El género neotropical Brachymyrmex Mayr (Hymenoptera: Formicidae) en la Argentina. III: redescripción de las especies: B. aphidicola Forel, de B. australis Forel y B. constrictus Santschi

Abstract

-Three species of the genus Brachymyrmex: B. aphidicola Forel, (n.stat.); B. australis Forel y B. constrictus Santschi are redescribed hereafter. Descriptions and drawings of main morphological characters of gynes, males and workers are given. New characters are used to differentiate species, mainly based on male head morphology and genitalia. New Argentine localities are added to the known distribution.

Molecular and morphological recognition of species boundaries in the neglected ant genus Brachymyrmex (Hymenoptera: Formicidae): toward a taxonomic revision

“…Since , Alayo (1974) examined the species from Cuba and Wheeler and Wheeler (1978) those from the United States. More recently, Quirán and collaborators (Quirán et al 2004;Quirán 2005Quirán , 2007 reported on the Brachymyrmex species from Argentina, and Ortiz and Fernández (2014) reviewed the species with tumuliform metathoracic spiracles. Additionally, Wilson et al (2016) documented the male genitalia of Brachymyrmex.…”

Morphology of the male genitalia of Brachymyrmex and their implications in the Formicinae phylogeny

“…Though this is a tentative evaluation that requires further sampling to fully elucidate. Quirán's (2007) illustration of Brachymyrmex australis Forel, 1901 is difficult to place in either conformation group. The penisvalvae illustration lacks a raised anterior portion, however the lateral carina is not indicated, furthermore the volsella is similar to those in conformation 2, with a medial concavity (see discussion of the volsella below).…”
