Timarcha is a genus of leaf beetles in the family Chrysomelidae, with more than 100 described species in three subgenera. The most widely known species is T. tenebricosa, the bloody-nosed beetle. All species are black, wingless organisms. Timarcha are herbivorous species, living mostly on plants belonging to Rubiaceae and Plumbaginaceae, although a few can feed on Brassicaceae and Rosaceae. Timarcha is the only member of the tribe Timarchini.
The Donaciinae are a subfamily of the leaf beetles, or Chrysomelidae, characterised by distinctly long antennae. They are found in mainly the Northern Hemisphere, with some species found in the Southern Hemisphere.
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).
Donacia is a large genus of aquatic leaf beetles in the subfamily Donaciinae. Like other members of that subfamily, the beetles have long antennae. They are active and able to fly. Larvae feed on submerged portions of aquatic plants, such as water lilies, and breathe oxygen from plant vessels. Adults live on surface parts of the same plants.
Chrysomela is a genus of leaf beetles found almost throughout the world, but not in Australia. It contains around 40 species, including 7 in eastern and northern Europe. It also includes at least 17 species in North America, including the cottonwood leaf beetle Chrysomela scripta.
Gonioctena is a genus of leaf beetles belonging to the family Chrysomelidae, subfamily Chrysomelinae.
Phratora is a genus of leaf beetles. It is synonymous to Phyllodecta . European Phratora species can be distinguished based on morphology of female genitalia., but they differ little in size and body form and most show metallic coloration.
Colaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 200 species, and it is known from both North and South America. A number of species from this genus are considered to be pests, such as the grape colaspis. Some species are known from the fossil record from the Eocene of Colorado in the United States.
Calligrapha is a genus of large American Chrysomelinae of imprecise taxonomic boundaries. Most species occur in Central and South America.
Neolema is a genus of leaf beetles in the family Chrysomelidae. Eight described species currently are placed in Neolema.
Metachroma is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed from Ontario, Canada to Mendoza, Argentina, including the Antilles. It has also been suggested that the genus extends to the Pacific Islands, though this is not confirmed. There are about 140 described species in Metachroma, 40 of which are found north of Mexico. An extinct species is also known from the Eocene of the United States.
Brachycoryna is a genus of tortoise beetles and hispines in the family Chrysomelidae. There are seven described species in Brachycoryna.
Eumolpini is a tribe of leaf beetles in the subfamily Eumolpinae. It is the largest tribe in the subfamily, with approximately 170 genera found worldwide. Members of the tribe almost always have a longitudinal median groove on the pygidium, which possibly helps to keep the elytra locked at rest. They also generally have a subglabrous body, as well as appendiculate pretarsal claws.
Androlyperus is a genus of skeletonizing leaf beetles in the family Chrysomelidae. There are about five described species in Androlyperus. They are found in North America and Mexico.
Glyptoscelis is a genus of leaf beetles in the subfamily Eumolpinae. There are 38 species of Glyptoscelis described from North, Central and South America. There are also three species of Glyptoscelis known from the West Indies, though they are wrongly placed in the genus. In addition, a single species was described from Hunan, China in 2021.
Megascelis is a genus of leaf beetles in the subfamily Eumolpinae. It is known from both North and South America. There are around 140 described species in Megascelis.
Tymnes is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North America and Central America. There are at least nine described species in Tymnes.
Chrysodinopsis is a genus of leaf beetles in the subfamily Eumolpinae. It was first described by the Czech entomologist Jan Bechyné in 1950. There are three described species in Chrysodinopsis. The genus is possibly synonymous with Brachypnoea.
Cryptocephalus sanguinicollis is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
Diachus is a genus of case-bearing leaf beetles in the family Chrysomelidae. There are about 10 described species in Diachus.
