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.

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.

The aquatic snakes of the genus Helicops are widely distributed throughout northern South America but understudied concerning many aspects, including morphological traits and distribution. The most recent publication that provided an identification key to all species of Helicops is more than 50 years old. The key is of limited value today since it included taxa no longer recognized and lacks 8 of the 19 species currently recognized. There never was a publication trying to summarize the distribution information of all species of Helicops. Most of the knowledge on these species is distributed over many small publications, like observation notes. Here we present point distribution maps, an identification key and comments on identification for all species in this genus based on the results of a comprehensive literature review of over 300 scientific publications and own examinations. Our examinations comprise 190 specimens of 10 of the 19 currently recognized species and one Helicops sp. Furthermore, we report range extensions for the species H. angulatus, H. danieli, H. infrataeniatus, H. leopardinus, H. pastazae and H. polylepis.

Recent collecting efforts in the Neotropics have led to the discovery of numerous new species and lineages of aquatic beetles. Here, three new genera are described to accommodate fifteen new species of water scavenger beetles of the subfamily Acidocerinae from northern South America:Crucisternumgen. n.forC.escalerasp. n.(Venezuela),C.ouboterisp. n.(Guyana, French Guiana, Suriname, Venezuela),C.queneyisp. n.(French Guiana),C.sinuatussp. n.(Brazil),C.toboganensissp. n.(Venezuela),C.vanessaesp. n.(Suriname), andC.xingusp. n.(Brazil);Katasophistesgen. n. forK.charynaesp. n.(Peru),K.cuzcosp. n.(Peru),K.meridasp. n.(Venezuela) andK.superficialissp. n.(Ecuador); andNanosaphesgen. n.forN.castaneussp. n.(Brazil),N.hesperussp. n.(Suriname),N.punctatussp. n.(Guyana), andN.tricolorsp. n.(Guyana, Suriname). It was also found that the monotypic Neotropical endemic genusDieroxenusSpangler, 1979,syn. n.is congeneric withChasmogenusSharp, 1882 resulting in the single new combinationChasmogenuscremnobates(Spangler, 1979),comb. n..Katasophistesmeridasp. n.is known exclusively from seepage habitats, while the remaining taxa described herein are primarily associated with the margins of densely forested streams. Diagnoses, illustrations, distribution maps, and habitat summaries are provided for all new genera and species. A key to the genera of Acidocerinae of the New World is provided.

A new species, Varronia teguorum Fern. Alonso & J.I.M. Melo (Cordiaceae), from central Colombia is described. This new taxon is compared morphologically with V. subtruncata and V. bullata, the species with which it is most easily confused. An identification key for the Varronia species with globose inflorescences from Colombia/northern South America is presented.

A taxonomic synopsis of Virola (Myristicaceae) is presented for Mesoamerica. Fourteen species are recognised, amongst them six are described and published as new, based on morphology: V. allenii D.Santam. & Aguilar, sp. nov. from Costa Rica, V. otobifolia D.Santam., sp. nov. from Panama and V. amistadensis D.Santam., sp. nov., V. chrysocarpa D.Santam. & Aguilar, sp. nov., V. fosteri D.Santam., sp. nov. and V. montana D.Santam., sp. nov. from both Costa Rica and Panama. Additionally, a lectotype is designated for V. koschnyi, accompanied by an epitype in view of the fragmentary material. Finally, we recognise V. laevigata and V. nobilis as morphologically distinct species, though these are frequently considered synonymys of V. guatemalensis and V. surinamensis, respectively. Of the fourteen accepted species, twelve of them are endemic to Mesoamerica, while the remaining two species (V. elongata and V. sebifera) extend into South America. Illustrations, species diagnoses and distribution maps for each species are provided, as is an identification key to all species.

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.
