During the course of recent fieldwork on Venezuelan aquatic insects, a new species of Hydroscaphidae, Hydroscapha perijaensis Hall & Short sp. n., was discovered and is herein described, representing the first known South American species of the genus. The new species was found in association with rock seepages in both the wet and dry seasons. Locality data is provided, plus dorsal and ventral habitus images of both sexes, along with key characters separating the new taxon from other species within the genus.

A New Species

Hysterionica s.l. (including Neja) comprises ca. 15 species distributed mainly in the grasslands of southern Brazil, Uruguay, central and northern Argentina and Southern Paraguay. Based on field surveys, study of nomenclatural types and other specimens, and review of literature, a new species is proposed here, Hysterionica chamomilloides, endemic of mountainous regions of northern Uruguay, and southwestern Rio Grande do Sul state, Brazil. This work provides a detailed morphological description of the new species, information on its geographic distribution, habitat, phenology, conservation status, and discusses the main differences between H. chamomilloides and the morphologically most similar species. Illustrations, images and a key to the South American species of Hysterionica are also supplied.

The U.S

During the course of an extensive survey of Coleoptera from tropical southern Florida, a specimen of the exclusively Neotropical genus Dryocoetoides was found in flight intercept traps (Atkinson and Peck, 1994; Peck, 1989).  Over the intervening years I have had the opportunity to compare the specimen with material in the U.S. National Museum  and in the S. L. Wood collection (recently transferred to the USNM).   Wood's ( 2007) recent monograph of the South American species of Scolytinae included a key to all the known species of the genus, not only those known from South America.  Based on that key and included descriptions I was able narrow down the possibilities and to borrow selected Schedl types from the Naturhistorisches Museum Wien.  As a result, I have reached the conclusion that this specimen represents an undescribed species.  It is described here to make the name available for a regional monograph of the bark and ambrosia beetles of the southeastern U.S. (Atkinson, in prep.).

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.

A New Species

The spider family Nesticidae includes 233 species in 13 genera and is distributed almost worldwide (World Spider Catalog, 2016). However, the family is still poorly known in the Neotropical Region. The genus Nesticus Thorell, 1869 comprises 132 species and seven subspecies and was described based on N. cellulanus (Clerck, 1757), from Europe (World Spider Catalog, 2016). Meridional South American species of Nesticus were revised by Ott & Lise (2002). More recently, Faleiro & Santos (2011) described a new species from the state of Minas Gerais, Brazil and Torres et al. (2016) a new species from the province of Salta, Argentina. Nowadays, Nesticus is represented by six species in Brazil: Nesticus brasiliensis Brignoli, 1979; Nesticus brignolii Ott & Lise, 2002; Nesticus calilegua Ott & Lise, 2002; Nesticus ivone Faleiro & Santos, 2011; Nesticus potreiro Ott & Lise, 2002 and Nesticus taim Ott & Lise, 2002 (World Spider Catalog 2016).

A new species of the diverse augochlorine bee genus Chlerogella Michener (Halictinae: Augochlorini) is described and figured from southwestern Colombia.  Chlerogella anchicaya Engel, Gonzalez, & Hinojosa-Díaz, new species, is similar to C. agaylei Engel and C. materdonnae Engel, both occurring on the eastern slopes of the Andes in Ecuador.  There are also some similarities with C. eumorpha Engel from the western Andean foothills in northern Ecuador, but differences in rostral length and male terminalia can distinguish these species.  Revised couplets are provided to the South American species of Chlerogella to permit identification of the new species.

Steleops buitrerensis n. sp. is here described and illustrated; it constitutes the 14 th species known in the genus, the 12 th known in the neotropics, and the first in the genus to be recorded in Colombia. The forewings and antennae are sexually dimorphic, and the head pattern of coloration, as well as the genital structure, separates it from the other described species. The location of the types is indicated in the description, and a key is included to separate it from the other South American species. S. pulcher New, previously known only in Mato Grosso, Brazil, is here recorded in Colombia.

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.

The South American species of Desmarestia are revised using morphological features of field sporophytes and reproductive and ontogenetic characters obtained from laboratory culture of gametophytes and young sporophytes. Ten entities including a new species are recognized: D. chordalis, D. confervoides comb.nov., D. distans, D. firma, D. gayana, D. ligulata, D. muelleri sp.nov., D. patagonica, D. peruviana, and D. tropica. Although the taxa were distinguished in part using features of the life history in culture, most field thalli can be identified using morphological characters. A key to the South American species of Desmarestia is provided. Key words: culture study, Desmarestia, Desmarestia confervoides comb.nov., Desmarestia muelleri sp.nov., Phaeophyceae, South America, taxonomy.
