Pleon and uropods
Somites with narrow subtriangular pleurites, with a rounded bulge on their basis.
Cephalic appendages
Last segment of antennular peduncles (basipodite) articulated with two flagella, flagella made of numerous and short cylindrical articles; antennas made of numerous and short cylindrical articles.
Thoracic appendages
Elongated Mxp3, made of cylindrical spineless segments; chelate P1; P1 propodus short, as long as wide; narrow, inflated dactylar bulge; short, wide P1 fingers, straight dorsally, slightly curved downward, equal in length; occlusal margin without teeth; P1 carpus short, subtriangular; elongated P1 merus, with a short process at outer side of its ventral extremity; P2-P3 chelate.
Ornamentation
Carapace densely covered by rounded tubercles, smaller in ventral part of branchial region and in pterygostomial region; intercalated plate covered by tubercles; row of tubercles parallel to the intercalated plate in gastric region; oblique row of tubercles ended by an orbital spine in gastric region; antennal row of coarse tubercles; tergites of pleonal somites covered by small rounded depressions, mainly on their posterior part; pleurites of pleonal somites covered by small depressions; P1 propodus densely covered by coarse tubercles organised in longitudinal rows on both ventral and dorsal surfaces; P1 fingers covered by rounded depressions; P1 carpus covered by coarse tubercles; P1 merus covered by small tubercles on dorsal margin, and with a row of spines along the extern ventral margin; smooth P2-P5.
DISCUSSION
Because the species was described from a single isolated P1 chela from the Kimmeridgian of Nusplingen (
Germany
),
Pustulina suevica
was recognized as an erymoid lobster only recently. Indeed,
Schweigert
et al.
(2000)
pointed out the strong similiraties between the
holotype
of
P. suevica
and the P1 chelae of the
holotypes
of
Eryma fraasi
Oppel, 1861
(
Fig. 13B
) and
Palaeastacus solitarius
Oppel, 1862
(
Fig. 13C
), from the same locality. These species share a subrectangular P1 propodus bearing wide and short fingers, ornamented by longitudinal rows of coarse tubercles. Considering these elements,
Schweigert
et al.
(2000)
concluded that
E. fraasi
and
P. solitarius
are junior synonyms of
P. suevica
. Moreover, the carapace of
E. fraasi
is mostly preserved. This allowed
Schweigert
et al.
(2000)
to point out the similarities of the carapace groove pattern of
Pustulina
and
Phlyctisoma
Bell, 1863
. So,
Phlyctisoma
became a junior synonym of
Pustulina
, and we concur with the conclusions of
Schweigert
et al.
(2000)
.
Étallon (1861)
described
Enoploclytia perroni
from the Oxfordian of Frasne (
France
;
Fig. 13
D-E). In the literature, this species was assigned to
Eryma
(
Oppel 1861
,
1862
;
Woodward 1900
;
Whiteaves 1903
;
Beurlen 1928
;
Mertin 1941
;
Charbonnier
et al.
2012b
),
Phlyctisoma
(
Förster 1965
;
Förster 1966
;
Taylor 1979
) or
Pustulina
(
Schweitzer
et al.
2010
)
. Examination of the
syntype
of
E. perroni
shows a carapace groove pattern and P1 chela typical of
Pustulina
: the elongated gastro-orbital groove with two divergent branches, the concave hepatic groove, the inflected postcervical groove joined to the posterior extremity of the hepatic groove, the presence of the cardiac groove, the short and subrectangular propodus with its short and wide fingers. The ornamentation of
E. perroni
made of coarse rounded tubercles, becoming smaller ventrally, is also identical to that of
P. suevica
. So, we consider
E. perroni
as another junior synonym of
P. suevica
. For the same reasons than
E. perroni
,
Eryma pseudobabeaui
Dollfus, 1863
(Kimmeridgian, Le Havre,
France
;
Fig. 13H, I
),
Enoploclytia edwardsi
,
Sauvage, 1891
(Kimmeridgian, Boulogne-sur-Mer,
France
;
Fig. 13J, K
) and
Enoploclytia dorsetensis
Woods, 1930
(Oxfordian, Weymouth,
United Kingdom
;
Fig. 13F, G
) are considered as junior synonyms of
P. suevica
. We noticed that
E. edwardsi
has already been considered as a synonym of
Phlyctisoma pseudobabeaui
and
E. dorsetensis
as a synonym of
P. perroni
by
Förster (1966)
.
Among the crustacean faunas of the Oxfordian-Kimmeridgian,
Pustulina suevica
is a typical species with a wide distribution in Western Europe. Fossils of this species are reported from many localities in
France
,
Germany
and
United Kingdom
. Moreover, it is the only erymoid species from the lithographic limestones of southern
Germany
to have been reported out of this country.
P. suevica
is distinct from some other species of the genus by its ornamentation. Indeed, there are no depressions as in
P. calloviensis
(
Förster, 1966
)
and
P. elegans
(
Förster, 1966
)
, the tubercles of
P. suevica
are coarser than those of
P. trisulcata
(
Schweitzer & Feldmann, 2001
)
, there are no small tubercles between the coarse ones as in
P. tuberculata
(
Bell, 1863
)
, and there is a strong antennal row in
P. suevica
contrary to
P. calloviensis
,
P. cretacea
(
Roger, 1946
)
,
P. elegans
,
P. minuta
, and
Pustulina victori
Devillez, Charbonnier, Hyžný & Leroy, 2016
.
Pustulina suevica
is also the only species with
P. elegans
to have an oblique orbital row. Like
P. minuta
, the cervical groove of
P. suevica
is almost straight contrary to
P. calloviensis
,
P. colossea
Devillez, Charbonnier, Hyžný & Leroy, 2016
,
P. elegans
, and
P. occitana
Devillez, Charbonnier, Hyžný & Leroy, 2016
. The gastro-orbital groove is also sub-horizontal while that of
P. calloviensis
,
P. colossea
,
P. elegans
,
P. occitana
,
P. spinulata
(
Secrétan, 1964
)
, and
P. tuberculata
is oblique. Moreover, the P1 fingers of
P. suevica
are sometimes ended by a hook contrary to
P. minuta
and
P. tuberculata
. Finally, the pleurites of the pleon are narrower than that of
P. minuta
and
P. trisulcata
.
