A New Species

A new species of Passiflora is described from reforested post bauxite-mined area in the National Forest of Saracá- Taquera in the Brazilian state of Pará. The species is illustrated and its affinities with related species are discussed, and a key to the species of supersection Laurifoliae, series Quadrangulares is presented. The series Quadrangulares is composed of four species that constitute a small complex of large-flowered and large-fruited passionflowers with 3–4- angulate-winged stems that occurs naturally in the moist lowlands from Nicaragua to Brazil and French Guiana. However, among the four species of the series, Passiflora trialata is closely related to the new species by the 3-angular stems, the color and shape of sepals and petals, the 3-angular petioles and peduncles, and the single operculum.

ABSTRACT A new species of Paralithoxus is described from the Ajarani River, a small tributary of the Branco River basin, Roraima State, Brazilian Amazon. The genus Paralithoxus comprises species described from the Essequibo drainage in Guyana, Approuague and Maroni in French Guiana, Suriname River in Surinam, and more recently, from Jari and Amapá rivers, in Brazil. Despite occurring in a rock-bottomed fast-flowing stream as the other species of Paralithoxus, this is the first species of the genus collected at 900 m altitude, in the Serra da Mocidade highlands, an isolated and poorly accessible small mountain chain at the southern border of the Guiana Shield. The new species is distinguished from its congeners by having truncate teeth, color pattern with green spots on dark olive-brown background, alternating dark and light blotches on fins and by the pelvic fin being as long as or longer than the pectoral fin. Sex dimorphism of the species is described. Comments on morphology and osteology are provided and compared with congeners.

A New Species

SummaryA new species of nematode, from the family Spiruridae, is described using parasites from the esophageal mucosa of Proechimys roberti (Rodentia: Echimyidae), which were obtained during a fauna survey in the Tapirapé-Aquirí National Forest, Carajás Reserve, Brazil, Eastern Brazilian Amazon. The helminthes were collected from the esophagus, fixed and processed for light microscopy. Spirura carajaensis n. sp. differs from other species in the genus because it has a left spicule with a well-developed sheath, which is leaf-shaped and covers the terminal half of the spicule. Males and females have a small appendix on the caudal end. This structure has not been reported before for this genus. The present study reports the first record of parasitism by Spirura in rodents of the genus Proechimys in Brazil and in the Amazon biome.

A New Species

The Passiflora subgenus Astrophea has its greatest diversity in the Amazon Rainforest, which is the largest biodiversity reserve in the world. During a taxonomic revision of Brazilian Astrophea species, a new species was discovered from the municipality of São Gabriel da Cachoeira in the state of Amazonas. Morphological and palynological analysis, as well as comparisons with related species, confirmed that the specimen represents a new species to science belonging to the Passiflora subgenus Astrophea, section Pseudoastrophea. Passiflora lorenziana is the name given to the new Amazonian species, which is herein described, illustrated and compared to related species.

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.
