Tumidochelia uncinata (Hansen, 1913) new comb.

Leptognathia uncinata Hansen, 1913

Material. Holotype, non-ovigerous female, (ZMUC CRU- 8518), Davis Strait, Ingolf Sta. 36, 61°50’N, 56°21’W, 2702 m. Paratype, 1 juvenile (ZMUC CRU- 9275), Ingolf Sta. 103, 66°23’N, 8°52’W, 1090 m.

Remarks. Leptognathia unicinata is transferred to Tumidochelia due to the special structure of the cheliped carpal shield and the biramous uropod with a spiniform process on the basal article. It also conforms to the other diagnostic characters: antennule article 1 shorter than rest of antennule, article 2 almost as long as article 1, and the pereopod 1 carpus shorter than merus.
