Type locality.
"Kelantan, Malay Peninsula" (from the title).
Material examined.
Kelantan, NHMUK 20160061 (1 syntype); Kelantan, coll. Möllendorff , SMF 158410 (6 shells); Malaysia, Kelantan, rd. #8 Gua Musang, Kuala Lipis, left side off km19, ex coll. Hemmen, coll. PGB (4 shells; they are similar to the syntype but narrower).
Remarks.
Protoconch spirally striated at its very beginning and this sculpture turns to a rather finely granulated surface until the end of the protoconch (in case of Metalycaeus species the first 0.5-1.0 whorl is usually without spiral lines); R1 rather irregularly ribbed with somewhat weaker spiral striation; R2 very short, with ca. seven low ribs. The SMF 158410 sample contains three shells with prominent spiral structure and another three shells with only very slight indication of spiral lines.
