Remarks
. The colour pattern illustrated in the colour figure of
Dana (1852: pl. 15, fig. 1)
of a French Polynesian specimen depicts a series of red lines in a rather regular geometric pattern (Plate 3D). A similar pattern is shown in the drawings of western Indian Ocean specimens given by
Richters (1880: pl. 16, figs. 9, 10)
. Richter's illustrations, unfortunately, only showed the lines on the anterior part of the carapace. Photographs of preserved Vietnamese specimens in
Serène (1959: pl. 2, figs. A, B)
, however, show a very different pattern of thicker, diffuse and irregular redbrown lines much closer to those of
T. garthi
(see Galil 1983: fig. 9B). Examination of numerous live and preserved specimens from
French Polynesia
(
Castro 1997b
) and the western Indian Ocean (
Castro 1999b
) has demonstrated that the red lines on the carapace are typically sinuous and interconnected (Galil 1983: fig. 9C;
Serène 1984
: pl. 38, fig. E;
Castro 1997b
: pl. 1, fig. F [colour]) but they sometimes follow a more regular geometric pattern. Although all the available evidence points to the fact that recent records are conspecific with Dana's species, it would be better if a
neotype
is designated.
Dana's
type
material is lost. The
type
locality is Carlshoff
Island
(= Aratika
Island
) in the Tuamotu Archipelago,
French Polynesia
(
Dana 1852: 254
). A female (MNHNB 27681 [ex B 25319]; cl 8.3 mm, cw 10.7 mm) from Moruroa (Mururoa) Atoll (
21º50’S
,
138º50’W
), Tuamotu Archipelago (
Castro 1997b: pl. 1, fig. F [colour]
) is herein designated as the
neotype
. It was collected by J. Poupin and SMSRB divers from
Pocillopora
at a depth of
5–10 m
on
March 1996
.
