Worker head shape in Myrmelachista nodigera  shows slight allometric variation within nest series, with larger workers having somewhat broader heads, and this variation may have misled Emery and Forel in defining their intraspecific taxa flavicornis  and pallida  , both from Paraguay. Mayr’s M. nodigera  type is a larger and more robust worker than the types of M. flavicornis  and M. pallida  , yet single nest series I have collected in Canindeyú and San Pedro span the range of variation encompassed by the type specimens for all three taxa. Color is also variable within a nest, presumably related to worker age, so Forel’s distinction of M. pallida  on color is baseless. In my estimation the known Paraguayan collections related to M. nodigera  comprise a single species.

Forel’s type of Myrmelachista arborea  ( MHNG, examined) from San Bernadino is a single queen unassociated with workers. Judging from the shape of the petiole, M. arborea  may be the queen of M. nodigera  . Further collections to obtain complete nest series will help establish the identity of this species.
