Aosa sigmoidea, a new species of the genus Aosa (Loasaceae) from Brazil

A new species of Aosa (Loasaceae) is described from Minas Gerais in Brazil. A. sigmoidea clearly is a close relative of Aosa rostrata from the same area. The plant differs in being very much taller (2 m in A. sigmoidea in comparsion to 0.05–0.30 m in A. rostrata ) and in having capsules with a clavate inferior portion which is 7–10 mm long while the inferior capsule portion in A. rostrata is hemisphaerical and only 1.5–2 mm in diameter.     

Andreadoxa flava (Rutaceae, Cuspariinae): a new genus and species from Bahia, Brazil

Andreadoxa flava is distinguished from all other genera of the neotropical subtribe Cuspariinae by the combination of a cupular calyx, yellow, free petals narrowed at base, two glandular-punctate anthers joined by their based appendages, five apically subglobose and glandular staminodes, a smooth papery testa, and conduplicate, plicate cotyledons. It is one of 10 monospecific genera of the subtribe and one of 17 species of this subtribe endemic to the coastal forests of Bahia.     

Four new species of genus Cordia (Cordiaceae, Boraginales) from Brazil

We describe four new species of Cordia (Cordiaceae) from Brazil: Cordia fusca, C. glabrifolia, C. restingae, and C. tarodae. These are illustrated, and data on habitat, phenology, and distribution are provided.     

Thymocarpus cannoides (Marantaceae), a new genus and species from Venezuela and Brazil

Thymocarpus, apparently most closely related to Calathea, is described and illustrated. Its sole species, T. cannoides, has been collected in lowlands of eastern Venezuela and western Brazil.     

Hybanthopsis, a new genus of Violaceae from Eastern Brazil

A new genus of Violaceae is described from Brazil.Hybanthopsis Paula-Souza, with a single species (H. bahiensis Paula-Souza), is endemic to caatingas of Bahia, Brazil, and is morphologically most similar toHybanthus, from which it differs by the fruit morphology and especially its peculiar seeds.

Um novo gênero brasileiro de Violaceae é descrito.Hybanthopsis Paula-Souza, com uma única espécie (H. bahiensis Paula-Souza), é endêmico de caatingas do Estado da Bahia, e é morfologicamente mais similar aHybanthus, do qual difere pela morfologia do fruto e especialmente por suas sementes peculiares.

     

A remarkable new genus and a new species of chewing louse (Phthiraptera,Ischnocera, Philopteridae) from Brazil

A new genus of chewing louse as Bobdalgleishia, and its type species Bobdalgleishia stephanophallus sp. n. (Phthiraptera) belonging to the Brueelia-complex (Ischnocera: Philopteridae) are described. Adults of the new species are fully described, illustrated and compared morphologically with the type species of Motmotnirmus Mey & Barker, 2014, which is its closest relative. The type host of Bobdalgleishia stephanophallus is a subspecies of the great jacamar Jacamerops aureus ridgwayi Todd, 1943, an endemic Amazonian bird distributed in northern Brazil, and the type locality is the State of Pará. Bobdalgleishia is a remarkable genus with unique morphological and chaetotaxic characters which readily separate it from other members of the Brueelia-complex, in particular by having the first two marginal temporal and ocular setae very long.     

Trilepis tenuis (Cyperaceae: Trilepideae), a new species from Rio de Janeiro, southeastern Brazil

Trilepis tenuis is described from the state of Rio de Janeiro, southeastern Brazil. It differs from the other four species ofTrilepis in its delicate habit and combined features of the contraligules and fructifications.     

Intestinal helminths of freshwater stingrays in southeastern Peru, and a new genus and two new species of cestode

Helminths of the spiral intestine of neotropical freshwater stingrays (Potamotrygonidae) were examined in Peru for the first time. The stingrays examined for helminths included Paratrygon aiereba, Potamotrygon motoro, and Potamotrygon cf. castexi. Present in P. aiereba were the cestodes Nandocestus guariticus (Marques, Brooks, and Lasso, 2001) n. gen. n. comb., Rhinebothrium copianullum n. sp., Rhinebothrium sp. 1, Rhinebothroides sp., Potamotrygonocestus cf. fitzgeraldae, and 1 species each of Cucullanus and Rhabdochona. Nandocestus n. gen. is erected to house N. guariticus, which is formally transferred from Anindobothrium Marques, Brooks, and Lasso, 2001. The new genus is unique among phyllobothriids in its possession of circummedullary vitelline follicles and a submarginal genital pore, in combination with bothridia with a single apical sucker and marginal bothridial loculi. The helminths of P. motoro included the cestodes Paraoncomegas araya, Acanthobothrium peruviense n. sp., Acanthobothrium cf. ramiroi, Rhinebothrium sp. 1, Rhinebothroides sp. 1, Potamotrygonocestus sp., the nematode Brevimulticaecum regoi, a species of Cucullanus, and a species of the digenean superfamily Diplostomoidea. The helminths of P. cf. castexi included the cestodes P. araya, N. guariticus n. gen. n. comb., Acanthobothrium cf. peruviense, Potamotrygonocestus sp., Rhinebothrium sp. 1, Rhinebothroides sp. 2, the nematode species Echinocephalus daileyi and B. regoi, 1 species each of Cucullanus, Rhabdochona, and Procamallanus, and a species of the digenean superfamily Hemiuroidea. All taxa were examined via light microscopy; the cestode taxa were also examined using scanning electron microscopy. Each helminth species recorded in this study is a first report from Peru. The study suggests that the diversity and host specificity of the cestodes in potamotrygonid stingrays may be greater than previously thought. The known numbers of genera and species of tetraphyllidean cestodes parasitizing neotropical freshwater stingrays are now 6 and 22, respectively.
