Pérez-Gutierrez & Palacino-Rodríguez (2011) reported H. breweri from Colombia, in Meta Department. We report this species for the first time from Guainía and Vaupés Departments. Males of this species have a distinctive yellow coloration on the thorax, small size (abdomen <34mm) and robust cerci ( Figs. 8 D–F), indeed the widest of the Colombian species in lateral view. Female is very similar to H. bariai , their differences are detailed above.
