AbstractFlavobathelium epiphyllum gen. et sp. nov. is described and illustrated. The new taxon is characterized by perithecia and pyenidia embedded in pulverulaceous, uni- to plurilocular pseudostromata, small, transversely septate ascospores, and the presence of bacillar to filiform macroconidia with gelatinous appendages and simple microconidia. Possible relationships are seen with the genus Phyllobathclium. Flavobathelium epiphyllum is a common species in Central and South American lowland to submontane rain forests with undisturbed vegetation. It is mostly found along moderately illuminated parts of the understory, such as small, natural light gaps.

A New Species

A new species of Maytenus has been discovered in the Brazilian Atlantic Forest. The new taxon, Maytenus nemorosa, occurs mostly in ombrophilous rain forests at an elevation of 500 m to 1200 m. Maytenus nemorosa resembles M. gonoclada but differs from it by possessing oblong-elliptical leaves with entire margins and larger fruits with thicker pericarp walls. A phylogenetic analysis was conducted with nrITS and plastid matK regions, including the new species and additional taxa available from the NCBI-GenBank. The results from the phylogenetic analysis places Maytenus nemorosa nested within a clade of species that have fruits possessing a coriaceous pericarp and close to both Maytenus gonoclada and Maytenus salicifolia, as expected from morphological similarities. Additionally, M. cardenasii and M. erythrocarpa, from Bolivia, are both recognized as new synonyms for M. floribunda after an examination of their descriptions, types, and diverse collections.

New Form

Rhynchocephalian lepidosaurs, though once widespread worldwide, are represented today only by the tuatara ( Sphenodon ) of New Zealand. After their apparent early Cretaceous extinction in Laurasia, they survived in southern continents. In South America, they are represented by different lineages of Late Cretaceous eupropalinal forms until their disappearance by the Cretaceous/Palaeogene (K/Pg) boundary. We describe here the only unambiguous Palaeogene rhynchocephalian from South America; this new taxon is a younger species of the otherwise Late Cretaceous genus Kawasphenodon . Phylogenetic analysis confirms the allocation of the genus to the clade Opisthodontia. The new form from the Palaeogene of Central Patagonia is much smaller than Kawasphenodon expectatus from the Late Cretaceous of Northern Patagonia. The new species shows that at least one group of rhynchocephalians not related to the extant Sphenodon survived in South America beyond the K/Pg extinction event. Furthermore, it adds to other trans-K/Pg ectotherm tetrapod taxa, suggesting that the end-Cretaceous extinction affected Patagonia more benignly than the Laurasian landmasses.

AbstractTrichothelium argenteum R. Lücking & L. I. Ferraro sp. nov. is distinguished by its very large perithecia with a well-developed, silvery white, basally black crown of setae, and by a non-radiate phycobiont. In young perithecia, the setae are confluent and form a characteristic, two-coloured disc-like expansion. Ascospores are 7-septate and bacillar. Trichothelium argenteum is known from a few populations in Costa Rica, Ecuador, Brazil, Paraguay, and Argentina.

Two New Species

Two new species of the South American genus Lessingianthus (Asteraceae: Vernonieae) are described and illustrated. One of these species, Lessingianthus arctatus, bears a resemblance to L. linearis (Spreng.) H.Rob. and L. rosmarinifolius (Less.) H.Rob., but can be separated from them by its almost glabrous phyllaries, solitary heads and longer internodes. The other new taxon, Lessingianthus longicuspis, can be easily separated from L. cataractarum (Hieron.) H.Rob. and L. bardanoides (Less.) H.Rob., and other taxa of the genus, by the combination of petiolate leaves, aristate phyllaries and inflorescence bracts alternate to the heads. Four other taxa previously included in Vernonia are transferred to the genus Lessingianthus.

New Discovery

Abstract Rhabdias pocoto n. sp. is herein described from the lungs of the swamp frog Pseudopaludicola pocoto Magalhães, Loebmann, Nogueira, Kokubum, Baptista, Haddad & Garda, 2014, from the Caatinga biome in the state of Ceará, in north-eastern Brazil. The new species is characterized by a body that dilates posteriorly, six small lips (protuberances) and two rounded lateral expansions of cuticular inflation on the anterior end, each containing an amorphous gland-like structure inside and a short and conical tail. Additionally, molecular analysis and comparison of the partial mitochondrial cytochrome c oxidase I sequence of R. pocoto n. sp. revealed genetic divergence between the new species and the sequences of Rhabdias spp. previously deposited in GenBank. Phylogenetic analysis grouped the new taxon into the R. pseudosphaerocephala species complex + R. glaurungi clade. The new discovery represents the 19th species of Rhabdias spp. described in the Neotropical region, the ninth in Brazil and the first species of Rhabdias found parasitizing South American frogs of the genus Pseudopaludicola, as well as the first Caatinga biome species of Rhabdias.

A New Species

The South American genus Cardioscarta Melichar, 1932 includes seven species of colorful sharpshooters. Here we describe and illustrate an additional species, C. aurantia sp. nov., from the Atlantic Forest of southeastern Brazil (state of Rio de Janeiro). The new taxon can be distinguished by the dark brown to black forewing with two large orange areas, one from basal portion of corium to distal portions of discal cells and another covering most of clavus, or with single large orange area on basal two-thirds. A key to species of Cardioscarta is provided and the new species is compared with the other ones of the genus.

A new species, Strobilomyces pteroreticulosporus, is described based on two recent collections from the Republic of Korea. This new taxon is well characterized by morphological characters, and proved using rpb1 and ITS2 sequences. The variability of size and basidiospore ornamentation of the common species S. confusus is also discussed.

Insight Into

AbstractPorina pseudoapplanata Lücking & Cáceres sp.nov. is characterized by its foliicolous growth habit, a thin, nitidous thallus without crystals, applanate, yellowish red perithecia narrowly bacillar, 7-septate ascospores, and the presence of previously unrecognized isidi belonging to the Phyllophiale-type, here formally described as P. viridis Lücking & Cáceres sp.nov. The interpretation of Phyllophiale representing isidia of Porina species is discussed. Porina pseudoapplanata is similar to species in the P. rufula group, i.e. P. monocarpa (Kremp.) F. Schill., P. cupreola (Müll. Arg.) F. Schill., P. planiuscula Vêzda and, in particular, P. applanata Vain. However, it seems most closely related to P. mirabilis Lücking & Vězda in the P. epiphylla group, from which it differs by the complete absence of crystals in the thallus and perithecia. This gives a further insight into systematic relationships within the Trichotheliaceae. Keys are presented to distinguish P. pseudoapplanata from similar and related species, as well as to the known species of Phyllophiale.
