Remarks

Comparison with similar species

See remarks under A. sp. 3.

Condition of the specimen

In A. sp. 4, one leg, one fore and one hind wing are missing. Four legs, one fore and one hind wing are detached. The distal flagellomeres of both antennae are deformed. Most of the metasoma is missing, thus the body length measurement is not precise. Aphanogmus sp. 4 is deposited in the ZFMK as ZFMK- HYM-00037051.
