The millipede genus Poratia Cook & Cook, 1894 is redefined and shown to be Neotropical (Central and northern South America), with the follow- ing junior subjective synonyms: Dominicodesmus Cham- berlin, 1923; Tidopterus Chamberlin, 1923; Kapyrodes- mus Attems, 1940, syn.n.; Muyudesmus Kraus, 1960, syn.n.; and Poratioides Loomis, 1970, syn.n. The fol- lowing seven valid species are currently assigned to Poratia: (1) P. digitata (Porat, 1889) (= the type species Scytonotus digitatus Porat, 1889; = Poratia heterotu- berculata Carl, 1902; = ?Dominicodesmus panamicus Chamberlin, 1940; = Poratioides virginalis Loomis, 1970, syn.n.; = Poratioides disparatus Loomis, 1973, syn.n.); (2) P. mulegensis (Chamberlin, 1923) (= Xe- rodesmus mulegensis Chamberlin, 1923; = Domini- codesmus geophilus Chamberlin, 1923); (3) P. sequens (Chamberlin, 1923) (= Tidopterus sequens Chamberlin, 1923); (4) P. insularis (Kraus, 1960) (= Muyudesmus insularis Kraus, 1960); (5) P. obliterata (Kraus, 1960) (= Muyudesmus obliteratus Kraus, 1960); (6) Poratia fossata Loomis, 1964; and (7) Poratia salvator sp.n. Treseolobus granulofrons Chamberlin, 1918 is trans- ferred to Docodesmus Cook, 1896, comb.n. Poratia digitata, as a strictly parthenogenetic form, occurs com- monly in European green houses, also known from open habitats in Java and the southern U.S.A. and is recorded here from North American green houses for the first time. P. obliterata is bisexual throughout Amazonia as well as in Costa Rica and perhaps Panama, but distinctly parthenogenetic in a few European hothouses. Partheno- genesis is likewise characteristic of P. mulegensis, at least so in the Caribbean. A character table and a key to Poratia species have been compiled.
