| 英文摘要 | During an expedition to a seamount at Caroline Plate in the tropical Western Pacific,a new species of Tritonia was sampled from the upper bathyal zone at depth of 970-1 262 m.This new species,Tritonia iocasica sp.nov.,represents the first tritoniid nudibranch known to feed on octocoral of the family Melithaeidae.The species is up to 120 mm in length,pinkish in color;with the rhinophoral sheath divided into several petaliform extensions;veil with,about 18 elongate digitiform processes;notal margin with17-19 pairs of secondary gills;anus located below the 5~(th) and 6~(th) secondary gills,and the genitalia below the 3~(rd) secondary gill on the right side of the body.Based on these external features,T.iocasica sp.nov.can be dearly distinguished from all previously described members of the genus.Phylogenetic analyses of two mitochondrial(COI,16 S rRNA) and a nuclear(H3) genes using Bayesian inference,maximum likelihood,and species delimitation analysis also support the separation of T.iocasica sp.nov.from its congeners. |
