A new species of Boehlkea (Characiformes: Characidae: Stevardiinae) from the rio Japurá, Amazon basin, Brazil Neotropical Ichthyology
Soares,Isabel M.; Bertaco,Vinicius A.; Ito,Priscila Madoka M.; Zuanon,Jansen.
ABSTRACT A new species of Boehlkea is described from rio Japurá, Amazon basin. The new species differs from B. fredcochui by the presence of a vertically elongate humeral spot (vs. absence), complete lateral line (vs. incomplete), four rows of scales below lateral line (vs. three), and lower number of branched anal-fin rays (17-21 vs. 22-25), and from B. orcesi by the higher number of maxillary teeth (13-14 vs. 5-12), greater head length (27.9-29.9% vs. 24.3-27.5% of SL), and by the color pattern (basal half of dorsal-fin, distal portion of pelvic-fin, lower caudal-fin lobe and anal-fin with black chromatophores vs. absence of black chromatophores in the fins).

Description of a new species of Ituglanis (Siluriformes: Trichomycteridae) from Serra dos Carajás, rio Tocantins basin Neotropical Ichthyology
Wosiacki,Wolmar B.; Dutra,Guilherme M.; Mendonça,Marina B.
A new species of Ituglanis is described from the rio Tocantins basin, State of Pará, Brazil. Ituglanis ina, new species, is distinguished from its congeners by the presence of a dark vertical bar over the base of the caudal-fin rays (vs. no bars over caudal-fin base); and by the presence of a middle trunk line of tiny neuromasts extending along the flank until the vertical through the dorsal fin, or near the caudal-fin base (vs. no middle trunk line of tiny neuromasts). Ituglanis ina can be further distinguished by a combination of characters related to color pattern and morphology. Comments on the relationship between Ituglanis species are presented.

Developmental biology, polymorphism and ecological aspects of Stiretrus decemguttatus (Hemiptera, Pentatomidae), an important predator of cassidine beetles Rev. Bras. entomol.
Paleari,Lucia Maria.
Developmental biology, polymorphism and ecological aspects of Stiretrus decemguttatus (Hemiptera, Pentatomidae), an important predator of cassidine beetles. Stiretrus decemguttatus is an important predator of two species of cassidine beetles, Botanochara sedecimpustulata (Fabricius, 1781) and Zatrephina lineata (Fabricius, 1787) (Coleoptera, Cassidinae), on the Marajó Island, Brazil. It attacks individuals in all development stages, but preys preferentially on late-instar larvae. Its life cycle in the laboratory was 43.70 ± 1.09 days, with an egg incubation period of six days and duration from nymph and adult stages of 16.31 ± 0.11 and 22.10 ± 1.67 days, respectively. The duration of one generation (T) was 12.65 days and the intrinsic population growth...

New record of Amphisbaena fuliginosa (Squamata, Amphisbaenidae) for the Cerrado Biome, in an area of extensive cattle ranching Biota Neotropica
Lemos,Frederico Gemesio; Facure,Kátia Gomes.
Samples of Amphisbaena fuliginosa from the Cerrado biome are scarce and additional data are needed to clarify the geographic distribution and patterns of differentiation of this species. During field works at a cattle farm in the south of the state of Goiás, Central Brazil, we found an adult individual of A. fuliginosa. Our specimen represents the southernmost record for the species, extending its distribution 150 km. The color is similar to that described for other specimens from Goiás state, corroborating the uniform pattern observed for Cerrado populations. We suggest that the fossorial habits of A. fuliginosa may allow its occurrence in anthropogenic habitats by offering protection against the changes in natural vegetation.

New species of Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the eastern Amazon, Pará, Brazil Neotropical Ichthyology
Vieira,Lorena S.; Netto-Ferreira,André L..
ABSTRACT A new species of Pyrrhulina is described based on 60 specimens from tributaries of the rio Amazonas: rio Anapu, rio Capim, rio Guamá and rio Xingu, and coastal drainages in the state of Pará, Brazil. The new species differs from all congeners by having the primary stripe (the horizontal stripe of dark pigmentation extending posteriorly from the snout) terminating at the distal edge of the opercle. In all other species of Pyrrhulina, the primary stripe is either restricted to the snout or continues beyond the head (i.e. at least the anteriormost four scales of the lateral line series).

Redescription of Astyanax erythropterus (Holmberg, 1891) (Teleostei: Characiformes: Characidae) from La Plata basin in Argentina Neotropical Ichthyology
Soneira,Paula; Casciotta,Jorge; Almirón,Adriana; Ciotek,Liliana; Giorgis,Pablo.
Astyanax erythropterus (Holmberg, 1891) originally described on the basis of one juvenile, is redescribed herein based on juveniles and adults from the type-localiy. The species differs from its congeners by the combination of 11-13 transverse rows scales above lateral line and 8-10 rows below lateral line; 49-54 perforated scales in the lateral series; iii-v,38-42 anal-fin rays, and dorsal, anal and caudal fins vermilion red in juveniles. The vermilion red coloration of unpaired fins in juveniles of Astyanax is only known in A. correntinus.

Redescription of Astyanax goyacensis Eigenmann, 1908 (Ostariophysi: Characiformes: Characidae) Neotropical Ichthyology
Garutti,Valdener; Langeani,Francisco.
Astyanax goyacensis Eigenmann, 1908 is redescribed based on the holotype and 25 topotypes. The species belongs to the A. bimaculatus species complex, sharing with those species a black, horizontally ovate, humeral spot (the most conspicuous feature of this complex), two diffuse vertical brown bars in the humeral area (the first through humeral spot and the second 2-3 scales behind), and black medium caudal-fin rays. Furthermore, A. goyacensis possesses a black stripe extending along midlateral body portion, more conspicuous in alcohol preserved specimens. These characteristics allow its inclusion in the putative "black lateral stripe" sub-group of A. bimaculatus species complex. From the species of this complex it differs by the black lateral stripe shape,...

Reinstatement of Euarche rudipalpa (Polychaeta: Acoetidae), with remarks on morphology and body pigmentation Rev. Bras. Zool.
Salazar-Vallejo,Sergio I.; Rizzo,Alexandra E.; Fukuda,Marcelo V..
Eupanthalis rudipalpa Amaral & Nonato, 1984 was described based on three incomplete, colorless specimens and has not been reported since its original description; the epithet rudipalpa means "hirsute palps", a characteristic that separates it from other congeneric species. Eupanthalis McIntosh, 1876 and Euarche Ehlers, 1887, and their respective type species, E. kinbergi McIntosh, 1876 and E. tubifex Ehlers, 1887, were considered synonyms (E. rudipalpa as a junior synonym of E. tubifex, a cosmopolitan species) by some authors, because both have sessile eyes and two or three antennae. Nonetheless, these two genera are, in fact, distinct. Their type species can clearly be separated using some prostomial features. We provide an emended diagnosis of...
