| A short illustrated biography of Marta Erps Breuer (1902-1977), designer and lab technician at the University of São Paulo (Universidade de São Paulo), and a former Bauhaus student, is presented. Additionally, twenty fine China ink drawings of the male terminalia of twenty species of Neotropical Drosophila, made by her between October 4th, 1951, and March 24th, 1959, and currently deposited in the archives of the Department of Genetics and Evolutionary Biology of the Institute of Biosciences of the University of São Paulo (Departamento de Genética e Biologia Evolutiva, Instituto de Biociências, Universidade de São Paulo), São Paulo, State of São Paulo, Brazil, are included. All illustrated species but one are members of one of the following seven groups of... |

| ABSTRACT Lygophis flavifrenatus Cope, 1862 is a terrestrial dispsadid distributed in subtropical Brazil, Paraguay, Uruguay, and Argentina. Herein, we present data on sexual dimorphism and reproductive biology of this very poorly studied species. A total of 108 specimens (55 females, 50 males, three hatchlings with unidentified sex) from Brazilian states of Rio Grande do Sul, Santa Catarina and Mato Grosso do Sul were analyzed. Sexual dimorphism by size, body dimensions (tail length, head length, head width) and a number of ventral and subcaudal scales is not well marked in the species. Mature females attain the greater size and have a higher number of ventral scales than mature males. Mature males, in turn, presented longer tail, longer and wider head and... |

| ABSTRACT The South American genus Heteropyge Silvestri, 1897 is revised, accommodating now six accepted species. Adults of the poorly known species Heteropyge araguayensis (Schubart, 1947) are described for the first time from near-topotypic material collected near the Araguaia River, state of Mato Grosso, Brazil. In addition, based on recent samplings and on material from Schubart’s collection, H. bidens (Schubart, 1945) is removed from the synonymy of H. cayennophilus (Silvestri, 1897) and revalidated. Both species show significant differences concerning the gonopods and male leg-pair 1. New records and additional data for H. bidens and H. cayennophilus are provided, as well as an updated checklist of the species belonging to Heteropyge. |

| Brazilian fauna of drosophilids has been researched in various ecosystems, but those in mangrove forests remain overlooked in Brazil and elsewhere. The present study attempts to characterise the assemblages of drosophilids of this environment, based on 28 collections taken in three mangrove areas in Santa Catarina Island, southern Brazil. The three mangroves surveyed were different in their surroundings, which varied from highly urbanised areas to conservation areas with natural vegetation. Overall, 69 species were collected, and no remarkable difference was detected in species composition and abundances or in the richness, evenness and heterogeneity between sites. The species abundance distribution observed fitted to a theoretical lognormal distribution... |

| Four new species of the spider genus Cybaeodamus Mello-Leitão, 1938 are described and illustrated: C. meridionalis sp. nov. from Brazil and Argentina, C. taim sp. nov. from Brazil, Argentina and Uruguay, C. brescoviti sp. nov. and C. tocantins sp. nov. from setentrional region of Brazil. For the species Cybaeodamus enigmaticus (Mello-Leitão, 1939), C. lycosoides (Nicolet, 1849) and C. ornatus Mello-Leitão, 1938, new illustrations based on the examination of the types are presented. The species Cybaeodamus nigrovittatus Mello-Leitão, 1941 which the holotype is an immature specimen, C. pallidus (Mello-Leitão, 1943) which the type was not located, C. rastellifer (Mello-Leitão, 1940) and C. scottae Mello-Leitão, 1941, both described upon juvenile specimens,... |

| Abstract In the state of Mato Grosso do Sul, which is composed by four macroregions, Cerrado, Chaco, Atlantic Forest and Pantanal, there are 39 species and 24 genera of Tachinidae based on the literature. The subfamily Tachininae, with 15 species occurring in the State, has the highest representativeness, while the other subfamilies, Exoristinae, Phasiinae, and Dexiinae, with respectively 14, 7 and 3 species. |

| ABSTRACT We investigated the fish fauna response to different environmental conditions of urban (three) and rural (seven) streams through biomass/abundance curves and W index of environmental stress. Negative values of W indicate some level of stress, while positive values suggest environments with lower stress. Dissolved oxygen, marginal erosion (both left and right margins), mesohabitat diversity, and percentage of canopy cover were measured to characterize the 10 streams analysed around Maringá city, Southern Brazil. Fish were sampled by electrofishing, then identified and weighed. Results showed negative values of W to the urban streams and positive to the rural. Urban streams showed a tendency to have assemblages of fish with lower biomass and greater... |

| In this study we describe three new litter inhabiting species of Mesabolivar González-Sponga, 1998 from nine urban forest remnants in the metropolitan region of the city of São Paulo, Brazil: M. forceps, M. mairyara and M. cavicelatus. In three of these remnants, we conduced a three year sampling using pitfall traps. Mesabolivar forceps sp. nov. was the most abundant pholcid (n=273 adults), always present in the samples, but with highest numbers in spring and summer. Mesabolivar mairyara sp. nov. was the second most abundant species (n=32), but the majority of individuals were collected in March 2001. Only three individuals of M. cavicelatus sp. nov. were collected. |

| The freshwater prawns of the genus Macrobrachium Spence Bate, 1868 are widely distributed in rivers of tropical and subtropical regions and represent an interesting group with controversial taxonomy. The morphological characters traditionally used to separate species have shown a high intraspecific variation. Doubts about the status of M. birai Lobão, Melo & Fernandes, 1986, M. holthuisi Genofre & Lobão, 1978 and M. petronioi Melo, Lobão & Fernandes, 1986 have been arisen due to the high resemblance of the former two species with M. olfersi (Wiegmann, 1836), and the latter one with M. potiuna (Müller, 1880). Therefore, we performed a detailed morphological analysis of these species, including new characters not usually used in the... |

| ABSTRACT Eclipta dendensis Nascimento & Santos Silva, 2017 (nomen nudum) is validated. The Neotropical Eclipta Bates, 1873, together with five other genera, composes a generic complex in Rhinotragini, which were previously allocated in Ommata White, 1855. In Brazil, many species of Eclipta are distributed in the Amazon and Atlantic forest regions. In this work, Eclipta dendensis sp. nov. from the Brazilian Atlantic Forest is described and illustrated. |
