DIAGNOSIS: Carapace wider than long, anterior margin weakly toothed. Rostrum produced and rounded. Distal peduncular segment flattened, ovate. Antennular dorsal flagellum with 56–67 articles, ventral flagellum with two articles. Antennal segment I unarmed; flagellum with six to eight articles. Maxilliped II exopod without flagellum. Maxilliped III exopod without flagellum. Abdominal somite V pleura well calcified. Males with pleopods. Telson of male diamondshaped, evenly but weakly calcified.

TYPE
SPECIES:
Lepidopa myops
Stimpson, 1860
, as the senior synonym of
L. panamaensis
Efford, 1971
, the
type
species by monotypy.
INCLUDED SPECIES:
P. myops
(
Stimpson, 1860
)
;
P. distincta
(
Gomes Côrrea, 1968
)
.
REMARKS:
Calado (1995)
first introduced this generic name in her doctoral dissertation, but it must be considered unpublished from that source. It is unfortunate that she chose to subsequently publish the name in an abstract (
Calado, 1996
), but it is validly pub lished therein. A more complete redescription of the genus was given by
Calado (1997b)
.
This genus was described with the
type
and sole species of
Lepidopa panamaensis
(
Calado, 1996
)
. Direct comparison of the
type
specimens of that taxon and numerous specimens of
L. myops
showed no important differences, and the two taxa are synonymous.
Lepidopa myops
is therefore the
type
of
Paraleucolepidopa
as the senior synonym of
L. panamaensis
. To complicate matters further, none of
Calado’s (1996
;
1997b
) defining characters for the genus
Paraleucolepidopa
are diagnostic for that taxon, which suggests that
Paraleucolepidopa
may be a synonym of
Lepidopa
. However, a cladistic phylogenetic analysis of the
Albuneidae
(Boyko and Harvey, in prep.) shows that the monophyletic clade containing
L. myops
and
L. distincta
is the sister taxon to
Lepidopa
and contains several synapomorphies (antennular dorsal flagellum with 56–67 articles, antennal segment I unarmed, maxilliped II exopod without flagellum, abdominal somite V pleura well calcified). As
Calado’s (1996)
name is the earliest available for this clade, the name
Paraleucolepidopa
must stand but based on an entirely different suite of characters than that given by
Calado (1996
,
1997b
).
This genus is intermediate between
Leucolepidopa
and
Lepidopa
.
