Remarks

The species is characterized by a subsutural row of rounded knobs. This is not found in any species of Leucosyrinx or Comitas , but on the contrary present in all species of Sibogasyrinx and Comispira . In shell shape and sculpture the species is quite similar to Comispira mai (Li & Li, 2008) ( Kantor et al. 2018: fig. 2a–c), differing in a slightly shorter shell and larger knobs on the shell periphery. Therefore, we transfer Surcula obtusigemmata to Comispira .

Conchologically, the species is very similar to Comispira subsuturalis (von Martens, 1901) and both species can be conspecific. Presently, we recognize both species as valid due to significant distance between collecting sites – East Africa for C. subsuturalis and Indonesia for C. obtusigemmata .

Schepman (1913) cited erroneously the longitude of stn 76 as 180°16.9′ E. The coordinates provided here corresponding to the Macassar Strait were taken from Tydeman (1902).

Distribution

Indonesia, 472–1788 m.
