Rauschert & Arntz (2015: 59, pl. 52) give a photograph of an Acanthonotozomella cf. trispinosa, which might be a species distinct from the true A. trispinosa. In the archives of RBINS, there is an annotated copy of this photograph. It indicates that the specimen is 6 mm long and was collected at the station 293 of ANT-XXI/2. The coordinates of stn 293-1 are 72°51.90ʹ S, 19°39.31ʹ W to 72°48.65ʹ S, 19°39.62ʹ W (eastern shelf of the Weddell Sea), 518– 542 m.
