The South American members of the stiletto fly subfamily Agapophytinae (Diptera: Therevidae) comprise three genera that occur predominantly in the western region. Here we describe a newly discovered genus, Sigalopella gen. n., from Chile containing four new species.

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 genus Megarthrus Curtis 1829 with about 139 species described around the world, is the largest of the subfamily Proteininae (Coleoptera: Staphylinidae) (Cuccodoro 2011). Megarthrus is distributed worldwide (Cuccodoro 1999) but it is apparently more diverse in the Holartic region (Navarrete-Heredia et al. 2002). However, the South American fauna is underestimated because many of the collected specimens are not yet described (Cuccodoro 2011). Newton et al. (2005) cited the genus as probable in Colombia because some species are known from Central America and northern South America, but until now, no species has been published from Colombia. Therefore, M. andinus sp. nov. represents the first record of the genus and subfamily for this country.

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.

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).

The South American genus Phantasca Redtenbacher, 1906 (Phasmatodea: Diapheromeridae: Diapheromaerinae) is re-diagnosed and revised at the species level. The precedingly unknown eggs are described for the first time. The genus Pterolibethra Günther, 1940 (type species: P. heteronemia Günther, 1940) is re-synonymised, with Phantasca (syn. nov.) and consequently the two species originally contained, P. heteronemia Günther, 1940 and P. poeciloptera Günther, 1940, are transferred to Phantasca (comb. rev.). P. laeta Conle, Hennemann & Gutierréz, 2011 is not congeneric and is transferred to the genus Jeremiodes Hennemann & Conle, 2007 (Cladomorphinae: Cladomorphini; comb. nov.). Two species are removed from Bacteria Berthold, 1827 and transferred to Phantasca; these are B. quadrilobata Chopard, 1911 and B. montana Redtenbacher, 1906 (comb. nov.). Six new species are described: P. adiposa sp. nov., P. amabile sp. nov., P. femorata sp. nov., P. guianensis sp. nov., P. nigrolineata sp. nov. and P. ruboligata sp. nov. The male and egg of P. quadrilobata (Chopard, 1911) are described and illustrated for the first time. The genus now contains 13 species that are distributed throughout the northern half of South America. A key as well as detailed descriptions and illustrations are presented for all known species.

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.

Passalus Fabricius, 1792 is the largest genus of Passalidae and presents great diversity in South America, mainly in the Amazon region. Currently this complex and heterogeneous genus is subdivided into three subgenera: P. (Pertinax) Kaup, 1869, P. (Mitrorhinus) Kaup, 1871, and P. (Passalus). Herein, two new species of Passalus from the western region of the Brazilian Amazon, a diverse but poorly studied area, are described and illustrated. The new species Passalus (Pertinax) deuterocerus sp. nov. and Passalus (Passalus) cleidecostae sp. nov. are compared with similar species occurring in nearby regions. Also, the diagnostic characters used to define the subgenera and sections of Passalus are summarized.

Sand dollars in the Monophorasteridae Lahille, 1896, form an important part of the South American Cenozoic echinoid fauna. Re-examination of type and other material adds significantly to our knowledge of the morphology and taxonomy of the family, and shows that besides Monophoraster darwini (Desor, 1847), M. duboisi (Cotteau, 1884), Amplaster coloniensis Martínez, 1984, and A. alatus Rossi de Garcia and Levy, 1989, there is a new species, A. ellipticus. We also show that Karlaster Marchesini Santos, 1958, is not a monophorasterid as once thought. A phylogenetic analysis of 24 characters assessed from all species of Monophoraster Lambert and Thiéry, 1921, and Amplaster Martínez, 1984, along with genera of the Mellitidae Stefanini, 1912, produced a single most parsimonious tree. The analysis demonstrates monophyly of mellitids and monophorasterids, and that Iheringiella Berg, 1898, should be excluded from the latter. Although both Monophoraster Lambert and Thiéry, 1921, and Amplaster Martínez, 1984, retain many features of an ancestor in common with the Mellitidae Stefanini, 1912, they also exhibit bizarre morphologies quite different from those of mellitids. The study has also resulted in a clearer picture of the biogeography and biostratigraphy of the Monophorasteridae, and their great significance in the evolution of lunulate sand dollars in the Americas.
