Oospira (Formosana) formosensis, Nordsieck 1997: 11.

Type locality.

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

Material examined.

Lectotype. Formosa, coll. Swinhoe (NHMUK 1866.5.9.5/1), new designation, 26.1 × 7.0 mm, whorls 10.

Paralectotypes. Formosa, coll. Swinhoe (NHMUK 1866.5.9.5/2-3, 2 shells). Formosa, from collection of H. Adams (NHMUK 1878.1.28.245, 1 shell).

Remarks .

The specimen corresponding well in size with the measurements of Adams (1866) is designated as the lectotype for the stabilization of the name (ICZN 1999: Art. 74). Adams (1866) described the locality as Takow, Formosa. This species has recently been recorded by Hsieh et al. (2013) in the Liu-gui and Mei-nong areas in eastern Kaohsiung City, which were visited by Swinhoe during his collection trip through southern Taiwan. This species was unlikely to have been collected in Takow (coastal areas of Kaohsiung City in 1866). Apparently, Swinhoe or Adams used Takow to represent an area approximating present-day Kaohsiung City. The same situation was also observed for the type locality of Platryhaphe swinhoi and Dioryx swinhoei .
