During a taxonomic revision of species belonging to Phylloporia, some collections from the Atlantic Forest of southern Brazil previously determined as P. spathulata had morphological discrepancies in comparison to the type material of this taxon. Both molecular phylogenetic and morphological analysis revealed them to be two distinct species, described here as Phylloporia elegans sp. nov. and P. nodostipitata sp. nov. They mainly differ from P. spathulata by having reviving basidiomata with smaller pores and basidiospores. Phylloporia nodostipitata develops caespitose basidiomata with a knotted and flexuous stipe and a tomentose pileal surface. Phylloporia elegans develops solitary basidiomata with a cylindrical and straight stipe and a plagiotrichoderm pileal surface. Both species are described, illustrated, discussed and compared with Phylloporia spathulata based on a study of the type. Phylloporia spathulata sensu stricto is presented based on its basionym type material.

Abstract Background Barbels are ray finned cyprinid fishes of the Old-World with partially unresolved, intricate taxonomy. Within the Barbus sensu lato paraphyletic assemblage, Barbus sensu stricto is a monophyletic tetraploid lineage of Europe, northern Africa and Middle East, including two monophyletic sibling genera: Barbus and Luciobarbus. Italy, Slovenia and northern Croatia are natively inhabited by several entities of the genus Barbus, whose relationships and taxonomic ranks are still unclear. Aim of the present work is to focus on phylogeography of Italian and Slovenian barbels, with an appraisal of their current taxonomy. Results One hundred fifty specimens were collected in 78 sampling sites from 33 main watersheds, widely distributed along Italian and Slovenian ichthyogeographic districts. We amplified two mitochondrial markers, cytochrome b (cytb) and control region (D-loop), to infer a robust phylogeny for our sample and investigate on species delimitation. Our results strongly indicate all Italian and Adriatic Slovenian fluvio-lacustrine barbels to be comprised into at least three distinct species. We provide a proposal of taxonomic revision and a list of synonymies for two of them and a new description under the International Code of Zoological Nomenclature rules for the third one. Conclusions If nuclear data will confirm our findings, at least three specific entities should be acknowledged across our sampling area. Namely, the three species are (i) Barbus plebejus, in the Padano-Venetian district; (ii) Barbus tyberinus, in the Tuscany-Latium district; (iii) Barbus oscensis Rossi & Plazzi sp. nov., in the Tyrrhenian and southernmost-Adriatic parts of Apulia-Campania district. Finally, we briefly discuss the implications of such a taxonomic scenario on conservation policies.

Neosadocus harvestmen are endemic to the Southern Brazilian Atlantic Forest. Although they are conspicuous and display great morphological variation, their evolutionary history and the biogeographical events underlying their diversification and distribution are still unknown. This contribution about Neosadocus includes the following: a taxonomic revision; a molecular phylogenetic analysis using mitochondrial and nuclear markers; an investigation of the genetic structure and species' diversity in a phylogeographical framework. Our results show that Neosadocus is a monophyletic group and comprises four species: N. bufo, N. maximus, N. robustus and N. misandrus (which we did not find on fieldwork and only studied the female holotype). There is astonishing male polymorphism in N. robustus, mostly related to reproductive strategies. The following synonymies have resulted from this work: Bunoweyhia variabilis Mello-Leitão, 1935 = Neosadocus bufo (Mello-Leitão, 1926); and Bunoweyhia minor Mello-Leitão, 1935 = Neosadocus maximus (Giltay, 1928). Most divergences occurred during the Miocene, a geological epoch marked by intense orogenic and climatic events in the Brazilian Atlantic Forest. Intraspecific analyses indicate strong population structure, a pattern congruent with the general behavior and physiological constraints of Neotropical harvestmen.

Phylogenetic studies indicate that several infrageneric taxa in Oxalis require taxonomic updates to attain monophyly. In this contribution, we update the morphological delimitation of the South American Oxalis sect. Ripariae and provide a taxonomic revision of the currently accepted species. The sectional delimitation was carried out by comparing micro- and macromorphological features of Oxalis sect. Ripariae, O. sect. Corniculatae, and O. sect. Myriophyllum. These sections share yellow flowers and aerial stems. Glandular hairs and larger seeds with the surface longitudinally crested and with projections are exclusive to Oxalis sect. Ripariae. We accept 11 species in the section, including three previously placed in Oxalis sect. Corniculatae (i.e., O. eriocarpa, O. niederleinii, and O. refracta), but excluding O. serpens and O. subvillosa, which are moved to O. sect. Corniculatae. We also describe a new species (Oxalis lourteiginana), propose a new name and status for O. bifrons subsp. littoralis (now O. pampeana), the synonymization of O. irreperta with O. riparia, six second-step lectotypifications, and one epitypification. For each accepted species we provide a morphological description, illustrations, ecological and taxonomic information, conservation status following IUCN, and a geographic distribution map. Most species occur in southern Brazil, but the section is widespread also in Argentina, Uruguay, and eastern Paraguay. Six species are categorized as threatened and further three as near threatened. Besides, we provide an identification key for the taxa of the section.

