Chrysochus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North America, Europe and Asia.


The name of the genus is derived from the Greek χρυσοχόος (chrysochóos), meaning "goldsmith".[2]
Taxonomic history

In 1836, the genus Chrysochus was first established by Louis Alexandre Auguste Chevrolat in Dejean's Catalogue des Coléoptères, including the species Chrysomela asiatica Pallas, 1771, C. aurata Fabricius, 1775 and C. pretiosa Fabricius, 1792 (now Chrysochares asiaticus, Chrysochus auratus and Chrysochus asclepiadeus, respectively). Chrysomela praetiosa was designated as the type species of the genus by Sylvain Auguste de Marseul in 1864.[3]

The generic name Chrysochus Chevrolat in Dejean, 1836 is a conserved name. It was threatened by Eumolpus in the sense used by Kugelann in Illiger, 1798, which included Chrysomela praetiosa. An application to conserve Chrysochus and other names by suppressing Eumolpus Illiger, 1798 was accepted by the International Commission on Zoological Nomenclature in 2012.[4][5]

There are at least eight described species in Chrysochus. Six are found in the Palearctic realm,[6] and only two are found in North America.

Chrysochus asclepiadeus (Pallas, 1773) – widespread across Europe, also found in Kazakhstan and Turkey
Chrysochus asclepiadeus asiaeminoris De Monte, 1948 (Considered a synonym by Ekiz et al. (2015)[7])
Chrysochus auratus (Fabricius, 1775) – Dogbane beetle; found in eastern North America
Chrysochus brevefasciatus Pic, 1934[8] – found in Shanghai, China
Chrysochus chinensis Baly, 1859[9] – found in Central, North and Northeast China, Japan, Mongolia and the Russian Far East
Chrysochus cobaltinus LeConte, 1857 – Blue milkweed beetle; found in the western United States and British Columbia
Chrysochus globicollis Lefèvre, 1888 – found in Northeast China, the Russian Far East and North Korea
Chrysochus goniostoma Weise, 1889 – found in North and Northeast China, Mongolia, and the Russian Far East
Chrysochus sikhima Jacoby, 1908[10] – found in Sikkim, India

Another species, Chrysochus mniszechi, was described in 1877 by Édouard Lefèvre, from three specimens he had seen (one in the collection of Georges Mniszech [fr], and two from Henry Deyrolle's). While he did not know where the specimens were collected from, Lefèvre thought that they probably came from North America.[11]

The following species, all from the Oriental realm, were formerly included in Chrysochus. They were transferred to the genera Parheminodes and Platycorynus in 2021:[12]

Chrysochus conspectus Lefèvre, 1890: moved to Parheminodes
Chrysochus hageni Jacoby, 1884:[13] moved to Parheminodes
Chrysochus languei Lefèvre, 1893: moved to Platycorynus
Chrysochus massiei Lefèvre, 1893: moved to Parheminodes
Chrysochus mouhoti Baly, 1864: moved to Parheminodes
Chrysochus nilgiriensis Jacoby, 1908:[10] moved to Parheminodes
Chrysochus pulcher Baly, 1864:[14] moved to Parheminodes


All species of Chryochus feed on plants in the Apocynaceae (dogbane) and Asclepiadaceae (milkweed) families. A small mutation has allowed the two North American species, C. auratus and C. cobaltinus, in particular to feed on the plant species containing cardenolides, while all other species of the genus feed on plant species without cardenolides.[15]
