[3] In 2020, Borja Holgado and Rodrigo Pêgas named a new species of Uktenadactylus, U. rodriguesae after Rodrigues, known from a snout fragment (cataloged as IWCMS 2014.82) found on the Isle of Wight.

[4] The holotype and only specimen of U. wadleighi, the partial snout, has a length of about fifteen centimetres and consists of the front end of the skull, containing the premaxilla and a small part of the maxilla.

However, it differs from U. wadleighi in that the depression is shallower, the second pair of teeth projects more laterally, and the margins of the deltoid facet (an upturned region of the front palate) are concave as opposed to straight.

Differences between the taxa include the more forward position of the crest with C. clavirostris, beginning at the very tip of the snout; a deeper palatal groove and shallow grooves running parallel to the ridge of the front part of the palate; a depression located below the first alveoli and a more lateral position of the second, third and fourth tooth pairs whereas the fifth and sixth pair are to the contrary much closer to the midline of the skull.

Both forms share some derived traits with Siroccopteryx: the second and third teeth pairs are larger than the fourth; the tip of the snout is flat causing the "prey grab" to be rectangular in cross-section and a similar thickness of the crest.

[6] In 2019, a slightly different topology by Jacobs et al. also recovered Uktenadactylus within the Ornithocheiridae, but as the sister taxon of several Coloborhynchus species, and identified with its current name.

[8][9][10] The cladogram on the right is a topology based on the phylogenetic analysis made by Borja Holgado and Rodrigo Pêgas in 2020, where they recovered Uktenadactylus as the sister taxon of Nicorhynchus within the Coloborhynchinae.
