Jansonius is a genus of leaf beetles in the subfamily Eumolpinae. It is found in Chile [3] and Argentina. [4] It was formerly placed in the tribe Adoxini, section Myochroites, but is now placed in Nodinini, section Metachromites. [2]
The genus contains at least one valid species:
Dia patagonicaBoheman, 1858, also from Chile, was placed in the genus by Jan Bechyné in 1953, but as the type is apparently lost or destroyed, this species is considered incertae sedis in Eumolpinae by Askevold & LeSage (1990). [2]
Several additional species were described in or assigned to the genus by Jan Bechyné from other countries in South America, though these may not belong to the genus according to Askevold & LeSage (1990): [2]
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.
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.
Brachypnoea is a genus of leaf beetles in the subfamily Eumolpinae. It is mostly found in the Neotropical realm, though there are also eight known species in the Nearctic realm.
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.
Rhabdopterus is a genus of leaf beetles in the subfamily Eumolpinae. There are about 70 described species in Rhabdopterus from North and South America, eight of which are found north of Mexico. The Nearctic species may not be congeneric with the type species, which is South American.
Spintherophyta is a genus of leaf beetles in the subfamily Eumolpinae. Most species in the genus are found in Central and South America, but there are also a few North American species.
Typophorus is a genus of leaf beetles in the subfamily Eumolpinae. There are at least 53 described species in Typophorus. Similar genera include Paria and Tijucana. Typophorus itself is probably polyphyletic.
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.
Metaxyonycha is a genus of leaf beetles in the subfamily Eumolpinae.
