Sarica [sic] resplendens – Fischer 1973: 92.

Diagnosis

Shell depressed, large (shell width 22.1 mm, shell height 10.5 mm), rather thin, semi-translucent and pale yellowish brown. Shell surface smooth and glossy; more glossy below the periphery; suture impressed; spire slightly elevated. Entire shell consisting of 6½ regularly increasing whorls. Periphery of body whorl rounded. Aperture obliquely oval-lunate shaped; peristome simple. Columellar margin simple and slightly reflected near umbilicus. Umbilicus narrowly opened and deep.

Material examined

CAMBODIA • 1 shell; H. Adam ex. Godwin-Austen collection; NHMUK 1903.7.1.112.

Remarks

Sarika resplendens is a widely distributed species and has been recorded throughout mainland Southeast Asia ( Collinge 1903; Fischer 1973; Schileyko 2011; Inkhavilay et al. 2019). This species is found commonly in Thailand (Pholyotha personal observation) and Laos ( Inkhavilay et al. 2019). Godwin- Austen (1883: 110, pl. 26, fig. 2) first reported this species from Cambodia without a precise location. The description of this shell morphology agrees well with the typical S. resplendens from Myanmar (see Pholyotha et al. 2020 for comparison), and we provide a brief description herein based on this specimen. Later, Fischer & Dautzenberg (1904: 395) mentioned the specimen identified as S. resplendens from “Kébal-Roméas, Cambodge (Pavie)”, without illustration. We have visited this limestone outcrop, Phnom Kbal Romeas, and found one Sarika species that clearly differs from S. resplendens s.s. and is described herein as a new species (for further comparison with this species see under S. lactoconcha Pholyotha & Panha sp. nov.).
