Hemiphaedusa exilis, Kuroda 1941: 140.

Type locality.

Tamsui, Formosa [Danshui, New Taipei City] (Swinhoe).

Material examined.

Lectotype. Formosa, coll. Swinhoe (NHMUK 1866.5.9.4/1), new designation, 27.0 × 7.1 mm, whorls 10.

Paralectotypes. Formosa, coll. Swinhoe (NHMUK 1866.5.9.4/2-3, 2 shells). Formosa, from collection of H. Adams (NHMUK 1878.1.28.207, 2 shells).

Remarks.

Adams (1866) described the locality as Tamsui, Formosa, but the original label has only "Formosa". The specimen corresponding well in size with the measurements of H. Adams (1866) is designated as the lectotype for the stabilization of the name (ICZN 1999: Art. 74).
