Megacyllene Casey, 1912

Newman (1840) described the new genus Cyllene for Cyllene spinifera Newman, 1840 (now Megacyllene nebulosa Laporte and Gory, 1836) (Monné 2018). Subsequently, Casey (1912) described Megacyllene for Clytus antennatus White, 1855 . Hopping (1932) disagreed with the Casey concept and placed Megacyllene into synonymy with Cyllene . Fisher (1945) found Cyllene Newman, 1840 to be preoccupied by Cyllene Gray, 1834 (Mollusca) and designated Megacyllene as a replacement. The genus is restricted to America (New World) (most species are neotropical) and is currently composed of 54 species and two subspecies (Bezark 2019; Tavakilian and Chevillotte 2018). Recently, the South American species were revised by Martins and Galileo (2011). A new species from west-central Mexico (Nayarit) is described below.
