Diagnosis
: Rostrum slender, armed on the upper margin, no extending beyond of scaphocerite tip. Rostrum with 6–8 teeth on upper margin and 5–6 teeth in ventral margin. Somites 2–6 with dorsal carina. Abdominal Somite 3 with pronounced spine reaching half of fourth somite. Fourth and fifth abdominal somites not ending on a dorsal terminal tooth. Sixth abdominal somite ending on strong dorsal terminal tooth. Telson with 5–6 (usually 6) dorsolateral spines (modified from
Spence Bate 1888
).

Spence Bate, 1888
. A. Male, lateral view. B. Telson, dorsal view. C. Abdominal somites 1–5 in dorsal view (MOUFPE: 18.461). Scale bar = 1 cm.
Distribution
: Eastern Atlantic: Senegal (Kayar Canyon), Sierra Leone, Gabon, Congo, Angola, Mid Atlantic Ridge.
Southwestern Atlantic
:
Brazil
(
Ceará
Chain (Seamounts)
,
Rocas Atoll
and
Fernando de Noronha
) (
Spence Bate 1888
;
Holthuis 1951
;
Crosnier & Forest 1973
) (
Fig. 8
).
Bathymetric distribution
:
200–4575 m
depth (
Spence Bate, 1888
;
Balss 1925
;
Kemp 1939
;
Holthuis 1951
;
Crosnier & Forest 1973
), herein this species was found in Rocas Atoll between
65–984 m
depth, thus extending its bathymetric distribution to shallower waters.
Remarks
: The specimens analyzed herein do not differ from the description by
Spence Bate (1888)
,
Kemp (1906)
and
Crosnier & Forest (1973)
.
Acanthephyra kingsleyi
belongs to
A. purpurea
A.
Milne-Edwards, 1881
group (
Kemp 1939
), which includes seven species closely related. Characters of rostrum shape and dentition are of minor taxonomic importance in this group (
Cardoso, 2013
).
Acanthephyra kingsleyi
is characterized by the fourth and fifth abdominal somites without dorsal spine (
Fig. 7
A–C) and telson with 5–6 dorsolateral teeth (
Fig. 7B
), while
A
.
purpurea
has the fifth abdominal somite with a strong dorsal spine and telson with 4–5 dorsolateral spines (Zariquiey Alvarez 1968;
Crosnier & Forest 1973
). Regarding the geographical distribution of these two closest species is:
A
.
kingsleyi
was previously known only from Eastern Atlantic in bathypelagic zones (
Fig. 8
) and
A
.
purpurea
has an amphi-Atlantic distribution. In this paper,
A
.
kingsleyi
is recorded by first time in Southwestern Atlantic (Brazilian waters), with first records from
Ceará
Chain (Seamounts), Rocas Atoll and Fernando de Noronha archipelago, located in Northeastern
Brazil
