Rhenopterinae is a subfamily of the suborder Stylonurina from the order of the sea scorpions (Eurypterida).

features

In the species from the subfamily Rhenopterinae, the rear edge of the metastoma was rounded. The prosomal limbs II and III had a short, fixed spines, with only one was present at III. The prosomal limbs IV to VI had no spines. The post abdomen was caudal and the telson short.

Locations

Representatives of the subfamily Rhenopterinae were found in Germany ( Alken , Weinsheim , Overath and in the Westerwald ).

The subfamily Rhenopterinae was established in 1951 by Leif Størmer . According to Lamsdell, Braddy & Tetlie 2010, it includes the following genera:
