Pachylister Lewis, 1904, 145 [type species: Hister caffer Erichson, 1834, 132. Original designation].
The Taiwanese Pachylister has been represented by three species, chinensis, lutarius and orientalis, but the latter two species were recorded by Lewis (1995) on the basis of Shirakis collection. Accordingly, the Lewis records are doubtful still now (Kurosawa, 1980). I recognize only one species, chinensis. Ohara (1999) gave a detailed redescription of chinensis. Herein I add some taxonomic notes with illustrations of female genitalia and SEM photos of several features.
