Type material.
Shoemaker (1945)
described his species form
six specimens
collected near
Bermuda
at depths between 700 and 1000 fathoms.
The
USNM has
three syntypes
;
two males
(109467 & 9)
and
one female
(109468).
The
whereabouts of the other
three specimens
is unknown.
Material examined.
Types
.
Syntype
female (
USNM 109468
) and
two syntype males
(
USNM 109467
& 9) from the
North Atlantic
, near
Bermuda
[
32º12’N
64º36’W
];
William Beebe Oceanographic Expedition
,
13 Jul. 1929
and 7 &
29 Sept. 1930
respectively: in spirit
.
Other material examined. Central South Pacific

Female

];

177º01’E
];
Dana
Stn.

.
Diagnosis.
Like typical form except for the following. Length of sexually mature specimens
12–16 mm
. Antennae 2 are relatively shorter, often subequal in length to A1. Gnathopoda and P3 & 4 have more robust articles. Gnathopod 1; basis especially broad with distinct anterior bulge. Pereopods 3 & 4 with shorter and wider merus, also propodus is shorter than carpus. Pereopods 5 & 6 are relatively longer. Pereopods 6 & 7 with relatively longer propodus.
Remarks.
Described as a species distinct from
L. clausi
by
Shoemaker (1945)
, the above differences are sometimes intermediate between
L. clausi
and
L. pirloti
. Thus, I concur with
Vinogradov
et al
. (1982)
in that
L. pirloti
should be considered a subspecies of the highly variable
L. clausi
.
Distribution.
This subspecies has been recorded from the North Atlantic, near
Bermuda
[
32º12’N
54º36’W
] by
Shoemaker (1945)
; the North-west Pacific, south of
Japan
by
Vinogradov (1960a)
and from the South
China
Sea by
Shih and Chen (1995)
and the Indian Ocean [
01º59.1’S
86º41.4’E
and
26º45.7’S
108º18.6É
] by
Vinogradov (1964)
. The
Dana
specimens are the first records from the central South Pacific.
