Type species.

Systenostoma tamlod Panha & Burch, 2002, by original designation (Panha and Burch 2002a).

Remarks.

The genus was recently introduced to include the tiniest known land snails ( Páll-Gergely et al. 2022). Species of this genus are characterised by tiny, colourless shells (typically less than 1.2 mm), 0-5 apertural barriers, and typically 10-20 spiral striae on the body whorl. Currently, the genus comprises more than 50 species that are mainly distributed in mainland Indochina (Laos, Myanmar, Thailand and Vietnam), with a few species recorded from southern China and a single species from India ( Páll-Gergely et al. 2023). From Myanmar, two species are now recorded.
