“…The haplotype network analysis was based on 79 sequences of 16S rDNA, of which 26 were previously obtained by Sato-Okoshi et al [ 21 ], Abe and Sato-Okoshi [ 23 ] and Almón et al [ 24 ]. The analysis recovered a single network comprising 15 haplotypes ( Figure 3 B, Supplementary Materials Table S5 ).…”

“…To map the distribution of P. hoplura , we considered reliable records made by earlier authors based on morphological features and records by Sato-Okoshi and Abe [ 17 ], Teramoto et al [ 18 ], David et al [ 19 ], Williams et al [ 9 , 20 ], Sato-Okoshi et al [ 21 ], Lee et al [ 22 ], Abe and Sato-Okoshi [ 23 ] and Almón et al [ 24 ] based on genetic data. Complete information on newly collected material, museum samples examined during this study and by other authors and records by other authors for which no museum deposits were noted are provided in Supplementary Materials Tables S1 and S3 .…”

The spionid polychaete Polydora hoplura Claparède, 1868 is a shell borer widely occurring across the world and considered introduced in many areas. It was originally described in the Gulf of Naples, Italy. Adult diagnostic features are the palps with black bands, prostomium weakly incised anteriorly, caruncle extending to the end of chaetiger 3, short occipital antenna, and heavy sickle-shaped spines in the posterior notopodia. The Bayesian inference analysis of sequence data of four gene fragments (2369 bp in total) of the mitochondrial 16S rDNA, nuclear 18S, 28S rDNA and Histone 3 has shown that worms with these morphological features from the Mediterranean, northern Europe, Brazil, South Africa, Australia, Republic of Korea, Japan and California are genetically identical, form a well-supported clade, and can be considered conspecific. The genetic analysis of a 16S dataset detected 15 haplotypes of this species, 10 of which occur only in South Africa. Despite the high genetic diversity of P. hoplura in South Africa, we tentatively propose the Northwest Pacific, or at the most the Indo–West Pacific, as its home region, not the Atlantic Ocean or the Eastern Pacific Ocean. The history of the discovery of P. hoplura around the world appears to be intimately linked to global shipping commencing in the mid-19th century, followed by the advent of the global movement of commercial shellfish (especially the Pacific oyster Magallana gigas) in the 20th century, interlaced with continued, complex dispersal by vessels and aquaculture. Given that P. hoplura has been detected in only a few of the 17 countries where Pacific oysters have been established, we predict that it may already be present in many more regions. As global connectivity through world trade continues to increase, it is likely that novel populations of P. hoplura will continue to emerge.

The spionid polychaete Polydora hoplura Claparède, 1868 has been widely recorded boring in shells of abalone, oysters, clams, barnacle tests and sponges in temperate and subtropical waters. Molecular studies have suggested conspecificity of individuals collected worldwide but showed high genetic variability of the species with the highest diversity of haplotypes in the South African population. We have compared the morphology and genetic data of shell-boring worms from Kuwait, which were previously assigned to P. hoplura, with American, Asian and European individuals, including those from the type locality in Italy. The Kuwaiti individuals share key diagnostic morphological characters with P. hoplura but differ in ochre pigment on the anterior chaetigers in life, pattern of pigmentation after fixation in formalin, and pattern of methyl green staining of fixed specimens. They also differ in the dimensions of mature spermatozoa. The analysis of sequence data of five gene fragments (total 3483 bp) showed that the intraspecific diversity of P. hoplura and the variability of Polydora individuals from Kuwait are less than the divergences in all studied genes, except for 28S rDNA, between these two groups. These data, as well as the absence of common cytochrome c oxidase subunit I (COI) and 16S haplotypes, and morphological differences between individuals from Kuwait and P. hoplura, allowed us to conclude that the Kuwaiti population is not conspecific with P. hoplura. This conclusion was confirmed by the results of the species delimitation analysis. In the Bayesian inference analysis of the sequence data individuals from Kuwait formed a well-supported clade sister to P. hoplura. These individuals are described and illustrated here as a new species, Polydora mohammadi sp. nov. Primers used for successful amplification of the mitochondrial COI gene in various species of Spionidae are reviewed and we suggest future studies on Polydora use a combination of two primer pairs (2F–spionid–LCO/1R–spionid–HCO and Dorid_COI.3F/Dorid_COI.1R) to target sequences that include the barcode fragments covered with “Folmer” and “Dorid” primers.
