Megalostomis Chevrolat 1836: 416

provided by EOL authors

Megalostomis Chevrolat 1836: 416; Lacordaire 1848: 519; Blanchard 1851: 534; Chapuis 1874: 135; Gemminger & Harold 1874: 3294; Jacoby 1876: 809, 1880: 29; Horn 1892: 10; Jacoby & Clavareau 1906: 58; Clavareau 1913: 74; Bruch 1914: 348; Guérin 1943: 9; Monrós 1953a: 61, 1953b: 46; Moldenke 1970: 14, 1981: 99.

Species number. 43 spp (Agrain 2013, 2014)

Type species. Clythraboopis Germar 1824 [= Megalostomis grossa (Forsberg 1821), by subsequent designation (Monrós 1953b: 46].

Distribution. Nearctic, Neotropical, Panamanian

Notes. This genus was revised by Agrain (2013). Megalostomis currently includes 43 species (Agrain 2014). According to Agrain & Roig-Juñent (2011) this genus is supported by two synapomorphies: eyes strongly emarginated, and dorsal plate of aedeagus with straight margin. The morphology in the genus is highly variable, especially for sexual dimorphic features in males such as: a greater development of mandibles, the presence of constrictions in the pronotal disc, development of double infraocular projection and lengthening of forelegs (Agrain 2013).
