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
).
