Diagnosis

This species can be recognized based on the large, conical shell, and the weak sculpture. See also under Cycloryx rohiniae sp. nov.

Type material examined

INDIA • 1 syntype of A. otiphorus (see Preece et al. 2022: fig. 33e); no locality data; UMZC I.102555 • 12 syntypes of A. summus (Fig. 29F–J); Rechila Pk, W. Bhutan; Godwin-Austen leg.; NHMUK 1903.7.1.2573 .

Additional material examined

INDIA • single shell from the R. McAndrew collection (Fig. 29A–D); UMZC I.102560 • 1 shell of A. otiphorus; Darjiling; “compared with typical sp in Museum Cambridge”; NHMUK 1903.7.1.2565.

Type localities

“ad Pankabari (1000 ped. alt.) et in valle Rungun (4000 ped.) prope Darjiling Himalayanum” ( A. otiphorus); “Rechila Peak, Western Bhutan ” ( A. summus).

Remarks

Alycaeus summus is identical to A. otiphorus, therefore the former is a junior synonym of the latter. Unlike other members of this species group, A. otiphorus has a rather conical shell (instead of conical-globular), but it is classified here due to the expanded and reflected outer peristome.
