description Of the 30 Neotropical species of Brachymyrmex, 26 live in Argentina. This genus was originally proposed by G. Mayr to for the Argentinian B. patagonicus. Santschi published the only systematic revision presently available, but several species cannot be yet easily separated or named. In this paper we redescribe B. patagonicus - the type species of Brachymyrmex - as well as B. bruchi and B. oculatus. Descriptions and drawings of the main morphological characters of queens, males and workers are given. Analyzed specimens belong to theCollections in the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Museo de La Plata, Argentina and the Naturhistorisches Museum Wien. New characters are used to differentiate species, mainly male head morphology and genitalia. Two new synonymies are proposed: B. patagonicus var. atratulus = B. patagonicus and B. bruchi var. rufipes = B. bruchi, as we do not consider that differences in worker body color justify subspecific separation. Lectotype is designated for B. oculatus.

Brachymyrmex systematics taxonomy diagnosis Brachymyrmex sistemática taxonomía diagnosis Of the 30 Neotropical species of Brachymyrmex, 26 live in Argentina. This genus was originally proposed by G.

Lectotype is designated for B. oculatus. El género Brachymyrmex es originario de la Región Neotropical donde incluye aproximadamente 30 especies, de las cuales 26 se han citado para la Argentina. Fue establecido para B. patagonicus (Mayr 1868). Santschi (1923) hizo la única revisión sistemática completa del género existente hasta la fecha, pero restan ambigüedades en la identificación de algunas especies. En este trabajo se redescriben la especie tipo del género, B. patagonicus, como asimismo B. bruchi y B. oculatus. Se acompañan las descripciones de las diferentes castas (obrera, reina y macho) con ilustraciones de los principales caracteres morfológicos utilizados en la identificación. Se designa lectotipo para B. oculatus. El material estudiado pertenece al Museo Argentino de Ciencias Naturales “B. Rivadavia”, al Naturhistorisches Museum Wien, y al Museo de La Plata.
