Beetle subfamilies

thumb|Mating Rhizotrogus marginipes ([[Melolonthini), male on top – note sexually dimorphic antennae]] Melolonthinae is a subfamily of the scarab beetles (family Scarabaeidae). 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.

Tenebrioninae is the largest subfamily of the darkling beetles (Tenebrionidae), containing flour beetles, among others. Tenebrioninae contains more than 20 tribes.

The Lucaninae comprise the largest subfamily of the stag beetles (Lucanidae).

The beetle subfamily Curculioninae is part of the weevil family Curculionidae. It contains over 23,500 described species in 2,200 genera, and is therefore the largest weevil subfamily. Given that the beetle order (Coleoptera) contains about one-quarter of all known organisms, the Curculioninae represent one of the – if not the – most successful radiations of terrestrial Metazoa.

The Leptotyphlinae are a subfamily of the Staphylinidae, rove beetles. They are very small, less than 1.8 mm long, and are eyeless and wingless. These beetles appear to have seven abdominal segments, and 3-3-3 is their tarsal formula. They are found in leaf litter or deep soil, possibly as predators of mites, collembola, and other soil arthropods. Nine genera and 13 species are known from North America, in western states and Florida, but they may be more widespread.

Pimeliinae is a subfamily of beetles in the family Tenebrionidae.

Lixinae is a subfamily of true weevils, included in the Molytinae in many older treatments. They are mainly root feeders, although some develop in flower buds or stems. Several species are used in biological control of invasive weeds, namely knapweeds (Centaurea).

Steninae is a subfamily of Staphylinidae.

Polycestinae is a subfamily of beetles in the family Buprestidae: known as "jewel beetles".

The Micropeplinae are a subfamily of the Staphylinidae, rove beetles. Their antennae have 9 segments with single-segmented clubs. The tarsal formula is 4-4-4 (appearing as 3–3–3). They are found in leaf litter, near lake shores and marshy areas, in mammal and bird nests, probably as saprophages or mold feeders. In North America, two genera are known Kalissus LeConte 1874 (British Columbia and Washington) and Micropeplus Latreille, with 14 widespread species.

Tachyporinae is a subfamily of rove beetle. Their common name is crab-like rove beetles. They are generally small, roughly 2.4 to 5 millimeters.

The Osoriinae are a subfamily of beetles in the family Staphylinidae, the rove beetles. They are found mainly in tropical and subtropical regions.

Thorictinae is a subfamily of beetles in the family Dermestidae, containing the following genera:

Agabinae is a subfamily of predaceous diving beetles in the family Dytiscidae. There are 9 extant genera and more than 460 described species in Agabinae. thumb|Platynectes kashmiranus

The Aesalinae are a subfamily of the stag beetle (Lucanidae) genera: based on the type genus Aesalus and included in William Sharp Macleay's first major work of 1819.

Piestinae are a subfamily of Staphylinidae.

Dasytinae is a subfamily of soft-wing flower beetles, beetles of the family Melyridae, historically sometimes treated as a separate family, "Dasytidae".

The Oxytelinae are a subfamily of the Staphylinidae, rove beetles. There are about 20 genera and at least 320 described species in Oxytelinae.

Ptiliinae is the largest subfamily of feather-winged beetles (family Ptilidae). About 80% of the described genera of these very tiny beetles are contained herein; however, many more genera and species await description.

The Habrocerinae are a subfamily of the Staphylinidae, rove beetles.

Lycoperdininae is a beetle subfamily in the family Endomychidae.

The Lampriminae are a relatively small subfamily of southern hemisphere stag beetle (Lucanidae) genera: based on the type genus Lamprima and included in William Sharp Macleay's first major work of 1819.

Colymbetinae is a subfamily of predaceous diving beetles in the family Dytiscidae. There are about 11 genera and at least 130 described species in Colymbetinae. thumb|Rhantus suturellus

Sticholotidinae was a subfamily of beetles in the family Coccinellidae (lady beetles). Phylogenetic analysis found the subfamily is not a clade and thus invalid.

The Microweiseinae are a subfamily of Coccinellidae, the lady beetles. Members of the Microweiseinae subfamily are often found to have their head curved down, closely held against their ventral side. In comparison to common garden coccinellids, ladybugs, the Microweiseinae lack the important bright markings that serve as warnings to potential predators.

Attageninae was a subfamily of beetles in the family Dermestidae. In 2003, that beetle species was reduced in rank and is now treated as the tribe Attagenini.

Tillinae is a subfamily of beetles in the family Cleridae, the checkered beetles.

Orphilinae is a subfamily of beetles that includes three genera: Orphilodes, Orphilus and Ranolus. It was described by John Lawrence LeConte in 1861.

Apoderinae is a subfamily of leaf rolling weevils in the beetle family Attelabidae. There are at least 20 genera and more than 650 described species in Apoderinae, found in Europe, Asia, and Africa.

Oxycoryninae are subfamily of primitive weevils of the family Belidae, but sometimes treated as a distinct family Oxycorynidae. Like in other belids, their antennae are straight, not elbowed as in the true weevils (Curculionidae), and their larvae feed on the wood of diseased or dying plants or on deadwood or fruits; they tend to avoid healthy plants.

Laccophilinae is a subfamily of ground and water beetles in the family Dytiscidae. There are at least 410 described species in Laccophilinae.

Sphaeridiinae is a subfamily of water scavenger beetles (insects in the family Hydrophilidae). Some species live in fresh water as both larvae and adults.

Attelabinae is a subfamily of leaf-rolling weevils in the beetle family Attelabidae. There are at least 20 genera and more than 690 described species in Attelabinae. thumb|Homoeolabus analis thumb|Leaf roll containing an egg of Attelabinae sp.

Stenochiinae is a subfamily of darkling beetles in the family Tenebrionidae. There are more than 390 genera in Stenochiinae. thumb|Xylopinus saperdoides

The Dinoderinae comprise a subfamily of the beetle family Bostrichidae. There are five to seven genera. They live in wood. Some species are known as pests of wood-based and other stored products.

Latridiinae is a subfamily of tiny, little-known beetles in the family Latridiidae.

The beetles of the subfamily Pilipalpinae belong to the small family of fire-coloured beetles (Pyrochroidae). They are found only in the Southern Hemisphere, occurring in Australia, Chile, Madagascar and New Zealand. Most of the genera are small or even monotypic, but it is highly likely that a number of undescribed species exist.

Lycinae is a subfamily of net-winged beetles in the family Lycidae. thumb|Lycus loripes

The Photurinae are a subfamily of the Lampyridae (fireflies). They are among the flashing (as opposed to continuously glowing) fireflies known as "lightning bugs" in North America. The anterior ends of the elytra sit higher than the pronotum, giving the Photurinae a characteristic "hunched" posture.

Lemodinae is a beetle subfamily in the family Anthicidae.

thumb | right | alt=Image of Agyrtes | Image of Agyrtes Agyrtinae is a subfamily in the family Agyrtidae. It contains four genera: Agyrtes (the type genus of the subfamily and the family), Ecanus, Ipelates and Lyrosoma.
