A new record of giant squid Architeuthis sp. (Cephalopoda: Oegopsida) in Brazilian waters Rev. Bras. Zool.
Martins,Rodrigo Silvestre; Perez,José Angel Alvarez.
A carcass of a giant squid Architeuthis sp. was found afloat off Southern Brazil (28°05'S, 45°35'W) on 29 August 1999. The specimen was a mature female of 116 cm mantle length and had arms incomplete and tentacles missing. The specimen was morphologically similar to those previously described for the Southwest Atlantic, but a few peculiarities were found on the shape of the fins, head and the cross-section and length of ventral arms. Spermatophores were found embedded within the skin of the left ventral arm, at around 60 cm from the mouth, and could be traced to the core of the arm, radiating nearly four centimeters from the point of entry. This was the third record of Architeuthis in Brazilian waters and the eighth in Southwest Atlantic when the specimen...

A new species of Argiope (Araneae: Araneidae) from Brazil Rev. Bras. Zool.
Motta,Paulo César; Levi,Herbert W..
A new species of Argiope Audouin, 1826 is described. This is a large Argiope from South America and is found mainly in "cerrado" vegetation in central Brazil. Argiope legionis sp. nov. is most similar to A. ericae LEVI, 2004 but differs from this species by the coloration and epigynum in the female and the median apophysis and embolus of the palpus in the male palp.

A new species of Goeldia (Araneae: Titanoecidae) with notes on its natural history Rev. Bras. Zool.
Almeida-Silva,Lina M.; Brescovit,Antonio D.; Dias,Sidclay Calaça.
A new species of Goeldia Keyserling, 1891 is described. Goeldia is the only genus of Titanoecidae with species in the Neotropical region and includes eight species diagnosed by the presence of a patellar process in the male palp. The new species, Goeldia zyngierae sp. nov., was found living inside the Casa de Pedra cave, Ribeira, Itabaiana, Sergipe, Brazil. Goeldia zyngierae sp. nov. is diagnosed by the tegular process with a small constriction near the base of the dorsal part and by a distal narrowing, more visible in the dorsal side of the patellar process of the male palp. The female epigynum shows a pair of sinuous depressions and a large mid field that does not close the copulatory openings as in Goeldia luteipes Keyserling, 1878. The vulva presents a...

Abundância e distribuição de Aeglidae (Crustacea: Anomura) em função do uso da terra na bacia hidrográfica do Rio Jacutinga, Rio Grande do Sul, Brasil Rev. Bras. Zool.
Trevisan,André; Hepp,Luiz Ubiratan; Santos,Sandro.
This study investigated the influence of land use and occupation on the density and distribution of aeglids in the hydrographic basin of the Jacutinga river (northern state of Rio Grande do Sul, Brazil). Sampling was carried out during the summer and winter of 2004, at 12 sites distributed in river spring, agriculture, grazing, and urban areas. Animals were collected using a Surber sampler. An analysis of variance (ANOVA) was conducted to evaluate differences in the density of species in each land use and sampling period. Biological data were classified using cluster analysis (Euclidian distance; UPGMA). A total of 226 aeglids were captured, including 167 (78.89%) specimens of Aegla platensis Schmitt, 1942 and 59 (26.11%) specimens of A. singularis...

An overview of Brazilian mammalogy: trends, biases and future directions Rev. Bras. Zool.
Brito,Daniel; Oliveira,Leonardo C.; Oprea,Monik; Mello,Marco A. R..
Mammals are among the most charismatic and well-studied organisms, and Brazil harbors the largest mammal diversity of the world. The Brazilian Society of Mammalogy was established in 1985, and since 2001 it organizes the Brazilian Congress of Mammalogy. We used the proceedings of all three editions of this congress together with papers indexed in Web of Science and Scielo to evaluate trends in Brazilian mammalogy. All contributions were categorized according to mammalian order, biome, topic of research and state of authors' affiliation. Our results show that mammalian orders with higher species richness receive more attention, but the ranking is different between abstracts and papers. Higher species richness did not translate into more attention for more...

