A B S T R A C T
A new species, Carpoapseudes prospectnes, is described from the South
Atlantic off Brazil. This is rhe firsr record of this genus from depths above
800 m. The systematic position of the genus is discussed. Carpoapseudes pros
pectnes n. sp. shares many characters with C curticarpus Bacescu, 1982, but
can be distinguished from this and ail other species in the genus by the pré
sence of an anteriorly directed spine on the basis of pereopod 1 and 2 and by
the length of carpus and merus being subequal.

Une nouvelle espèce du genre Carpoapseudes Lang de l'Atlantique sud-occiden
tal (Crustacea, Tanaidacea).
Une nouvelle espèce, Carpoapseudes prospectnes, est décrite de l'océan
Atlantique au large du Brésil. C'est la première fois qu'une espèce de ce genre
est recensée au-dessus de 800 m de profondeur. La position systématique du
genre Carpoapseudes est abordée. Carpoapseudes prospectnes n. sp. présente
plusieurs caractères en commun avec Carpoapseudes curticarpus Bacescu,
1982. La nouvelle espèce se distingue de C. curticarpus, ainsi que des autres
espèces du genre, par la présence, sur le basis des péréiopodes 1 et 2, d'une
épine orientée vers sa partie distale ainsi que par la longueur du carpus simi
laire à celle du mérus.

T h e phy logeny o f the A p s e u d o m o r p h a needs
r e v i s i o n s a n d the re is m u c h c o n f u s i o n a n d
c o n t r a d i c t i o n in the fami ly level sys t ema t i c s
(Lang 1 9 6 8 ; G u t u 1 9 7 2 ; Gard iner 1 9 7 3 ; Sieg
1980; Gu tu 1 9 8 1 , Sieg 1984, 1986) . T h e validi-
ty and systematic position o f subfamilies within
the Apseudidae Leach, 1814 and Whitelegiidae
Gutu , 1972 , has also been subject to controversy
(Kudinova-Pas te rnak 1 9 6 6 ; L a n g 1 9 6 8 ; G u t u
1972; 1980; Lang 1973; Sieg 1986; Gu tu 1996a,
1996b) . Sieg (1986) placed Carpoapseudes Lang,
1968 , in the family Whitelegiidae using the leaf-
shaped caudo-distal spine (setae) o f the maxilli
ped endite as diagnostic character o f the family.
G u t u ( 1 9 7 2 , 1 9 8 0 , 1 9 9 6 a , 1 9 9 6 b ) , however,
considered Carpoapseudes to be in a subfamily,
the L e v i a p s e u d i n a e S i e g , 1 9 8 3 , w i t h i n the
Apseudidae. G u t u (1996a) considered the spini-
form process o f the coxa o f pereopod 1 (pereo
p o d 2 acco rd ing to the t e rmino logy o f G u t u
1972) particularly important. I agrée with Gu tu
(1996a) that the shape o f the caudo-distal maxil
liped setae is not enough to be the only diagnos
tic character o f a family. N o other characters
combine the gênera o f Whitelegi idae with the
gênera o f Leviapseudinae on the contrary. T h e
antennas are short and broad in Whitelegiidae,
long and slender in Leviapseudinae. T h e pleotel-
son are comparatively shorter in Whitelegiidae,
elongated in Leviapseudinae. Visual éléments are
p r é s e n t in W h i t e l e g i i d a e , a b s e n t in
Leviapseudinae . Hab i ta t préférences is shallow
water in Whi t e l eg i idae , deep water in Levia
pseud inae . T h e maxi l l iped pa lp is serrated in
Whitelegiidae, not in Leviapseudinae. Further-
more if one consider the amount o f specially sha-
ped setae within the Apseudomorpha , it is not
unreasonable to suggest that the leaf-shaped setae
of Leviapseudinae and Whitelegiidae, have evol-
ved independently. However, a revision o f the
apseudomorphan systematics is not within the
scope o f this work. T h e Leviapseudinae is here
placed within the Apseudidae but no phylogene-
tic analysis have been made to support this.
T h e diagnosis o f Carpoapseudes has recently been
modified (Gutu 1996c) in order to accommoda-
te the spec i e s C. curticarpus B a c e s c u , 1 9 8 2 ,
rather than erecting a new genus for this species.
Carpoapseudes curticarpus would otherwise have
to be excluded due to a short pereopod 1 carpus,
one o f the diagnostic character o f Carpoapseudes
is a long carpus relative to the merus (note that
the t e r m i n o l o g y o f S i eg 1 9 7 7 is used in this
work). Gu tu (1996c) reasoned that ail other cha
r a c t e r s o f C. curticarpus c o r r e s p o n d e d to
Carpoapseudes and that it was possible that other
species would be found in the future justifying
his action. Carpoapseudes prospectnes n. sp., des
cribed herein, seems to do just that, with a per
eopod 1 carpus subequal to merus.
Carpoapseudes is generally considered a deep-sea
genus with most species living at abyssal depth
(Lang 1 9 6 8 ; Bacescu 1 9 8 2 ; 1 9 8 5 ; Sieg 1 9 8 3 ) .
Only C. serratispinosus Lang, 1968, has previous-
ly been reported above 1000 m.
In the description o f Carpoapseudes prospectines
the body characteristics are from maie holotype
and appendages from female pararypes, unless
otherwise stated. T h e type material is deposited
in the Museu Nacional , Rio de Janeiro ( M N R J ) ,
