Cucujoidea
Guides
Anthonaeus
Anthonaeus is a genus of short-winged flower beetles in the family Kateretidae. The genus was established by Horn in 1879 and contains a single described species, A. agavensis. Members of this genus are small beetles with reduced hindwings, characteristic of their family.
Brontinae
Brontinae is a subfamily of beetles in the family Silvanidae, established by Blanchard in 1845. These beetles are part of the superfamily Cucujoidea, a diverse group of small to medium-sized beetles often associated with stored products, decaying plant matter, or fungal habitats. The subfamily contains multiple genera and is primarily distinguished by morphological features of the head and antennae. Brontinae species are found across various regions but are not as extensively studied as some other silvanid groups.
Caenoscelis
Caenoscelis is a genus of silken fungus beetles in the family Cryptophagidae, established by C.G. Thomson in 1863. The genus comprises approximately 19 described species. Members are classified within the tribe Caenoscelini. These beetles are part of the diverse cucujoid beetle fauna associated with fungal habitats.
Cryptophagidae
silken fungus beetles
Cryptophagidae is a family of small beetles commonly known as silken fungus beetles. Adults and larvae feed exclusively on fungi across diverse habitats including rotting wood and shed animal fur and feathers. The family contains approximately 600 species in 60 genera divided into two subfamilies: Atomariinae and Cryptophaginae. Body size ranges from 1 to 11 millimeters with an oval shape and slight waist.
Kateretidae
Short-winged Flower Beetles
Kateretidae, commonly known as short-winged flower beetles, is a family of small beetles in the superfamily Cucujoidea. The family contains 10 extant and 4 extinct genera with at least 40 described species distributed worldwide except New Zealand. Adults feed on flowers (anthophagous), while larvae develop within flower corollas where they consume pollen (spermatophagous). The family has been the subject of taxonomic revision, with several Cretaceous amber fossils originally described as kateretids subsequently reclassified to other families.
Mecomycter majeri
Mecomycter majeri is a species of beetle in the family Mauroniscidae, a small family of soft-bodied plant beetles (Cucujoidea). The species is known from a single iNaturalist observation, indicating it is either rare, poorly sampled, or has a restricted distribution. Members of Mauroniscidae are generally associated with decaying plant material and fungal habitats.
Passandridae
Parasitic Flat Bark Beetles
Passandridae, commonly called parasitic flat bark beetles, is a small family of beetles in the superfamily Cucujoidea. The family contains approximately 109 described species in nine genera. Adults are small to moderately sized beetles (3–35 mm) with heavily sclerotized bodies, typically brown or black in coloration. The family is notable for having larvae that are exclusively ectoparasitic on the immature stages of other beetles and Hymenoptera, making them one of very few beetle families with this lifestyle.
Phalacridae
shining flower beetles
Phalacridae is a family of small beetles commonly known as shining flower beetles. The family contains approximately 638 species in 52 genera worldwide. Adults are typically found on composite flowers, particularly Asteraceae, where they feed on pollen and floral tissues. Most species are fungivorous, though some feed on flower heads and developing seeds. The family has a fossil record extending to the Early Cretaceous.
Silvanidae
Silvan Flat Bark Beetles, Silvanid Flat Bark Beetles
Silvanidae is a family of small beetles in the superfamily Cucujoidea, comprising approximately 68 genera and 500 described species. Members are found on all continents except Antarctica, with highest diversity in the Old World tropics. The family is divided into two subfamilies: Brontinae (larger, loosely jointed beetles with long antennae and mandibular mycangia) and Silvaninae (smaller beetles with closed procoxal cavities). While many species inhabit subcortical environments under bark, several genera have become economically significant stored product pests.
Silvanus
Silvanus is a genus of beetles in the family Silvanidae, first described by Latreille in 1804. These insects belong to the superfamily Cucujoidea within the suborder Polyphaga. The genus is part of a group commonly known as silvanid or flat bark beetles, though specific ecological details for Silvanus itself are not well documented in the provided sources.
Telephanus
Telephanus is a genus of beetles in the family Silvanidae, first described by Erichson in 1846. The genus contains over 100 described species distributed primarily in the Americas, with records extending from North America through Central America to South America. Species in this genus are classified within the tribe Telephanini, subfamily Brontinae. The genus has been subject to taxonomic revision, with many species described by Grouvelle, Nevermann, and Sharp in the late 19th and early 20th centuries.
