Borges L.M., Treneman N.C., Haga T., Shipway J.R., Raupach M.J., Altermark B. & Carlton J.T. 2022. Out of taxonomic crypsis: A new trans-arctic cryptic species pair corroborated by phylogenetics and molecular evidence. Molecular Phylogenetics and Evolution 166: 107312. DOI:10.1016/j.ympev.2021.107312
Abstract [+] [-]Cryptic species are a common phenomenon in cosmopolitan marine species. The use of molecular tools has often uncovered cryptic species occupying a fraction of the geographic range of the original morphospecies. Ship worms (Teredinidae) are marine bivalves, living in drift and fixed wood, many of which have a conserved morphology across cosmopolitan distributions. Herein novel and GenBank mitochondrial (cytochrome c oxidase subunit I) and nuclear (18S rRNA) DNA sequences are employed to produce a phylogeny of the Teredinidae and delimit a cryptic species pair in the Psiloteredo megotara complex. The anatomy, biogeography, and ecology of P. megotara, Psiloteredo sp. and Nototeredo edax are compared based on private and historic museum collections and a thorough literature review. Morphological and anatomical characters of P. megotara from the North Atlantic and Psiloteredo sp. from Japan were morphologically indistinguishable, and differ in pallet architecture and soft tissue anatomy from N. edax. The two Psiloteredo species were then delimited as genetically distinct species using four molecular-based methods. Consequently, the Northwest Pacific species, Psiloteredo pentago nalis, first synonymized with N. edax and then with P. megotara, is resurrected. Nototeredo edax, P. megotara and P. pentagonalis are redescribed based upon morphological and molecular characters. Phylogenetic analysis further revealed cryptic species complexes within the cosmopolitan species Bankia carinata and possibly addi tional cryptic lineages within the cosmopolitan Lyrodus pedicellatus.

Abstract [+] [-]Jouannetia (Pholadopsis) spinosa n. sp. is described as the second species in the West Pacific and the sixth species of the subgenus Pholadopsis. It lives in weakly consolidated mud and sand blocks obtained from relatively deep waters in Japan and the Philippines. J. (P.) spinosa n. sp. is characterized by a small spherical shell with dense spiny sculpture, remarkably concave posterior portion of the anterior slope, a siphonoplax with claw-like spines on the posterior margin, and red pigmentation on the translucent mantle collar at the base of the siphon. It bas been collected from depths ranging from 50 to 180 m, and shows a marked difference in depth range compared to the intertidal congener Jouannetia (Pholadopsis) globulosa in the West Pacific. The structure of the mesoplax in the subfamily Jouannetiinae is also discussed in detail.
