Abstract: The fungus-growing ants (Tribe Attini) are a New World group of > 200 species, all obligate symbionts with a fungus they use for food. Four attine taxa are known to be social parasites of other attines. Acromyrmex (Pseudoatta) argentina argentina and Acromyrmex (Pseudoatta) argentina platensis (parasites of Acromyrmex lundi), and Acromyrmex sp. (a parasite of Acromyrmex rugosus) produce no worker caste. In contrast, the recently discovered Acromyrmex insinuator (a parasite of Acromyrmex echinatior) does produc… Show more

“…Testing for the presence of social parasite workers Some morphologically highly derived socially parasitic fungus-growing ant species lack a worker caste entirely whereas other social parasites that are morphologically similar to their hosts are known to produce between 9 and 48 % of the workers in infected host colonies (Sumner et al 2003a;De Souza et al 2007). The morphological differences between parasite and host workers can be subtle.…”

“…Pseudoatta argentina and the distantly related new species from Bahia have converged on the anatomical parasitic syndrome, or inquiline syndrome, which is characterized by a reduction of body size, mouthparts, and integumental sculpturing, as well as by a loss of the worker caste (Kutter 1969;Wilson 1971Wilson , 1984Hölldobler and Wilson 1990). In contrast, A. insinuator strongly resembles its host species, and A. ameliae differs from all other parasites in that it still resembles the host while at the same time having experienced a marked reduction in size and an increased abundance of pilosity (Schultz et al 1998;De Souza et al 2007). Both A. insinuator and A. ameliae retain the ability to produce minor and medium-size workers (Sumner et al 2003a;De Souza et al 2007).…”

“…Acromyrmex ameliae has recently been described by De Souza et al (2007). It is a social parasite of the inquiline type that has a few minor workers similar to those of its hosts, the leaf-cutting ants Acromyrmex subterraneus subterraneus Forel and Acromyrmex subterraneus brunneus (Forel), and appears to be closely related to these hosts.…”
