Genus Trenchia Knudsen, 1964

Type species

Trenchia wolffi Knudsen, 1964 (original designation), Recent, Kermadec Trench.

Remarks

Species of Trenchia closely resemble those of Xyloskenea Marshall, 1988 , but the latter differ in having distinct spiral sculpture on the initial part of the protoconch. In Trenchia the protoconch is smooth ( Warén & Bouchet 1993; Hoffman et al. 2020). Although the protoconch of the material discussed below is somewhat eroded, no spiral sculpture is evident and for this reason I refer the new species to Trenchia . This appears to be the first record of the genus from the Indian Ocean.
