AbstractThe genus Dietta Sharp, 1876 was previously known in the Neotropics only by D. sharpi Matthews, 1887 from Panama. This paper describes a new subgenus of Dietta, Mesodiettasubgen. nov., occurring in Middle America and northern South America west of the Andes, composed of D. (M.) sharpi Matthews and eight additional new species: D. (M.) esmeraldassp. nov., D. (M.) latidenssp. nov., D. (M.) lobidenssp. nov., D. (M.) mesoamericasp. nov., D. (M.) mexicanussp. nov., D. (M.) puntarenassp. nov., D. (M.) rectispinasp. nov., and D. (M). uncinatasp. nov. Additionally, seven new species of Dietta, subgenus Dietta, are described: D. (D.) argentinensissp. nov., D. (D.) atlanticasp. nov., D. (D.) geraisensissp. nov., D. (D.) guianasp. nov., D. (D.) huanucosp. nov., D. (D.) pauloensissp. nov., and D.(D.) sucumbiossp. nov.

A New Species

Findings pertinent to 11 earthworm species from Venezuela and Brazil are reported. Six of these species are described as new to science, one is re-described and relocated in the genus Andiorrhinus, and new sites of occurrence are reported for four other species. Eight species of oligochaetes were found in the Andes in the state of Mérida, Venezuela: Andiorrhinus (Turedrilus) duranti sp. nov., Andiorrhinus (Meridrilus) timotocuica sp. nov., Andiorrhinus (Meridrilus) torondoy sp. nov., Andiorrhinus (Meridrilus) sp. 1, Andiorrhinus (Quibario) tatuy sp. nov., Andiorrhinus (Meridrilus) kuika (Righi, 1993), Andiorrhinus (Meridrilus) mukuci (Righi, 1993), and Andiorrhinus (Meridrilus) rimeda (Righi & Araujo, 2000). Andiorrhinus (Meridrilus) sp. 1, represented by one specimen only, is possibly a new species. Three other species were collected in Brazil: Andiorrhinus (Amazonidrilus) karinae sp. nov. in the Cerrado bioregion of Mato Grosso state; Andiorrhinus (Amazonidrilus) rodriguezi sp. nov. in the Amazon region in compost, and Andiorrhinus (Amazonidrilus) duseni (Michaelsen, 1918) in the Atlantic Forest, in the states of São Paulo and Paraná, the last species characterized by broad geographical and land use occurrences. The new subgenus Quibario was distinguished by the presence of three pairs of hearts in segments 10, 11, and 12. Keys are also included to differentiate species of subgenera Amazonidrilus and Meridrilus. The implications of these results in the context of ecological interactions, and dispersion of Andiorrhinus species in South America are discussed.

A New Species

A new species of Piper L. (Piperaceae) from the eastern slopes of the Andes in Colombia and Peru, P. callejasii W. Trujillo & M. A. Jaram., is described and illustrated, and morphological comparisons with similar species are discussed. Piper callejasii is distinguished by its stigmas being sessile, rather than on a long style as in four similar species. Its conservation status is suggested to be Endangered.

The diversity of the lichen family Cladoniaceae in the Neotropics is apparently underestimated. A revision of the family for the Flora of the Guianas resulted in the description of 10 species new to science from Northern South America: Cladonia cayennensis; Cladonia flavocrispata; Cladonia isidiifera; Cladonia maasii; Cladonia mollis; Cladonia persphacelata; Cladonia recta; Cladonia rupununii; Cladonia subsphacelata; Cladonia termitarum.

Odontostilbe pulchra, previously considered species inquirenda in Cheirodontinae and doubtfully assigned from the río Orinoco basin, is redescribed with the rediscovery of two syntypes. Originally described to the Island of Trinidad, O. pulchra is widespread in Venezuela, the río Orinoco basin, in smaller coastal drainages of northern South America, in the Lake Valencia system, and río Essequibo basin. A punctual occurrence in the upper rio Negro, near southernmost headwaters of the río Orinoco, extends its distribution to the Amazon basin. Additionally, two new species of Odontostilbe from the río Orinoco basin are described.

Background and aims – As “islands in the sky” of northern South America, the isolated ecosystems of the Pantepui province include a distinct flora with high levels of endemism and which are ancestral areas for many angiosperm lineages. About one fifth of Pantepui angiosperm species are distributed in Poales, a highly diverse angiosperm order.Methods – Recent field trips were carried out on two Brazilian tepuis, by foot and helicopter. Herbarium collections were consulted and compared with the proposed new species. Key results – Four new species of Poales, three Navia Schult. & Schult.f. (Bromeliaceae) and one Paepalanthus Mart. (Eriocaulaceae) were found. Descriptions, illustrations, and distribution maps of the new species, as well as an identification key to Brazilian Navia species, are provided.

The New World Clistopyga isayae species group is revised. Seven species are described as new: C. crassicaudata sp. nov., C. isayae sp. nov., C. kalima sp. nov., C. nigriventris sp. nov., C. panchei sp. nov., C. splendida sp. nov. and C. taironae sp. nov. An illustrated identification key to all species of the group is provided. The Clistopyga isayae species group is composed entirely of previously undescribed species mainly from Andean forests of tropical South America.

A New Species

A new species, Eleocharis endounifascis, is described and illustrated. This species inhabits standing water in disturbed, open habitats, occurring among a mosaic of wet forest, and probably also flourishes in sunny, seasonally inundated wetlands from Belize to southeastern Venezuela and Guyana to Brazil. It was previously confused with Eleocharis interstincta in herbarium collections and floristic works.
