Stenonartonia is a neotropical genus restricted to the forested regions of South America east of the Andes. The genus is revised here and numbers 14 species. Nine new species S. hasyva sp. nov., S. perdita sp. nov., S. cooperi sp. nov., S. guaraya sp. nov., S. rejectoides sp. nov., S. occipitalis sp. nov., S. tanykaju sp. nov., S. hermetica sp. nov., S. grossa sp. nov. are discribed and illustrated. New combination is proposed for S. mimica (Kohl), comb. nov. (from Paranortonia). Lectotype is designated for Nortonia polybioides von Schulthess. A key, along with full descriptions, illustrations of morphological features and distribution maps for all of the species are given.

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.

Review of specimens of Rudgea Salisb. (Rubiaceae, Palicoureeae) has discovered some species new to science and clarified the identity of one previously described taxon. Here we raise R. viburnoides (Cham.) Benth. subsp. megalocarpa Zappi of the western Amazon basin to species status, as R. megalocarpa (Zappi) Bruniera & C. M. Taylor. We also describe 11 new species found variously from lowland to montane elevations in Panama and western South America: R. barbosae C. M. Taylor from scattered locations on sandstone in Colombia; R. campanana C. M. Taylor from central Panama; R. cardenasii C. M. Taylor from the Caribbean area of northwestern Colombia; R. chocoana C. M. Taylor from the Pacific drainage of western Colombia and northwestern Ecuador; R. elegans C. M. Taylor from sandstone formations in the Andes of central Peru; R. homeieri C. M. Taylor from the Andean slopes of central Ecuador; R. inflata C. M. Taylor from the northwestern Amazon basin in Colombia and Brazil; R. retiniphylloides C. M. Taylor from northern to north-central Colombia; R. sanluisensis C. M. Taylor & Cogollo from the lower Río Magdalena valley of northern Colombia; R. suberosa C. M. Taylor & Bruniera from cloud forest and pajonal in the Andes from southern Ecuador through southern Peru; and R. zappiae C. M. Taylor & Bruniera from central western Ecuador.

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

As a part of an assessment of loricariid catfishes inhabiting the Andes of Colombia, specimens belonging to an interesting new species were identified. The new species is described herein, and it is tentatively included in the genus Cordylancistrus. The new species can be easily distinguished among its congeners by the presence of a unique diagnostic character: a fleshy keel or excrescence, black or dark brown, over the posterior tip of supraoccipital. Specimens of the new species were captured in rivers of the Sierra Nevada de Santa Marta and the Sierra de Perijá that drain to the Magdalena River Basin and Caribbean Sea. The occurrence of one species of Cordylancistrus in the Sierra Nevada de Santa Marta could have interesting biogeographic implications for hypotheses related to the geological history of northwestern corner of South America or to the dispersal or vicariance models used to explain biogeographical patterns of related species in Colombia.

A New Species

The Solimões Formation (Eocene-Pliocene) is a well-known geological unit due to the great diversity of crocodylian species. Here we describe a new species of Melanosuchus, M. latrubessei sp. nov., from the Talismã locality, state of Amazonas, from the Upper Miocene of the Solimões Formation (Solimões Basin, Brazil). A new phylogenetic inference focused on Caimaninae is provided and the different evolutionary scenarios involving this new species are discussed. In addition, quantitative morphology studies are carried out and comments regarding the paleoecology aspects of this new species are made. M. latrubessei represents a medium-sized generalist predator, being proportional to the medium-sized M. niger. This new species inhabited the drainages of the Solimões Formation and was ecologically related to other taxa of crocodylians during the proto-Amazon Miocene. The evolutionary advantages of Melanosuchus genus are discussed to better understand the biogeographical occurrence of M. niger in South America, a species which survives to this day in contrast to several other species that became extinct during the Miocene-Pliocene periods. The extinction of the Miocene-Pliocene crocodylian taxa of the Solimões Formation, including Melanosuchus latrubessei, seems to be directly related with the uplift of the northern portions of the Andes, which generated significantly changes in drainages and Amazon paleoenvironments.

A New Species

Bomarea Mirbel (1804: 71; Alstroemeriaceae) includes 122 species (Govaerts 2013) and is divided into four subgenera (Hofreiter & Tillich 2002): Baccata (five species), Bomarea (ca. seventy species), Sphaerine(twelve species) and Wichuraea (eighteen species). Bomarea is distributed from Mexico and the Greater Antilles to southern South America (Gereau 1994). The centre of distribution of the genus is along the Andes from Colombia to Bolivia (Hofreiter 2008).
