Conservation status.

This study reveals that Angustopila huoyani inhabits two caves that are geographically far from each other. The typical threats to such habitats is quarrying and human disturbance through tourism.

Remarks.

Angustopila huoyani has been described from a single cave in northeastern Hunan Province. Nearly identical shells have been found in another cave in northern Guangxi Province, which is situated ca. 500 km south from the type locality. The only difference is that the new shells have some very faint spiral striae on the teleoconch, which were not detected in the original population. This difference is, however, insufficient to distinguish these two populations on either specific or subspecific level. Therefore, we refer to the population collected in Guangxi as a disjunct population of Angustopila huoyani . This finding underscores the need to explore more cave systems in order to make inferences about subterranean biodiversity in China, and specifically here for the distribution of minute troglobitic land snails.
