Brachymyrmex aphidicola Forel 1909  . NEW STATUS.

Brachymyrmex heeri  var. aphidicola Forel 1909: 263  . [w syntypes examined, MHNG; San Bernadino, Cordillera, Paraguay (Fiebrig)].

Brachymyrmex heeri  var. fallax Santschi 1923 a: 665  . NEW SYNONYMY. [Holotype examined, NHMB; Paraguay (s. loc.)].

There is little reason to consider Brachymyrmex heeri  and B. aphidicola  as conspecific, as both species are locally sympatric and morphologically distinct in eastern Paraguay. Brachymyrmex aphidicola  is one of the most abundant ground and litter nesting ant species in Paraguayan forests. Brachymyrmex heeri  is more rarely collected, the two nest records I have from Paraguay are both arboreal. The two species are easily separated by the pubescence on gastric tergite 1 (= abd. tergite 3), with the pubescence dense on B. heeri  and sparse on B. aphidicola  . Santschi’s type of B. heeri fallax  ( NHMB, examined) falls within the range of variation exhibited by B. aphidicola  in Paraguay and is synonymized here. It is worth mentioning here that Paraguayan specimens of B. heeri  are a close match, in both the worker and queen castes, to Forel’s types of B. heeri  ( MHNG, examined) described from an introduced population in Switzerland (Forel 1874).

Given the notoriously poor taxonomic state of Brachymyrmex  and the ubiquity of B. aphidicola  in the region, there may well exist an older name for this species. A thorough taxonomic revision of this genus is sorely needed.
