Synonymy. Lyrodus pedicellatus  Mediterranean form ( Borges et al. 2012), L. pedicellatus  II ( Weigelt et al. 2016), Lyrodus pedicellatus  Turkey ( Treneman et al. 2018).

Type material. Holotype: specimen with pallets (MNHN IM-2000-33821); BOLD ID: WBET133, project “ Wood Boring Mollusca from Europe ”, publicly available in the BOLD System  ; DNAAbout DNA voucher stored deep frozen (-80°C) at the University of Minho , Braga, Portugal  . Paratypes: three specimens (MNHN IM-2000-33822, MNHNIM-2000- 33823, MNHN-IM-2000-33824); BOLD IDs: WBET130; WBET134; WBET135. All specimens were collected at the type locality, preserved in 96% ethanol and stored at 4°C at the Institute for Coastal Research, Helmholtz-Zentrum Geesthacht, Germany  . The types are deposited at the Muséum National D´ Histoire Naturelle in Paris , France  .

Type locality. Mersin Bay, Mersin, Turkey (36° N 48´; 36° E 38.4´); Mediterranean Sea.

Other material examined. Morphology of the pallets of specimens obtained by Borges (2014) from Mersin, Turkey (n = 127) and Rovinj, Croatia (n = 301).

Morphological diagnosis. The morphologic characters are identical to those of Lyrodus pedicellatus  (see below) according to Turner (1966; 1971).

Molecular diagnosis. COIAbout COI sequences yield 32 molecular diagnostic characters between position 61 and position 658 ( Table 3). 28S rRNA sequences yield eight molecular characters in positions 111(T), 112(T), 450(G), 708(T), 714(C), 759(A), 1248(T), and 1262(G) ( Table 4). BIN BOLD: AAO8110 (n = 4), including the holotype. Intraspecific variation: 0.4%; closest neighbour species: Bankia carinata  at a genetic distance of 19.3% and Lyrodus pedicellatus  at a genetic distance of 19.9%.

Etymology. Named after the type locality, Mersin, south of Turkey.

Distribution. Currently known only from the type locality, but probably widespread in the Mediterranean and possibly the Black Sea ( Borges et al. 2014a).

Habitat. Marine; wood-boring organisms.
