Two new species of Buenoa Kirkaldy, 1904 (Hemiptera: Heteroptera: Notonectidae) from the States of Amazonas and Roraima, Brazil

Abstract

The genus Buenoa has 63 described species, and there are 13 species in the Northern region of Brazil. In this study we describe two new species: B. dilaticrus sp. nov. (Alto Alegre - State of Roraima and Barcelos - State of Amazonas), similar to B. tibialis Truxal, 1957, but distinguished mainly by the lateral expansion near the base of the lateral margin of the mid-tibia; and B. exilidens sp. nov. (Barcelos - AM), similar to B. platycnemis (Fieber, 1851), B. mutabilis Truxal, 1953, and B. tumaquensis Padilla-Gil, 2010, distinguished by the rostral prong, chaetotaxy, and stridulatory area of fore femur and the number of stridulatory teeth on the fore tibia.
