Remarks

Comparison with similar species

Aphanogmus sp. 2 can be distinguished from all other treated species by the combination of the apicoventrally finger-shaped and slightly broadened and rounded apex of the harpe, the very long lateral and ventral setae of the harpe, and the high Weber length to genital length ratio. However, the male genitalia of A. sp. 2 are deformed and additional specimens would be very helpful to further strengthen delimitation of this species.

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

Condition of the specimen

In A. sp. 2, both antennae, both fore wings, and all legs except the right fore and hind leg are detached. The metasoma is deformed, thus the body length measurement is not precise. Also, the gvc is deformed, which affected specifically the left harpe and made some measurements or descriptions of male genitalia characters impossible (e.g., the gvc width to distal gvc width ratio). Aphanogmus sp. 2 is deposited in the ZFMK as ZFMK-HYM-00037055.
