Treatment

Alycaeus satsumana Pilsbry, 1902b: 548-549.

Chamalycaeus satsumanus - Azuma 1982: 10, pl. 3, fig. 31.

Chamalycaeus satsumanus satsumanus - Minato 1988: 14.

Metalycaeus satsumanus - Páll-Gergely et al. 2017: 103, 104; Páll-Gergely and Asami 2017: 4.

Type locality.

"Kagoshima, Satsuma, Kiusiu".

Material examined.

Kagoshima, Satsuma, leg. Hirase, 1901, ANSP 81919 (lectotype, designated by Baker 1964, photographs examined); 鹿児島縣 1鹿児島市原良田 (Kagoshima-ken, Kagoshima-shi, Harara, Ta[?] = Kagoshima Prefecture, Kagoshima City, Harara, Ta[?]), coll. Sakurai, NSMT-Mo 79103 (3 shells).

Remarks.

Protoconch elevated, with spiral lines on its last whorl; R2 with ca. 22 widely spaced, low, blunt, regular ribs; the distance between the ribs at the edge of the body whorl is at least 2-3 × wider than the width of a rib; R1 with conspicuous spiral striation.

Alycaeus awaensis Pilsbry & Y. Hirase, 1904 and Alycaeus laevicervix Pilsbry & Y. Hirase, 1904 are classified as a subspecies of Chamalycaeus satsumanus by Minato (1988), which we also follow here. Sigmacharax tanegashimae was additionally classified under Chamalycaeus satsumanus in the same study, but these species belong to different genera according to our revision.
