Type species.

Koreozospeum nodongense sp. n.

Diagnosis.

Shell thin, ovate-conic, fine spiral rows of interconnected pits constant throughout teleoconch, peristome oblique auriform, conspicuous plicate lip (side view).

Differential diagnosis.

Differs from Carychium by its squat ovate-conic form, absence of major apertural dentition and its singularly troglobitic ecology; from Zospeum by the oblong, slightly detached, oblique, auriform peristome, shallow suture, minimally convex whorls, interrupted low lamella on roof of interior penultimate whorl forming annular lamella, and the conspicuously pleated lip folded back onto the body whorl and not rolled into the body whorl as in Zospeum .

Derivatio nominis.

The name derives from Korea, the land of the type locality and the similarity to European Zospeum .

Distribution.

Only known from Nodong cave.
