Gelonus is a genus of leaf-footed bugs (Coreidae) in Tasmania, one of the few Coreidae that feeds on eucalypts. It is a member of the tribe Amorbini, but has only a single species, Gelonus tasmanicus .[1]
Although this Tasmanian leaf-footed bug was first described in 1841 by Élie Jean François Le Guillou as Syromastes tasmanicus,[2] it wasn't until 1873 that Carl Stål placed it in his newly formed genus Gelonus, as Gelonus tasmanicus.[3] Stål created the genus Gelonus in 1865 in volume two of his three volume Hemiptera Africana.[4] The following year he categorized the type species of the genus as Gelonus discolor,[5] the bug described by William Dallas in 1852 as Amorbus discolor.[6] In 1873, Stål established the synonymity of the two species, with Gelonus discolor being the junior synonym, and le Guillon's Gelonus tasmanicus the senior.
