Comments.
Diplosynapsis spina
sp. nov.
seems to be the same species drawn by
Artigas & Papavero (1997)
and treated as
Diplosynapsis
sp. However, the material from those authors was not available for this study. Furthermore,
Artigas & Papavero (1997)
did not indicate where the specimen that they studied was collected.
