GENUS REINIA KOBELT, 1876

(= CLADE F)

Type species: Balea variegata A. Adams, 1868

Synonyms: Parareinia Nordsieck, 1998 ; Pictophaedusa Azuma, 1982 ; Proreinia Thiele, 1931 ; Pseudophaedusa Tomiyama, 1984 .

Diagnosis: Shell small to very small, frequently thin-walled, frequently with subaxial and whitish flammulation, occasionally with a light-coloured band below the suture. Superior lamella frequently reduced to various degrees, occasionally developed. Inferior lamella usually developed, spirally ascending and approaching to the superior lamella. Plicae present except for R. variegata (A. Adams, 1868) . Principal plica usually developed, but occasionally shortened or reduced. Upper and lower palatal plicae usually present. Lunella always absent. Clausilium present except for R. variegata , wide. Diverticulum of bursa copulatrix frequently reduced to various degrees. Ecology arboreal. Reproduction ovoviviparous. Presence of unique deletions in the hyper variable region of ITS2 ( Fig. 5) is a molecular diagnostic character of the genus.

Morphology: Apex pointed. Plicae and clausilium located laterally if present. See also Diagnosis.
