Sixteen species of Peruvian Dysmorphocerinae (Cantharidae) are described as new (regions in parenthesis): Hyponotum macrocephalum sp. nov. (Huanuco); H. succhabamba sp. nov. (Cajamarca); Plectonotum altomayo sp. nov. (Amazonas); P. amazonas sp. nov. (Amazonas); P. bicoloricolle sp. nov. (Huanuco); P. carpish sp. nov. (Huanuco); P. celendin sp. nov. (Cajamarca); P. costae sp. nov. (Cajamarca); P. huariaca sp. nov. (Pasco and Huanuco); P. huascaran sp. nov. (Ancash); P. huertoae sp. nov. (Cajamarca); P. leymebamba sp. nov. (Amazonas); P. luteipes sp. nov. (Amazonas); P. oxapampa sp. nov. (Pasco); P. rubrithorax sp. nov. (Huanuco); P. shipasbamba sp. nov. (Amazonas). A lectotype is designated for Plectonotum longissimum (Pic, 1927) for which a redescription is provided. Plectonotum ruficolle Wittmer, 1988, homonym of Plectonotum ruficolle Pic, 1926, is renamed as Plectonotum neoruficolle nom. nov. New keys are proposed in English and Spanish for the identification of the Peruvian species of the genus Plectonotum and the South American species of the genus Hyponotum Wittmer, together with macrophotographs of habitus, details of pronotum, male genitalia and a cartographic representation of their distribution.

Three New Species

The South American species of the genera Askola and Hagenulopsis are revised. Three new species of Askola from Brazil are described based on male imagos. Askola emmerichi sp. nov. and A. paprockii sp. nov. present spotted wings, but differ in general coloration and details of genitalia; Askola cipoensis sp. nov. is easily distinguished because the male eyes being widely separated on meson of head. Three new species of Hagenulopsis are also described: H. lipeo (from Argentina and Bolivia) and H. zunigae (from Colombia), both described from imagos and nymphs, can be recognized by details of coloration and male genitalia. H. esmeralda sp. nov. from Ecuador, described from imagos, shows a distinct male genitalia and translucent male abdomen. A key to species for the the male and female imagos of Askola and Hagenulopsis species is provided.

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

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.

Three New Species

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 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.

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.

AbstractThe South American species of Oplachantha Rondani are reviewed and a key to them presented. New species are atricalx, Peru; pallida, Colombia; albihirta, Colombia; fuscipes, Venezuela; divisa, Ecuador; and atriceps, Peru. New synonymies are (iubata Enderlein) = pulchella (Williston) and (tristis Enderlein) = cincticornis Enderlein. Allognosta Barbiellinii Bezzi, Hoplacantha nigerrima Lindner, and Antissops Bezzii Lindner, sometimes referred to this genus or to Berismyia, belong to an as yet undetermined genus.
