Abstract:

The endophallus of the genus Zaitzeviaria is characterized by membranous sac with several bladders covered by spines. The endophallic structures of most members are observed in detail and their homologies are examined. Five Japanese members of the genus including a new species are reviewed: Z. sotai sp. nov., Z. ovata (Nomura), Z. brevis (Nomura), Z. gotoi (Nomura) and Z. kuriharai Kamite, Ogata et M. Satô. Zaitzeviaria sotai sp. nov. is collected from Shimane and Tottori Prefectures including Oki Islands.
