Comments. I was not able to see the holotype of G. chiliensis , deposited in the FSC, but I could study paratypes from the Museo Nacional de Historia Natural (MNNC). The types of G. nigritulus and G. chiliensis are similar in external characters and identical in the shape of the aedeagus. These names are considered to be synonyms.
