The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research.
The Cryptocephalinae are a subfamily of the leaf beetles (Chrysomelidae), and belong to the group of case-bearing leaf beetles called the Camptosomata. The cases are made from the feces of larvae, passed from one instar to the next, and ultimately serves as a pupation chamber.
The Eumolpinae are a subfamily of the leaf beetles, or Chrysomelidae. It is one of the largest subfamilies of leaf beetles, including more than 500 genera and 7000 species. They are oval, and convex in form, and measure up to 10 mm in size. Typical coloration for this subfamily of beetles ranges from bright yellow to dark red. Many species are iridescent or brilliantly metallic blue or green in appearance.
The Cryptocephalini are a tribe within the leaf beetle subfamily Cryptocephalinae. As the other Cryptocephalinae, they belong to the group of case-bearing leaf beetles known as Camptosomata. Some species are myrmecophilous.
The Spilopyrinae are a small subfamily of the leaf beetles, or Chrysomelidae. They occur in Argentina, Australia, New Guinea, New Caledonia and Chile. They were formerly considered a tribe of the subfamily Eumolpinae. The group was elevated to subfamily rank by C. A. M. Reid in 2000. However, some authors have criticised this placement, preferring to retain them within the Eumolpinae.
Griburius is a genus of case-bearing leaf beetles in the family Chrysomelidae. There are many species, with about six described species that occur in the USA.
Sumitrosis is a genus of leaf beetles in the family Chrysomelidae. There are at least 60 described species in Sumitrosis.
Chalepini is a tribe of leaf beetles in the family Chrysomelidae. There are at least 50 genera and 830 described species in Chalepini.
Neolema is a genus of leaf beetles in the family Chrysomelidae. Eight described species currently are placed in Neolema.
Bassareus is a genus of case-bearing leaf beetles in the family Chrysomelidae. There are about eight described species in Bassareus.
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.
Phyllotreta undulata, known generally as the small striped flea beetle or turnip flea beetle, is a species of flea beetle in the family Chrysomelidae. It is found in Australia, Europe and Northern Asia, North America, and Oceania.
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.
Luperini is a tribe of skeletonizing leaf beetles in the family Chrysomelidae. There are more than 30 genera and 500 described species in Luperini.
Cryptocephalus sanguinicollis is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
Typophorini is a tribe of leaf beetles in the subfamily Eumolpinae. The tribe contains approximately 100 genera, which are found worldwide. Members of the tribe are mainly characterized by notches on the tibiae of the middle and hind legs, which are sometimes referred to as antenna cleaners. They also generally have a subglabrous body, as well as bifid pretarsal claws.
Euryopini is a tribe of leaf beetles in the subfamily Eumolpinae.
Bromiini is a tribe of leaf beetles in the subfamily Eumolpinae. The tribe contains approximately 120 genera, which are found worldwide. They are generally thought to be an artificial group, often with a subcylindrical prothorax without lateral ridges and covered with setae or scales.
Metallactus is a genus of case-bearing leaf beetles in the family Chrysomelidae. There are over 70 described species distributed across South America.
Mylassa is a genus of case-bearing leaf beetles in the family Chrysomelidae. It is the only member of the tribe Mylassini within the subfamily Cryptocephalinae. There are seven or eight described species distributed in the southern part of South America.
