Material examined

Syntypes

CAMBODIA • 2 shells; Battambang Province; NHMUK 1893.2.4.1076–1077 .

Other material

CAMBODIA • 13 shells; Battambang Province, Banan District, Phnom Sampov, Samov Mountain , locality code C072; 13°01′33.60″ N, 103°06′03.64″ E; CUMZ 7900 .

Remarks

The distribution of S. bocourti is currently known only from the type locality in Battambang, Cambodia ( Fig. 1 ). In this survey, no living specimens have been collected from the type locality.

Sarika bocourti differs from S. resplendens (specimen NHMUK 1903.7.1.112 from Cambodia) with the last whorl obtusely angulated on the periphery, while the shell in S. resplendens has a rounded periphery.
