Unknown host
Cockroach.—Attaphila flava, British Honduras (Gurney, 1937): Because the known hosts of the other five species of Attaphila are ants, we presume that this species also lives in the nest of some myrmecine ant.
Subfamily PONERINAE
Odontomachus affinis (Guérin)
Commensal.—Myrmeblattina longipes, Brazil, Rio de Janeiro (Chopard, 1924, 1924a; Hancock, 1926): Originally described as Phileciton longipes by Chopard (1924) from the nest of an ant mistakenly identified as Eciton sp.
Family VESPIDAE
Polybia pygmaea Fabricius
Commensal.—Sphecophila polybiarum, French Guiana (Shelford, 1906a): Shelford stated that it was probable that the cockroaches living on the floor of the paper nest fed on small fragments of insects and spiders that were dropped by the wasp larvae feeding in the cells above.
