A new species of Stilobezzia (Diptera: Ceratopogonidae) from northern Argentina

Abstract

A new Neotropical species, Stilobezzia (Stilobezzia) biscutata sp. nov. (Diptera: Ceratopogonidae), is described and illustrated based on adult specimens collected in the Argentinian provinces of Chaco, Formosa and Corrientes. The species is compared with Stilobezzia transversa Lane & Forattini, 1958, from which it differs mainly in the pigmentation pattern of abdomen and the parameres S-shaped.
