Taxonomy
editSwedish malacologist Carl Agardh Westerlund discovered and described this species under the name Physa sibirica in 1877.[1][2] Starobogatov et al. moved this species to the genus Sibirenauta in 1989.[2] Vinarski and colleagues designated the lectotype for Sibirenauta sibirica in 2013 and the lectotype is stored in the Swedish Museum of Natural History in Stockholm.[2] The generic name Sibirenauta is feminine (according to original description), the correct species name should be Sibirenauta sibirica instead of S. sibiricus as it was cited by several authors.[3]
Distribution
editDistribution of Sibirenauta sibirica include northern Asia and Alaska.[2] It occurs in Arctic Asia, Subarctic Asia and in the south of Eastern Siberia.[2]
This species occurs in:
- Wrangel Island, Russia.[4] No mollusc species were found on Wrangel Island up to 2015.[4]
The type locality is Yenisei River, Sopotchnaya Korga, 71°40’N in Taymyr Peninsula.[1][2]
Description
editThe external and internal morphology is described and depicted for example by Vinarski et al. 2015.[3][4]
The height of the shell is up to 13 mm, usually 10-12 [3] The shell has 6 whorls.[1]
Dimensions of the lectotype are as follows: The width of the shell is 4.7 mm.[2] The height of the shell is 8.8 mm.[2] The shell has 4.75 whorls.[2]
Ecology
editFor example, there was pH 8.2 and 84 ppm NaCl on the lake locality in the Wrangel Island.[4]
