Abstract A new species of Trichostrongyloidea (Nematoda: Heligmonellidae), Hassalstrongylus lauroi n. sp., is described from specimens collected from the small intestine of the rodent Hylaeamys seuanezi in the Atlantic Forest of northeastern Brazil (Igrapiúna, state of Bahia). The genus Hassalstrongylus includes 17 species, which parasitize rodents occurring in the Neotropical and Nearctic regions. It differs from the genus Stilestrongylus through its smaller number of ridges in the synlophe and through the size of the genital cone. The main taxonomic characteristics of this new species are the subsymmetrical caudal bursa of type 2-2-1, ray 8 branching out at the base of the dorsal trunk, right lobe smaller than the left, and rays 4 and 5 of robust nature. In addition, the ornamental ray 5 and the robustness of ray 4 on the male caudal bursa, along with the modification of the ridges of the posterior end of the female, allow us to consider the specimens found to be a new species.

AbstractA new species of Nippostrongylinae (Nematoda: Heligmonellidae), Stilestrongylus rolandoi n. sp., is described from specimens collected from the small intestine of the rodent Euryoryzomys russatus in the Atlantic Forest (Santo Amaro da Imperatriz, Santa Catarina state, southern Brazil). The genus Stilestrongylus includes 23 species, which parasitize rodents occurring in the Neotropical region. Stilestrongylus aureus (Durette-Desset & Sutton, 1985) from Argentina, S. azarai (Durette-Desset & Sutton, 1985) from Argentina, S. flavescens (Sutton & Durette-Desset, 1991) from Uruguay, S. franciscanus (Digiani & Durette-Desset, 2002) from Argentina, S. gracielae (Digiani & Durette-Desset, 2006) from Argentina, and S. oryzomysi (Sutton & Durette-Desset, 1991) from Argentina are closely related to Stilestrongylus rolandoi n. sp., all having caudal bursa patterns of types 1–4 in one of the lobes. Stilestrongylus rolandoi n. sp. is distinguished from the aforementioned species by its ray 6 being short in relation to rays 4 and 5, which are long and robust, and by having caudal bursa patterns of types 1–4 in both lobes. The new species has 27 ridges in the mid-body in males, and 24 in females, and has one of the highest ratios of spicule length to body length (21−33%) in this genus.

A new species, Coleodactylus elizae sp. nov., is described for the Atlantic Forest of Northeastern Brazil. It is distinguishedfrom other Coleodactylus species by the following character combinations: one nearly completely divided or two rostralscales, dorsal scales smooth and four scales forming the ungual sheath. The color pattern consists of white spots distributed over a pinkish background. Coleodactylus elizae sp. nov. is a forest species inhabiting bromeliads.

Two species of hubbardiid microwhipscorpions (Schizomida: Hubbardiidae) are recorded from the Brazilian Atlantic Forest. Rowlandius linsduarteae sp. nov. is described and illustrated based on specimens from Mata do Buraquinho forest reserve, João Pessoa, state of Paraíba, northeastern Brazil. This species is apparently related to Rowlandius sul Cokendolpher & Reddell 2000, the only species of the genus known from continental South America, and represents new evidence of a biogeographic relationship between Amazonia and the northeastern Brazilian Atlantic Forest. Stenochrus portoricensis Chamberlin, a widely distributed species, is newly recorded from the states of São Paulo and Bahia, respectively, in southeastern and northeastern Brazil. The latter record refers to several female specimens associated with abandoned arboreal termite nests in a cocoa plantation.

A new species of Aparasphenodon is described from patches of arboreal restinga within the Atlantic Forest Biome, in a region known as Baixo Sul in southern Bahia, northeastern Brazil. Aparasphenodon arapapa sp. nov. is promptly diagnosed from other Aparasphenodon mainly by having small size (male snout-vent length 57.4–58.1 mm), loreal region flattened and wide, and canthus rostralis rounded and poorly elevated. The wide and flattened snout resembles that found in Triprion and Diaglena, and possibly is a parallelism (homoplasy) related to the phragmotic behavior of casque-headed tree frogs to their microhabitat usage. The decision to allocate the new species in the genus Aparasphenodon is discussed in detail, as the single morphological synapomorphy of the genus, the presence of a prenasal bone, is insufficient to morphologically relate the new species to Aparasphenodon, Triprion, or Diaglena.

During analysis of herbarium collections for a taxonomic review of the Brazilian species of Gurania from the Atlantic forest, one new species was discovered. The new species is known only from the state of Bahia and honors Dr. Michael H. Nee. A description, illustrations, and photos of Gurania neei are presented along with comments on its similarities and differences with related species.

The Brazilian genus Machima Brunner von Wattenwyl, 1878 includes three valid species: M. paranensis Rehn, 1950 and M. scalprum Rehn, 1950 distributed on Southern and M. phyllacantha (Burmeister, 1838) from Northeastern Brazil. Herein we analyzed eleven male specimens of Machima from Parque Nacional de Itatiaia and propose a new species. Machima itatiaia sp. nov. is characterized by its main lobe of the cercus curving abruptly on apical two-thirds and accessory lobe as long as wide. The new species is the first record of the genus from Southeastern Brazil. Finally, we also present a key to species of Machima based on males.

A new species of Campylocentrum with reduced stems, small conduplicate leaves and long inflorescences is described from submontane Atlantic forest of Pernambuco state, northeastern Brazil. It is related to C. hirtellum, but differs by having a pedicellate ovary and base of the perianth both slightly papillate, smaller sepals, mid-lobe of the lip less than three times longer than the lateral lobes, lip 5-nerved, spur slightly longer than the pedicellate ovary and a glabrous capsule. It is illustrated and its affinities with allied species are also discussed.
