Diagnosis

This species is characterized by a conical shell and dense ribbing on the entire surface. The peristome is thin, but the umbilicus is slightly covered by a reflected outer peristome.

Type material examined

INDIA • 1 syntype of C. elegans (Fig. 21A–E); Shengorh Pk, Dafla Hills; Godwin-Austen coll.; NHMUK 1903.7.1.2594 • 1 syntype of A. khunhoensis (Fig. 21F–J); Khunho Peak, Naga Hills; Godwin-Austen leg.; NHMUK 1903.7.1.2520 .

Type localities

“Shengorh Peak, Dafla Hills” ( C. elegans); “Khunho Peak, Naga Hills” ( C. khunhoensis).

Remarks

This species is similar to C. constrictus, but is characterized by a thinner peristome and finer ribbing. Cycloryx granum has similar sculpture, but it is more globular in shape.

Cycloryx khunhoensis has slightly less dense ribbing than C. elegans, which we interpret as part of the intraspecific variability.
