“…Endurance once in the hook and catch selectivity have thus made the species of Marphysa sought and popular fishing baits everywhere in the world for such a long time. Scientific records of this particular use are known from Australia [29,35], China [33,34], Egypt [31], England and the English Channel [25,113], the French Atlantic [3] and Mediterranean coasts [21], Japan [23,24,26,27], Malaysia [32,114], South Africa [30], Sri Lanka [28], or Zanzibar [22]. However, our results emphasize the importance of knowing how many species are being currently traded under the name "M. sanguinea", not only in the Iberian Peninsula, but also in Europe and all around the world [1,13].…”

“…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].…”

During a visit to polychaete-rearing facilities in the vicinity of Bay of Cá diz (SW Iberian Peninsula, Atlantic Ocean), we sampled two populations of Marphysa (Annelida, Eunicidae) originally occurring at nearby intertidal soft bottoms, one being more than twice as long as the other at the same age. We analysed them using partial sequences of two mitochondrial genes, 16S rDNA and Cytochrome Oxidase I, and classical morphological observations. Our molecular results confirmed that the two populations corresponded to two different species, with PTP species delimitation values ranging from 0.973 (long-bodied species) to 0.999 (short-bodied species). Morphologically, the short-bodied species resembles the recently redescribed M. sanguinea (Montagu, 1813), but differs mainly in having some parapodia with two subacicular hooks (one bidentate and one unidentate) and three types of pectinate chaetae, Two isodont present all along the body, and one particularly large anodont asymmetric appearing only from mid-posterior parapodia. The long-bodied species resembles Marphysa aegypti Elgetany, El-Ghobashy, Ghoneim and Struck, 2018 both in size and in having very robust, unidentate subacicular hooks (single in most parapodia, two-both similar in size and form-in some posterior parapodia), but differs, among other features, in the maxillary formula, the number of acicula per parapodia and the number and shape of pectinate chaetae. Accordingly, we are here fully illustrating and formally describing the two Iberian populations as Marphysa gaditana sp. nov. (short-bodied) and Marphysa chirigota sp. nov. (long-bodied) and we are emending the description of M. aegypti based on our revision of the type material. Also, we discuss on the distribution of the species of the sanguinea-group and on the relevancy of taxonomically robust studies when dealing with species of commercial interest having the potential of being globally spread through human activities, as well as on the misunderstandings caused by the incorrect use of the "cosmopolitan species" concept.

Saito, H., Kawai, K., Umino, T. and Imabayashi, H. 2014. Fishing bait worm supplies in Japan in relation to their physiological traits. Memoirs of Museum Victoria 71: 279-287.Market research was conducted from 2009 to 2013 to investigate the supply of live worms for fishing bait in Japan. We obtained 25 types of live fishing bait worms, including 16 species of polychaete, 1 species of echiuran, and 1 species of sipunculid. These were divided into three groups according to their country of origin: 1) worms supplied from native populations, five species (Perinereis wilsoni, Hediste diadroma, Kinbergonuphis enoshimaensis, Pseudopotamilla occelata, and Hydroides ezoensis), 2) worms supplied from both native and non-native populations, three species (Marphysa cf. iwamushi, Halla okudai, and Urechis unicinctus), and 3) worms supplied from non-native populations, 10 species (Perinereis linea, Alitta virens, Nectoneanthes uchiwa, Namalycastis rhodochorde, Glycera nicobarica, Diopatra sugokai, Marphysa cf. tamurai, Marphysa cf. mossambica, Scoletoma heteropoda, and Sipunculus nudus). Salinities in which no mortality of nereid worms occurred was 5-35 psu in Alitta virens, 5-30 psu in Namalycastis rhodochorde, and 10-35 psu in Perinereis linea. Worms living in temperate areas had a wide temperature tolerance of 5-30 °C in Alitta virens, Perinereis linea, Glycera nicobarica, Marphysa cf. iwamushi, and Scoletoma heteropoda. Tropical species (Namalycastis rhodochorde and Marphysa cf. mossambica) could not survive above 20 °C.

Molecular phylogenetic analyses were conducted to clarify how genetically homogeneous the common Japanese species of Marphysa known as Iwa-mushi is. This is a well-known polychaete used as a fishing bait that was first described as Marphysa iwamushi Izuka, 1907 (type locality: Japan and Taiwan) and later synonymized to Marphysa sanguinea (Montagu, 1813) (type locality: England). The nucleotide sequences of a nuclear gene (18S rRNA) and two mitochondrial genes (16S rRNA and cytochrome c oxidase subunit I (COI)) were compared between specimens newly collected from 14 localities in Japan including commercially sold fishing baits and DDBJ/ENA/GenBank data for congeneric species. Our results show that the Japanese Iwa-mushi is not a single species but a species complex comprising five genetically well-separated clades that were tentatively designated as five undetermined species (Marphysa spp. A, B, C, D, and E). It is unclear whether any of these species corresponds to M. iwamushi. The COI nucleotide sequence of Marphysa sp. A was almost identical to that of M. victori Lavesque, Daffe, Bonifácio & Hutchings, 2017 (type locality: France) and M. bulla Liu, Hutchings & Kupriyanova, 2018 (type locality: China), suggesting that they are conspecific and supporting the hypothesis of Lavesque et al. (2017) that the population in France was introduced from Japan. The COI sequence of Marphysa sp. B corresponds to that of M. maxidenticulata Liu, Hutchings & Kupriyanova, 2018 (type locality: China). Marphysa sp. E was found only in Tokyo Bay and may be an alien species that was introduced by importing live fishing bait. Our results indicate that the European species M. sanguinea is not distributed in Japanese waters.
