Abstract We present here a taxonomic study of Apocynaceae from the Atlantic Forest remnants in the state of Rio Grande do Norte (RN), Northeast Brazil. Twenty-four species in 18 genera, distributed in Apocynoid grade (3 genera/5 species), Asclepiadoideae (8 genera/10 spp.), and Rauvolfioid grade (7 genera/9 spp.) were recorded. The most species-rich genera were Aspidosperma, Ditassa, and Mandevilla with three species each. The other genera were represented by one species each. Five genera and seven species were recorded in Rio Grande do Norte for the first time. Descriptions, identification key and comments on distribution and taxonomy of both genera and species are presented, as well as illustrations and figures.

First Time

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.

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

Genus One

The Bromeliaceae Flora for the state of Rio Grande do Norte, Northeastern Brazil, is presented, based on extensive fieldwork, morphological analyses using herbarium and freshly collected material, and specialized literature. Twenty-six species of bromeliads were recorded in Rio Grande do Norte, distributed in ten genera and in three subfamilies. Bromelioideae was the richest subfamily (eight genera/14 species), followed by Tillandsioideae (one genus/12 species), and Pitcairnioideae (one genus/one species). Aechmea mertensii, Hohenbergia horrida and Tillandsia tenuifolia are new records for Rio Grande do Norte. Eight species (31%) are restricted to the Eastern portion of the state, in the Atlantic Forest. Caatinga dry woodlands harbor 18 species, with remarkable presence of Bromelia laciniosa, Encholirium spectabile, Tillandsia recurvata and T. streptocarpa, the four most widely distributed taxa. We discuss problems related to unclear taxonomic circumscriptions of species or diverging information between authors, more expressively in Hohenbergia, but also in Aechmea, Cryptanthus and Tillandsia. The data presented here might contribute to better understand the morphological variation of these taxa and suggest additional research on their taxonomy. Morphological descriptions, general comments, a map, photo plates and an identification key for all taxa are provided.

The orchid bee fauna of Estação Ecológica de Murici (ESEC Murici), in the state of Alagoas, one of the largest remnants of the Atlantic Rain Forest in northeastern Brazil, was surveyed for the first time. Seven hundred and twenty-one orchid-bee males belonging to 17 species were collected from the 3rd to the 10th of September, 2009. Besides the recently described Eulaema (Apeulaema) felipei Nemésio, 2010, three other species recorded at ESEC Murici deserve further attention: Euglossa amazonica Dressler, 1982b, recorded for the first time outside the Amazon Basin; Euglossa milenae Bembé, 2007 and Euglossa analis Westwood, 1840, both recorded for the first time in the Atlantic Forest of northeastern Brazil north to São Francisco river. These results together with previous samplings in the state of Alagoas reveal that at least 22 orchid-bee species are now known to occur there. Three other species not recorded for Alagoas yet are known from the neighbor states of Sergipe, Pernambuco, and Paraíba. An identification key to all 25 species of Euglossina known to occur in the states of Alagoas, Sergipe, Pernambuco, Paraíba, and Rio Grande do Norte is provided.

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.

Twenty six species of Scaphopoda, included in 12 genera and five families were identified. Within these, Fustiaria stenoschiza (Pilsbry & Sharp, 1897), Gadila pocula n.comb. (Dall, 1889); G. simpsoni n.comb. (Henderson, 1920) and G. pandionis (Verril & Smith in Verril, 1880) are recorded for the first time for Brazil and two new species of the genus Cadulus are here described. Besides that, six species previously recorded from north and northeast Brazil have their geographical range expanded southward: Antalis circumcincta (Watson, 1879), Episiphon didymum (Watson, 1879), Ep. sowerbyi (Guilding, 1834), Entalina platamodes (Watson, 1879), Gadila dominguensis (Orbigny, 1853) and Compressidens pressum (Pilsbry & Sharp, 1897). In the other hand, Paradentalium infractum n.comb. (Odhner, 1931) has its geographical distribution extended northward to the state of Maranhão (02ºS). Gadila acus (Dall, 1889) is proposed as junior synonym of G. dominguensis (Orbigny, 1853).

The orchid-bee fauna of ‘Reserva Biológica de Una’ (REBIO Una), one of the largest Atlantic Forest remnants in southern Bahia, eastern Brazil, was surveyed for the first time. Baits with sixteen different scents were used to attract males of orchid bees. Eight hundred and fifty-nine males belonging to 26 species were actively collected with insect nets during 60 hours in January and February, 2009, and January, 2010. Euglossa avicula Dressler, 1982 and Euglossa milenae Bembé, 2007 have been recorded for the first time in the state of Bahia. It was found that REBIO Una has one of the most diverse and rich orchid-bee faunas of the entire Atlantic Forest domain and holds some rare species, such as Euglossa cyanochloraMoure, 1996.

Abstract The knowledge of ant assemblages that occurs in Conservation Units in the Atlantic Forest domain is a priority, considering the number of endemic species and the impacts that this biome has been suffering. The aim of this study was to evaluate ant assemblages in the Turvo State Park, which is the largest conservation unit in the State of Rio Grande do Sul and presents an important role on biodiversity protection. Two samplings were conducted in 2019, one in the summer (January) and the other in the spring (November and December), at five sites 2 km apart, with pitfall traps (soil and canopy), sardine baits, glucose, beating net, sweeping net and manual collection. We sampled 121 species in the summer and 120 in the spring, totaling 163 ant species. A total of 78 species (47.8%) occurred in both sampling seasons. The richest genera in the study were Camponotus (S = 30), Pheidole (S = 23) and Linepithema (S = 11). Seventeen species were recorded for the first time for Rio Grande do Sul state. The results indicate that this is one of the most species-rich assemblages of ants ever surveyed in a conservation unit in southern Brazil. The study highlights the importance of Conservation Units as protected environments against habitat loss for ant biodiversity. The results of this study contribute to myrmecofauna knowledge and serve as a basis for environmental impact studies, management plans and conservation of Atlantic Forest remnants.

Thirty-two specimens of Columbina picui (picui ground-dove) were examined, and a collection of arthropods was made by washing the external surface of the body and the nasal cavity. The species in the order Phthiraptera found and their respective prevalences, mean abundance and mean intensity were: Columbicola passerinae (84.4%; 10.3; 12.2), Hohorstiella passerinae (21.9%; 0.7; 3.1) and Physconelloides eurysema (3.1%; 0.1; 2). The gamasid mites found in the birds and their respective prevalences, mean abundance and mean intensity were: Pellonyssus marui (31.3%; 1.2; 3.9), Ornithonyssus bursa (15.6%; 0.2. ;1.2) and Mesonyssus sp. (6.3%; 0.1; 1). Columbicola passerinae, H. passerinae, P. eurysema, O. bursa, P. marui and Mesonyssus sp. were recorded for the first time infecting C. picui in Brazil. Except for O. bursa, the other species are reported for the first time in the state of Rio Grande do Sul, Brazil.
