The Acroceridae are a small family of odd-looking flies. They have a hump-backed appearance with a strikingly small head, generally with a long proboscis for accessing nectar. They are rare and not widely known. The most frequently applied common names are small-headed flies or hunch-back flies. Many are bee or wasp mimics. Because they are parasitoids of spiders, they also are sometimes known as spider flies.
Colydiinae is a subfamily of beetles, commonly known as cylindrical bark beetles. They have been treated historically as a family Colydiidae, but have been moved into the Zopheridae, where they constitute the bulk of the diversity of the newly expanded family, with about 140 genera worldwide. They are diverse for example in the Australian region, from where about 35 genera are known; in Europe, though, only 20 genera are found and many of these only with few species.
Erotylidae, or the pleasing fungus beetles, is a family of beetles belonging to Cucujoidea containing over 100 genera. In the present circumscription, it contains 6 tribes and 10 subfamilies. In other words, the narrowly circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition sensu lato. There are doubts on the monophyly of lower ranked taxa within Erotylidae, with further phylogenetic studies requiring better sampling and studies of unexplored character sets, for example the metendosternite and penile flagellum, which are generally lacking detailed morphological studies within the Coleoptera literature. The Eroytlina taxonomy is based on traits such as their different colors and not off morphological differences like mouthparts, thorax, and abdominal terminalia (Pecci-Maddalena).
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.
Agonocheila is a genus in the beetle family Carabidae. There are more than 20 described species in Agonocheila.
Rhyzodiastes is a genus of beetles in the family Carabidae, containing the following species:
Omoglymmius is a genus in the ground beetle subfamily Rhysodinae. There are more than 150 described species in Omoglymmius, found on every continent except Antarctica.
Kaveinga is a genus of wrinkled bark beetles in the family Carabidae.
Biphyllus is a genus of beetles in the family Biphyllidae, containing the following species:
Dysmerus is a genus of beetles in the family Laemophloeidae. Restricted to the New World, until recently Dysmerus included only the type species, D. basalis, described from Florida in the late 19th century. A recent revision resurrected two incorrectly synonymized species and recognized an additional 12 new species, so that the genus currently contains 15 species.
Bactridium is a genus of root-eating beetles in the family Monotomidae. There are about 18 described species in Bactridium.
Ancyronyx, commonly known as spider water beetles or spider riffle beetles, is a genus of aquatic riffle beetles from North America, South Asia, China, and Southeast Asia. They are small beetles with extremely long legs ending in strong claws. Both the adults and the larvae are found underwater in the shallow riffles of streams and rivers, clinging to rocks or submerged wood. They feed on algae and decaying wood tissue. The genus contains twenty-one species, eleven of which are endemic to the Philippines.
Paleopanax is an extinct genus of flowering plant in the Ginseng and Ivy family, Araliaceae, containing the single species Paleopanax oregonensis. The species is solely known from the middle Eocene sediments exposed in north central Oregon and was first described from a series of isolated fossil fruits in siltstones.
Rhinolaemus is a genus of beetles in the family Laemophloeidae. Until recently, the genus included only Rhinolaemus maculatus, known from a single specimen collected almost 100 years ago in Fiji. A recent revision, based on newer collections, resulted in the description of a new species from Niue Island, and transferral of a third species from Laemophloeus from Fiji and other island groups.
Callipyrga turrita is a species of beetle in the family Cerambycidae, and the only species in the genus Callipyrga. It was described by Edward Newman in 1842 using a specimen obtained by Rupert Kirk at Woodside near Sydney. This species is endemic to coastal eastern Australia from Townsville in Queensland down to Glenmore in New South Wales. The adult beetles are attracted to light and have been collected on Geijera parviflora and Flindersia xanthoxyla.
Chalcolampra is a genus of leaf beetles. These beetles are widespread from Southeast Asia to Australia and New Zealand, but most common in the southeast of Australia. There are approximately 25 Australian species within this genus. There are also 13 species described from New Zealand, with up to an additional 20 undescribed species from the South Island.
Coccinelloidea is a superfamily of beetles in the order Coleoptera, formerly included in the superfamily Cucujoidea. There are more than 10,000 species in Coccinelloidea, including more than 6000 in the lady beetle family Coccinellidae.
Namunaria is a genus of cylindrical bark beetles in the family Zopheridae, first described by Edmund Reitter in 1882. There are at least two described species in Namunaria.
Bothrideres is a genus of dry bark beetles in the family Bothrideridae. There are about 13 described species in Bothrideres.
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.
