The genus Austrolimnius Carter & Zeck has its greatest known diversity in Oceania, but its fauna in the Americas is poorlyknown. In this paper, two new species—Austrolimnius uncatus sp. nov. and A. bocainensis sp. nov.—are described and illus-trated based on adult specimens collected at Serra da Bocaina National Park, São José do Barreiro Municipality, São PauloState, and Nova Friburgo Municipality, Rio de Janeiro State, Brazil. Austrolimnius uncatus sp. nov. is characterized by the longsetae on the mesotarsus, the medial expansion of the hind tibiae, and the hook-like shape of the male genitalia. Austrolimniusbocainensis sp. nov. can be recognized by the absence of setae on the mid-tarsus, the cylindrical hind tibiae, and the slightlycurved genitalia with few setae. A pictorial key for the Brazilian species of the genus is given. New records of Brazilian species of the genus are reported.

Two new species of Anthurium endemic to Rio de Janeiro, southeastern Brazil, are described. Anthurium cronembergerae and A. sakuraguianum occur in humid areas in the Atlantic Forest. Descriptions and illustrations are provided, together with commentary on geographic distribution, ecology, flowering and fruiting phenology and conservation status. Comparisons are made with other similar Brazilian species of Anthurium section Urospadix, to which the two new species are assigned.

Two new species of Paratubana Young, 1977 are described and illustrated from Rio de Janeiro state, southeastern Brazil, based on specimens collected in alpine fields (above 1,800 m) of the Serra dos Órgãos mountain range. Paratubana auromarginata sp. nov. (Pico da Caledônia) can be recognized by the paraphyses with the apex bifurcate, forming an outer subquadrate projection and inner spiniform process, whereas in P. takiyae sp. nov. (Parque Nacional da Serra dos Órgãos) the paraphyses have a pair of strong spiniform processes directed dorsally and crossing each other. The two new species are apparently closely related to each other and both use Eryngium L. (Apiaceae) as host plants. A key to males of the ten known species of the genus is added, as well as two maps of their known distribution.

A New Species

A new species of the freshwater amphipod Hyalella Smith, 1874 is described for the plateau of the Itatiaia National Park, located between the states of Minas Gerais and Rio de Janeiro, southeastern Brazil. This is the first Brazilian species of Hyalella found at more than 2,200 meters of altitude. The specimens were found in a small stream, buried under rocks, in the higher area of the Park. The main morphological characteristics that differentiate the new species are the extreme reduction of the size of the uropod 3, absence of apical setae on telson, absence of comb-scales on gnatopods 1 and 2, absence of curved seta on inner ramus of uropod 1 and sternal gills tubular on pereonites 3 to 7. The new species presents similarities with some cave species of the genus, apparently being troglophile and that is the process of adaptation to the hypogean habitat. The importance of creating new protected areas for the conservation of Hyalella in Brazil is discussed.

Two new species of Dilobopterus Signoret, 1850 are described from the Atlantic Rainforest of Rio de Janeiro State, Southeastern Brazil, based on specimens collected in Angra dos Reis (D. nelsoni sp. nov.) and Itatiaia (D. sakakibara sp. nov.). Holotypes are deposited in Museu Nacional, Universidade Federal do Rio de Janeiro. These are the first species of the genus described after the publication in 1977 of the last comprehensive monograph on the New World Cicadellini. We also describe the previously unknown male of D. segmentalis (Signoret, 1853) based on specimens from the Atlantic Rainforest of Espírito Santo State, Southeastern Brazil (municipality of Santa Teresa). We propose a group of species within Dilobopterus (trinotatus group) based on features of the paraphyses of D. trinotatus (Signoret, 1853), D. segmentalis, and D. sakakibara sp. nov..

Eremanthus praetermissus and E. ovatifolius, two new species from Brazil, are here described and illustrated. Eremanthus praetermissus is endemic to Serra do Mar, in the northeastern part of São Paulo state and the southern part of Rio de Janeiro state; it is characterized by hemispherical, brown syncephalia, heads connate for 1/3 to 2/5 of their length, with 3–4 florets per head and brown phyllaries with purple apices. Eremanthus ovatifolius is endemic to campos rupestres of Pico da Aliança, in the eastern part of Minas Gerais state, and is characterized by ovate leaves, hemispherical syncephalia, heads connate for 1/4 to 1/2 of their length and 3–4 florets per head. The affinities of these species are discussed. A key to all species of Eremanthus is provided.

Shape And Size

Anaulacomera currently contains 147 valid species, of those 50 are recorded from Brazil. The genus is further divided into six subgenera, which can be distinguished on characteristics of the male terminalia. A new Brazilian species is presently proposed, Anaulacomera (Anallomes) curvata sp. nov., based on three males and one female collected at Parque Nacional de Itatiaia, Itatiaia, Rio de Janeiro State. It can be distinguished from all other species because of the pair of cerciform projections of the tenth male abdominal tergite and a combination of shape and size of the male cerci.

A new species of Multumbo Roewer, 1927 (Gonyleptidae: Hernandariinae), M. dimorphicus sp. nov., is described from Rio de Janeiro state, southeastern Brazil. It presents sexual dimorphism in leg IV, contrasting remarkably with the type species of the hitherto monotypic genus Multumbo and the closest genera (Piassagera Roewer, 1928 and Pseudotrogulus Roewer, 1932), which were all thought to have lost this dimorphism. The presence of sexual dimorphism in M. dimorphicus implies a complex scenario of loss or reversal of this character. New records are given of type species of genus, Multumbo terrenus Roewer, 1913, for which a lectotype is designated. New diagnoses are provided for Hernandariinae and Multumbo. Multumbo and Piassagera are transferred from the Gonyleptinae to the Hernandariinae.Uma nova espécie de Multumbo Roewer, 1927, M. dimorphicus sp. nov., é descrita do estado do Rio de Janeiro. Ela apresenta dimorfismo sexual na perna IV, condição em notável contraste com a espécie-tipo do até então gênero monotípico Multumbo e com os gêneros mais relacionados, Piassagera Roewer, 1928 e Pseudotrogulus Roewer, 1932, nos quais esse dimorfismo era considerado como perdido. A presença de dimorfismo sexual em M. dimorphicus sugere um complexo cenário de perda ou reversão desse dimorfismo. Também foram incluídos novos registros da espécie-tipo do gênero, Multumbo terrenus Roewer, 1913, e um lectótipo é designado. Novas diagnoses para Hernandariinae and Multumbo são apresentadas. Multumbo e Piassagera são aqui transferidos de Gonyleptinae para Hernandariinae.

The genus Alterosa Blahnik (2005), with 39 extant species, is endemic to Atlantic Forest areas of southern and southeastern Brazil. Herein, we describe and illustrate two new species from Rio de Janeiro state, southeastern Brazil: Alterosa cornuta sp. nov., easily diagnosed by the horn-like intermediate appendages crossing each other, and A. araras sp. nov., recognized mainly by the extremely developed basodorsal protuberance on tergum X and by the rod-like, mesally curved preanal appendages, with at least 2 stout spine-like setae positioned at mid length and with the apex cupped. Additionally, a new distributional record for Espírito Santo state, southeastern Brazil, is provided for Alterosa falcata Blahnik (2005).
