A new online paper (I can't determine yet if the new species is named
in the paper):

The second pterosaur genus to be established, Rhamphorhynchus von
Meyer, 1847, has historically been used as a wastebasket material.
Several species have been erected for fossils found in Europe and
Africa, the majority of which are based on non-diagnostic material.
Following Bennett's (1996) review of its taxonomy, Rhamphorhynchus is
generally regarded as a monospecific taxon restricted to the Late
Kimmeridgian and Tithonian of Southern Germany. Here we describe a
disarticulated but complete right pterosaur wing, MJML K-1597 from the
Kimmeridge Clay Formation of England. Based on a combination of
morphology and statistical analysis, MJML K-1597 can safely be
referred to Rhamphorhynchus, making it the first diagnostic
Rhamphorhynchus specimen from outside of Germany. Furthermore, based
on the unique length ratio between wing phalanx 1 and wing phalanx 2,
MJML K-1597 can be referred to a new species of Rhamphorhynchus.
