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 Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.

The new species Notiobia glabrata, N. maxima and N. pseudolimbipennis are described. A key to the 11 Notiobia (s.str.) species known from Brazil, data about the distribution of each species and taxonomical remarks are provided. Notiobia parilis Bates, 1878 is a junior synonym of N. nebrioides Perty, 1830, and Notiobia umbrata Bates, 1882 is a junior synonym of N. jlavicinctus Erichson, 1847. The Brazilian Notiobia species belong to at least three different species groups, each distributed from Brazil over the North-Western part of South America, Central America to Mexico.

The water scavenger beetle genus Tropisternus Solier, 1834, is one of the most common and recognizable taxa of aquatic beetles in the New World. As presently defined, the genus contains 60 species (Hansen 1999, Short & Hebauer 2006) and ranges from northern Canada to the southern tip of South America. The senior author (PJS) conducted a full revision of this taxonomically difficult genus for his PhD dissertation nearly fifty years ago (Spangler 1960). For the next several decades, PJS continued to update, revise, correct, and incorporate new material into this massive work. This paper makes available three new names of Tropisternus in preparation for the eventual publication of this authoritative treatment of the genus. It should be noted for those using the keys given in Spangler (1960) that the interpretation of some of the names proved incorrect following the examination of types; the key should be used with extreme caution particularly for Neotropical taxa.

A parsimony analysis of recently collected species sharing several features such as scalpellate acrostichals, often setae apically on the wing membrane and often strongly extended costa, together with 38 genera show that the collected species can be assigned to Antillocladius S ther, 1981, Compterosmittia S ther, 1981, and one new genus, Litocladius. Nine new species of Antillocladius are described and figured as male imagines: A. calakmulensis, A. herradurus and A. zempoalensis from Mexico; A. venequatoriensis from Ecuador and Venezuela; A. ubatuba from Brazil and Venezuela; and A. biota, A. folius, A. musci, and A. sooretama from Brazil. The female of A. musci, the pupae of A. antecalvus S ther, A. folius, and A. musci, and the larvae of A. folius and A. musci are also described and figured. New records of A. antecalvus S ther from Brazil and Venezuela; of A. arcuatus S ther from Brazil, Mexico and Venezuela; A. pluspilalus S ther from Ecuador and Mexico and of A. zhengi Wang and S ther from Thailand are given. The genus Antillocladius S ther, 1981, originally described from the British West Indies, now includes 15 species from North, Central and South America, Russia, China and Thailand. Keys to all known males, females, pupae and larvae are given. Four new species of Compterosmittia are described and figured as male imagines: C. aberrans from Costa Rica; C. croizati from Brazil and Venezuela; C. pittieri from Venezuela; and C. berui from Brazil. The genus Compterosmittia S ther, 1981, originally described from the British West Indies, now includes 8 to 10 species from North, Central and South America, Australia, Oceania and Southeast Asia. A key to male imagines is given. The new genus, Litocladius, includes a single species, L. mateusi, described as male, female and pupa. The immatures of all three genera are terrestrial or associated with phytotelmata, and notes on their biology and larval habitats are included.

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.

The paper reviews the  most recent findings of the  Rosaceae-feeding Nepticulidae species along with previous records of these tropically specialized leaf-miners in South America and describes three new species: one species on Hesperomeles obtusifolia (Pers.) Lindl (Stigmella circinata Diškus  &  Stonis, sp.  nov.) and two species on Rubus  spp. (S. rubiphagiella Diškus & Stonis, sp. nov. and Ectoedemia morae Diškus & Stonis, sp. nov.); all from the equatorial Andes. Additionally, leaf-mines of the unknown Stigmella taxa feeding on Acaena L., Alchemilla L., Rubus L., Prunus L., and Hesperomeles Lindl are documented. Description of previously unknown females of Stigmella nubimontana Puplesis & Diškus and photographic documentation of leaf-mines of S. nubimontana and S. rubeta Puplesis & Diškus are provided for the first time. The discovered Rosaceae-feeding Nepticulidae exhibit morphological and taxonomical diversity: two new species groups, Stigmella imperatoria and S. circinata, are designated; the latter is also compared with the most similar and probably closely related Holarctic S. hemargyrella and S. sorbi groups.

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.

Loxosceles Heineken & Lowe, 1832 spiders are infamous for their medical importance, but a taxonomic picture of the genus is still far from complete. In this study, the Chilean species of Loxosceles are described and mapped. The males of Loxosceles surca Gertsch, 1967 and L. coquimbo Gertsch, 1967 are described for the first time. Three new species with narrow distributions are described from central and northern Chile: Loxosceles diaguita sp. nov. from the Antofagasta Region, L. pallalla sp. nov. from Coquimbo and L. vallenar sp. nov. from Atacama. The first two species are remarkable in their morphology and do not fit into any of Gertsch’s species groups, suggesting that Chile still harbours an undiscovered phylogenetic diversity of the genus. New distribution records for Loxosceles laeta (Nicolet, 1849) are provided throughout Chile.
