Nanina (Acusta) assimilis H. Adams, 1866: 316, pl. 33 fig. 1.

Acusta assimilis, Chang 1984: 18.

Type locality.

Takow, Formosa [northern Qi-Jin, Kaohsiung City] (Swinhoe)

Material examined.

Lectotype. Formosa, coll. Swinhoe (NHMUK 1866.5.9.11/1), new designation, 13.7 × 19.4 mm, whorls 5.75.

Paralectotypes. Formosa, coll. Swinhoe (NHMUK 1866.5.9.11/2-3, 2 shells).

Remarks.

Adams (1866) described the locality as Takow, Formosa, but the original label has only "Formosa". The lot NHMUK 1866.5.9.11 was first registered and labelled as " Nanina propinqua ", then later published as Nanina assimilis . None of these shells exactly match with the measurements of Adams (1866). The specimen in the best condition is designated as the lectotype for the stabilization of the name (ICZN 1999: Art. 74).
