Taxonomy

Henry Augustus Pilsbry described this species under name Blanfordia integra in 1924.[1]

Davis (1979)[3] noted that genital structures of Blanfordia integra are similar to those of Fukuia.[2] Although he doubted if Fukuia and Blanfordia are morphologically distinct based on such evidence, it is an apparent confusion resulting from the inadequate generic assignment of Blanfordia integra.[2]

According to the molecular analyses of 18S ribosomal RNA, 28S ribosomal RNA, 16S ribosomal RNA, and cytochrome-c oxidase I (COI) genes by Kameda & Kato (2011)[2] noted that Blanfordia integra is undoubtedly a member of the genus Fukuia.[2]

Distribution

This species is endemic to Japan.[2] It is a Vulnerable species.[4]

The type locality is Makuragisan, Izumo, Honshu.[5]

Description

The shape of the shell is broadly ovate.[5] The shell has 4.5-5.3 whorls.[5] There is a strong axial sculpture on the shell.[5]

The width of the shell is 2.4-3.2 mm.[5] The height of the shell is 3.6-5.2 mm.[5]

Ecology

This species lives as a terrestrial snail in inland forests.[2] It is often arboreal.[2]

gollark: If they simply did not awful zoning, land would probably be substantially cheaper (via higher density in places).
gollark: In California apparently the problem is just accursedly awful zoning.
gollark: That seems like one of those really bad hacky patches.
gollark: Anyway, one interesting proposal I've read a lot is land value tax; you can set up the incentives such that you're basically just renting land from everyone, instead of buying and trading it, which seems more reasonable to me.
gollark: That doesn't seem like a very clear allocation mechanism.
