A new genus of Neotropical rheophilic catfishes, with four new species (Teleostei: Siluriformes: Pseudopimelodidae) Neotropical Ichthyology
Shibatta,Oscar Akio; Vari,Richard P..
ABSTRACT Rhyacoglanis, a new genus of the South American freshwater catfish family Pseudopimelodidae is described from cis-Andean portions of the continent. Rhyacoglanis is distinguished from other genera of the family by three synapomorphies: presence of a light blotch on the cheek; a connection between the middle of the dark caudal-fin stripe and the dark caudal-peduncle pigmentation; and 30-35 total vertebrae. Species of Rhyacoglanis are rheophilic and strongly associated with rapids and other swift-flowing waters. A phylogenetic analysis based on 41 morphological characters yields a hypothesis of monophyly of the Pseudopimelodidae and Rhyacoglanis. Pimelodus pulcher Boulenger, 1887, from the western Amazon basin is designated as type-species of the new...

A new species of Notalina Mosely, 1936 (Trichoptera: Leptoceridae) from Southeastern Biota Neotropica
Henriques-Oliveira,Ana Lucia; Spies,Márcia Regina; Dumas,Leandro Lourenço.
The Neotropical subgenus Notalina (Neonotalina) Holzenthal, 1986 has ten described species in two species groups: brasiliana, formed by seven species from Southeastern Brazilian and Goiás State; and roraima, represented by three species from the Amazonian and Andes regions. In this paper, a new species of Notalina is described and illustrated from specimens collected in the Mantiqueira mountain range, Southeastern Brazil. The new species belongs to the brasiliana group and is easily recognized by the poorly developed dorsomesal and ventrolateral processes and the pair of mound-like protuberances located mesolaterally on abdominal segment X, and by the robust, rounded mesoventral processes and long digitate mesodorsal processes of the inferior appendages.

Morphological diagnosis and geographic distribution of Atlantic Forest red-rumped mice of the genus Juliomys (Rodentia: Sigmodontinae) Rev. Bras. Zool.
Pavan,Silvia E; Leite,Yuri L. R.
Recognition and identification of red-rumped mice of the genus Juliomys González, 2000 has been a problem among many mammalogists, and specimens of this genus are commonly confused with other Atlantic Forest sigmodontine rodents. Herein we provide an expanded diagnosis for the genus based on the analyses of the three living species of Juliomys, and provide morphological comparisons to the small bodied and bright colored rodents Rhagomys rufescens (Thomas, 1886) and Oligoryzomys flavescens (Waterhouse, 1837), which occur in sympatry with Juliomys spp. in forested areas of southeastern Brazil. These taxa are superficially similar, and are therefore commonly misidentified in the field and museum collections. We also provide morphometric data and a key to the...

New genera and species from the Equatorial Pacific provide phylogenetic insights into deep-sea Polynoidae (Annelida) ArchiMer
Bonifacio, Paulo; Menot, Lenaick.
Polynoidae contains ~900 species within 18 subfamilies, some of them restricted to the deep sea. Macellicephalinae is the most diverse among these deep-sea subfamilies. In the abyssal Equatorial Pacific Ocean, the biodiversity of benthic communities is at stake in the Clarion-Clipperton Fracture Zone (CCFZ) owing to increased industrial interest in polymetallic nodules. The records of polychaetes in this region are scarce. Data gathered during the JPI Oceans cruise SO239 made a significant contribution to fill this gap, with five different localities sampled between 4000 and 5000 m depth. Benthic samples collected using an epibenthic sledge or a remotely operated vehicle resulted in a large collection of polynoids. The aims of this study are as follows:...

New geographical records and key to the species of Eumerus Meigen, 1823 (Diptera, Syrphidae) introduced into the Americas and Hawaii Rev. Bras. entomol.
Garcete-Barrett,Bolívar R.; Morales,Mírian N.; Hauser,Martin; Smit,John T.; González,Luis; López,María Bernarda Ramírez De; Arias,Osmar; Adorno,Marcial; Sormanti,Gerald; Mereles,Adriana.
Abstract Eumerus Meigen, 1823 is a very speciose genus of flower flies from the Eastern Hemisphere. Several reports of introduced species of this genus in the Americas have been recorded since early in the twentieth century, with a present list of six species recorded to date from the Americas and the US territory of Hawaii. In this paper we give new geographical records for the African-native species Eumerus obliquus (Fabricius, 1805), which reflect the expansion of this fly through Brazil and Paraguay along the last twenty years. At the same time, we report a second species from Paraguay, Eumerus aurifrons (Wiedemann, 1824), being this the first Western Hemisphere record for this Asian-native species. We finally provide an identification key to all of...
