Abstract

Phymatodiscidaefam. nov. is diagnosed, with Phymatodiscus as the type genus. A new genus, Bardizongen. nov., with Bardizon eotvosisp. nov. (from Indonesia) as the type species, is erected to accommodate the Phymatodiscus species with an eye-like dorsal depression. Six Phymatodiscus species are reclassified as Bardizon: B. aokii (Hiramatsu, 1985), comb. nov., B. haradai (Hiramatsu, 1985), comb. nov., B. oculatus (Hirschmann, 1977), comb. nov., B. kuni (Kontschán & Starý, 2011), comb. nov., B. insolitus (Kontschán & Ripka, 2016), comb. nov., and B. malayicus (Kontschán & Starý, 2012), comb. nov. The new species differs from the previously described congeners in the sculptural pattern, the shapes of the dorsal and ventral setae, and the sculptural pattern of the sternal shield of the male and the genital shield of the female. A list of all known phymatodiscid species is presented. Phymatodiscus titanicus (Berlese, 1905) is moved to the genus Bostocktrachys: B. titanicus (Berlese, 1905), comb. nov. (family Trachyuropodidae).
