Sirodotia amazonica Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov. is very similar to two species found in Brazil, S. delicatuliformis Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov. and S. cryptica Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov., overlapping for most morphometric and morphological characters. However, S. amazonica Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov. is distinguishable from S. delicatuliformis sp. nov. based on the wider carposporangia (8-13 versus 6-8.5(-9.5) µm in diameter).</p></div>	https://treatment.plazi.org/id/038C879A5F41FF9FFEB0F9D7FF45FE7A	Public Domain	No known copyright restrictions apply.

Like these species, it has large carposporangia, spermatangia single or in pairs on primary fascicles and gonimoblast initial developing from the protuberant side of carpogonium. It is distinguishable from those species only in its geographic distribution (restricted to Asia versus Americas). Sirodotia delicatula has been recorded from Indonesia and Japan and more recently reported from Malaysia including rbc L sequences (Johnston et al. 2014). It had been previously reported in South America (Brazil) (Necchi 1991; Necchi et al. 1993, 2007; Paiano &amp; Necchi 2013). However, Asian specimens are distinguishable from South American ones based on the divergences in the DNA sequences and in the known geographic distribution (Asia versus South America). Since Malaysia is closer to the type locality, the Asian specimens are regarded as representing the species. Sirodotia ateleia Skuja was considered a synonym of S. delicatula by Umezaki (1960) and Necchi (1991) based on a combination of morphological characters. On the other hand, based on the examination of North America populations identified as S. huillensis and the type of S. ateleia, Necchi et al. (1993) considered these two taxa to be synonymous by the size and shape of the whorls. In this study we followed the proposal by Umezaki (1960) and Necchi (1991) of S. ateleia being synonymous with S. delicatula based on similarity of morphological characters and geographic distribution in Asia, although S. ateleia has longer carpogonia (42-70 µm versus (19-)24-57 µm in length).</p></div>	https://treatment.plazi.org/id/038C879A5F46FF9BFC07FF72FE10FD5B	Public Domain	No known copyright restrictions apply.

Based on recent studies including molecular data (Paiano &amp; Necchi 2013; Johnston et al. 2014; this study), the sequences from South and North America were showed to be genetically divergent from the sequence of S. delicatula from Malaysia.Thus, it represents a distinct species that is here described. The species is highly divergent in sequence from S. delicatula . However, these two species are morphologically very similar with considerable overlap for all morphological characters, but the disjunct geographic distribution that can be applied as criterion to distinguish them. In addition, this species formed a lineage with three other species ( S. amazonica Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov., S. cryptica Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov. and S. aquiloamericana) from North and South America. The morphology among these species is similar, but S. delicatuliformis Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov. is distinguishable from S. amazonica and S. cryptica based on the narrow carposporangia (6-8.5(-9.5) versus 8-13 µm in diameter), and from S. aquiloamericana by having smaller whorls (169-491 versus 408-675 µm in diameter).</p><p>Sirodotia huillensis (Welwitsch ex West &amp; G.S.West) Skuja</p><p>(Fig. 6 A-E)</p><p>Archiv für Protistenkunde 74: 304 (Skuja 1931). — Batrachospermum huillense Welwitsch ex West &amp; G.S.West, Journal of Botany 35: 3 (West &amp; West 1897).</p><p>TYPE. — F.

However, S. huillensis differs from S. kennedyi in having a greater number of cells in primary fascicle (5-9(-10) versus 3-5), a small number of cells in the carpogonial branches (1-3 versus 3-4), a shorter carpogonial branch (5-14 versus 16-22 µm in length) and a greater number of cells in the erect gonimoblast filament (2-4 versus 1-2, Appendices 4-6). In addition, they are genetically divergent. In the description of this species from Africa (Madagascar and Reunion) bySkuja (1931) and then later by Necchi et al. (1993) in specimens from North America (Arizona and Texas), this species was reported to have spermatangia arranged in clusters. However, this type of arrangement, characterized by the terminal and subterminal cells bearing two to four spermatangia, was not confirmed in the type or protologue. That arrangement of spermatangia in clusters was observed only in S. assamica, whereas in some populations of S. huillensis only abundant and densely arranged spermatangia were found. The species referred by Lam et al. (2012) as S. aff. huillensis (BHO A-1447), which was analyzed in this study, could not be conclusively identified based on morphology for the limited morphological characters provided or examined. Phylogenetic analyses based on molecular data (Lam et al. 2012; this study) of the specimen referred to as S. aff. huillensis collected in South Africa was genetically distinct from specimens described as S. huillensis from North America. Therefore, the specimen, S. aff. huillensis, collected closer to type locality of S. huillensis, is interpreted as S. huillensis and the North American specimens represent another species ( S. aquiloamericana).</p></div>	https://treatment.plazi.org/id/038C879A5F44FF85FEDEFCB0FD4BF887	Public Domain	No known copyright restrictions apply.

It is comparable to the other species with large carposporangia and spermatangia 1-3 on primary fascicles (e.g. S. delicatula, S. delicatuliformis Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov., S. amazonica Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov., S. cryptica Necchi, N.L.Rossignolo &amp; M.O.Paiano, sp. nov. and S. aquiloamericana). The species is clearly differentiated by the unique character of gonimoblast initial developing from the non-protuberant side of the carpogonium.Molecular data also showed the species to be clearly distinct from all others in the genus (rbc L, COI-5P and LSU). The heterotypic synonyms considered in this study were based on the analysis of types, protologues and when possible, molecular data. The morphological characters used to distinguish these species ( S. fennica, S. sinica, S. tenuissima, S. acuminata, S. segawae, S. yutakae and S. goebelii) overlap most characters (breeding system, internode length, carpogonial branch growth and length and carpogonia length) of S. suecica and they are not useful due to the variation observed across this species. Molecular data for S. tenuissima and S. goebelii showed these taxa to have very similar rbc L sequences to S. suecica (Lam et al. 2012) . Based on the analysis of type specimens and protologues of S. segawae and S. yutakae, we did not confirm the existence of specialized spermatangial branches on primary fascicles and secondary fascicles ( S. yutakae) or on specialized filaments on cortical filaments or on shortened involucral filaments of carpogonial branches ( S. segawae). We conclude that S. segawae, S. yutakae and S. sinica should be placed in synonymy with S. suecica . Overall, we accept only one taxon including these other names as synonyms, that is characterized by the gonimoblast initial developing from the opposite side of the basal protuberance of carpogonium.</p></div>	https://treatment.plazi.org/id/038C879A5F5AFF87FC17F997FB03FC04	Public Domain	No known copyright restrictions apply.
