A new species of Bryconops (Ostariophysi: Characiformes: Characidae) from the upper rio Tocantins drainage, Brazil Neotropical Ichthyology
Guedes,Tharles L. O.; Oliveira,Everton F.; Lucinda,Paulo H. F..
ABSTRACT A new species of the genus Bryconops , subgenus Bryconops , is described from the rio Conceição, a tributary to the rio Palma, upper rio Tocantins drainage, Tocantins State, Brazil. The new species is distinguished from all its congeners, except B. humeralis and B. vibex by the color pattern in vivo (dorsal, adipose, and caudal fins entirely orange). The new species is easily distinguished from B. humeralis and B. vibex by the absence of a humeral spot and by the lack of maxillary teeth (vs . presence of a single humeral spot and presence of 1-3 maxillary teeth on both sides). Furthermore, the new species is distinguished from B. vibex by the number of perforated lateral line scales (38-41 vs. 44-46).

A new species of Diaphorocleidus (Monogenea: Ancyrocephalinae) from the gills of Argonectes robertsi (Characiformes) and new records of dactylogyrids parasitic on fishes from the Xingu River, Amazon Basin, Brazil Rev. Bras. Zool.
Moreira,Juliana; Scholz,Tomáš; Luque,José Luis.
ABSTRACT Diaphorocleidus altamirensis sp. nov., parasitic on the gills of Argonectes robertsi Langeani, 1999 from the Xingu River, northern Brazil, is described. The new species differs from its six congeners by the morphology of the male copulatory organ (which comprises a coil of six rings), by the midventral vagina, and by the presence of only one pair of eyespots. It is the first species of Diaphorocleidus Jogunoori, Kritsky & Venkatanarasaiah, 2004 described from hemiodontid fishes. In addition, new host and geographical records of seven species of dactylogyrids found on fish from the Xingu River are reported.

A new species of Falsocis (Coleoptera: Ciidae) from the Atlantic Forest biome with new geographic records and an updated identification key for the species of the genus Rev. Bras. Zool.
Araujo,Lucimar Soares de; Lopes-Andrade,Cristiano.
ABSTRACT Species of Falsocis are very distinct from members of other ciid genera and are relatively uniform morphologically. The genus has been recorded only from well preserved forests in the Neotropical region, from Costa Rica to southern Brazil. We describe Falsocis sooretama sp. nov. based on adult individuals collected at Reserva Biológica de Sooretama (Sooretama, state of Espírito Santo), a conservation unit of the Atlantic Forest biome. Falsocis sooretama sp. nov. is closely related to F. occultus Lopes-Andrade & Lawrence, but differs from it in possessing sparser stout bristles and very minute setae (~0.01 mm) on elytra, and apex of anterior male pronotal plate rounded rather than acute. The male genitalia of F. sooretama sp. nov. and F....

A new species of Farlowella (Siluriformes: Loricariidae) of the F. nattereri species-group from the rio Xingu basin, Mato Grosso, Brazil, with comments on Farlowella jauruensis , a poorly-known species from the upper rio Paraguai basin Neotropical Ichthyology
Ballen,Gustavo A.; Pastana,Murilo N. L.; Peixoto,Luiz A. W..
ABSTRACT A new species of Farlowella is described from eighteen specimens collected in the upper rio Xingu basin, Mato Grosso State, Brazil. The new species is a member of the Farlowella nattereri species-group and can be distinguished from other members of the group, with exception of Farlowella jauruensis , by exhibiting a proportionally shorter snout. The new species is distinguished from F. jauruensis by differences on the cleithrum and plate morphology, by counts of pelvic and caudal-fin rays, and by the color pattern of the snout. The discovery of new lots of F. jauruensis , a species so far known only from the holotype, is also herein reported. This discovery represents a considerable expansion of the geographic distribution and of the number of...

A new species of Machaeriobia Rübsaamen, 1915 (Diptera, Cecidomyiidae) from Brazil Rev. Bras. entomol.
Maia,Valéria Cid; Wilson,Vinícius Abexander Condé; Monteiro,Ricardo Ferreira.
ABSTRACT A new species of Machaeriobia Rübsaamen, 1915 (Diptera: Cecidomyiidae) from Brazil. Machaeriobia Rübsaamen, 1915 is a Neotropical genus, until now known from a single species, M. machaerii (Kieffer, 1913), described from Brazil (State of Santa Catarina). That species induces spherical leaf galls on Machaerium sp. (Fabaceae) and its geographical distribution is still restricted to the type-locality. A new galling species, Machaeriobia gemmae, associated with Machaerium macaense (Fabaceae), is described and illustrated (larva, pupa, male, and female) based on material collected in the Parque Nacional da Serra dos Órgãos (State of Rio de Janeiro, Brazil). The new species is unique for its one or two-segmented palpi, deeply notched aedeagus, pupa with...

A new species of Moenkhausia Eigenmann (Characiformes: Characidae) from the upper rio Machado at Chapada dos Parecis, rio Madeira basin, Brazil Neotropical Ichthyology
Ohara,William M.; Marinho,Manoela M. F..
ABSTRACT A new species of Moenkhausia is described from the upper rio Machado at Chapada dos Parecis, rio Madeira basin, Rondônia State, Brazil. Among congeners, the new species is similar to Moenkhausia chlorophthalma, M. cotinho , M. lineomaculata , M. plumbea, and M. petymbuaba by having dark blotches on the anterior portion of the body scales, which are absent in the remaining species of the genus. The new speciesdiffers from aforementioned species by possessing blue eyes in life, 15-18 branched anal-fin rays, and a well-defined, round caudal-peduncle spot that does not reach the upper and lower margins of the caudal peduncle and does not extend to the tip of the middle caudal-fin rays.
