Material examined.

Lectotype of Streptaxis discus Pfeiffer, 1853 NHMUK 20130684. Lectotype of Streptaxis paradiscus Möllendorff, 1900 SMF 108534 and paralectotypes SMF 108535 (5 shells).

Remarks.

Discartemon discus has been recently re-described from the shell, genitalia and radula, and type specimens were re-investigated and illustrated (see Siriboon et al. 2014a).

All previous records of this species were all from “Annam” ( Siriboon et al. 2014a). This term is a historical political division during the colonial period, with an uncertain boundary. The distribution of Discartemon discus (= Discartemon paradiscus ) in Laos was reported by Schileyko (2000: 784, 2011: 23). However, no specimens were found by the present study and the records from Laos remain to be confirmed.
