Type species.

Streptaxis discus Pfeiffer, 1853, by subsequent designation by Ancey (1884: 399).

Diagnosis.

Shell flattened to globose-heliciform. Last whorl rounded to angular, less distorted, and often with peripheral keel; whorls regularly to rapidly expanded. Apertural dentition varied, ranging from only one parietal lamella to additional dentition: upper palatal, palatal, basal, columellar and supracolumellar lamellae. Genitalia with short to long penis, sometimes with penial appendix and penial sheath covering entire penis length. Penial hooks present and vaginal hook absent.

Remarks.

This genus was recently revised in both shell and genital diagnostic characters, and the intrageneric relationship was discussed ( Siriboon et al. 2014a, 2020). At present, the genus Discartemon comprises thirty recognized species, including a new species described herein ( Sutcharit et al. 2020).
