Diagnosis.
Carapace smooth, without tomentum of setae. Rostrum with 4–6 lateral teeth; lateral gastric carina with supraorbital spine plus 2 teeth; submedian gastric carina with 1 or 2 teeth; median gastric carina without spines. Telson with 3 or 4 pairs of dorsal spines. Cheliped merus with 1–3 spines on upper margin, palm unornamented. Male pleopod 1 absent in small specimens, single article in adults.
Distribution.
Widespread in the Indo West-Pacific, from eastern Africa,
Western Australia
, northern
Australia
, to southern
Japan
and
French Polynesia
; to
91 m
depth (
Sakai, 2011
).
Remarks.
The new material contributes little to knowledge of this widespread and frequently taken species. The species was well illustrated by
Ngoc-Ho (1998)
.
Sakai (2011
: fig. 27C) figured a simple male pleopod 1 on a male from Darwin,
Australia
; pleopod 1 is absent in the smallest male and minute in the larger ones from this collection. Most of the specimens at hand have a minute anterior tooth on pleonal pleura 2–5.
Sakai (2011)
himself discussed variation in this character and in the presence or absence of the male pleopod 1 after presenting an extensive diagnosis.
