Adiantum camptorachis (Pteridaceae), a New Species from South America with Notes on the Taxonomy of Related Species from the Southern Cone and Bolivia

As a part of an assessment of loricariid catfishes inhabiting the Andes of Colombia, specimens belonging to an interesting new species were identified. The new species is described herein, and it is tentatively included in the genus Cordylancistrus. The new species can be easily distinguished among its congeners by the presence of a unique diagnostic character: a fleshy keel or excrescence, black or dark brown, over the posterior tip of supraoccipital. Specimens of the new species were captured in rivers of the Sierra Nevada de Santa Marta and the Sierra de Perijá that drain to the Magdalena River Basin and Caribbean Sea. The occurrence of one species of Cordylancistrus in the Sierra Nevada de Santa Marta could have interesting biogeographic implications for hypotheses related to the geological history of northwestern corner of South America or to the dispersal or vicariance models used to explain biogeographical patterns of related species in Colombia.

A new legume species, Weberbauerella chilensis, from the Andean foothills in the Tarapacá region in Chile, is described and illustrated. This species represents the first record of the genus in Chile and the Southern Cone of South America and is the third species described for the genus. Weberbauerella chilensis resembles W. brongnartioides from Peru, but differs primarily in its smaller size, fewer leaflets and habitat conditions.

A New Species

The spider genus Oxyopes Latreille occurs throughout the world, but is insufficiently known in South America and the Caribbean. In this study, three apparently related species of this genus are reported from the region. Oxyopes salticus Hentz, 1845 is redescribed and illustrated, and extreme variation in colour pattern and in female genitalia is reported within this species. Oxyopes m-fasciatus Piza, 1938 and Oxyopes nigrolineatus Mello-Leitão, 1941 are both considered junior synonyms of O. salticus. The material examined in this study, together with information from the literature, show this species is widely distributed throughout the continental Americas and the Caribbean. Oxyopes crewi Bryant, 1948 is redescribed and illustrated, and its geographic distribution is extended to Bahamas, Cuba, Dominican Republic, Jamaica, and Saint Kitts. A new species, Oxyopes incantatus sp. nov., is described and illustrated for the first time based on specimens from the Galápagos Islands.

In this paper, we describe the first species with abbreviated larval development for Guatemala,Macrobrachium cemainov. sp. This is a freshwater prawn of medium size, with large second pereiopods in relation to body size, compared to related species in Mexico and South America.Macrobrachium vicconiRomán, Ortega & Mejía, 2000, reported from Chiapas, Mexico, is the closest species geographically. However,M. vicconiis different fromMacrobrachium cemainov. sp. in the scaphocerite proportion, length of the first pereiopods and in the proportions of the second pereiopod, i.e., ratios of carpus/merus, carpus/propodus, palm/dactylus, propodus/dactylus and the rostrum ornamentation.

Fungal Genus

Species of the fungal genus Arthrinium (Sordariomycetes, Amphisphaeriales, Apiosporaceae) are often found on bamboo in Asia. They are endophytes, saprobes and important plant pathogens. The genus Arthrinium currently contains 92 species and is widely distributed in North and South America, Europe, Africa, Asia and Oceania. In this study, a new species, Arthrinium bambusicola sp. nov., is described and illustrated. The new taxon is characterised by oval to broadly or irregularly round, medium brown, multi-guttulate to roughened, granular conidia, with finely pale slits in the outer edges. Arthrinium bambusicola can be distinguished from the closest related species A. gutiae by its conidial characteristics. Phylogenetic analyses of a four-locus dataset (ITS, LSU, TEF1, TUB2) confirm that A. bambusicola is a distinct new species.

A new species of Petalomium Cross 1965 (Acari: Heterostigmatina: Neopygmephoridae) is described. This mite was found associated (phoresy) with workers of an ant, Neoponera verenae (Forel 1922) (Hymenoptera: Formicidae), in several localities in the state of Bahia, Northeastern Brazil. This is the first record of the genus in South America. A closely related species, Petalomium gottrauxi Mahunka 1977, is redescribed based on the paratype and specimens from Crimea. New recorded morphological structures are described and discussed.

Coleoptera Tenebrionidae

Callyntra is a genus of tenebrionid beetles endemic to the Southern Cone region of South America, with 23 species occurring in Chile and one shared with Argentina. The recent descriptions of new species were commonly based on the male genitalia structure, underestimating the utility of the female genitalia for this purpose. Analysis of the ovipositor structure of a series of females assigned to Callyntra carbonaria from the Bío-Bío and Araucanía in Southern Chile, have resulted in the discovery of a new species, Callyntra femina sp. nov., which was corroborated through molecular analysis using COI and 16S gene fragments. The phylogenetic analysis recovered C. femina as sister to a clade composed of C. rossi, C. carbonaria and C. riverai, being genetically more similar to C. rossi.

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.