Análise comparativa da dieta de quatro espécies de cucos (Aves: Cuculidae), no sul do Brasil Rev. Bras. Zool.
Repenning,Márcio; Basso,Helena C. de P.; Rossoni,Jonas R.; Krügel,Marilise M.; Fontana,Carla S..
We studied stomachs contents of 50 specimens of four common cuckoo species (Cuculidae) from southern Brazil: Guira guira (Gmelin, 1788) (n = 21), Coccyzus melacoryphus (Vieillot, 1817) (n = 8), Crotophaga ani (Linnaeus, 1758) (n = 11), and Piaya cayana (Linnaeus, 1766) (n = 10). We measured stomach volume and prey were identified and quantified based in their dimensions. The size of the prey was associated with bill width and body mass. Diet items were analyzed and identified to the lowest possible taxonomic level, based on literature, scientific collection data, and specialists. The diet of the four species was composed by 100% animal species, with invertebrate dominance. Only in G. guira stomachs the presence of vertebrates was observed more than once...

Aspectos biológicos e morfológicos de Leucanella viridescens (Lepidoptera: Saturniidae: Hemileucinae) Rev. Bras. Zool.
Specht,Alexandre; Corseuil,Elio; Benedetti,Augusto J.; Poletto,Graziela; Formentini,Aline C..
The goal of this work was to describe aspects of the biology and morphology of Leucanella viridescens (Walker, 1855), a polyphytophagous species that is a pest to several crops of economical interest and whose larvae may cause erucism. Biological parameters were obtained under controlled conditions: temperature of 25 ± 1ºC, relative humidity of 70 ± 10%, and a 14 h photophase. Morphological and behavioral aspects were analyzed in each developmental phase. The larval stage had six instars, with an average growth rate of 1.396. A high degree of polyphytophagy was observed, including over 49 host plant species belonging to 25 families, especially Leguminosae, Solanaceae and Salicaceae. The considerable chromatic variability of the adults obtained from the...

Avaliação dos problemas enfrentados no manejo do caramujo gigante africano Achatina fulica (Gastropoda: Pulmonata) no Brasil Rev. Bras. Zool.
Colley,Eduardo; Fischer,Marta Luciane.
The giant African snail Achatina fulica Bowdich, 1822 was introduced into Paraná, Brazil, in the 1980s. Since then, it has spread across the country, despite its known invasive status on a global scale. The main objective of this study was to assess the problems faced in the management of the giant African snail. To accomplish that, we gathered and analyzed information available on the internet, scientific databases, field studies, as well as interviews and consultations with official agencies, NGOs, museums, the scientific community and people that coexist with the species. Despite the fact that extensive information has been generated regarding A. fulica (1,340 articles, 65 summaries in national annals, 40,700 pages on the internet), essential to promote...

Behavioral repertory of Trichodactylus panoplus (Crustacea: Trichodactylidae) under laboratory conditions Rev. Bras. Zool.
Zimmermann,Bianca L.; Aued,Anaide W.; Machado,Stela; Manfio,Daiara; Scarton,Laura P.; Santos,Sandro.
This work describes the behavioral repertory of Trichodactylus panoplus von Martens, 1869, based on the animals' diel activity and the possible substrate preference under laboratory experiments. Three experimental replicates were carried out, each using six animals (three males and three females). There were four periods of observation a day, with a total of 864 observation sessions and 144 hours of experiments. A total of 15 behavioral acts divided into five categories were recorded: feeding, exploration of the environment, immobility, social interaction, and self-grooming. The obtained results suggest that T. panoplus has greater activity during the night (p < 0.05), yet without showing an activity peak. In addition, the acceptance of food does not...

Biologia reprodutiva de Echinometra lucunter (Echinodermata: Echinoidea) na Praia da Costa, Vila Velha, Espírito Santo Rev. Bras. Zool.
Mariante,Fátima L. F.; Lemos,Gabriela B.; Eutrópio,Frederico J.; Gomes,Levy C..
Echinometra lucunter Linnaeus, 1758 is a tropical sea urchin with strong bioerosive potential. Consequently, this species has great ecological importance. The species occurs in high densities along the Brazilian coast, particularly in the south and southeast. The objective of this work was to evaluate both the effects of annual seasonality and the lunar cycle on the reproduction of E. lucunter. Individuals were sampled monthly for a period of one year and during four complete lunar cycles. The gonadosomatic index (GI) was calculated to determine the annual and monthly reproductive peaks based on the lunar phase. The sex ratio (male:female) was 1:1.04, without significant difference in sexual proportion. The GI was significantly higher for males than for...

