Rhenopteridae is a family of the suborder Stylonurina from the order of the sea scorpions (Eurypterida) and the only family of the superfamily Rhenopteroidea .

features

In the species from the Rhenopteridae family, the rear edge of the metastoma was rounded. The prosomal limbs II to IV had short, firm spines, with only one being present on III. The prosomal members V and VI had no spines. The telson was short.

Locations

Representatives of the Rhenopteridae family have been found in Germany , Norway , Scotland and Wales .

Systematics

The superfamily and family were set up in 1951 by Leif Størmer . According to Lamsdell, Braddy & Tetlie 2010, it includes the following genera:

Subfamily Rhenopterinae
- Alkenopterus
- Rhenopterus
Brachyopterus
Kiaeropterus
Brachyopterella

More recent synonyms of the superfamily Rhenopteroidea are Brachyopterellidae Tollerton, 1989 and Alkenopteridae Poschmann & Tetlie, 2004.
