REMARKS
The studied specimens look similar to
Baschkirina ballei
Crasquin, 2010
from latest Permian of Meishan section, South
China
(
Crasquin
et al.
2010a: 358
, figs 23R-W).
Baschkirina ballei
have longer PDB and less compressed AB.

REMARKS
Our specimens are similar to
B. huzhouensis
Forel, 2010
from the latest Permian of Meishan section, South
China
(
Crasquin
et al.
2010a: 359
, fig. 23E-H) in having long carapace with straight DB and PDB. However, AB of
B.
cf.
huzhouensis
is less compressed and located above mid H, but AB is located at mid H in our specimens.
