Two new species of the cricket genus Eidmanacris and a new combination name for a third species (Orthoptera, Grylloidea, Phalangopsidae)

Two new species of the genus Eidmanacris are described (E. bidentata and E. corumbatai) and a new combination name ( E. alboannulata) is assigned for the species Arachnomimus alboannulatus Piza, 1960 (= E. bicornis Mesa & Mello, 1985). Morphological and karyologycal information are provided, and the structure of the genital sclerites is discussed. [KEY WORDS: Orthoptera, Grylloidea, Phalangopsidae, Eidmanacris, cricket, phallic sclerites, chromosomes].

Adenocalymma ubatubensis Assis and Semir, a new species of Bignoniaceae from Ubatuba, Sao Paulo State, Brazil

New species of Hemiodus (ostariophysi, characiformes, hemiodontidae) from the Rio Tocantins, Brazil, with comments on color patterns and tooth shapes within the species and genus

A new hemiodontid species, Hemiodus tocantinensis, is described from the rio Tocantins, Amazon basin, Brazil. It is most closely related to H. ternezi and H. thayeria based on the presence of a dark longitudinal stripe extending from behind the eye or the opercle to the tip of lower caudal fin lobe but is distinguished by the possession of 51 to 58 perforated lateral line scales and an oblique dark blotch on the dorsal fin extending from its anterior distal portion through the middle basal portion of the fin. The evolution of color patterns and tooth shapes present in the Hemiodus species is commented.

Frogs of the genus Paratelmatobius (Anura: Leptodactylidae) with descriptions of two new species

Two new species of Paratelmatobius are described from the Atlantic Forest of Sao Paulo State, southeastern Brazil. The vocalization, tadpole, and natural history of one new species are described. Natural history observations of P. poecilogaster are reported, including the description of a specialized reproductive mode. Diagnoses, measurements, figures, color in life, and distributional data for the species of Paratelmatobius are provided.

A new species of Proceratophrys (Anura: Leptodactylidae) from the Amazon rain forest

A new Proceratophrys from Rondonia, Brazil, is described based on adults and tadpoles. The new form represents a species with eyelids bordered by large, irregularly arranged, warts; postocular swellings absent; snout obtuse with flaring lip in profile; tympanum defined as a depression in the skin; and dorsal surfaces of body and leg bearing high elevated warts. The new species extends the known distribution of the genus to the northwest and represents the first described species of Proceratophrys from the Amazon rain forest. We discuss the species group arrangement in Proceratophrys based on morphology, geographic distribution, and habitat.

New species of Eleutherodactylus (Amphibia: Leptodactylidae) from Guaraquecaba, Atlantic Forest of Brazil

A new species of the leptodactylid frog genus Eleutherodactylus is described from Guaraquecaba, State of Parana, southern Brazil. The new species is characterized by its large size, slightly rugose to rugose dorsal skin texture, robust body, and low number of pulses per call. Descriptions of the advertisement calls of the new species and of E. manezinho, a close related species, are provided, as well as information on natural history.

New species of Phrynohyas from Atlantic rain forest of southeastern Brazil (Anura, Hylidae)

A new species of hylid frog is described from south of the State of São Paulo, southeastern Brazil in Atlantic rain forest. The new species is a member of the genus Phrynohyas and is characterized by snout rounded in dorsal view and nearly truncate in lateral view, small adhesive disks, fingers slightly webbed, nasal bones widely separated, and frontoparietals without medial articulation.

Two new species of Perlidae (Plecoptera) from Mato Grosso State, western Brazil

Adult stoneflies collected in emergence and light traps in central Mato Grosso State are studied. Two new species, Anacroneuria jaciara sp.n. and Macrogynoplax matogrossensis sp.n. are described. Copyright © 2005 Magnolia Press.

Staurogyne rubescens (Acanthaceae), a new species from southeastern Brazil

A new species of Acanthaceae, Staurogyne rubescens, is described and illustrated. It is endemic to the Brazilian moist forests on the eastern range of mountains named Serra do Mar and is thus far known only from the states of Rio de Janeiro and São Paulo. Staurogyne rubescens can be distinguished by its lax terminal racemes, with bracts and bracteoles that are foliaceous, and the flowers that have a pink calyx and red corolla. Staurogyne itatiaiae (Wawra) Leonard also has red flowers and occurs in the highlands of the Atlantic rain forest. The distinguishing characters for these two species are presented in tabular format.

Bryconamericus turiuba, a new species from the upper Rio Paraná system (Ostariophysi: Characiformes)

Bryconamericus turiuba, new species, is described from the upper Rio Paraná system in Brazil. It differs from all congeners in the following combination of characters: 15-20 branched anal-fin rays; four or five scales in a transverse series from the dorsal-fin origin to the lateral line; shallow body (depth 23.6-30.6% of SL); 37-43 perforated lateral line scales; first, third, and fifth or, more rarely, first and fourth outer premaxillary tricuspid teeth projecting anteriorly; two to five tricuspid to pentacuspid maxillary teeth; dentary with three or four tricuspid or pentacuspid large teeth, followed by five to seven smaller conical to tricuspid teeth; a conspicuous dark, vertically elongate humeral spot, extending to below the lateral line; a dark dorsal stripe extending from the supraoccipital spine to the caudal peduncle with a gap at the adipose-fin base; caudal-fin lobes without conspicuous markings, uniformly pigmented along rays; mature males lacking hooks on the pelvic- and anal-fin rays. The new species is compared with the Bryconamericus species described from the basins of the Rio Paraná, Rio Paraguay, Rio São Francisco, and coastal Brazilian rivers. © 2005 by the American Society of Ichthyologists and Herpetologists.

Two new species of Zetzellia Oudemans (Acari: Stigmaeidae) that threaten the concept of genera: Disgeneric marriage?

Two new species of Zetzellia Oudemans, Z. agistzellia sp. n. and Z. quasagistemas sp. n., are described from rubber trees of northwestern São Paulo State, Brazil. Females have clear features of Zetzellia, whereas males resemble Agistemus in some characters. Immatures are also described. The discovery of these species raises some problems concerning generic concepts in Stigmaeidae. Since features of different genera are present in the same species, the authors suggest that the scope of those genera should be reviewed. Copyright © 2005 Magnolia Press.

A new species of Pterodectes Robin, 1877 (Proctophyllodidae: Pterodectinae) from the pale-breasted thrush, Turdus leucomelas (Passeriformes: Turdidae)

A new species of feather mite, Pterodectes fissuratus sp. n., is described from the pale-breasted thrush, Turdus leucomelas Veillot (Passeriformes: Turdidae), in Brazil. This species is easily distinguished by having numerous well-pronounced lacunae and a longitudinal median furrow on prodorsal and hysteronotal shields in both sexes. Copyright © 2005 Magnolia Press.

We describe two new pterodectine feather mites (Analgoidea: Proctophyllodidae) from Brazilian passerines (Passeriformes): Pterodectes amaurochalinus sp. n., from Turdus amaurochalinus Cabanis (Turdidae), and Dolichodectes neotropicus sp. n., collected from Elaenia chiriquensis Lawrence (Tyrannidae). A key to species of the genus Dolichodectes is presented. Copyright © 2006 Magnolia Press.
