There is very little known about this species, I’m not even sure if it’s currently believed to exist. It is known only from a handful of males collected and preserved in the early 1900s. The claw like endite of the 1st thoracic appendage argues strongly that it is/was a distinct species.
33, 8 apodous
49 – 52
Carapace more rounded than typical in Lepidurus, endite 6 of the first thoracic appendage is developed into a claw like structure (it is reduced to a small lobe in all other notostracans), second maxilla present
