Remarks

Comparison with similar species

The male genitalia of A. sp. 3 are similar to those of A. sp. 4 in having finger-shaped and distomedially converging harpes. However, the harpes of A. sp. 3 are distinctly thinner and the lateral and ventral margins are not convex. Furthermore, the harpe/gvc index is lower in A. sp. 3 (0.18, compared to 0.29 in A. sp. 4).

Condition of the specimen

In the specimen, the right hind wing, right middle leg (except coxa), and the four distal tarsal segments of the left middle and hind leg are missing. Both F9 are deformed, and the head is deformed and detached. Also, the metasoma is deformed, thus the body length measurement is not precise. These deformations in the holotype made some descriptions and measurements of head and antennal characters impossible or not precise (e.g., head width to mesosoma width). Aphanogmus sp. 3 is deposited in the ZFMK as ZFMK-HYM-00037056.
