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; 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

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.
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.
