Atta sexdens (Linnaeus)
Commensal.—Attaphila sexdentis, Brazil, San Leopoldo (Bolívar, 1905): Found in nests of the ant.
Atta texana (Buckley)
Synonymy.—Atta fervens Say [Wheeler, 1910].
Commensal.—Attaphila fungicola, U.S.A., Texas (Wheeler, 1900, 1910): The cockroach does not feed on the fungus in the ants' nest, as Wheeler (1900) first supposed, but mounts the back of the soldiers and licks their surfaces. It is tolerated by the ants with no signs of hostility. The antennae of the cockroach are clipped short. Although Wheeler (1910) stated that this is probably accidental or unintentional, it is peculiar that Bolívar (1905) noticed the same invariable mutilation of the antennae of Attaphila bergi. Wheeler (1900) had originally suggested that the antennae were probably clipped off by the ants which are continuously trimming the fungus hyphae. Louisiana (Moser, personal communication, 1959): Numerous specimens were encountered in some nests of A. texana. This cockroach is the most closely associated inquiline in the nest and maintains very intimate terms with the ants. It is found living in the fungus cavities and tunnels.
Crematogaster limata parabiotica Forel
Commensal.—Phorticolea boliviae, Bolivia, Cachuela Esperanza (Caudell, 1923): Collected in joint nests of C. limata and Componotus femoratus.
Solenopsis geminata (Fabricius)
Commensal.—Myrmecoblatta wheeleri, Guatemala (Hebard, 1917a): Collected from a colony of this ant under a stone on the shores of Lake Atitlan, altitude 11,719 feet.
