Remarks
Morphological characters of the present specimen, including the carapace armature (
Figure 6
(a,)), the striations on thoracic sternites and pleonal tergites (
Figure 6
(c)), the relative lengths of spines on the antennal peduncle articles 1 and 2 (
Figure 6
(e)), and the armatures of Mxp3 (
Figure 6
(e)) and P3–4 (
Figure 6
(g–)), fall within the range of intraspecific variations of the
type
material from
Vanuatu
(
Macpherson 2009
) and subsequently reported material from south-western
Japan
(
Osawa 2012
).
Geographical distribution
Vanuatu
(
Macpherson 2009
), Ryukyu Islands, south-western
Japan
(
Osawa 2012
),
Mayotte Island
, south-western Indian Ocean (
Poupin et al. 2022
), Andaman Islands,
India
(present study); bathymetric range:
32–123 m
depth (
Macpherson 2009
;
Osawa 2012
). The present occurrence of
R. vittata
in the eastern Indian Ocean suggests that the species is widely distributed in the Indo-West Pacific although literature records are still scattered.
