Parasites
A branchial bopyrid is present on one of the specimens from Maribago. A bopyrid is also present beneath the abdomen of
one male
(iii). A couple of bopyrids are present beneath the abdomen of
one female
(v).
Remarks
Not previously recorded from the
Philippines
. Previously reported from Nouméa,
New Caledonia
, by
Monod (1976)
. The Dumaran Channel specimens were collected in association with
Palaemonella pottsi
and
Periclimenes affinis
. The Touho specimens were found with
Periclimenes amboinensis
.
The majority of specimens still have both second pereiopods attached. The chelae are subequal and similar, short and stout, about 1.2 times the carapace length, with a wellmarked ‘‘ball and socket’’ articulation with the similarly stout carpus. The distal cutting edges of the fingers are minutely serrate. The ambulatory dactyl of the third pereiopod is biunguiculate with a clearly demarkated unguis, the proximal dorsal aspect of which bears a strong central non-articulated spiniform tooth, flanked medially and laterally by smaller similar teeth, not always readily visible. The propod is sparsely setose and the spines are distally dentate as reported in
Bruce (1980a
,
1982
,
1996
).
Borradaile (1915
,
1917
) did not provide any illustrations with his description of the
type
material of this species. The second specimen discovered unfortunately lacked the second pereiopods (
Holthuis 1952a
).
Miyake and Fujino (1968)
, reporting on specimens from the
Palau
Islands, were the first to describe and illustrate the second pereiopods but they did not comment on the carpopropodal articulation.
Monod (1976)
described and illustrated a specimen from
New Caledonia
but did not provide information on the second pereiopods.
Bruce (1980a)
similarly omitted reference to these appendages in reporting on a juvenile associated with a holothurian host in the
Solomon Islands
. These descriptions also illustrate the ambulatory dactyls, but show or describe only a single simple dorsal spine and not a trifid spine as in the present specimens.
