Two new species of Marphysa Quatrefages, 1865 (Polychaeta: Eunicida: Eunicidae) from northern coast of China and redescription for Marphysa orientalis Treadwell, 1936

Abstract

Two new species of Marphysa Quatrefages, 1865 (Polychaeta: Eunicida: Eunicidae), M. bulla n. sp. and M. maxidenticulata n. sp., are described from the northern coast of China with comments on the usefulness of pectinate chaetae to separate species. A redescription of Marphysa orientalis Treadwell, 1936 originally described from China is given. The genus Marphysa is widely collected for bait for recreational fishermen and anglers in China and is also exported to Australia and Japan, yet the number of species involved or their native distribution are currently unknown. It is critical that aquaculture programs know which species they are attempting to breed and their native distributional ranges. A key to all described species of Marphysa from China, including two new species described in this paper is given.

Digging the diversity of Iberian bait worms Marphysa (Annelida, Eunicidae)

“…Since M. sanguinea redescription [29], two new species of the sanguinea-group were described from European and nearby locations, M. victori from the Bay of Biscay [3] and M. aegypti from the eastern Mediterranean, Suez Canal and Gulf of Suez [31], while we are here describing two more from the Bay of Cádiz. Similar situations occurred in other well studied coasts, such as Australia [29,52], South Africa [30], the Grand Caribbean [77], China [33,34] and Hong-Kong [51], where the presence of M. sanguinea proved to result from misidentifications or from a wrong use of the "cosmopolitan species" concept. Accordingly, several species (many new, some recovered from synonymies) have been reported, while others are still waiting to be reanalysed, likely to have their status removed from synonymy.…”

“…Bathymetrically, they occur mainly from intertidal to shallow subtidal depths, while the few species described from shelf to bathyal depths are generally poorly known and thus need further revision. Many intertidal species are a valuable biological and economical resource, widely used and highly appreciated as fishing baits for many decades in the Iberian Peninsula [13], but also elsewhere [3,[21][22][23][24][25][26][27][28][29][30][31][32][33][34], being commonly known with the vernacular names of "rosca" or "gusana de sangre" in Spanish, or "blood worm", "rock worm" or "clam worm" in English. This includes the type species, M. sanguinea, originally described from Devon, UK and recently redescribed based on a neotype from a nearby locality [29,35,36].…”

The commercialization and use of exotic baits in recreational fisheries in the north‐western Mediterranean: Environmental and management implications

“…(J. Gil, pers. observ., April 2014; Liu et al, ). For instance, Lumbrineris latreilli Audouin & Milne Edwards, 1833, generally referred to as bait used in the Iberian Peninsula (e.g.…”

“…In fact, several recent papers have provided up‐to‐date information on bait species status and taxonomy, including the description of new species (e.g. Arias et al, ; Arias & Paxton, ; Berke et al, ; Glasby et al, ; Kawauchi & Giribet, ; Liu, Hutchings, & Sun, ; Luttikhuizen & Dekker, ; Saito et al, ). In addition, in some cases one single species can be sold as different bait varieties: this is the case for the Korean ragworm ( P. linea ), which can be found in fishing shops under different names (i.e.…”

The complete mitochondrial genome of the polychaete, Marphysa tamurai (Eunicida, Eunicidae)

“…Marphysa is one of the nine genera in the family Eunicidae of Polychaeta (Zanol et al 2014). It comprises about 60 species in the genus Marphysa and is widely used for bait known as blood worms by recreational fishermens (Saito et al 2014;Zanol et al 2014;Liu et al 2017). Most of the Marphysa species are large-sized with high economic value and are traded as a commodity (Li et al 2016).…”
