Remarks. –
This species was described from
Madagascar
(A.
Milne-Edwards, 1873
) and has been reported from various localities in the Indian Ocean (
Ward, 1942
;
Guinot, 1967a
;
Serène, 1984
) and in the Pacific Ocean (De
Man, 1902
;
Rathbun, 1906
; Edmonson, 1925;
Takeda, 1972
,
1976
; Ng & Clark, 2002). This species has been previously reported from the
Philippines
by Serène & Umali (1972), based on a single male collected from
Batangas
. It is interesting to note that all of the specimens reported in this paper, one of them ovigerous, are much smaller than this male specimen (carapace, 14.0 × 9.0 mm). Ng & Clark (2002) remarked on the differences in size at maturity of the specimens found in Hawaii,
Guam
,
New Caledonia
and the
Philippines
and suggested that
Paramedaeus simplex
may be a species complex. The present material also indicates that a revision of this species is clearly necessary.
