Tumidochelia dentifera G.O. Sars 1896

Tumidochelia cf. dentifera (G.O. Sars, 1896)

(restricted synonymy and bibliography)

Leptognathia dentifera G.O. Sars, 1896: 30, plate XIV fig.2. Kudinova-Pasternak, 1970: 353 [doubtful synonymy]. Tumidochelia dentifera (G.O. Sars, 1896): Larsen & Shimomura, 2007: 8, fig. 3.

Remarks. The genus Tumidochelia is an Akanthophoreus -like taxon, largely characterized by a relatively short antennule article 1 and inner spiniform process on the uropod basal article. The original diagnosis (and repeated by Larsen & Shimomura 2007 in the enlargement of the genus) is in error in stating that the cheliped carpal shield is on the inner face – it is on the outer face.

Tumidochelia dentifera, principally a shelf and shallow-bathyal species from west European waters (see Sieg 1983), has been doubtfully recorded from the Kurile-Kamchatka Trench (Kudinova-Pasternak 1970), at 4895–6225 metres while another species, T. knighti Larsen & Shimomura, 2007, has been recently described from bathyal depths (635–654 metres) off Okinawa.
