DELIMITAÇÃO ESPECÍFICA NO COMPLEXO CHUSQUEA BACULIFERA SILV. (POACEAE, BAMBUSOIDEAE) COM UTILIZAÇÃO DE MORFOMETRIA

A new species of Rhopalosiphum (Hemiptera, Aphididae) on Chusquea tomentosa (Poaceae, Bambusoideae) from Costa Rica

The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is supported both by the morphological features and by a molecular phylogenetic analysis based on a fragment of the mitochondrial DNA containing the 5' region of the cytochrome c oxid...

Bergbambos and Oldeania, new genera of African bamboos (Poaceae, Bambusoideae)

Two new monotypic genera, Bergbambos and Oldeania are described for African temperate bamboo species in the tribe Arundinarieae, after a comparison of their morphological characteristics with those of similar species from Asia. Morphological differences are supported by their isolated geographical distributions. Molecular evidence does not support the inclusion of these species in related Asian...

De Novo Sequencing and Characterization of the Floral Transcriptome of Dendrocalamus latiflorus (Poaceae: Bambusoideae)

BACKGROUND Transcriptome sequencing can be used to determine gene sequences and transcript abundance in non-model species, and the advent of next-generation sequencing (NGS) technologies has greatly decreased the cost and time required for this process. Transcriptome data are especially desirable in bamboo species, as certain members constitute an economically and culturally important group of ...

Chusquea yungasensis (Bambusoideae, Poaceae): a new species of woody bamboo from South America and the first record of subgenus Rettbergia in Bolivia

A new species of Chusquea subg. Rettbergia is described, illustrated and compared with C. bambusoides. Chusquea yungasensis sp. nov. differs from other species of subg. Rettbergia by its racemose synflorescences. The new species is endemic to Bolivia, and found only in the Yungas ecoregion. Although this subgenus is exclusive to South America, this new species represents the first record of the...
