Dermestidae The South American fauna of Dermestidae, especially Trogoderma, is largely unstudied because several old type specimens need to be located and identified for revision. Only a few species can be identified with confidence because of their distinctive features. Five larval morphospecies found in the nests of A. annumbi provided identification of different adults as follows: Long black larvae [sp. 1] = Trogoderma sp. 1 Flat orange larvae [sp. 2] = Trogoderma sp. 2 Brown hairy larvae [sp. 3] = Trogoderma sp. 3 [black adults] Large orange larvae [sp. 4] = Trogoderma pectinicornis Reitter, 1881 Long orange larvae [sp. 5] = Trogoderma sp. 5 These larvae feed on dead insects found inside nests. The dead insect species used as food were present as hibernants and died inside (Table 2). In addition, other insect remains were present (see section III). Adults of Trogoderma can be distinguished from other Dermestidae genera by the presence of a median ocellus, and the segment I of tarsus III being longer than segment II (Kingsolver 1987).
