Rediscovery of the morphologically remarkable social parasite Pheidole acutidens (Bruch), with the first records for Brazil.

Alexandre Ferreira, Mila Martins, Rodrigo Feitosa


Pheidole acutidens is a social parasite of the congeneric species P. nitidula. Since its description, the species was considered native to Argentina. In this paper we report the first records of P. acutidens for Brazil from the southern states of Santa Catarina and Rio Grande do Sul). These records extend the known distribution of the species at least 1,000 km to the north. We suggest that the scarce representation of this species in entomological collections is due to its peculiar reproductive strategy, which renders the species inconspicuous and limits its dispersion
