[=Poropeltis Duncan, 1889, p. 46 (objective)]

Diagnostic Features	Apical disc large with smooth plates; pits present along plate sutures. Periproct small and diamond-shaped; generally smaller than suranal plate. Ambulacral zones narrow with one primary tubercle to every two pore-pairs; no perradial granulation. No sphaeridial pits in ambulacral zones. Interambulacral tubercles imperforate and non-crenulate.
Distribution	Late Jurassic (Oxfordian) of Switzerland and Germany.
Name gender	neuter
Type	Poropeltaris sculptopunctata Quenstedt, 1875, by monotypy.
Species Included	Only the type species.
Classification and/or Status	Salenioida; Saleniidae; Hyposaleniinae. Monotypic.
Remarks	Distinguished from other Hyposaleniinae by its non-crenulate tubercles. However, all individuals are small and no material has been examined, so the validity of this taxon is uncertain. It may turn out to be no more than a synonym of Hyposalenia. Quenstedt, F. A. 1872-1875. Petrefactenkunde Deutschlands . 1 Abt., 3. Echinodermen (Echinoiden), 719 pp., 28 pls. Fues's Verlag, Leipzig.
