Treatment

Alycaeus (Dioryx) swinhoei H. Adams, 1866: 318, pl. 33, figs 11, 11a.

Alycaeus swinhoei - Reeve 1878: pl. 3, species 21.

Dioryx swinhoei - Kobelt and Möllendorff 1897: 147; Kobelt 1902: 340; Hsieh et al. 2006: 88 + figures; Hwang 2014: 8, fig. 1F.

Type locality.

"Takow, Formosa".

Material examined.

Formosa, NHMUK 1866.5.9.8 (lectotype, designated by Hwang 2014); Same data, NHMUK 1866.5.9.9 (1 paralectotype); Formosa: Sammaipo, leg. Hirase, 1906, 1378a (probably locality code of Hirase), coll. Jetschin ex coll. K.L. Pfeiffer, SMF 109780 (2 shells).

Remarks.

Both the lectotype and the paralectotype were strongly weathered. Protoconch without notable sculpture; R1 with some radial sculpture; R2 short, with alternating narrow/lighter and thicker/darker stripes, overall surface smooth. The specimens deposited in the Senckenberg Museum were not weathered, and the sculpture could be examined in more detail: protoconch rather glossy, R1 with very fine, irregular radial lines and weak spiral striation.
