Raphaulus [sic] Raphaulus chrysalis - Stoliczka 1871: 151, farm caves, near Moulmein, Myanmar.

Type material examined.

Possible syntype NHMUK 2013.04.16 (1 shell; Fig. 14B ) from Siam.

Other material examined.

NHMUK 1871.9.23.52 (1 shell; Fig. 14C ) from Burma. NHMUK 1903.7.1.3073 (2 shells; Fig. 14D ) from Molmein.

Diagnosis.

Shell ovate; body whorls slightly bulging. Tube cylindrical, pointing upward and backward.

Differential diagnosis.

Rhaphaulus chrysalis is most similar to R. lorraini in shell shape, but differs in having a cylindrical tube pointing upward and backward, instead of forward as in R. lorraini .

Distribution.

Northeastern India, Myanmar, and an uncertain record from Thailand ( Páll-Gergely et al. 2014).

Remarks.

No material of this species was found during this survey, and the record in Thailand needs further confirmation. The type locality on the label of the possible type specimen is “Siam”, which is different from that reported in the original description as “Arva”. A lack of a tube in a possible syntype NHMUK 2013.04.16 (Fig. 14B ) is possibly due to damage.
