New Diagnosis

Hoplonannus McAtee & Maloch, 1925 comprises three species described from Central America. Females of all these species are known only from brachypterous specimens. This paper describes the first South American species of the genus, Hoplonannus australis sp. nov. The new species differs from its congeners, in females, by the submacroptery, presence of ocelli and a basal bulge in the seventh sternite; in males, it differs by the presence of a process in the eighth tergite and the right paramere bifurcate apically, with branches subparallel. These traits entail a new diagnosis for the genus.

A New Species

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.

Polyamia (Polyamia) choromorica sp. n., representing the first record of the genus Polyamia DeLong from South America, is described and illustrated. Previously described species of Polyamia DeLong appear to be restricted to North America. Color illustrations of Polyamia (Copolyamia) caperata (Ball), Polyamia (Copolyamia) similaris DeLong & Davidson and Polyamia (Polyamia) weedi Van Duzee are also provided for comparison.

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.

A New Species

Rheotanytarsus is a speciose genus, currently composed by more than 100 nominal species distributed worldwide, 19 are known from the Neotropical region, four from South America and only one is registered for Peru. In the present study, a new species is described and illustrated based on males collected in the Peruvian Andes. In addition, the key to the South American species is updated and a distribution map of them is provided. Rheotanytarsus amaru sp. n. is easily distinguished from the congeneric species by the dark general coloration and the hypopygial morphology.

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.

The genus Epipompilus occurs throughout the Neotropical region, United States, Australia and New Zealand. South American members of this genus appear to have evolved separately from the others Pompilidae for a considerably time. E. aztecus was initially recorded only for Mexico and Central America. Our record expands the distribution of E. aztecus to South America, bringing new perspectives to the biogeography of spider wasps.

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

Abstract—Antiphytum charruasorum, a new endemic species from western Uruguay, is described. This is the only South American species in the genus with white corolla and an infra-medial cicatrix on the ventral face of the eremocarp, both features shared with the North American species of Antiphytum, in sharp contrast with the blue corolla and the basal cicatrix at the end of a stipe-like prolongation that characterizes all South American species in the genus. Antiphytum charruasorum increases the diversity of the genus in South America, as well as the endemism and distribution range into Uruguay. Moreover, this new species adds novel features in Antiphytum such as the irregularly dichasial inflorescences, the hirsute faucal appendages, the eremocarps with a tissue plug from the gynobase, and the habitat where the species has been reported.

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.
