Type material.
Shoemaker (1945)
described this
variety from
eight specimens
collected near
Bermuda
, at depths between 600 and 1000 fathoms. He states that “the length of the type female is
29 mm
”. The USNM has
three female
specimens, the type (109450) and
two paratypes
(109451 & 2). The whereabouts of the other
five specimens
is unknown
.
Material examined.
Types

Diagnosis.
Like typical form except for the following. Length of sexually mature females
27–30 mm
. Pereopod 6 is relatively longer with propodus expanded distally into rounded club-shape, housing retractile dactylus. Pereopod 7 is slightly shorter than half-length P6.
Remarks.
Described as a mere variety of
L. loveni
by
Shoemaker (1945)
it was elevated to sub-specific rank by
Vinogradov
et al
. (1982)
and according to them the features characteristic of
L. loveni grossipes
are only exhibited by sexually mature females.
Distribution.
This subspecies has been recorded from the North Atlantic, near
Bermuda
[
32º12’N
52º36’W
] by
Shoemaker (1945)
; the North–west Pacific, S.E. of
Japan
[
30º52’N
153º16’E
&
30º53’N
153º09’E
] by
Vinogradov (1957
&
1960a
) and N.E. of Marshall Is [
16º08’N
173º10’E
] by
Vinogradov (1960a)
. The SAMA specimen (
Fig. 1
) is the first record from the North-east Pacific.
