Dicharax aspidentatus Gittenberger, Choki Gyeltshen & Sherub Sherub in Gittenberger et al., 2024: 199, figs 18, 21, 45.

Type locality

“between Duenmang Tsachu and Gongphu Zero Point, 24 km SE of Zhemgang, 335 m a.s.l., 27°02’N 90°48’E, scree in warm broadleaf forest” (Bhutan).

Differential diagnosis

Probably the most similar species is D. rugosus due to the similar shell and aperture shape as well as rib density. However, that species has a shorter distance between the inner and outer peristomes and has a wider umbilicus. For the differences with other Bhutanese species see Gittenberger et al. (2024).
