Porroglossum marcojimeneziorum, a new species of subtribe Pleurothallidinae, was discovered in Zamora Chinchipe province (South-East Ecuador) which is described here, including information about its phenology and ecology. Porroglossum marcojimeneziorum is compared with its most similar species, P. hirtzii, from which it differs by producing smaller flowers; the shortly-pubescent, triangular-ovate, obtuse lateral sepals and the blade of the lip obovate transversely expanded. Key words: Porroglossum marcojimeneziorum, Porroglossum hirtzii, Zamora Chinchipe

Begonia margaretiana, a new species of Begonia sect. Pritzelia from Rio de Janeiro state, Brazil is described. Begonia margaretiana is morphologically similar to Begonia paulensis, with which it is compared. The new species grow in hygrophilous Atlantic Forest in the south of Rio de Janeiro state, Brazil. Description, comparisons with a morphologically similar species, etymology, taxonomic comments, illustrations, a map, and the conservation status of the new species are provided.

A new species of Epidendrum from Peru, Epidendrum curimarcense, is described, illustrated and compared with the similar species Epidendrum ampelospathum. The new finding represents an important record for the flora associated with Polylepis forests of central Peru. The species has stems produced from a middle internode of the previous cane-like stem, a spathe, an elongate peduncle with several similar spaced bracts, flowers opening in succession, petals narrower than the sepals, a 3-lobed lip which is bicallose with rounded sub-equal lobes, and 4 obovoid, laterally compressed pollinia. Key Words / Palabras clave: Andean orchids, central Peru, Epidendrum, Junín, orquídeas andinas, Polylepis

Trisetella pachycaudata, a new species in the subtribe Pleurothallidinae, was discovered in the Zamora Chinchipe province of southeast Ecuador, and it is described here. Trisetella pachycaudata is compared with the most similar species (and others with which it has been confused in cultivation), T. triglochin, T. strumosa, and T. vittata. It differs from them in the flowers with a much thicker apex of the sepaline tails (the thickest in the genus), and the petals expanded at the labellar margin, with the cuspidate apices erose on the upper margin and entire at the lower margin. Key words / Palabras clave: Trisetella strumosa, Trisetella triglochin, Trisetella vittata, Zamora Chinchipe

AbstractBulbothrix johannis is described as new to science. The species is morphologically similar to the South American Bulbothrix pseudofungicola Benatti & Marcelli but has wider lobes, laminal ciliate isidia which frequently develop into phyllidia, larger cilia and rhizines, and longer ascospores. This epiphytic species occurs fairly frequently in the cloud forests and montane thickets on Réunion Island (Mascarene archipelago). The comparison of B. johannis with morphologically and chemically similar species shows that several different African taxa are currently grouped under the widely used but problematic name B. suffixa (Stirt.) Hale.

Pleurothallis minutilabia, a species unique in subsection Macrophyllae-Fasciculatae because of the minute, highly reduced lip, is described and compared to the most similar species in the subsection. It is also compared morphologically to Pleurothallis kaynagata from section Abortivae, to which P. minutilabia is not related, but which also possesses a highly reduced lip. The morphology of the flower of P. minutilabia is discussed briefly in relation to possible pollination mechanisms. The distribution, restricted to Zamora Chinchipe, southern Ecuador, and the conservation status are addressed. Key words / Palabras clave: cloud forest, Ecuador, labellar morphology, Pleurothallis, pollination

A new species of Sphaerodoridae (Annelida: Polychaeta),Sphaerodoropsis solissp. nov., is described from the Challenger Plateau in the Tasman Sea, south-west Pacific. It is the third species of the genus with ventral macrotubercles and is further characterized by the lack of dorsal papillae and the specific arrangement pattern of ventral papillae. A character indicating sexual dimorphism, that has been observed in three morphologically similar species,S. arctowskyensisHartmann-Schröder & Rosenfeldt, 1988,S. bisphaeroserialis(Hartmann-Schröder, 1974c), andS. garciaalvareziMoreira, Cacabelos & Troncoso, 2004, is confirmed forS. solissp. nov. BesidesS. solissp. nov.,S. arctowskyensisandS. parva(Ehlers, 1913) are newly recorded from the Challenger Plateau and the East Campbell Plateau in the south-west Pacific. An updated key for the genusSphaerodoropsisis provided.

Lepanthes vere-aurum, a new species of the orchid subtribe Pleurothallidinae, discovered in Zamora Chinchipe province, southeast Ecuador, is described here. We compare L. vere-aurum to L. brenneri, the only similar species, from which it differs in having larger leaves and longer inflorescences. Also, L. vere-aurum has an obovate, concave, long-acuminate dorsal sepal and a concave appendix with a pubescent crest underneath and with a long, pubescent apex,versus a flat, triangular-ovate, acuminate dorsal sepal and a smaller appendix with a ciliate apex in L. brenneri. Some information about its phenology and ecology is additionally provided. Key Words: Cordillera del Cóndor, endangered orchid, Epidendroideae, Lepanthes brenneri, new orchid species
