The South American species of the water beetle genus Hydraena Kugelann, 1794, are revised, based on the study and databasing of 2,418 specimens. New collection records are provided for 14 previously described species, and 54 new species are described. The South American fauna now comprises 82 species, only three of which are also known to be present outside of South America. Two new species groups are described, and several new species complexes are diagnosed. A neotype is designated for Hydraena paraguayensis Janssens. High resolution digital images of the holotypes of new species are presented, asare images of the primary types of 18 previously described species (online versions in color). Geographic distributions of all South American Hydraena are mapped. Male genitalia, representative female terminal abdominal segments and representative spermathecae are illustrated.

In this contribution we present updates on the taxonomy and morphology of the South American species of Amitermes. Two new species are described: Amitermes bandeirai, sp. n., from Brazil, and Amitermes lilloi, sp. n., from Argentina. Amitermes nordestinus is a junior synonym of Amitermes aporema. The imago of A. aporema is described for the first time. Detailed comparative gut anatomy of the eight species is presented for the first time. The geographic distribution of Amitermes in South America is expanded and the distribution patterns of some species are discussed.

The South American species of Pseudocanthon Bates, 1887 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini) are reviewed. In this work, 10 valid species and two subspecies are recognized for the genus. Among these species, five are recorded in South America, including three new species: P. perplexus (LeConte, 1847), P. xanthurus (Blanchard, 1847), P. vazdemelloi new species, P. pantanensis new species, and P. chaquensis new species. A lectotype is designated for P. xanthurus (Blanchard, 1847). In this revision, each species is analyzed as follows: a detailed literature review, an identification key for the South American species, a diagnosis, descriptions, illustrations of key morphological characters, list of examined material, and geographic distribution.

Chalcis Fabricius (Hymenoptera: Chalcididae) currently includes over 50 described species, most of them from temperate regions of the Northern Hemisphere. Prior to the present study, only Chalcis pilicauda (Cameron) had been recorded from South America. The examination of specimens collected in Argentina, southern Bolivia, Brazil, Ecuador, Paraguay, and Uruguay allowed the description of six new species: C. boi Saguiah & Tavares sp. nov., C. danunciae Saguiah & Tavares sp. nov., C. intervalensis Saguiah & Tavares sp. nov., C. periotoi Saguiah & Tavares sp. nov., C. quechua Saguiah & Tavares sp. nov., and C. winstonae Saguiah & Tavares sp. nov. Chalcis pilicauda is redescribed, and C. ornatifrons (Cameron) stat. rev. is removed from synonym under C. pilicauda and re-established. An identification key for South American species is presented.

Crossopalpus is a rather diverse genus of tachydromiine flies, but regionally the genus is nowhere very speciose. Knowledge on the South American Crossopalpus before this paper included two described species from Andean related habitats, with several biomes from the eastern part of the continent being completely unexplored. Herein, we describe four new species of Crossopalpus from eastern South America, namely: C. albivertex sp. nov., C. aliceae sp. nov., C. goliathus sp. nov., and C. xanthogaster sp. nov. New diagnoses and high quality photographs are made available for C. armipes (Bezzi, 1909) and C. pennescens (Melander, 1918), including some characters used for the first time to distinguish South American species. We provide a key for identification of the six South American species, discussion about the position of Crossopalpus in Drapetidini, and some biogeographical insights including preferred habitats and seasonality of the South American species. We discuss the apparent loss of tergite 10 in females of Drapetidini, introducing a reinterpretation where the sclerite may be present in some genera of the tribe, but fused to the cerci and/or sternite 10.

Six new species of Paracloeodes are described: four from Brazil (P. assu, P. atroari, P. peri and P. waimiri), one from Argentina (P. yuto) and one from Bolivia (P. pacawara), based on nymphs. Three other species from South America: P. binodulus, P. eurybranchus and P. ibicui are revised. A cladistic analysis including most of the South American species of Paracloeodes and the monotypic genus Iguaira is presented. A key for all South American species is included.
