Biarticulata tuberculata (Hansen, 1913) Leptognathia tuberculata Hansen, 1913: 82 –83, plate VIII figs 3a–f. Kudinova-Pasternak, 1966: 532 [uncertain synonymy]. Kudinova-Pasternak, 1970: 353 [uncertain synonymy]. Biarticulata tuberculata (Hansen, 1913): Larsen & Shimomura, 2007: 19. Remarks. This somewhat enigmatic species, originally described by Hansen ( op.cit. ) from material collected in the Davis Strait at depths of 2194–2625 metres has also been reported from the Kurile-Kamchatka Trench at 4895 metres by Kudinova-Pasternak (1970) and the central North Pacific, 6051 metres (Kudinova-Pasternak 1966). It is very doubtfully placed in the Leptognathiidae as it is clearly either a species of Akanthophoreus or Chauliopleona , although it escaped the revision of both genera (the former as Paraleptognathia Kudinova-Pasternak, 1981) by Guerrero-Kommritz (2004, 2005). It is a very slender species, one syntype from Ingolf Station 36 having a carapace 1.8 times as long as broad and with pereonites 2–5 all longer than broad. For additional comments on this species and Kudinova-Pasternak’s record see Bird, elsewhere in this publication.
