Type species
Paraostenia voultensis Secrétan, 1985 by monotypy.
Original diagnosis ( Secrétan 1985)
The voluminous and rounded eyes, the gills and the anterior and posterior appendages are as in Dollocaris . The form of the carapace is nearly identical to that of Ostenia View in CoL ( Arduini et al. 1980 amend Arduini & Brasca 1984) differing in form from Dollocaris in the outline which is proportionally higher and shorter and devoid of suborbital spine below the orbital opening which is less deep and more gaping.
Emended diagnosis
Thylacocephala with a symmetric optic notch, a sharp antero-dorsal corner, a dorsal carina, a concave posterior margin, rounded postero-dorsal and postero-ventral corners, long and gracile appendages.
