Fukuia integra, also known as Blanfordia integra, is a species of land snail which has an operculum, a terrestrial gastropod mollusk in the family Pomatiopsidae.
Taxonomy Henry Augustus Pilsbry described this species under name Blanfordia integra in 1924.
Davis (1979)Davis G. M. (1979). "The origin and evolution of the gastropod family Pomatiopsidae, with emphasis on the Mekong river Triculinae". Academy of natural Sciences of Philadelphia, Monograph 20: 1-120. at Google books. noted that genital structures of Blanfordia integra are similar to those of Fukuia. 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.
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) noted that Blanfordia integra is undoubtedly a member of the genus Fukuia.
Distribution This species is endemic to Japan.Kameda Y. & Kato M. (2011). "Terrestrial invasion of pomatiopsid gastropods in the heavy-snow region of the Japanese Archipelago". BMC Evolutionary Biology 11: 118. . It is a Vulnerable species. "ヤママメタニシ" . 日本のレッドデータ検索システム [Japanese Red List Data Book], accessed 17 July 2011.
The type locality is Makuragisan, Izumo, Honshu.Bartsch P. (1936). "Molluscan intermediate hosts of the Asiatic blood fluke, Schistosoma japonicum, and species confused with them". Smithsonian Miscellaneous Collections 95(5): 1-60.
Description The shape of the shell is broadly ovate. The shell has 4.5-5.3 whorls. There is a strong axial sculpture on the shell.
The width of the shell is 2.4-3.2 mm. The height of the shell is 3.6-5.2 mm.
Ecology This species lives as a terrestrial snail in inland forests. It is often arboreal.
