Remarks

Comparison with similar species

Aphanogmus sp. 1 can be distinguished from all other treated species by the absence of the preoccipital furrow, the intertorular carina and the preoccipital carina.

For more comparisons with similar species, see remarks under A. mariae sp. nov.

Condition of the specimen

In A. sp. 1, the left pedicel, the left flagellum, the left hind wing, all left legs, and the right fore and hind legs (except coxae), and the apical part of the left harpe are missing. The metasoma is deformed, thus the body length measurement is not precise. Also, the gvc is slightly deformed, especially in its basal part, which is covered with metasomal tissue. The setal arrangement of the male genitalia is very difficult to see, thus some setae characters are not described. Aphanogmus sp. 1 is deposited in the ZFMK as ZFMK-HYM-00037054.
