Terrestrial Isopods were sampled in four protected Atlantic Forest areas located in Serra do Mar, state of São Paulo, southeastern Brazil. A total of 2,217 individuals of six species (Atlantoscia sp., Benthana werneri, Pseudodiploexochus tabularis, Pudeoniscus obscurus, Styloniscus spinosus and Trichorhina sp.) were captured in pitfall traps. The exotic species S. spinosus is recorded for the first time for the Americas. Another introduced species, P. tabularis, previously recorded only from the state of Rio Grande do Sul, had its geographic distribution extended to the state of São Paulo. The most abundant isopods in this study belong to an undescribed species of Atlantoscia.

The Praxelinae comprises two genera—Praxelis and Chromolaena—and 19 species in Rio Grande do Sul, the southernmost State of Brazil. This is the first taxonomic treatment of these genera in the state according to their current circumscriptions. Chromolaena squarrosoramosa is formally reported for the first time for the flora of the state. The names C. callilepis and C. paraguariensis are used for the first time to refer to species previously known as Eupatorium polyanthum and E. angusticeps. Eupatorium angusticeps, considered in previous studies endemic to Rio Grande do Sul and probably extinct, is synonymized under C. paraguariensis and has its geographical range extended. Two neglected names, C. elliptica and C. latisquamulosa, are re-established, and C. umbelliformis is synonymized under C. elliptica. Furthermore, C. rhinanthacea is recollected for the first time after 40 years, and C. gentianoides is rediscovered in the state after almost 200 years of the original collection. Identification key and morphological descriptions, as well as distribution maps, field photographs, illustrations and general comments on the biology, ecology and identification of the species are provided.

Neognathophausia ingens (Dohrn, 1870) is a bathypelagic crustacean distributed worldwide. In the western Atlantic it has been recorded off the La Plata region, Argentina, and off the coast of Brazil, from the state of Bahia to Rio de Janeiro. We provide new records of N. ingens from the state of Rio Grande do Sul, Brazil, about 1188 km south of its previous distribution limit off Brazil, filling the gap between the central West Atlantic and Argentina. Five specimens were analyzed and drawings for all body regions and appendages are presented. Mandible, thoracopods 2, 4, 5, 6 and 8 and pleopods are illustrated and described for the first time. An updated synonym list and a distribution map for this species in Brazil are provided.

During a series of zooplankton surveys carried out during 1984, off the south coast of the state of Rio Grande do Norte, Brazil, several species of monstrilloids were present in the samples. A total of 50 individuals of monstrilloid copepods were collected. These belong to four species (Monstrilla brasiliensis Suárez-Morales & Dias, Cymbasoma cf. longispinosum, Cymbasoma cf. rigidum, and Cymbasoma gracilis Gurney). The taxonomic complexes formed by the species C. cf. longispinosum and C. cf. rigidum in Brazilian waters are discussed. The lengths of the specimens are provided in order to contribute to studies and revisions of the specimens belonging to these species-complexes. The species Monstrilla brasiliensis is recorded for the first time in the Rio Grande do Norte coastal region, thus expanding its geographical range in the Brazilian northeastern coast. The results presented herein increase to four the number of species of Monstrilloida known from off Rio Grande do Norte state.

The tick collection of the Museu de Historia Natural Capão da Imbuia was first sorted in the end of the 80's, and a list of specimens was published in 1992. During the last ten years, the collection has grown substantially and became the depository collection for type-specimens. The collection is the most regional representative depository of ticks from the State of Paraná, and it is one of the four largest Brazilian collections in number of specimens. All material was revised, and the data were computerized and catalogued in cards. To date, the collection includes 504 vials, with 2,073 specimens, belonging to 25 species and six genera of the families Argasidae and Ixodidae. The ticks were collected in regional and state parks and in green areas from 60 municipalities distributed within eight Brazilian states. This catalogue corrects some of the records published in 1992 for the state of Paraná and records new host species for Amblyomma aureolatum (Pallas, 1772), A. cajennense (Fabricius, 1787), A. longirostre (Koch, 1844), A. tigrinum Koch, 1844, Ixodes aragaoi Fonseca, 1935, I. auritulus Neumann, 1904, I. fuscipes Koch, 1844 and I. paranaensis Barros-Battesti, Arzua, Pichorim & Keirans, 2003. Amblyomma brasiliense Aragão, 1908, A. coelebs Neumann, 1899, A. nodosum Neumann, 1899 and I. fuscipes are recorded, for the first time, from the state of Paraná; A. longirostre from Rio Grande do Sul; I. fuscipes from Santa Catarina; I. schulzei Aragão & Fonseca, 1951 from Rondônia; and A. rotundatum Koch, 1844 from Bahia. In addition Haemaphysalis juxtakochi Cooley, 1946 and I. fuscipes are recorded for the first time, infesting birds.

Rio Grande do Sul (RS) is the southernmost state in Brazil and includes areas within the Pampa and Atlantic Forest biomes. The semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from RS are poorly known, with only 14 previously recorded species. We carried out two expeditions in this state, in 2002 and 2019, across 19 municipalities. Here, we provide new records for 19 species, of which 13 are recorded for the first time from the state, five have their distributions expanded, and one is recorded again from a same locality previously reported in the literature. Furthermore, 13 species were collected for the first time in the Pampa biome and one in the Atlantic Forest.

The Brazilian scorpion Tityus serrulatus is recorded for the first time in the central region of Rio Grande do Sul, thus filling a gap of 567 km in its distribution. A specimen of the scorpion was collected in the urban area of the municipality of Santa Maria (29°43′51.31″ S, 053°48′5.74″ W) on 31 June 2014. A map was generated with the points of occurrence of the species in the state.

Pilumnus dasypodus is reported for the first time in the state of Rio Grande do Norte, Northeastern Brazil. Sampling occurred in the north and south coast of the state in four locations (the farthest about 500 km of the known south distribution of the species). This new record increases the information about the distribution of this species, showing a possible relationship between the distribution of species and the Atlantic Tropical Ecoregion.

Temnocephala lutzi Monticelli, 1913, ectosymbiont on brachyuran freshwater crabs of the genus Trichodactylus Latreille, 1828 is recorded for the first time in the State of Rio Grande do Sul, southern Brazil. Two hundred and seventy-nine crabs of two species were examined: 211 Trichodactylus panoplus (von Martens, 1869) and 68 Trichodactylus fluviatilis Latreille, 1828 of which 51 (24.17%) and 28 (41.17%) were positive for T. lutzi, respectively. Crabs of both species carried eggs fixed, exclusively, on the floor of the branchial chambers and/or on the lower side of the gills. Adult as well as young specimens were found inside and outside the branchial chambers. The temnocephalans were always devoid of body pigmentation, although they kept the red eye pigment undiluted in specimens fixed by formalin. The cirrus of T. lutzi showed the typical shape for the species, while the dorsolateral, post tentacular 'excretory' syncytial plates, demonstrated by two special techniques (silver nitrate staining and SEM), appeared with an elliptical shape and a central nephridiopore.