Braga cigarra comb. nov. for Philostomella cigarra (Crustacea: Isopoda: Cymothoidae) with a redescription of the species based on specimens from Galeocharax kneri, a freshwater fish of Minas Gerais State, Brazil Rev. Bras. Zool.
Thatcher,Vernon E.; Oliveira,Antonio A. N. de; Garcia,Adriana M..
Specimens of a cymothoid isopod from a freshwater fish of Minas Gerais State were studied. These were found to be morphologically comparable to Philostomella cigarra Szidat &amp; Schubart, 1960, except for having multilaminate pleopods which is the distinguishing characteristic of the genus Braga Schiödte &amp; Meinert, 1881. The first pleopod is bilaminate while the second is quadrilaminate. Pleopods three to five are trilaminate. It is herein proposed that the generic name Philostomella Szidat &amp; Schubart, 1960, should be considered invalid and that the species P. cigarra should be transferred to Braga. Braga now contains eight species, including B. cigarra comb. nov., all from South American freshwater fishes. The principal difference...

Brazilian species of Onychophora with notes on their taxonomy and distribution Rev. Bras. Zool.
Sampaio-Costa,Cristiano; Chagas-Junior,Amazonas; Baptista,Renner L. C..
A revision of the currently known distribution of Onychophora (velvet worms) in Brazil is presented. Twenty-four morphospecies (half of them undescribed) belonging to four genera of the Peripatidae (Peripatus Guilding, 1826, Epiperipatus Clark, 1913, Macroperipatus Clark, 1913 and Oroperipatus Cockerell, 1908) are recorded. This high number of "unidentified" morphospecies is due to three major reasons: the poor quality of the characters used in species-level identification, the inadequate specimen conservation in ethanol, and, in most cases, the lack of additional specimens for analysis of intra- and inter-specific variation. The morphological characters currently used to separate Peripatidae species present a large degree of variation and may not be...

Campylorhamphus procurvoides successor (Aves: Dendrocolaptidae) is a junior synonym of Campylorhamphus trochilirostris notabilis Rev. Bras. Zool.
Portes,Carlos Eduardo; Aleixo,Alexandre.
The taxonomy of the genus Campylorhamphus Bertoni, 1901 is still uncertain, with many inconsistent evolutionary patterns implied by current taxonomy. A re-analysis of the type-series of Campylorhamphus procurvoides successor Todd, 1948 revealed that the holotype is indistinguishable from Campylorhamphus trochilirostris notabilis Zimmer, 1934, while the paratypes belonged either to the latter taxon or to a second already named taxon (Campylorhamphus trochilirostris snethlageae Zimmer, 1934), and a third and yet undescribed taxon allied to Campylorhamphus procurvoides. Here, we present statistical analyses of morphological data supporting the synonymization of C. p. successor into C. t. notabilis, the name with priority. Our findings resolve the...

Capture sequence and relative abundance of bats during surveys Rev. Bras. Zool.
Esbérard,Carlos E. L..
It is expected that rare species will be gradually added to biodiversity surveys over time and that complete inventories will include rare species. The objective in the present work is to test whether the capture sequence of species during a bat survey is related to species abundance. Species with capture rates lower than 0.01x10-3 captures/hour-net were considered rare. At Ilha da Gipóia, rare species accounted for 22.22% of the total and, at Rio das Pedras Reserve, they represented 30.00%. The existence of a negative relationship between the relative abundance and the first night of capture of each species for the Ilha da Gipóia and the high significance level for the accumulation curve at both localities suggest that the documentation of a large number...

Caste differences in Pseudopolybia compressa (Hymenoptera: Vespidae: Polistinae) Rev. Bras. Zool.
Pizarro,Laura Chavarría; Noll,Fernando B.; Mateus,Sidnei.
Studies of morphological caste syndromes in the tribe Epiponini help us to understand the evolution of social behavior in insects. Few studies have integrated morphological syndromes of various species from the same or distinct genera. We studied morphological differences between castes from three colonies of Pseudopolybia compressa de Saussure, 1854, in order to relate their caste syndrome with those of other species in the genus. We took eight morphometric measures and females were classified in relation to ovarian development and spermathecal contents. Females of Colony 1 (C1) present a higher distinction between castes than females of Colonies 2 and 3 (C2 and C3), and, in general, queens of the three colonies are larger than workers in some measures...
