Geographic Coverage

We examined 98 specimens, 17 occurrences from nine localities.

Bounding Coordinates South West [34.44, 135.55], North East [36.85, 140.73]
Sampling Methods

The authors manually explored the museum's collections from the relevant range with the help of the curator, as the Iwakawa's collection was not fully organized.

Study Extent Our investigation was conducted on Viviparus sclateri in the Iwakawa's collection preserved in the National Museum of Nature and Science, Tokyo.

Method step description:

  1. The locality information of specimens was obtained from the labels with the specimens. The Iwakawa's list (Iwakawa, 1919) was also consulted when necessary.
  2. Each specimen was examined and re-identified by the author based on the diagnostic characteristics. In particular, the original descriptions of Japanese viviparid species and following references provided principal criteria for comparison and identification: Annandale (1921), Okada and Kurasawa 1950, Habe 1973, Masuda and Uchiyama (2004), Kihira et al. (2009), Hirano et al. (2015), Hirano et al. (2019a) and Hirano et al. (2019b).
