A New Species

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

A New Species

A new species, Calea arachnoidea, which belongs to Calea sect. Meyeria, is hereby described and illustrated. This species occurs in the Serra Negra region, located in the southern portion of the “Zona da Mata” in the state of Minas Gerais, southeastern Brazil. Calea arachnoidea resembles C. quadrifolia, C. heteropappa and C. semirii, and its relationships with these species are discussed and an identification key for the species of C. sect. Meyeria in the state of Minas Gerais is provided. Additionally, photographs, a distribution map, comments about habitat and conservation status are provided.

The orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the “Centro de Endemismo Pernambuco”, northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging to Usina Serra Grande, in the states of Alagoas and Pernambuco, were surveyed using seventeen different scents as baits to attract orchid-bee males. Eight sites were established in the three preserves, where samplings were carried out using two protocols: insect netting and bait trapping. We collected 3,479 orchid-bee males belonging to 29 species during 160 hours in early October, 2012. Seven species were collected in the “Centro de Endemismo Pernambuco” for the first time. Richness proved to be one of the highest of the entire Atlantic Forest domain, and diversity in some sites, especially at ESEC Murici, revealed to be one of the highest in the Neotropics. Eulaema felipei Nemésio, 2010, a species previously recorded only at ESEC Murici, was found in no other preserve in the region and its conservation status is discussed.

This study report the first record of Allamanda blanchetii Kunth in the Atlantic Forest, Brazil. This species was collected from an upland forest in Semi-deciduous Seasonal Forest. This occurrence adds new information about the distribution of this species and expands its range to Brazil, which is important for its conservation. We provide taxonomic information, distribution maps, conservation status assessment, photograps, and an identification key for the Allamanda L. species in the Atlantic Forest.

Abstract Piresia, a small genus of herbaceous bamboos, has a geographical disjunction between the Caribbean and northern/western South America and the north-eastern Atlantic Forest in Brazil. Piresia leptophylla is reported from western Amazonia (WA) and the north-eastern Atlantic Forest (NAF), but its occurrence in western Amazonia is questionable. Using an integrative approach, we combined traditional morphological analysis, anatomy and niche modelling. The results revealed few macromorphological differences between WA and NAF specimens (only plant height, leaf length, lodicule dimensions, shape and position), contrasting with consistent differences in leaf anatomy (macrohairs and cruciform silica bodies in the costal zone of the adaxial/abaxial leaf surfaces, crenate silica bodies on the abaxial leaf surface, lack of panicoid hairs on the abaxial leaf surface, bicellular microhairs and lobed papillae over the abaxial leaf surface, and sparse but elongated fusoid cells in the mesophyll of WA specimens) and in niche patterns. The anatomical/micromorphological characters suggest environmental adaptations to the Amazonian and ‘restinga’ forests, respectively. We therefore propose the segregation of the WA populations into a new species, Piresia tenella sp. nov. We provide a formal description, photographs, a line illustration, a distribution map and discussion of the conservation status for the new species.

There are described and illustrated Eugenia mimetica and E. sudestis. Eugenia mimetica is related to E. praeterita, but has smaller blades and shorter inflorescences. Eugenia sudestis is close to E. persicifolia but has glabrous blades and auxotelic inflorescences. Additionally, topics on distribution, phenology, habitat and conservation status are commented for each species.

High Diversity

Brazil includes a very high diversity of bamboos, but this diversity is far from completely known. We increase the list of Brazilian woody bamboos by describing two new species of Chusquea, which belong to subgenus Rettbergia. Chusquea ciliatifolia sp. nov. differs from other species of this subgenus by its mottled culms, distinctly ciliate margins of the foliage leaf blades and pilose synflorescences; and C. mirabilis sp. nov. by the presence of branches with sericeous girdles. Both C. ciliatifolia and C. mirabilis occur exclusively in the Atlantic Forest, from the states of Bahia and Minas Gerais, known only from five and three populations, respectively. Comments on morphology, taxonomic relationships, ecological aspects, and conservation status of these new species are provided.

The Bahian giant tree rat Phyllomys unicolor (Wagner) was described from a single specimen collected in the early nineteeth century, and it has not been recorded since. It was included on the Brazilian endangered species list, and considered extinct by some. Here we report the rediscovery of P. unicolor around the type locality in the Atlantic forest of southeastern Bahia, eastern Brazil. We trapped only one young individual during seven expeditions to ten localities in the area. The phylogenetic distinctiveness of this taxon based on the mitochondrial cytochrome b gene is clear, in spite of uncertainties regarding clade support. The evolutionary uniqueness of P. unicolor was confirmed by a high level of sequence divergence from congeneric species. We propose that the Bahian giant tree rat should be globally listed as Critically Endangered by the World Conservation Union. Phyllomys unicolor seems to be restricted to swamp forests and it does not occur in any protected area. Intensive field studies should be carried out in the region to locate populations and to study ecological attributes of this species. The rediscovery of P. unicolor draws attention to the biological importance and the lack of protected areas in this region of the Atlantic forest.

ABSTRACT Taxonomic and floristic studies in the state of Rio de Janeiro allowed the rediscovery of Miconia gigantea, an endemic species to the Atlantic Forest, until recently known only from the type specimen, collected over 100 years by A.F.M. Glaziou. We present an amended and detailed description of M. gigantea, providing characteristics of the flowers, fruits and seeds, in addition to illustrations, comments about taxonomic affinities with closely related species, the presently known distribution together with new occurrence records, and the conservation status.
