Conus aristophanes
G. B. Sowerby
II
(
Fig. 1P–S
)
Localities:
Agatti, Amini, Androth, Bitra, Chetlet, Kadmat, Kalpeni, Kavaratti, Kilton and Minicoy
Habitat:
Rocky intertidal, lagoons, inner reef platform, sea grass bed, sandy shores
Depth:
0.2–
8 m
Specimens examined, observed:
20, 137
Length:
18–27 mm
Remarks:
This is the first report of
C. aristophanes
from
India
, and a new distribution record for the central Indian Ocean. The species-level distinction between the largely sympatric
C. coronatus
and
C. aristophanes
remains uncertain.
Cernohorsky (1964
,
1978
) pointed out consistent shell morphological differences between them in
Fiji
. The most striking of these is fewer spiral striae on the sutural ramps: 1–2 vs.
4–7 in
C. coronatus
(see
Fig. 1Q
).
Puillandre
et al
. (2014
:
Fig. 2
) reported a genetic distance of about 10% between the two based on three mitochondrial genes, a disparity that usually indicates species-level distinction. Prior to that study,
Röckel
et al.
(1995)
and
Coomans
et al.
(1981)
had concluded conspecificity based on morphology. We tentatively consider them distinct, but further study remains necessary.
