Body length -
females: 2.55-2.84mm (4 specimens)
Female. Body elongated. Prosome 2.3 times
longer than wide. Postero-Iateral corners of
last thoracic somite ending in slender processes. Proportional lengths of prosome and
urosome 55 : 45; proportional lengths of
urosomites and furca 11: 27: 17: 16: 16: 13 =
100. Posterior margins of urosomites with
notched hyaline fringe. Maxilliped basal
segment with one inner denticle; second
segment with four denticles on inner surface· ,
Order POECILOSTOMATOIDA
Family Oncaeidae
third segment very short and unarmed· ter.
'
mmal segment clawshaped with distal row of
small denticles on concave margin and small
spinule at end of row. Re3 of P1-P4 with two
spines on external margin. P5 with two setae
of different length; longer seta Bot reaching
posterior margin of genital complex.
Distribution
L. aculeata has been reported from all oceans
including the Mediterranean Sea. This species
has a tropical distribution, although a few
specimens have been collected outside of
these waters (Heron and Damkaer 1978). It
has been reported also for the Antarctic
(Ramirez and Dinofrio 1976) and in Argentine
(Ramirez 1969) and Chilean (Wilson 1942)
waters. In the present study, the species was
sporadically present from 100-500m at two
stations in the Pacific area of the Straits of
Magellan.
