Dicharax bhucarinatus Gittenberger & Sherub Sherub, 2024

Fig. 75A–D

Dicharax bhucarinatus Gittenberger & Sherub Sherub in Gittenberger et al., 2024: 209, figs 27, 32.

Diagnosis

Differs from its congeners by the densely ribbed shell, and the keeled body whorl.

Type locality

“ Samdrup Jongkhar Dzongkhag: 7 km NNW of Daifam (= Jomotshangkha), Toka Phu, 940 m a.s.l., 26º57’N 92º04’E ” (Bhutan).

Differential diagnosis

As mentioned in the original description (Gittenberger et al. 2024), the only species of Alycaeinae in the region with a keeled body whorl is Chamalycaeus sculptilis, which has a beaded peristome. Nevertheless, D. bhucarinatus was described based on the corroded holotype and therefore, the sculpture could not be examined. Thus, it may belong to Chamalycaeus (more likely than Metalycaeus, as mentioned by Gittenberger et al. 2024).
