Plectopylidae is a taxonomic family of large air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Plectopyloidea.

[1][2] The range of the family Plectopylidae (Plectopylis Benson 1860 s. l.) extends from Nepal and Northeastern India through large part of Southeastern Asia (including the Malay Peninsula, Northern Thailand, Northern Vietnam, Central and Southern China) to Taiwan and Southern Japan.

Up to now, the distribution of Plectopylidae is divided into two geographic regions: (1) Nepal, Northeastern India (Assam and Arunachal Pradesh), Myanmar, western Yunnan, western part of Thailand, Northern Malaysia and northwestern part of Laos, and (2) Northern Vietnam, Southern China (west of the Eastern Yunnan–Guizhou–Middle Sichuan line), Taiwan and the Ryukyu Islands.

[7] Living specimens occur at the base of large limestone rocks surrounded by leaf litter and humus.

[7] Most living species have reticulated sculpture on the dorsal shell side, which is often covered with soil and this may be of value in providing camouflage.
