Carepoctus solidus sp.n., a New Species of Liparid Fish (Scorpaeniformes, Liparidae) from the Lower Bathyal of the Polar Basin

  • N. V. Chernova

Abstract

A new species of snailfish, Careproctus solidus (Scorpaeniformes, Liparidae), is described from lower bathyal depth of the Polar Basin. The holotype and only known specimen is deposited in the Zoological Institute, Russian Academy of Sciences, St. Petersburg (ZISP 50626, immature female SL 117.5 mm). The fish was collected by the German-Russian expedition by RV “Polarstern” in 1993 on the continental slope of the northern part of the Laptev Sea (78°23.4 N, 133°09,5 E) at a depth of 2151-1934 m. C. solidus resembles the Arctic shelf species C. reinhardti (Krøyer) in counts, prickled skin, 0+2 pores in temporal canal, but differs in the oblique mouth, the pectoral fin in a low position, 3 (2+0+1) radials in the pectoral girdle, a small triangular opercular flap, round (not longitudinally oval) pupil, and a solid (ungelatinous) body. The relantionships of this unusially deep-living Careproctus species are unclear, but it is the second example of a unique liparid fish from the deep Polar Basins.
