Hyidae Chamberlin, 1930


The family Hyidae were first recognized by Chamberlin (1930) who included the sole genus Hya with the type species from the Philippines. Beier (1932) transferred the group to the Ideoroncidae, and relegated it to subfamily status. Chamberlin (1946) added the Leucohyinae to the family, but this group was transferred to the Bochicidae by Muchmore (1982, 1998). Two genera treated by Beier as members of the Hyidae, Parahya and Stenohya, were transferred to other neobisioid families by Harvey (1991, 1992).

The family was revised by Harvey (1993) who recognized three genera, Hya in Hyinae, and Indohya and Hyella in Indohyinae. Harvey and Volschenk (2007a) synonymised Hyella with Indohya, and disbanded the subfamilial system.

Hyids are restricted to the Old World, with Hya found in south-east Asia and Sri Lanka, and Indohya in India, north-western Australia and Madagascar. They occur in leaf litter or in caves.
