During the course of the taxonomic revision and molecular phylogeny of Pourouma, we encountered a new species from Peru and Ecuador. P. bergii Gaglioti & Romaniucis here described, illustrated and its morphological similarities to P. tomentosa subsp. persecta and P. petiolulata are discussed. A Conservation Assessment determines P. bergii to be Data Deficient (DD).

A New Species

A taxonomic revision of Flemingia subg. Rhynchosioides based on morphology and molecular information (matK and ITS) is presented. The subgenus comprises six herbaceous taxa (F. gracilis, F. mukerjeeana, F. nilgheriensis, F. rollae, F. tuberosa and F. vestita). All species except F. vestita are endemic to India. Morphological evidence and molecular phylogeny revealed that the subgenus is monophyletic. Nevertheless, the systematic position of F. tuberosa remains unclear on account of its unique ecology and inflorescence. A new species, F. mukerjeeana, is described and four binomials, namely F. gracilis, F. nilgheriensis, F. tuberosa and F. vestita have been lectotypified. Furthermore, all species have been described, illustrated and their ecology discussed. A taxonomic key including the recently described species from Thailand, F. sirindhorniae, is also provided for easy identification.

A New Species

The grass genus Poa L. is widespread throughout temperate areas of the Andes, being a common constituent in the highly diverse but threatened high-elevation páramo grasslands of northwest South America. Knowledge of Poa from these páramo areas is very limited, however, with no comprehensive taxonomic treatments available for Colombia, which contains the largest area of páramo in the Neotropics and its surrounding countries. We present a taxonomic revision of Poa for Colombia accepting 15 species, including two recent combinations of Poa previously circumscribed in Aphanelytrum (Hack.) Hack. We describe a new species, P. colombiana Soreng & Sylvester, and a new variety, P. subspicata (J. Presl) Kunth var. glabrata Soreng & Sylvester, for Colombia and Ecuador. Poa colombiana is similar to P. aequatoriensis Hack. but differs in having lemmas pubescent on the keel and marginal veins, lemma apices weakly acute, flag leaf sheath margins fused 20%–38% their length, and anthers generally larger, > 1.2 mm long. Poa subspicata var. glabrata differs from P. subspicata s. str. in having glabrous lemmas. We provide two new records for Colombia of P. huancavelicae Tovar, and P. mucuchachensis Luces. Two species, P. orthophylla Pilg. and P. reclinata (Swallen) Soreng & P. M. Peterson, are considered endemic to Colombia. Poa soderstromii Negritto & Anton is placed as a subspecies of P. orthophylla, and P. leioclada Hack. is synonymized under P. mulalensis Kunth. The names P. annua L. var. exilis Tomm. ex Freyn, P. humilis Ehrh. ex Hoffm., P. infirma Kunth, P. leioclada, P. orthophylla, P. pauciflora Roem. & Schult., P. pratensis L. subsp. irrigata (Lindm.) H. Lindb., P. puberula Steud., P. pubiflora Benth., P. subcaerulea Sm., P. subspicata, and P. trachyphylla Pilg. are lectotypified, P. mulalensis is neotypified, and P. trachyphylla is epitypified. Four species are exotic and introduced from Europe: P. annua, P. infirma, P. pratensis, and P. trivialis L. We provide a key, descriptions, illustrations, distribution and habitat information, vouchers, and notes for each species.

The genus Metalibitia Roewer, 1912, is revised for the first time, and a cladistic analysis revealed that it is a monophyletic clade. This cosmetid harvestmen genus is restricted to open forests and adjacent vegetational formations in South America (humid Forest, being found mostly in the region of cerrado/chaco/pampas). An identification key for all known species is presented and a new species is described, Metalibitia abuna sp. nov. (type locality: Abunã, Porto Velho, Rondônia, Brazil). Two species, Paralibitia maculata Roewer, 1914 and Labrosa arenosa Mello-Leitão, 1939, are here synonymized under Metalibitia argentina (Sørensen, 1884).

Abstract— Lasiocarpus is a genus of bisexual, dioecious, or trioecious shrubs or small trees of Malpighiaceae endemic to the seasonally dry tropical forests of the Pacific slopes of Mexico. In this paper the monophyly of this genus is tested using a molecular phylogeny based on three plastid (ndhF, matK, rbcL) and a single nuclear (PHYC) markers that were newly sequenced for the three currently accepted species in this genus, along with representative taxa from the main phylogenetic groups previously recognized in Malpighiaceae. The three species of Lasiocarpus were retrieved in a well supported clade corroborating the monophyly of this genus. A taxonomic treatment of this genus is presented. Lasiocarpus ovalifolius is synonymized with L. salicifolius, and a new species, Lasiocarpus andersoniorum, endemic to Southern Mexico, is proposed. It is morphologically distinguished by characters such as axillary inflorescences, reflexed sepals, petals with crenate margin and strigose indumentum, large styles, and 2-lobed stigmas. The taxonomic revision includes morphological descriptions and distribution maps for the three accepted species of Lasiocarpus.

A New Species

The first molecular phylogeny of Lynceus (Crustacea: Branchiopoda: Laevicaudata) is presented together with a description of a new species of laevicaudatan branchiopod from Chile, Lynceus huentelauquensis, sp. nov. DNA sequences were obtained from six species of Lynceus using freshly collected specimens from Europe, North America, South America, and Australia and combined with GenBank sequences from previous studies. Specimens of the new species were collected from a pool on the Huentelauquén Plains near Huentelauquén City. Our molecular analyses placed L. huentelauquensis, sp. nov. within Lynceus and close to a cluster of Australian species, and revealed morphological misidentifications, cross-contamination, or incorrect upload in earlier GenBank sequences. L. huentelauquensis, sp. nov. is separated from other Lynceus primarily by the morphology of the rostrum and the male claspers. L. huentelauquensis, sp. nov. is the first described laevicaudatan from Chile, the sixth from South America, and the 13th from the Americas. The morphology of laevicaudatans from the Americas is reviewed and an updated key to the (male) Lynceidae of the region is provided. Our study highlights the necessity of a revision of Laevicaudata using multiple genetic markers as well as thorough morphological studies on a greater number of taxa. urn:lsid:zoobank.org:pub:9A783D96-B270-40DF-8361-11BA063C9A0F

A new species, Brownlowia latifiana (Malvaceae-Brownlowioideae), endemic to Terengganu, Peninsular Malaysia, is described and illustrated. This new species has most of its morphological characters that are related to those of the genus Jarandersonia. Therefore, a standard morphological taxonomic revision and morphometric analysis were carried out to assess the status of Brownlowia latifiana. Results of the morphometric analysis based on morphological characters showed that Brownlowia latifiana is embedded within the clades of Brownlowia but distanced from the clades Jarandersonia. Brownlowia formed a distinct clade in the clustering tree well separated from the Jarandersonia. A distribution map and a conservation assessment using the IUCN Red List categories and criteria are provided.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.
