Eumolpinae

Eumolpinae can be recognized at first sight by their rounded thoraces, more or less spherical or bell-shaped, but always significantly narrower than the mesothorax as covered by the elytra. Additional features include a small head set deeply into the thorax, and usually well-developed legs.

They generally resemble other Chrysomelidae, but differ in having front coxae rounded and third tarsal segment bilobed beneath. Many are metallic, or yellow and spotted. The dogbane beetle (Chrysochus auratus), for instance, is very attractive—iridescent blue-green with a coppery tinge, it measures 8–10 mm, and is found on dogbane and milkweed. Some, such as members of the genus Macrocoma, are unusually setaceous and with unusually prominent mandibles for members of the family Chrysomelidae.

The Eumolpinae are distributed worldwide. They are numerous in the tropics and subtropics, particularly in South America, tropical Africa, Australia, New Guinea, Fiji and New Caledonia, but are progressively less common towards the north.[2] They have a high species richness in New Caledonia.[3]

The number of tribes in the subfamily varies depending on the author. According to a classification from 2011, for instance, there are 12 tribes:[4]

• Bromiini Baly, 1865 (1863) – also known as "Adoxini" in some classifications; some authors split this into additional tribes such as "Myochroini" and "Scelodontini".
• Caryonodini Bechyné, 1951 – contains only Caryonoda.
• Cubispini Monrós, 1954 – contains only Cubispa and Lobispa; some authors exclude this tribe from Eumolpinae and retain it within Cassidinae instead.
• Eumolpini Hope, 1840 – also known as "Colaspoidini" in some classifications; some authors split this into additional tribes such as "Iphimeini" and "Endocephalini".
• Euryopini Chapuis, 1874 – also known as "Colasposomini" in some classifications.
• Habrophorini Bechyné & Špringlová de Bechyné, 1969 – contains only Habrophora and Psathyrocerus.
• Hemydacnini Bechyné, 1951 – contains only Hemydacne and Colasita.
• Megascelidini Chapuis, 1874 – contains only Megascelis and Mariamela; formerly considered a separate subfamily.
• Merodini Chapuis, 1874 – contains only Meroda.
• Pygomolpini Bechyné, 1949 – contains only Pygomolpus.
• Rosiroiini Bechyné, 1950 – contains only Rosiroia.
• Typophorini Baly, 1865 – also known as "Nodinini" in some classifications; some authors split this into additional tribes such as "Metachromini".

The tribe Eupalini was proposed in 2005 for the genus Eupales (also known as Floricola).[5] However, the name "Eupalini" was not explicitly indicated as new, so it is currently considered an unavailable name according to the ICZN.

The subfamily Spilopyrinae was formerly considered a tribe of Eumolpinae, while recently the subfamily Synetinae has sometimes been grouped within Eumolpinae.
