A First Record of the Genus Parastilomysis (Crustacea: Mysida: Mysidae) from Korea

Abstract

A mysid species, Parastilomysis paradoxa Ii, 1936 belonging to the subfamily Mysinae Hansen, 1910 which comprises approximately 90% of all mysid species, is newly reported from Korean waters. The genus Parastilomysis Ii, 1936 which is also new to Korea, is distinctly different from other genera by having biramous third and fourth pleopods of the male, and telson with an apical cleft. In the present paper, authors provide detailed descriptions and illustrations of P. paradoxa based on the specimens collected from the southern coast of the Korean peninsula, and also discuss on the zoogeographical distribution herein. Parastilomysis paradoxa belongs to Mysidae Haworth, 1825, and is the 50th species in Korea

The complete mitochondrial genome of the bait worm, Marphysa victori (Annelida; Polychaeta; Eunicida; Eunicidae)

“…Members of Marphysa (Annelida; Polychaeta; Eunicida; Eunicidae) generally inhabit intertidal shores and are widely used as bait in recreational and commercial fishing ( 1 ). A bait worm ( 1 ) was recently recorded in Korean coastal water ( 2 ). This polychaete plays critical roles in circulating seawater through the sediment and purifying the sediment by its feeding activities in the benthic ecosystem ( 3 ).…”
