New data about slender orb-weaving species of the cosmopolitan genus Tetragnatha are presented. Tetragnatha chauliodus (Thorell, 1890) and Tetragnatha tenuissima O. Pickard-Cambridge, 1889 are redescribed, including one synonymy for each species and the first record of the first species to the Neotropical region. Also, three new species are herein described, all based on males and females. Tetragnatha megalocera new species is recorded exclusively from Brazil (Espírito Santo, Rio de Janeiro, Rio Grande do Sul and São Paulo states), while Tetragnatha renatoi new species is recorded from Venezuela, Argentina (Misiones) and Brazil (Paraná, Pernambuco, Rio Grande do Sul, Rondônia, Santa Catarina and São Paulo states). Finally, Tetragnatha chiyokoae new species is described from Yunnan province (China) and Okinawa (Japan), with an additional record for Taiwan. Furthermore, Tetragnatha exilima (Mello-Leitão, 1943), Tetragnatha filigastra Mello-Leitão, 1943 and Tetragnatha lactescens (Mello-Leitão, 1947) are nomina dubia.

Abstract: A new species of the genus Temnocephala Blanchard, 1849 from southern Brazil was found on two species of anomuran crustaceans, Aegla spinipalma Bond-Buckup & Buckup, 1994 and Aegla grisella Bond-Buckup & Buckup, 1994, the latter classified as a vulnerable species by the "Lista de Referência da Fauna Ameaçada de Extinção no Rio Grande do Sul. Decreto no 41.672, de 11 junho de 2002". The crustaceans were collected from a tributary creek of the Forqueta river, Perau de Janeiro, Arvorezinha and a tributary creek of the Fão river, Pouso Novo, Rio Grande do Sul, Brazil; both localities belong to the Sub-Basin of Forqueta River. The new species differs from seven other temnocephalans epibionts on Aegla Leach, 1820, by having the following characters: 1. a long and slightly curved cirrus, 2. two vaginal sphincters, one proximal, big and asymmetric, and one distal, smaller and symmetric, and; 3. longer than wide, elongated epidermal 'excretory' syncytial plates (EPs), with a almost horizontally central excretory pore, displaced to the anterior portion of the plate. The new species' EP is the largest in total length among epibionts temnocephalans in crustaceans already registered. Regarding the similarities with the male reproductive system of Temnocephala axenosMonticelli, 1898, the new species has important differences in the female reproductive system. It has a larger proximal vaginal sphincter, located in the middle of the vagina, while the smaller distal one is at the extreme end of the organ. Besides that, the vaginal portion between the proximal and distal sphincters is conspicuous, with a strong muscular wall. This is the first record of a species of Temnocephala in the Taquari Valley, as well in the 'Perau de Janeiro', which is an area with a rich endemic fauna.

The genus Magulla Simon 1892 is revalidated and redescribed. The female of the type species M. obesa Simon 1892 is redescribed and the male is described for the first time. Magulla janeirus (Keyserling 1891) is considered a valid species. Magulla symmetrica Bücherl 1949 is transferred to Plesiopelma Pocock 1901, and considered a junior synonym of P. insulare (Mello-Leitão 1923). Additionally, two new species are described from Brazil: M. buecherli n. sp. from Ilhabela, São Paulo and M. brescoviti n. sp. from São Francisco de Paula, Rio Grande do Sul.

Maruina is an aquatic genus of Psychodidae with larvae and pupae adapted for life in flowing water. The genus is restricted to the Western Hemisphere, with the majority of species distributed in the Neotropical region. 39 Maruina species are described, with 11 currently known to occur in Brazil, all recorded from the eastern Biomes of Atlantic forest and Caatinga. Here we describe four new Maruina species collected from Brazil: Maruina (Aculcina) roraimensis sp. nov., Maruina (Maruina) kallyntrona sp. nov. and M. (M.) mystax sp. nov. constitute the first report of Maruina from Amazonia and M. (A.) pila sp. nov. from the southern portion of the Atlantic forest expands the distribution of the genus to Rio Grande do Sul, the southernmost state of Brazil. Type specimens of some described species were also studied. Redescriptions are completed for M. (M.) garota and M. (M.) namorada, and additional characters and figures are presented for M. (A.) duckhousei, M. (M.) barrettoi and M. (M.) jezeki. M. pilosella and M. spinosa are considered nomina dubia. Diagnostic characters for the genus and both subgenera are revised and distribution maps for Maruina species recorded in Brazil are provided.

Here we provide the first record of Ceriomydas crassipes (Westwood, 1841) from the state of Rio Grande do Sul, Brazil. Previously, this species was recorded only in the southeastern Brazilian states of São Paulo, Rio de Janeiro, Minas Gerais and Espírito Santo. Therefore, this record extends the  range of C. crassipes further south to include the southernmost state of Brazil.

This paper presents the description of Ennearthron victori sp. nov. In contrast to all known species of this genus, E. victori is the first one occurring in the Southern Hemisphere (Neotropical Region, Brazil, Minas Gerais and São Paulo States) and, the only one in which males lack a fovea on the first ventrite.

The genus Helvetia Peckham & Peckham, 1894 is revised. The species H. zebrina Simon, 1901 and H. zonata Simon, 1901 are synonymized with H. cancrimana (Taczanowski, 1872). The species H. insularis (Banks, 1902) is synonymized with H. albovittata Simon, 1901. The genus Deloripa Simon, 1901 is considered a junior synonym of Helvetia by transfer of its type species, resulting in the new combination Helvetia semialba (Simon, 1901). The species Cotinusa humillima Mello-Leitão, 1943, transferred to Helvetia by Galiano, is revalidated. Helvetia roeweri (Soares & Camargo, 1948) comb. nov. is transferred from the genus Naubolus Simon, 1901. The epigynal structures of the type species H. santarema Peckham & Peckham, 1894 and those of H. semialba, H. albovittata, H. cancrimana and H. roeweri are illustrated, as well as the palp of H. humillima. Helvetia roeweri is redescribed and four new species are described: Helvetia labiata (Rio Grande do Sul, Brazil), Helvetia stridulans (Espírito Santo, Brazil), Helvetia rinaldiae (Pará and São Paulo, Brazil) and Helvetia galianoae (Misiones, Argentina). New records for H. cancrimana, H. albovittata and H. roeweri are given.

Mecistogaster is a New World genus of Pseudostigmatidae (Odonata) that is poorly studied due to its preference for flying in forest clearings and trails. In Brazil, only one endemic species, Mecistogaster amalia (Burmeister), is known. The distribution of M. amalia extends from Southest Brazil (Rio de Janeiro and São Paulo states) to Argentina. Herein, we report M. amalia for the first time in Rio Grande do Sul State, Southern Brazil. This record extends the species’ range ca. 630 km from the previous report at Paranaense Forest in Misiones province. Mecistogaster amalia (Burmeister) Odonata: Pseudostigmatidae: Primeiro Registro para o Estado do Rio Grande do Sul, Brasil Resumo. Mecistogaster é um gênero da Família Pseudostigmatidae, restrito ao Novo Mundo e pobremente estudado devido sua preferência por clareiras e trilhas dentro de matas. No Brasil, apenas uma espécie é conhecida, Mecistogaster amalia (Burmeister). A distribuição de M. amalia se estende do sudeste do Brasil (nos estados do Rio de Janeiro e São Paulo) até a Argentina. Aqui, reportamos pela primeira vez M. amalia para o estado do Rio Grande do Sul State, Sul do Brasil. O presente estudo amplia o registro de ocorrência da espécie em 630 km, a partir do registro anterior na Floresta Paranaense, na Província de Missiones, Argentina.
