FAMILY DUPLORBIDAE HØEG & RYBAKOV, 1992

Type genus: Duplorbis Smith, 1906 .

Type species: Duplorbis calathurae Smith, 1906 .

Diagnosis (amended): The cyprids have long and thick frontal filaments. Additional characters are externae with a mesenteric canal, as in chthamalophilids but lacking the double cuticle and refringent appearance of this family. The male organs are spermatogenic islets that originate as in the Chthamalophilidae , but they continue to be sheathed in a cuticle that continues to increase in thickness, and spermatogenesis proceeds without any formation of secondary islets ( Mourey, 1974; Høeg & Rybakov, 1992).
