Jean-Pierre Lacroix (1938–1989) was a French entomologist.
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.
Zenocolaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North America and South America. There are at least two described species in Zenocolaspis. The genus is very similar to Colaspis, but the body is smaller and the eyes are strongly convex and prominent externally.
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.
Prionodera is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Central and South America.
Metaxyonycha is a genus of leaf beetles in the subfamily Eumolpinae.
Alethaxius is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed from Mexico to northern South America, and it is also found in the West Indies. The genus was originally named Aletes by Félicien Chapuis in 1874. However, this name was preoccupied by Aletes Carpenter, 1857, so the genus was renamed to Alethaxius by Édouard Lefèvre in 1885. According to Flowers (1996), it is very likely that Alethaxius is polyphyletic and represents at least three different genera.
Allocolaspis is a genus of leaf beetles in the subfamily Eumolpinae.
Percolaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in South America and Central America, though it has also been reported from southern Florida in the United States. It is associated with the plant families Rubiaceae and Fabaceae in Central America.
Callicolaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is known from South America. It was formerly considered a synonym of Lycaste Gistel, 1848, but in 2003 it was restored as a separate genus. Lycaste itself was later found to be an unnecessary replacement name for Chalcophana, and the name Eupetale was established for the species formerly placed under Lycaste.
Antitypona is a genus of leaf beetles in the subfamily Eumolpinae. They are found in Central America and South America.
Chalcophana is a genus of leaf beetles in the subfamily Eumolpinae.
Typophorus nigritus is a species of leaf beetle in the subfamily Eumolpinae. It is found in North, Central, and South America.
Chalcoplacis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in South America.
Anachalcoplacis is a genus of leaf beetles in the subfamily Eumolpinae. It is known from South America.
