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 Cassidinae are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.
Xanthonia is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in North and Central America, and in East, Southeast and South Asia.
Omocerus bicornis is a species of tortoise beetle from South America. It lives on Cordia (Boraginaceae) plants, and is found in Brazil, Suriname, French Guiana, Suriname and Venezuela. It was first described by Carl Linnaeus in his 1763 work Centuria Insectorum under the name Cassida bicornis, and was later made the type species of the genus Omocerus by Philogène Auguste Joseph Duponchel and Alcide d'Orbigny in 1843.
The Spilopyrinae are a small subfamily of the leaf beetles, or Chrysomelidae. They occur in 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.
Chalepini is a tribe of leaf beetles in the family Chrysomelidae. There are at least 50 genera and 830 described species in Chalepini.
Stenispa is a genus of tortoise beetles and hispines in the family Chrysomelidae. There are at least 20 described species in Stenispa.
Brachycoryna is a genus of tortoise beetles and hispines in the family Chrysomelidae. There are seven described species in Brachycoryna.
Anisostena is a genus of tortoise beetles and hispines in the family Chrysomelidae. There are at least 30 described species in Anisostena.
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.
Erepsocassis is a genus of tortoise beetles in the family Chrysomelidae, containing a single species, E. rubella.
Charidotella is a genus of tortoise beetles in the family Chrysomelidae. There are at least 100 described species in Charidotella.
Metaparia is a genus of leaf beetles in the subfamily Eumolpinae. There are nine described species in Metaparia, distributed from the United States to Central America.
Hilarocassis is a genus of tortoise beetles and hispines in the family Chrysomelidae. There are about 10 described species in Hilarocassis.
Hemisphaerota is a genus in the subfamily Cassidinae in the family Chrysomelidae. There are about 10 described species in Hemisphaerota.
Octotoma is a genus of tortoise beetles and hispines in the family Chrysomelidae. There are about 12 described species in Octotoma.
Lobispa is a genus of leaf beetles consisting of three species from Central America and northern South America. It is classified within the tribe Cubispini, which is placed within the subfamily Eumolpinae. The genus superficially resembles the subfamily Hispinae.
Tricliona is a genus of leaf beetles in the subfamily Eumolpinae. It contains at least 35 species, and is distributed from India and Southern China to the Philippines and New Guinea.
Cubispini is a tribe of leaf beetles from the Neotropical realm. It is classified within either the Eumolpinae or the Cassidinae. It was established by Francisco Monrós in 1954 to contain the genus Cubispa, which was originally placed in the subfamily Hispinae, in the tribe Cephaloleini. A second genus, Lobispa, was described and placed in the tribe by C.L. Staines in 2001.
The Neotropical tortoise beetle tribe Spilophorini comprises two genera, Calyptocephala Chevrolat, 1836 and Spilophora Boheman, 1850. Biological information is limited but the life cycle includes six larval instars and the larvae construct a shield of their cast skins.
