Revision of the Arctic group of species of the family Elpidiidae (Elasipodida, Holothuroidea)

Marine Life in the Arctic

“…Similarly noteworthy are the fi nds of three new gastropod species in the Bering and Chukchi Seas (Chaban 2008 ;Sirenko 2009 ), two of which were actually collected over 70 years ago. All of these and other species, including several amphipods (B. Stransky, unpublished observations), cnidarians (Rodriguez et al 2009 ), and a sea cucumber (Rogacheva 2007 ), are in the larger and better studied size fractions. Considerably less taxonomic effort was spent on meiofaunal groups during ArcOD, but new species were recorded among benthic and hyperbenthic copepods (see, for example, Kotwicki & Fiers 2005 ), Komokiacea (O. Kamenskaya, unpublished observations), and the nematodes ( J. Sharma, personal communication).…”

Arctic Marine Biodiversity: An Update of Species Richness and Examples of Biodiversity Change

“…About 60% of the deep-sea taxa overlapped with shelf taxa . Recently, new Arctic benthic species were described from a broad range of taxa and regions, for example a pan-Arctic deep-sea sea cucumber (Rogacheva, 2007), three mollusks from the Chukchi Sea shelf (Chaban, 2008;Sirenko, 2009) polychaetes (Carr, 2010;Corstophine, 2010;Hardy et al, 2011). New Arctic fish species continued to be described in the first decade of this century, for example, Lycodes paamiuti (Møller, 2001) and Careproctus kidoi (Knudsen and Møller, 2008).…”

Taxonomy and distribution of the genusKolga(Elpidiidae: Holothuroidea: Echinodermata)

“…A detailed description of this species, including the type series, was published by Rogacheva (2007). One new paralectotype of this species was found in the SMNH collection: the specimen from Station 295 of 'Vøringen', the Norwegian North Atlantic Expedition, Catalogue Nr Type -4326, 71859 ′ N 11840 ′ E, This species differs by the dominance in tube feet and tentacles of rods (Table 2), curved, bent or rarely straight, with varying number of spines developed only at the ends of rods or also covering their other parts, up to the full length of rod (Rogacheva, 2007, Figure 11, pp.…”

“…Rods in the two other species are more uniform; they are curved with spines at the ends and show little variation ( Table 2). The Arctic species of the genus Elpidia also have differences in the tube feet ossicles (Rogacheva, 2007).…”
