Worker head shape in Myrmelachista nodigera HNS 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 HNS and pallida HNS , both from Paraguay. Mayr’s M. nodigera HNS type is a larger and more robust worker than the types of M. flavicornis HNS and M. pallida HNS , 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 HNS on color is baseless. In my estimation the known Paraguayan collections related to M. nodigera HNS comprise a single species.
Forel’s type of Myrmelachista arborea HNS (MHNG examined) from San Bernadino is a single queen unassociated with workers. Judging from the shape of the petiole, M. arborea HNS may be the queen of M. nodigera HNS . Further collections to obtain complete nest series will help establish the identity of this species.
