Distribution
. Western Atlantic:
USA
(
North Carolina
), Gulf of Mexico, Caribbean Sea,
Venezuela
,
Brazil
(
Ceará
and
Rio Grande do Norte
– Potiguar Basin,
Pernambuco
,
Bahia
,
Espírito Santo
,
Rio de Janeiro
,
São Paulo
) (
Spence Bate, 1888
;
Komai, 2004a
;
Felder
et al
., 2009
; this study).
Bathymetric distribution
. The species has been recorded at depths of
443–1,760 m
(
Holthuis, 1971
;
Komai, 2004a
;
Felder
et al
., 2009
;
Vázquez-Bader and Gracia, 2013
). In the present study, the species was recorded between depths of
908–1,110 m
.
Remarks
. The examined specimens have the diagnostic characters of
G. aculeata
as described by
Smith (1882)
,
Holthuis (1971)
and
Komai (2004a)
.
Glyphocrangon aculeata
is easily recognized among the Atlantic species of the genus by the anterior fourth carina of the carapace forming a vertically compressed, acute lamina (wing-like spine).
Along the Brazilian coast,
G
.
aculeata
was first recorded by
Spence Bate (1888)
on the basis of material collected off Recife (state of
Pernambuco
), at a depth of
1,215 m
.
Komai (2004a)
extended its distribution to the states of
Bahia
and
Espírito Santo
, between
707–1,760 m
depth. The present record is the first from Potiguar Basin and fills a gap in the distribution of
G
.
aculeata
in the south Atlantic, suggesting that this species is much more widely distributed than currently assumed.
Females were more abundant and larger in size than compared to males (see
Tab.2
).
