The grammitid genus Parrisia was named recently in a paper by Shalisko et al . (2019) to accommodate two species previously treated in Enterosora by Bishop & Smith (1992) , Smith & Bishop (1995) , and Smith et al . (2018). Parrisia parietina is widespread, from southern Mexico to Bolivia ; a second species, P. gilpinae (Baker) Shalisko & Sundue , is in Tanzania and Madagascar , and was treated under the name E. sprucei (Hook.) Parris ( Parris 2005 ) , which we consider a synonym of P. parietina . This unusual distribution pattern of Parrisia is also known in several other grammitid genera, e.g., Ceradenia , Enterosora , Grammitis s.s . , Leucotrichum , Melpomene , Moranopteris , and Stenogrammitis . Previously, species in Parrisia have generally been placed either in a very broadly defined genus Grammitis , a definition that included all or nearly all grammitid ferns (700+ spp.), or in Enterosora ( Bishop & Smith 1992 ; Smith et al . 2018). Parrisia agrees with Ceradenia , Enterosora , Grammitis s.s . , and several other grammitid genera in lacking clearly defined hydathodes adaxially. From Enterosora , Parrisia is distinguished by the radial rhizomes (vs. dorsiventral), the sori borne at the middle of veins (vs. distally), and the presence of setae around the sori ( Shalisko et al . 2019 ). From other simple-bladed New World grammitids, e.g., Cochlidium , Parrisia differs in lacking hydathodes, the presence of dark-colored setae on the blades, and from some species by the superficial sori (vs. immersed coenosori). Another simple-bladed genus in the Neotropics is Lomaphlebia , endemic to the Greater Antilles; that genus has a row of marginal areoles on the blades. Grammitis s.s . , also simple-bladed, differs in having black sclerotized blade margins and general lack of setae abaxially on the blades. Phylogenetic studies suggest that Parrisia may be related to the endemic Hawaiian genus Adenophorus , with species having distinctive reddish glandular paraphyses in the sori and on the lamina abaxially, to Antillean Lomaphlebia (2 spp.), and to the amphioceanic genera Grammitis s.s . and Cochlidium (all but one species neotropical). Affinities with Enterosora (see above; now including Zygophlebia ) are more remote ( Bauret et al . 2017 ; Shalisko et al . 2019 ). The current name for the Bolivian species is:
