, over 26 extinct genera containing over 170 species of these beetles have been described. Three extant genera have been assigned to this family: Omma,Tetraphalerus and Beutelius. The family is considered to be a subfamily of Cupedidae by some authors, but have been found to be more closely related to Micromalthidae in molecular phylogenies. A close relationship with Micromalthidae is supported by several morphological characters, including those of the mandibles and male genitalia. Due to their rarity, their ecology is obscure, it is likely that their larvae feed on deadwood.
Discolomatidae is a family of beetles in the superfamily Coccinelloidea. It contains approximately 400 species in 16 genera, which are found mostly found in tropical regions, being largely absent from temperate regions. They have generally been found associated with decaying vegetation or fungi, and are therefore assumed to be fungivorous, though some species are associated with ants (myrmecophily). The larvae have unusual flattened sclerotised bodies, with heads that are concealed from above.
Lamingtonium is the only genus in the family Lamingtoniidae, of the beetle superfamily Cucujoidea. It contains three species endemic to Australia. The holotype of the type species was collected on at Lamington National Park, Binna Burra, Queensland under the bark of a dead tree. The adults and larvae of two species have been found associated with basidiocarps of fungi belonging to the family Polyporaceae.
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.
Pterogeniidae is a family of beetles belonging to the supefamily Tenebrionoidea. They are found in South Asia, Southeast Asia, China, New Guinea and the Solomon Islands. Adults and larvae have been found associated with the fruiting bodies of polypore fungi, although adults can also be found in litter and debris.
Salpingidae or narrow-waisted bark beetles is a family of beetles in the superfamily Tenebrionoidea. The species are small, about 1.5 – 7 mm in length. The family is globally distributed and consists of about 45 genera and 300 species, which are generally found in the temperate regions of both hemispheres. The family is mainly associated with plants as well as with ascomycete and hyphomycete fungi. Some members of the family are associated with unusual habitats, like Aegialites and Antarcticodomus, which are found in coastal areas including the intertidal zone, with former feeding on algae.
Trachelostenus is a genus of beetles belonging to Tenebrionoidea. It is native to the Valdivian forests of Chile, and has at least two species, T. inaequalis (Solier) and T. fascicularis (Philipp). It was historically considered the only member of the family Trachelostenidae, but a 2015 study sunk the genus into the tenebrionid subfamily Tenebrioninae.
Byrrhidae, the pill beetles, is a family of beetles in the superfamily Byrrhoidea. They are generally found in damp habitats within cooler-high latitude regions of both hemispheres. Most byrhhids feed on moss, lichens and algae, though some species feed on vascular plants. The oldest undoubted record of the family is Lidryops from the earliest Late Cretaceous Charentese amber of France, with other less certain records going back to the Middle Jurassic, but these possibly belong to Byrrhoidea. There around 500 extant species in 40 genera.
The Brachypsectridae are a family of beetles commonly known as the Texas beetles. There are only two extant genera, Brachypsectra and Asiopsectra. Brachypsectra has a cosmopolitan distribution, mostly in arid regions, while Asiopsectra is found in Central Asia and the Middle East.
Decliniidae is a family of beetles belonging to Scirtoidea. It contains the single genus Declinia with two species, D. relicta and D. versicolor, found in the Russian Far East and Japan, respectively. Little is known of their ecology, and their larvae are unknown. Specimens of D. relicta were found with pollen grains in their gut.
Acanthocnemus nigricans is a species of cleroid beetle, the only species in the genus Acanthocnemus and the family Acanthocnemidae. Originally native to Australia, the species has spread in modern times to numerous parts of the world, including Europe, Africa, India and Southeast Asia. The insects are pyrophilous, congregating around areas of recently burned wood, being attracted to chemicals found in wood smoke. They have specialised infrared receptors located on the thorax close to the head, used to detect heat. Their life cycle is poorly understood, though mating and egg-laying likely occurs within ash. The larvae are possibly saprophagous.
Mallodrya is a genus of synchroa bark beetles in the family Synchroidae. There is one described species in Mallodrya, M. subaenea.
Synchroa is a genus of synchroa bark beetles in the family Synchroidae. There are about six described species in Synchroa.
Myrabolia is the only genus in the beetle family Myraboliidae in the superfamily Cucujoidea. It has about 13 species, found in Australia. Adults and possibly larvae live under the bark of Eucalyptus trees.
Binburrum articuno is a species of beetle which in the taxonomy field is classified under the genus Binburrum. It exists only in Australia. It is named after the fictional animal known as Articuno from the pop culture franchise known as Pokemon.It was named along side other beetles from the same genus by Darren Pollock and Yun Hsiao when they found the beetles in the Australian National Insect Collection, and those beetles are Binburrum moltres and Binburrum zapdos and because of their names being based of a very popular franchise it saw above average media coverage. The reason for this naming convention is because Moltres and Zapdos are also from the video game franchise Pokemon and in the franchise, they are correlated because they are part of the Legendary Bird Trio centered around the elements of electricity, ice, and fire.
