| K. Kumar et al. 2021 | Strophodus jaisalmerensis sp. nov. from Jaisalmer is distinguished from S. magnus (Agassiz 1838) by lack of a crest on its anterior teeth, smaller lateral teeth (both mesio-distally and labio-lingually), lateral teeth with much thinner crown with nearly flat or only slightly domed occlusal surface in comparison to the second lateral teeth of S. magnus, and a reticulate ornamentation of posterior teeth in comparison to that in S. magnus consisting of anastomosing ridges. Differs from S. longidens (Agassiz 1838) in having mesio- distally less elongate lateral teeth. Distinguished from S. tenuis (Agassiz 1838) by less elongate lateral teeth, lack of a strong sig- moidally curved crest on lateral teeth, and lack of a relatively com- plex ornamentation consisting of strong ridges originating from the centre of the lateral and anterior teeth. Distinguished from S. smithwoodwardi (Peyer 1946) by its less arched second anteriors, thinner and narrower (relative to mesio-distal length) lateral tooth crowns, and in having low, gently sinuous lateral teeth (better seen in labial and lingual views). Differs from S. medius (Owen 1869) in lacking an occlusal crest on anterior and lateral teeth, and in having a nearly flat occlusal surface in contrast to strongly arched and centrally domed lateral teeth. Differs from S. reticulatus (Agassiz 1838) in having mesio-distally less elongate and thinner lateral tooth crown, in lacking a domed area in the centre of lateral teeth, and in the absence of an occlusal crest and a strong, complex ornamen-tation consisting of radiating ridges from the centre. Differs from S. subreticulatus (Agassiz 1838) in having somewhat elliptical as opposed to a triangular occlusal outline of anterior/antero-lateral teeth. Differentiated from ?S. udulfensis (Leuzinger et al. 2017) in lacking a crest on the anterior and lateral teeth, in the absence of a rich ornamentation of curved ridges spreading from the apex, and in its nearly flat occlusal surface of lateral teeth unlike the mesially domed lateral teeth of (?) S. udulfensis. (?) S. dunaii (Szabó and Főzy 2020) is easily differentiated from the new species by its rich ornamentation consisting of frequently branching ridges, a low and wide transversal ridge running along entire crown surface close to the labial edge, and mesio-distally much longer lateral teeth with flattened distal and labial crown edges. S. tridentinus (Zittel 1870), differs from the Jaisalmer species by a labially oriented occlusal crest giving rise to a complex system of diverging ridges on lateral teeth. |
