Taxonomic revision of Megalothoraca (Diptera: Richardiidae) with description of a new species, synonyms and new combination

Wendt, Lisiane DilliMarinoni, Luciane

A taxonomic revision of Megalothoracha Hendel, 1911 is provided, including a description of Megalothoraca rosalyae Wendt, sp. nov. from Colombia. The genus encompasses large species from Colombia, Ecuador, Peru and Bolivia (new record), and each species was described based either on males or females. These species can be diagnosed by long and slender mid and hind legs and wing longer than body, vein R2+3 with two strong curves on apical third, and short spurious vein medially. And males have costal vein conspicuously bowed anteriorly and thickened on medial portion. The following nomenclatural changes are made: Megalothoraca hendeli Enderlein, 1912, syn. nov. is a junior synonym of M. pterodontida Hendel, 1911; Batrachophthalmum teleopsis (Hennig, 1938) comb. nov. is transferred from Megalothoraca, and Batrachophthalmum quimbaya Carvalho, Wolff & Wendt, 2011, syn. nov. is a junior synonym of B. teleopsis. A key to species and illustrations of the female and male terminalia are provided.(AU)
