Abstract A new species of Aristolochia from the Atlantic Forest of Brazil is here described: A. insolita, from Rio de Janeiro, which belongs to subser. Hexandrae. This species, based on current knowledge, has a restricted distribution and does not occur in any conservation unit. A description, illustration, morphological comparisons, geographic distribution, and risk assessment are provided.

New records of Peperomia armondii Yunck, Peperomia hispidula (Sw.) A. Dietr., and Peperomia mandioccana Miq. for the state of Espírito Santo, southeastern Brazil

We present here the first record of Peperomia armondii , P. hispidula and P. mandioccana for the state of Espirito Santo, Brazil. Taxonomic comments, a distribution map and images of these species are presented.

On the typification, identity, and synonomy of Aristolochia disticha Mast. (Aristolochiaceae)

Aristolochia disticha was originally described based on a specimen collected by R. Spruce in Santarem (Pará, Brazil). Unfortunately, the specimen lacks flowers and fruits, although it has four slender, ramiflorous inflorescences that distinguish the species. Here we fully describe the species, based on the holotype and additional flowering and fruiting specimens that allow us to report a range expansion to the states of Acre, Amazonas, Bahia, Paraíba, and Rio Grande do Norte, Brazil, and also to Venezuela, French Guiana, Surinam, Peru, and Bolivia. Finally, we reduce the recently described A. setulosa to the synonymy of A. disticha.ResumoAristolochia disticha foi originalmente descrita com base em um espécime coletado por R. Spruce em Santarém (Pará, Brasil). Infelizmente, a amostra carece de flores e frutos, embora tenha quatro inflorescências ramifloras delgadas que distingue a espécie. Aqui é fornecida a descrição completa da espécie, com base no holótipo e em amostras adicionais com flores e frutos, que nos permite registrar uma ampliação de ocorrência da espécie para os estados do Acre, Amazonas, Bahia, Paraíba e Rio Grande do Norte (Brasil), e para Venezuela, Guiana Francesa, Suriname, Peru e Bolívia. Finalmente, é aqui considerada como sinônimo de A. disticha, a recentemente descrita A. setulosa.

New records of Pouteria macrocarpa (Sapotaceae) from the Brazilian Atlantic forest

Abstract We present the first voucher-based record of Pouteria macrocarpa for Brazilian Atlantic forest and extend the occurrence area of it. Besides, a brief taxonomic description, an identification key for lignified-fruits Pouteria species, and information about phenology and herbarium records are provided. According to the IUCN Red List and the Red Book of the Brazilian Flora, the species is considered Vulnerable (VU). However, facing the new available data, we believe it should be reassessed as Endangered (EN). Key words : Brazil, Chrysophylloideae, Ericales, Espirito Santo, Neotropics. Resumo Este e primeiro registro baseado em vouchers de Pouteria macrocarpa para a Mata Atlântica e informacoes sobre novas areas de ocorrencia da especie sao disponibilizadas. Alem disso, sao apresentadas uma breve descricao taxonomica, uma chave de identificacao de especies morfologicamente afins e informacoes fenologicas e das colecoes botânicas. De acordo com a Lista Vermelha da IUCN e do Livro Vermelho da Flora Brasileira, a especie e considerada Vulneravel (VU), no entanto, apos re-analise dos dados aqui apresentados,

Replacement names for two preoccupied generic names in Arthropoda

The genus Ransonia Blandin, 1979 (Arachnida: Araneae) was established with description of a new species, Ransonia mahasoana of the family Pisauridae (Arachnida: Araneae) endemic from Mahasoa, Madagascar. Unfortunately, this name is preoccupied by Ransonia Kramp, 1947, a genus of the family Rhopalonematidae (Hydrozoa: Trachymedusae) with only one species, Ransonia (Aglantha) krampi Ranson (1932), from Gibraltar, Mediterranean. According to article 60 of the International Code of Zoological Nomenclature a new substitute name is necessary, since Ransonia Blandin, 1979 does not have a junior synonym applicable and is a junior homonym of another genus. Therefore, we propose a replacement name for the spider genus as follows.

Three New Combinations and a New Synonym in the Subtribe Maxillariinae (Orchidaceae)

Based on previously published morphological and molecular analyses, a new classification for subtribe Maxillariinae (Orchidaceae) was proposed, and various genera were newly segregated. Among the combinations for species in those genera, three were not in accordance with the ICN. Here we propose three new combinations and a new synonym.
