Pterodactylus scolopaciceps  BSP 1937 I 18 (Broili 1938, P. kochi No. 21 of Wellnhofer 1970, 1991) was a sister taxon in which the lacrimal process of the jugal was very low. A vomer ridge was medial to the maxillary teeth. The dentarywas deeper. The teeth were fewer and relatively twice as large, as in No. 20. The ischium was rounder distally. The prepubis is strongly divided into a short anterior process and a very long ventral process, grealy deepening the torso.
