Type material

Lectotype INDONESIA • Ceram Sea; 2°40′ S, 128°37.5′ E; depth 835 m; ZMA 136887.

Remarks

The type series consisted of 12 specimens collected from the same station. Later, Shuto (1970b) observed that the series actually included three different species and described two of them based on the syntypes, Makiyamaia sibogae Shuto, 1970, and Lucerapex schepmani Shuto, 1970 . Shuto applied the name Schepmania gen. nov. variabilis to three specimens. However, the genus was later renamed as Shutonia due to homonymy (van der Bijl 1993).

Examination of the photograph of the largest specimen (illustrated by Schepman 1913: pl. 28 fig. 1a) revealed that it possesses a subsutural row of nodules, more prominent on the upper whorls, which is characteristic of Sibogasyrinx and Comispira but not of other genera of Conoidea . Therefore, we transfer the species to Sibogasyrinx, rendering Shutonia a junior synonym.
