Diagnosis

This species can be distinguished from all its congeners by the combination of the following characters: face black, at most about as broad as high ( Fig. 1A View Fig. 1 ); pleural carina defined; metasoma with T1 relatively short (1.9 × as long as broad posteriorly) ( Fig. 1B View Fig. 1 ); hind leg with coxa, at least partly, yellowish ( Fig. 1C View Fig. 1 ).

Etymology

The species name refers to the type locality (Volcán Atitlán).
