Serpophaga hypoleuca P.L. Sclater & Salvin, 1866, is a bird species distributed in northern South America, where it mainly inhabits shrubs on river islands and occasionally large river shores. Its distribution is not well known in Colombia where current records show the species present south of the Amazonas department and locally in Arauca and Vichada. We present a new locality in Colombia along the Guaviare River, in San José del Guaviare, which expands the known distribution of this species in Colombia, filling an information gap for the Guaviare region.

First Time

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.

Based on material deposited in a Colombian entomological collection, new records from northern South America (Colombia and Venezuela) are presented for eight species of Gerridae (Insecta, Hemiptera, Heteroptera). The species belong to the genera Brachymetra Mayr, 1865 (Charmatometrinae); Limnogonus Stål, 1868; Neogerris Matsumura, 1913 (Gerrinae, Gerrini); Tachygerris Drake, 1957 (Gerrinae, Tachygerrini); Metrobates Uhler, 1871 (Trepobatinae, Metrobatini); and Telmatometra Bergroth, 1908 (Trepobatinae, Trepobatini). Photographs of the habitus of adults and distribution maps are also presented for each species.

In northern South America, an extensive tropical lowland runs 5,000 km from the Atlantic coast to the foot of the Andes. The slope is gentle until about 500 m where the eastern Andes rise abruptly. The lowland supports Amazonia, which is the most extensive tract of tropical rainforest on the planet. Most of its boundaries are well defined, but the boundary between Amazonia and the forest of the eastern slopes of the Andes has not been clearly defined. To determine for avifauna whether Amazonia is restricted to the lowland of northern South America or whether it also extends up into the eastern slopes of the Andes, different types of data were used. The results indicate that Amazonia may be restricted to the lowland that extends from the Atlantic coast to the foot of the Andes, up to about 500 m. Consequently, the number of bird species strictly endemic to Amazonia would be 290. Comparison with the distribution of vegetation on the eastern slopes of the Andes also suggests that Amazonia as a biome may be restricted to the lowland that extends from the Atlantic coast to the foot of the Andes, up to about 500 m.

Micrurus isozonus is a triadal coralsnake occurring in northern Venezuela, eastern Colombia, southern Guyana, and in the extreme northern Brazil. In this paper we firstly publish vouchers to Brazil, and report additional records from three localities in the mountainous region of Taião and Apiaú, state of Roraima. We also extend its known range to the Trans-Andean region in the Atlantic coast of northern South America, municipality of Cartagena at the Caribbean coast of Colombia. Additionally, we present meristic and morphometric data, including the species sintypes.

Elmidae is one of the most diverse families of aquatic beetles, with more than 1500 species in 151 genera. The Neotropical genus Portelmis formerly comprised five species known from Central and northern South America, divided into two species groups. Three new Brazilian species from the nevermanni group are described and illustrated here: Portelmis vanini sp. nov., Portelmis krolowi sp. nov. and Portelmis fusariae sp. nov. New species records for the North, Central-West and Southeast of Brazil are presented. We also provide first SEM images and an updated key for Portelmis species.

The genus Bactrophora Westwood, 1842 comprises only two species known from Central America and northern South America, with a notable scarcity of collected specimens. Herein, we provide the first records of the presence of this genus in Brazil. These new records, based on entomological collection data and photographic records, extend the known distribution of Bactrophora dominans Westwood, 1842 to include the Brazilian Amazonian region. Both records emphasize the importance of natural history collections and the significance of the iNaturalist web-based application as an instrumental tool in this discovery.

Subduction ground motions in northern South America are about a factor of 2 smaller than the ground motions for similar events in other regions. Nevertheless, historical and recent large-interface and intermediate-depth slab earthquakes of moment magnitudes Mw = 7.8 (Ecuador, 2016) and 7.2 (Colombia, 2012) evidenced the vast potential damage that vulnerable populations close to earthquake epicenters could experience. This article proposes a new empirical ground-motion prediction model for subduction events in northern South America, a regionalization of the global AG2020 ground-motion prediction equations. An updated ground-motion database curated by the Colombian Geological Survey is employed. It comprises recordings from earthquakes associated with the subduction of the Nazca plate gathered by the National Strong Motion Network in Colombia and by the Institute of Geophysics at Escuela Politécnica Nacional in Ecuador. The regional terms of our model are estimated with 539 records from 60 subduction events in Colombia and Ecuador with epicenters in the range of −0.6° to 7.6°N and 75.5° to 79.6°W, with Mw≥4.5, hypocentral depth range of 4 ≤  Zhypo ≤ 210 km, for distances up to 350 km. The model includes forearc and backarc terms to account for larger attenuation at backarc sites for slab events and site categorization based on natural period. The proposed model corrects the median AG2020 global model to better account for the larger attenuation of local ground motions and includes a partially non-ergodic variance model.
