Munidopsis longimanus
(
A. Milne-Edwards, 1880
)
Munidopsis longimanus
has been reported as
Elasmonotus longimanus
and
Munidopsis longimana
(see
Baba
et al.
2008
) from the Gulf of
Mexico
to
Colombia
in depths of
292 to 1281 m
(
Chace 1942
;
Navas
et al.
2003
). The specimens used in this analysis were from the Caribbean and the Gulf of
Mexico
in depths of
360 to 1066 m
. Thirty-four males (CW from
4.2 to 8.9 mm
), six non-ovigerous females (CW from
3.8 to 8.4 mm
), and 13 ovigerous females were measured (CW from 5.0 to 9.0 mm). Non-ovigerous females and females were not significantly different in size (t-test, df
=
17, t
=
0.541, p
=
0.596); the sizes of males and females were not significantly different (t-test, df
=
51, t
=
-1.111, p
=
0.272). Females had between one and
62 eggs
, and the average egg diameter ranged from
0.87 to 1.24 mm
. Fecundity was significantly correlated with CW (R2
=
0.705, p
=
0.005) (
Fig. 10
D); the average egg diameter was not correlated with CW (R2
=
0. 0 483, p
=
0.601). Specimens were collected in all months except February and March; ovigerous specimens were found in every month but February, March, June, September, and October (
