Material examined. Australia, Christmas Island, Dolly Beach, stn 15, 10°31.53’S, 105°40.44’E, 21 February 1987, coll. L.M. Marsh and S.M. Slack-Smith —one complete specimen with damaged ventral beak (WAM Z59479). Depth range. 12–25 m. Remarks. Although the material is very limited and poorly preserved, without possibility to investigate internal structure, we can assign this specimen to Thecidellina blochmanni as it is the only thecideide species reported from Christmas Island which is its type locality. In the opinion of Simon et al. (2018) the specimens from the Red Sea described by Logan & Bitner (2013) as T. blochmanni represent another species, thus Christmas Island seems to be the only locality of this species (Marsh & Fromont 2000; Logan et al. 2015; Simon et al. 2018).
