There is extensive research of the Ephemeroptera communities taxonomy and ecology in the Andean region of Colombia. However, other regions such as the Orinoquia have been insufficiently studied. From this region, in the Meta department, four species have been registered: Varipes lasiobrachius Lugo-Ortiz & McCafferty, Coryphorus aquilus Peters, Miroculis (Atroari) colombiensis Savage & Peters and Tricorythopsis rondoniensis (Dias, Cruz & Ferreira). The main objective of this study is to report for the first time for this region the species: Mayobaetis ellenae (Mayo), Hydrosmylodon primanus (Eaton), Haplohyphes baritu Domínguez, Camelobaetidus edmundsi Dominique, Mathuriau & Thomas and Nanomis galera Lugo-Ortiz & McCafferty.

The Tomo River runs west to east through the high savannah, known as the 'Altillanura' in eastern Colombia, to flow directly into the Orinoco River. This updated ichthyological checklist was developed by revising and deleting five bibliographic references in combination with the results of an expedition carried out in April 2017 in the lower part of the sub–basin. Here we report 305 species of fish belonging to 183 genera, 45 families and 14 orders. The consolidated checklist includes 69 additional species for Tomo River, of which three species are new records for the Orinoco River basin and eight are new species for Colombia. In addition, we add 578 catalog numbers (10,423 specimens) to the fish collection of the Humboldt Institute (IAvH–P)

The Lacantun Catfish, Lacantunia enigmatica, is reported for the first time in the Usumacinta river basin in Guatemala. Two specimens were collected in the Usumacinta tributaries Río La Pasión and Río Negro, which are characterized by seasonally fast-flowing deep channels and high fluctuations in water-level. We present a map with new records, and a brief description, and images of the specimens collected.

As a result of a SEM study of phytoplankton, the first data on centric diatom species composition in Bolshoye Toko Lake, Yakutia, were obtained. Ten species (Aulacoseira — 5, Cyclotella — 1, Discostella — 1, Handmannia — 1, Pliocaenicus — 1) were found, and one taxon from the genus Pliocaenicus was identified to the genus level. Of these, nine taxa are reported for the first time in the water bodies of the Aldan River basin and Discostella guslyakovyi in Yakutia.

A survey of the ‘Symphyta’ of Colombia is conducted, based on information from literature as well as on examination of over 2,000 specimens from the major Colombian entomological collections. A total of 127 species are recorded from Colombia, representing six families: Argidae (48 species), Tenthredinidae (37) Pergidae (37), Xiphydriidae (3 species), Siricidae (1 species) and Orussidae (1 species). 11 genera and 68 species are new records for Colombia, doubling the number of previously reported species. Heteroperreyia (Pergidae) is recorded for the first time in northern South America. Most records and species are concentrated in the Andean region. Four new species are described: Acrogymnidia catalina Malagón-Aldana, sp. nov., Ptenos amazonicus Malagón-Aldana, sp. nov. (Argidae), Heteroperreyia andina Malagón-Aldana, sp. nov. (Pergidae) and Derecyrta risaraldensis Malagón-Aldana, sp. nov. (Xiphydriidae). The following taxonomic changes are proposed, and lectotypes designated for all these nominal taxa: Dochmioglene suppar (Konow, 1903), comb. n., Plaumanniana parmata (Konow, 1903), comb. n., and Proselandria analis (Fabricius, 1804), comb. n.; Plaumanniana biclinia (Konow, 1899) = Stromboceros marcidus Konow, 1899, syn. n.; Proselandria analis (Fabricius, 1804) = Stromboceros brevispinis Konow, 1908, syn. n., Monophadnus trichiotomus Cameron, 1911, syn. n. and Romaniola amazonica Forsius, 1925, syn. n.

Distribution patterns of most of the 20 Neotropical freshwater turtles belonging to the family Chelidae are usually based on few locality records. We here report on vouchered records of three species of the chelid genus Mesoclemmys in the Brazilian state of Mato Grosso. Presence of M. vanderhaegei is confirmed for the Amazon River Basin, and M. gibba and M. raniceps are recorded in Mato Grosso for the first time.

Aquatic insects in Central Patagonia (Andean region), Argentina, have received poor and fragmentary attention. In this paper we present the first preliminary inventory of Plecoptera and Ephemeroptera taxa for the area and include seasonal records of adult stages. We incorporate a set of environmental features for the sampling sites and biotopes as well as the main characteristics of the phytogeographical and biogeographical areas in which the species were found. Twelve species and eight genera of mayflies and eleven species and five genera of stoneflies are recorded for the first time in Chubut province. The stoneflies Neofulla biloba (Aubert), Alfonsoperla flinti McLellan & Zwick, Austronemoura eudoxiae Froehlich, Chilenoperla semitincta Illies, Neonemura illiesi Zwick and Potamoperla testacea Vera, and the mayflies Andesiops ardua (Lugo-Ortiz & McCafferty), Chaquihua bullocki Navás. And the family Oniscigastridae are new records for Argentina. The genera Americabaetis Kluge, Camelobaetidius Demoulin and Traverella Edmunds are confirmed for first time in the Andean region (Central Patagonia province) and four Plecoptera and two Ephemeroptera species constitute new records for the Patagonian steppe. We also include two new records for Ephemeroptera and Plecoptera for the Santa Cruz province. We reinforce the idea that patagonian aquatic environments have a highly specialized and complex insect fauna which can be correlated with biogeographical aspects but also with a great environmental heterogeneity.

Abstract The genus Thyroptera is composed of small insectivorous bats widely distributed in the Neotropics. Thyroptera lavali is an Amazonian species distributed in lowland rainforests of Peru, Ecuador and Brazil and in the Venezuelan Eastern Llanos. The goal of this study was to document new records of T. lavali for Venezuela and update the geographic distribution of Thyroptera species in that country. Based on specimens deposited in Venezuelan museums, we report the first record of T. lavali for the Guiana Shield and the second record for the Venezuelan Llanos. The external and cranial measurements of the analyzed specimens fall within the range previously reported for T. lavali; likewise, the qualitative characters are similar to what is known for the species. Additionally, derived from a search of records in databases, we report the first specimens of Thyroptera discifera for the Orinoco river basin. We confirm the presence of three species in Venezuela: T. discifera, distributed in the Cordillera de la Costa and Central and Western Llanos; Thryoptera tricolor, occurring in the Andes, Deltaic System and the Guiana Shield and T. lavali, recorded in the Eastern Llanos, Deltaic System and the Guiana Shield.

Moenkhausia hemigrammoides Géry, 1965 was described from Suriname and recently found in the Ariari drainage, part of the Orinoco river basin. Here, we formally report the presence of this species in the Ariari and Inírida drainages of the Guaviare River and present morphological data that complement the original description. Our records of M. hemigrammoides represent the westernmost distribution for this Guianan species in the Amazonas–Orinoco transition zone.
