Platycorynus is a genus of leaf beetles in the subfamily Eumolpinae. Species of the genus are found in Africa and Asia.
The generic name "Platycorynus" first appeared in the second and third editions of Dejean's Catalogue of Coleoptera, where it was attributed to Chevrolat. Nine species were listed for the genus, four of which were nomina nuda at the time of publication, but no formal description was given for it. The genus was later briefly characterized by Frederick William Hope in 1840, under the new name "Corynodes". In 1865, Thomas Ansell Marshall published a monograph on Corynodes, dividing it into seven subgenera: Platycorynus, Corynodes, Theumorus, Eurycorynus, Omodon, Erigenes, and Bathycolpus. The latter five were originally intended to be new genera. [3] In the same year, Hamlet Clark created a new genus, Corynoeides, for one of the species placed in Corynodes. [4] However, Joseph Sugar Baly did not accept Clark's genus nor Marshall's subdivisions. [6] In 1956, Monrós & Bechyné pointed out that Platycorynus Chevrolat in Dejean, 1836 was available and had priority over Corynodes Hope, 1840, and that therefore the former should be used as the valid name for the genus. [7]
According to Volume 6 of the Catalogue of Palearctic Coleoptera, published in 2010, Corynodes, Corynoeides, Eudora, Neolycaria and all of Marshall's subgenera are now treated as synonyms of Platycorynus. [2]
The genus includes the following species: [8] [9] [10] [11] [12]

Species moved to other genera:
Colasposoma is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa, Asia and Australia.
Colaspoides is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 260 species worldwide. It is an extant genus but there is at least one species, C. eocenicus, found in Baltic amber from the Upper Eocene of Russia, and the genus has also been reported from the Miocene of the Dominican Republic.
Demotina is a genus of leaf beetles in the subfamily Eumolpinae. There are over 50 described species in Demotina. The genus is native to Asia, Australia and Oceania, though one species is an adventive species in the southeastern United States in North America. Some species are known to be parthenogenetic.
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.
Hyperaxis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in East and Southeast Asia.
Rhyparida is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in the Australasian and Indomalayan realms, though some species are also known from the African islands of Madagascar and Seychelles.
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.
Abirus is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed from the Malay Archipelago to the Indian subcontinent, China, and the Ryukyu Islands. The genus was first established by the Belgian entomologist Félicien Chapuis in 1874, as a split of Dermorhytis.
Pagria is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa, Asia and Australia.
Basilepta is a genus of leaf beetles in the subfamily Eumolpinae. It is generally distributed in Asia. A single species is also known from central Africa.
