Euryptera Lepeletier & Audinet-Serville, 1828

Euryptera Lepeletier & Audinet-Serville in Latreille, 1828: 687 ; Monné, 2006:121 (cat.). Type species: Euryptera latipennis Lepeletier & Audinet-Serville, 1828 (monotypy).

Lepeletier & Audinet–Serville (1828) proposed Euryptera for E. latipennis from Brazil. The genus was distinguished from the other Lepturinae by the 12-segmented antennae. This character was not found in any specimens we examined, and it is possible that the appendiculate eleventh antennomere led the authors to an erroneous observation.

Presently, Euryptera is distinguished from the other South American genera by the broad intercoxal process of the mesosternum, which is at least 2/3 the diameter of the coxal cavity; the expanded elytral apices; and by the elytral carinae. There are ten species in the Neotropical region ( Monné 2006) and only E. albosterna Chemsak & Linsley, 1974 occurs in Central America . Three species are herein transferred from Euryptera to Megachoriolaus : Megachoriolaus atripennis ( Bates, 1870) new combination, Megachoriolaus bicolor ( Gounelle, 1911) new combination, and Megachoriolaus venusta ( Breme, 1844) new combination. Euryptera brasiliensis Fuchs, 1956 and E. virgata Gounelle, 1911 are considered synonyms of E. latipennis Lepeletier & Audinet-Serville, 1828 . Only four species remain in Euryptera : E. latipennis , E. leonina Gounelle, 1911 , E. unilineatocollis Fuchs, 1956 and E. nigrosuturalis Melzer, 1935 . This last species remains in the genus because, at the moment, it is impossible to locate it in the correct genus.
