Type material. The types are unkown (Moll 1941). A neotype was selected by Moll (1941) from Quatrefages´collection in the Muséum National d´Histoire Naturelle (MNHN-IM-2000-32924) and although not marked, Turner (1966) considered it to be the neotype selected by Moll (1941) because it was the only specimen with pallets from the type locality.
Type locality. Pasajes Port, San Sebastian, Spain (43° N 19´; 1° W 54´); Atlantic Ocean.
Material examined. Pallets of the specimens barcoded by Borges et al. (2012) were compared with pallets of Lyrodus pedicellatus obtained by Borges (2014) from Portsmouth, England (n= 210); Terceira, Azores, Portugal (n= 341); and Olhão, Portugal (n= 231). In addition, they were compared with pallets of Lyrodus mersinensis sp. nov. (see details above) and with the neotype, using a high-quality micrograph provided by the Muséum National d´Histoire Naturelle, Paris, France (Fig. 5).
Morphological diagnosis. Pallets non-segmented. Calcareous portion of blade composed of a single thick piece, distally conical. Distal half of the blade composed by a loose-fitted periostracum, more or less straight-sided, sometimes extending as lateral horns; distal margin concave to U-shaped. Periostracum varying from light brown to nearly black (Turner 1971).
Molecular diagnosis. COI sequences yield 34 molecular diagnostic characters between position 19 and position 640 (Table 5). 28S rRNA sequences yield three molecular characters in positions 463(T), 586 (T), 719(G) (Table 6).
Distribution. Reported as occurring worldwide (Turner 1966; Turgeon et al. 2009; Borges et al. 2014a).
Habitat. Marine; from the intertidal to depths down to 37m (Turgeon et al. 2009); wood-boring organisms.
