Disonycha is a genus of flea beetles in the family Chrysomelidae, containing some 170 species in the Nearctic and Neotropics. [1]
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily.
Altica is a large genus of flea beetles in the subfamily Galerucinae, with about 300 species, distributed nearly worldwide. The genus is best represented in the Neotropical realm, well represented in the Nearctic and Palearctic, but occurs also in the Afrotropic, Indomalaya, and Australasia. The species are similar to each other, small metallic blue-green-bronze beetles, often distinguished from each other only by the aedeagus. The species of Altica, both as larvae and as adults, are phytophagous, feeding on plant foliage of various food plant taxa, specific for each Altica species. Onagraceae and Rosaceae are the dominant host plant families for Holarctic species. The adult Altica beetles are able to jump away when approached.
Chaetocnema is a genus of flea beetles in the family Chrysomelidae. There are some 470 described species worldwide.
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.
Psylliodes is a large genus of flea beetles in the family Chrysomelidae. There are about 200 described species worldwide.
Brachiacantha is a genus of lady beetles in the family Coccinellidae. There are at least 25 described species in Brachiacantha.
Phyllobrotica is a genus of skeletonizing leaf beetles and flea beetles in the family Chrysomelidae. There are at least 18 described species in Phyllobrotica.
Saxinis is a genus of case-bearing leaf beetles in the family Chrysomelidae. There are at least 10 described species in Saxinis.
Paria is a genus of leaf beetles in the subfamily Eumolpinae. There are about 40 described species in Paria in North and South America, 19 of which are known north of Mexico. The genus is very similar to Typophorus.
Bitoma is a genus of cylindrical bark beetles in the family Zopheridae. There are about 15 described species in Bitoma.
Myochrous is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North, Central and South America. There are over 50 described species in Myochrous. The generic name is a combination of the Ancient Greek words μῦς (mouse) and χρῶμα (color).
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.
Glyptina is a genus of flea beetles in the family Chrysomelidae. There are about 15 described species in Glyptina.
Kuschelina is a genus of flea beetles in the family Chrysomelidae. There are some 30 described species, from the Nearctic and Neotropics.
Systena is a genus of flea beetles in the family Chrysomelidae. There are about 90 described species, found in the New World, mostly in the Neotropics.
Mycetochara is a genus of comb-clawed beetles in the family Tenebrionidae. There are at least 30 described species in Mycetochara.
Trirhabda is a genus of skeletonizing leaf beetles in the family Chrysomelidae. There are more than 30 described species in Trirhabda. They are found in North America and Mexico.
Capraita is a genus of flea beetles in the family Chrysomelidae. There are some 60 described species in the Nearctic and Neotropics.
