Cycloryx pemaledai Gittenberger & Sherub, 2022, which was described from northwestern Bhutan, is reported for the first time in Sikkim, India. That species differs from all its congeners by the short R3 (the region between the constriction and the peristome). The differences between the Bhutanese and Indian shells are minimal, therefore the Indian shells are identified as Cycloryx cf. pemaledai. Furthermore, Alycaeus himalayae n. sp. is described from Arunachal Pradesh. This is so far the only Alycaeus species inhabiting the Himalayas, and thus, its discovery is a real surprise.
