Larsen & Shimomura, 2007 : 15 . Remarks. As with the next species, L. vinogradovae has been removed from Leptognathia sensu stricto and the Leptognathiidae by Larsen & Shimomura (2007) . Its true generic and familial attributions remain unknown until new and unequivocal specimens are collected. It is an elongate species, with a long pleon and the uropods lack an exopod. It was originally recorded from the Kurile-Kamchatka Trench at 5240 metres ( Kudinova-Pasternak 1970 ), but is not recorded in the present material.