Close examination of Orthoprotella mayeri K.H. Barnard, 1916 (sensu lato) which has been recorded from South Africa and New South Wales, Australia, revealed that there are two distinct species from Cape Province, South Africa and New South Wales, Australia, respectively. The present paper provides a redescription of O. mayeri K.H. Barnard, 1916 (sensu stricto) from South Africa and a description of O. berentsae sp. nov. from New South Wales, Australia. The two species can be identified based on the morphology of antenna 2, pereonites 6 and 7, and the uropods, although characteristic body somites of both species resemble other species.

Abstract Paracanthon Balthasar 1938 includes four nominal species of dung beetles occurring in the Atlantic Forest of northeastern, southeastern and southern Brazil, and Misiones, Argentina. Here we describe twelve new species of Paracanthon: P. arnaudi sp. n., P. belloi sp. n., P felipei sp. n., P genieri sp. n., P. grossiorum sp. n., P. laevinotus sp. n., P. lopesandradei sp. n., P. marinezae sp. n., P. millerorum sp. n., P.monteiroorum sp. n., P. muriloi sp. n., P. ocellatopunctatus sp. n. We propose P. pereirai d’Andretta & Martínez 1957 as a new junior subjective synonym of P. rosinae Balthasar 1942. In addition, we present new data on the morphology of the hindwings and male genitalia, and an identification key to the species of the genus. Paracanthon is restricted to the Atlantic domain, and we briefly discuss the possible processes that might have led to the diversification of the putative lineages recognized here.

A New Species

Using the moss genus Rhynchostegiella (Brachytheciaceae) as a model, we address the question of whether taxonomic shortcomings account for the extremely low rates of endemism reported in the Azorean bryophyte flora. Eight accessions initially assigned to three of the four previously reported species in the Azores were identified as a distinct species using the Generalized Mixed Yule Coalescent method in the context of a molecular phylogenetic analysis of the genus. Rhynchostegiella azorica sp. nov. is therefore described as a new species that is endemic to the Azores. Its morphological features intergrade with those observed in other species, with a seta that ranges from almost smooth to rough; a length to width ratio of the laminal cells that matches the one of the R. curviseta group; but a leaf apex that is typical of the R. tenella group. This suggests that previous reports of four Rhynchostegiella species from Azores are erroneous and that a single, morphologically variable species, R. azorica, occurs in the archipelago. Rhynchostegiella azorica is sister to the remainder of the species of the genus, whose most recent common ancestor was dated at 4–20 Ma. This points to a more ancient origin in comparison with other Macaronesian endemic species of the genus. The unexpected discovery of an Azorean endemic species in Rhynchostegiella suggests that patterns of endemicity in the Azorean bryophyte flora are not well estimated from traditional taxonomic knowledge and point to the necessity of an extensive integrative taxonomic revision.

Here we present a first contribution to the taxonomic revision of Sisyrinchium (Iridaceae: Iridoideae) for Southern Brazil. Sisyrinchium sect. Cephalanthum is one of the six sections in which the Brazilian species of the genus are classified, and the second largest in number of taxa. This monograph presents the taxonomic treatment of 22 taxa characterized by a unique set of morphological and molecular features, assigned to the section by phylogenetic studies, as well as the unplaced S. elegantulum, which is included here due to morphological similarity. A new status and a new synonym are proposed, and nine lectotypes and one neotype are designated. An identification key is provided, and species are described, accompanied by botanical illustrations, pictures, and distribution maps. In addition, geographical distribution, habitat, phenology, notes, and examined specimens are presented. Species of the section are mainly distributed in the South American biogeographic dominions of Chacoan and Parana.

Molecular Phylogenetic Data

Tynanthus is a genus of Neotropical lianas that are distributed from southern Mexico to southern Brazil. Extensive herbarium work, field studies and new molecular phylogenetic data were used as the basis to recognize 14 species in the genus. Here, we provide a detailed treatment of the group, including an identification key to all species recognized, as well as morphological descriptions, a complete list of synonymy, nomenclatural information, taxonomic notes, phenological data, information on habitat and distribution, and illustrations. Two species are circumscribed differently from earlier classifications, in particular Tynanthus elegans is synonymized with Tynanthus cognatus, while Tynanthus villosus is synonymized with Tynanthus polyanthus. In addition, Tynanthus goudotianus is treated as a doubtful name, and two recently described species are recognized, Tynanthus densiflorus and Tynanthus espiritosantensis. One species name is neotypified, Tynanthus caryophylleus, and nine species names are lectotypified, namely Cuspidaria ovalis, Tynanthus cognatus, Tynanthus elegans, Tynanthus guatemalensis, Tynanthus lindmanii, Tynanthus myrianthus, Tynanthus panurensis, Schizopsis chimonantha, and Schizopsis regnelliana. A complete list of doubtful and excluded names is presented.

Nopyllus gen. nov. is proposed to include Apopyllus isabelae Brescovit & Lise, 1993 and Nopyllus vicente sp. nov. from southern Brazil. Nopyllus gen. nov. is close to Apodrassodes Vellard, 1924 and Apopyllus Platnick & Shadab, 1984, can be distinguished from both genera by the absence of a dorsal abdominal scutum in males, the absence of a median apophysis on bulb, the curved, narrow and reniform cymbium, and by the presence of a very conspicuous cymbial basal projection.
