Neoctenogalumna
gen. nov.
Type
species:
Ctenogalumna moresonensis
Engelbrecht, 1972
Diagnosis.
Body elongate elliptic, pear-shaped; lamellar and sublamellar lines absent; shape of sensilli diverse (clavate, setiform, fusiform); anterior notogastral margin straight; 10 pairs of notogastral setae represented by alveoli or present; notogaster with four pairs of porose areas,
Aa
represented by one pair; median pore present; adanal lyrifissures located near to anal aperture; posterior porose area present or absent; leg tarsi with one or three claws.
Etymology.
The prefix
neo
is Greek meaning “new” and refers to the genus
Ctenogalumna
Balogh, 1960
.
Comparison.
Neoctenogalumna
sp. nov.
is very similar in body shape and form of anterior notogastral margin to
Leptogalumna
Balogh, 1960
(see Balogh, 1960
b
), but it differs from the letter by the absence of sublamellar lines on lateral side of prodorsum (versus present in
Leptogalumna
) this character is very important for the systematics of genera within the family
Galumnidae
.
Remarks.
Ctenogalumna
is a genus that was proposed by Balogh (1960
a
) with
Ctenogalumna madagascarensis
Balogh, 1960
as
type
species, indicating absence of the lines
L
and
S
as the main characters of the genus. However, Mahunka (1996) specified that the
type
species has been incorrectly described (sublamellar lines present versus absent in Balogh’s description) and should be placed in the genus
Allogalumna
. Hence, the genus
Ctenogalumna
was recognized as a junior synonym of
Allogalumna
(Mahunka 1996)
. However, Engelbrecht (1972
b
) and Starý (2005) have described new species of
Ctenogalumna
, which morphologically correspond to the initial generic diagnosis (Balogh 1960
a
) of
Ctenogalumna
(absence of the lines
L
and
S
), although species described by them have differences in body form and shape of anterior notogastral margin. Thus, we propose a new name and new
type
species for this genus
Neoctenogalumna
gen. nov.
with
Ctenogalumna moresonensis
Engelbrecht, 1972
as new
type
species.
