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.

Two New Species

A synopsis of the South American species of Sangaris Dalman, 1823 is presented. Sangaris luteonotata Monné & Monné sp. nov. and S. ordinale Monné & Monné sp. nov. are described from Ecuador. Sangaris luctuosa (Pascoe, 1859) comb. nov. and Sangaris obtusicarinata (Zajciw, 1962) comb. nov. are transferred from Colobothea Lepeletier & Audinet-Serville, 1825. New distributional data are given for S. trifasciata Melzer, 1928, S. zikani Melzer, 1931, and S. luctuosa (Pascoe, 1859). A key to the South American species is provided.

World Distribution

The araneid genus Larinia Simon currently includes 56 species, eleven of them with New World distribution (World Spider Catalog, 2016). North American species of the genus were revised first time by Levi (1975) and South American species by Harrod et al. (1991). According to these authors there are four species known from subtropical South America (Larinia bivittata Keyserling 1885; L. montecarlo (Levi, 1988); L. t-notata (Tullgren, 1905); L. tucuman Harrod, Levi & Leibensperger, 1991) and also four species known from tropical South America (L. ambo Harrod, Levi & Leibensperger, 1991; L. directa (Hentz, 1847); L. lampa Harrod, Levi & Leibensperger, 1991; L. neblina Harrod, Levi & Leibensperger, 1991). According to Buckup et al. (2010) a total of 209 species of Araneidae are recorded for state of Rio Grande do Sul, including the three species L. bivittata, L. montecarlo and L. t-notata.

The weevil tribe Dryophthorini is reported in Peru for the first time. Two species from Satipo, Junin, Stenommatus chabooae Legalov n. sp. and Stenommatus sokolovi Legalov n. sp., are herein described. Stenommatus chabooae Legalov n. sp. is characterized by having the elytral interstriae narrower than striae width; pronotum coarsely punctate; large, narrow aedeagus, weakly curved at apex, with a large basal sclerite of the endophallus. Stenommatus sokolovi is characterized by having the elytral interstriae as wide as striae width; pronotum finely punctate; small, wide aedeagus, rounded at apex and endophallus lacking sclerites. A key to the South American species of the genus Stenommatus is given.

First Time

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.

During the analysis of European and American herbaria collections for a taxonomic review of the Brazilian species of Gurania, two new South American species were found.  Gurania jeffreyi occurs in Ecuador and Colombia and Gurania calathina is found only in Colombia. Descriptions and illustrations of the new species are presented with comments on affinities and differences between them and related species.

Agave sisalana Perrine, a native species from Yucatán Peninsula (Mexico), is recorded for the first time for Colombia. It is morphologically related to Agave fourcroydes Lem. and Agave pax Giraldo-Cañas, but clearly differs from it in various vegetative and reproductive characteristics, which are given. Thus, a total of ten species of Agave are currently known in South America, seven are native and three are naturalized. A key for the South American species is included.

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.

A New Species

Three species of the genus Allocosa Banks, 1900 from southern South America are redescribed: Allocosa alticeps (Mello-Leitão, 1944), A. brasiliensis (Petrunkevitch, 1910) and A. senex (Mello-Leitão, 1945). The female of A. senex is described for the first time and the species is revalidated. A new species, A. marindia sp. nov. from southern Uruguay and southern Brazil is described. The new species is distinguished by the flattened terminal apophysis of the male bulb and the conspicuous pointed projections on the posterior margin of the female epigynum. The species inhabits in sandy estuarine and oceanic coasts with psammophile vegetation.
