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.

The orchid genus Phloeophila is distributed from southern Mexico to Brazil and Bolivia, as well as Cuba. A taxonomic revision including the three Phloeophila species present in Ecuador is presented. Morphological characteristics, an identification key, maps of known localities and illustrations of the species are also included. In Ecuador, species of Phloeophila are only known from the Amazonian rainforests, growing from 890 to 1600 meters of altitude. Phloeophila condorana is described as a new species based on specimens collected in the Ecuadorian province of Zamora-Chinchipe and compared to Phloeophila nummularia. Phloeophila nummularia is reported for the first time in Peru. A lectotype for Pleurothallis echinantha is selected.

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.

We here propose a new, monotypic genus, Amiga Nakahara, Willmott & Espeland, gen. n., to harbor a common Neotropical butterfly, described as Papilioarnaca Fabricius, 1776, and hitherto placed in the genus Chloreuptychia Forster, 1964. Recent and ongoing molecular phylogenetic research has shown Chloreuptychia to be polyphyletic, with C.arnaca proving to be unrelated to remaining species and not readily placed in any other described genus. Amigaarnacagen. n. et comb. n. as treated here is a widely distributed and very common species ranging from southern Mexico to southern Brazil. A neotype is designated for the names Papilioarnaca and its junior synonym, Papilioebusa Cramer, 1780, resulting in the treatment of the latter name as a junior objective synonym of the former. A lectotype is designated for Euptychiasericeella Bates, 1865, which is treated as a subspecies, Amigaarnacasericeella (Bates, 1865), comb. n. et stat. n., based on molecular and morphological evidence. We also describe two new taxa, Amigaarnacaadela Nakahara & Espeland, ssp. n. and Amigaarnacaindianacristoi Nakahara & Marín, ssp. n., new subspecies from the western Andes and eastern Central America, and northern Venezuela, respectively.

Molecular Phylogenetic Data

The snow hebes, formerly comprising the genus Chionohebe, are here included within Veronica (Plantaginaceae). The five species (including two subspecies) of snow hebes recognised here are cushions or subshrubs that occur exclusively in high-elevation habitats of Australia and the South Island of New Zealand. Species delimitation among the cushion snow hebes is very difficult because of the reduced pulvinate habit, solitary flowers and few gross-morphological characters useful for identification. To address species limits, investigate intraspecific patterns and revise the taxonomy of the snow hebes, morphological analyses were conducted and the results compared with previously published molecular phylogenetic data. Ordination and clustering analyses of morphological data showed some taxonomic structuring; however, species clusters were not widely separated from one another. Morphological and amplified fragment length polymorphism (AFLP) data show that the cushion species are clearly distinguished from the subshrub species, V. densifolia (F.Muell.) F.Muell. Among the four cushion species (V. chionohebe Garn.-Jones, V. ciliolata (Hook.f.) Cheeseman, V. pulvinaris (Hook.f.) Cheeseman, V. thomsonii (Buchanan) Cheeseman), the distribution of leaf trichomes is important for species identification, particularly when used in conjunction with ovary vestiture, capsule size, and/or seed size. One new combination V. ciliolata subsp. fiordensis (Ashwin) Meudt is proposed, and V. uniflora Kirk is treated as a naturally occurring hybrid V. × uniflora (V. densifolia × V. thomsonii). Complete synonymies, descriptions, illustrations and range maps are provided for each species, as well as a key to all species and a discussion of putative hybrids.

Field studies of the inselberg flora of north-eastern Brazil have resulted in the discovery of much greater morphological diversity of the genus Ameroglossum, than previously envisaged. These enigmatic plants are endemic to isolated rock outcrops, which have long been surrounded by unsuitable habitat. The morphological forms are geographically isolated and stable in cultivation when grown under similar conditions. We here provide detailed descriptions of the two previously known species and propose an additional seven new species in the genus. A taxonomic revision of the genus, including an identification key is provided. We hypothesize that the evolution of this genus is driven by the diversity of their hummingbird pollinators. Due to the threatened nature of inselberg habitats and the small populations found for most taxa, the species described here are likely to be under threat and in need for formal redlisting.

A taxonomic revision and nomenclatural update for Paspalum sect. Pectinata is presented. This section comprises seven species distributed from southern Mexico to Peru, Bolivia and southern Brazil, and is characterized by having linear to lanceolate blades, inflorescences subdigitate or conjugate with a winged rachis, and upper glume and lower lemma 3–7-nerved. We include 16 names and propose lectotypes for Paspalum aspidiotes, P. contractum, P. cordatum, P. lanciflorum and P. pectinatum. Also, after examination of herbarium specimens, a new synonym for Paspalum reticulinerve is proposed. The revision was based on a review of the relevant literature, study of types and materials from 43 herbaria. Descriptions, distribution maps, illustrations and comments are presented for each species, and a key to all species is included.

Abstract—Xylophragma (Tribe Bignonieae, Bignoniaceae) includes seven species of lianas or scandent shrubs. The genus is characterized by leaves 1‐5-foliolate with a simple tendril replacing the terminal leaflet, branched trichomes, calyx usually cuspidate, pink flowers, and ovary usually lepidote. The genus is distributed through dry forests from Mexico to Paraguay and Southern Brazil. We provide the first comprehensive taxonomic treatment for Xylophragma, including a detailed description of the genus, a key for all species, complete list of synonyms, descriptions and illustrations for all species, as well as information on the geographic distribution, habitat, phenology, conservation status, and taxonomic comments for all taxa. Overall, we analyzed more than 700 sheets deposited in 13 herbaria, including types for all accepted names and synonyms. We designate lectotypes for Arrabidaea clausseni, Arrabidaea elliptica, Arrabidaea macrophylla, Rojasiophyton tuberculatum, Saldanhaea myriantha var. pubescens, and a second step lectotype for Distictis rovirosana. Four new synonyms are proposed: A. claussenii as a synonym of X. corchoroides; S. pratensis and R. tuberculatum as synonyms of X. myrianthum; and X. unifoliolatum as a synonym of X. seemannianum.

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.

AbstractThe eastern Mediterranean basin hosts a remarkably high plant diversity. Historical connections between currently isolated areas across the Aegean region and long-distance dispersal events have been invoked to explain current distribution patterns of species. According to most recent treatments, at least two Cymbalaria species occur in this area, Cymbalaria microcalyx and C. longipes. The former comprises several intraspecific taxa, treated at different ranks by different authors based on morphological data, evidencing the need of a taxonomic revision. Additionally, some populations of C. microcalyx show exclusive morphological characters that do not match any described taxon. Here, we aim to shed light on the systematics of eastern Mediterranean Cymbalaria and to propose a classification informed by various sources of evidence. We performed molecular phylogenetic analyses using ITS, 3’ETS, ndhF and rpl32-trnL sequences and estimated the ploidy level of some taxa performing relative genome size measures. Molecular data combined with morphology support the division of traditionally delimited C. microcalyx into C. acutiloba, C. microcalyx and C. minor, corresponding to well-delimited nrDNA lineages. Furthermore, we propose to combine C. microcalyx subsp. paradoxa at the species level. A group of specimens previously thought to belong to Cymbalaria microcalyx constitute a well-defined phylogenetic and morphological entity and are described here as a new species, Cymbalaria spetae. Cymbalaria longipes is non-monophyletic, but characterized by being glabrous and diploid, unlike other eastern species. The nrDNA data suggest at least two dispersals from the mainland to the Aegean Islands, potentially facilitated by marine regressions.
