Rhamphorhynchus muensteri (Wellnhofer 1975) JME-SOS 4009, no. 62 in the Wellnhofer catalog, was a sister to R. muensteri and phylogenetically preceded R. gemmingi.

Distinct from R. muensteri the skull of no. 62 had a more robust temple and a more robust mandible. The deltopectoral crest was rounder. The ulna and radius were distinctly longer. The pes was distinctive with a longer metatarsal I, shorter medial digits and longer lateral digits. See R. longiceps for size comparisons.
