| A new species of Masteria L. Koch, 1873 from iron ore caves at Caeté and Santa Bárbara, state of Minas Gerais, Brazil, Masteria emboaba sp. nov., is described. It was collected inside caves and in the litter of nearby dry forests. It is the first masteriine species described from southeastern Brazil and the second masteriine species for the country. The new species is the only known Masteria with only two eyes. Additionally, the male of M. emboaba sp. nov. has only two regular, thin spines at the apex of tibia I, lacking the tibial apophysis found in most other Masteria species. The only other described Masteria species that has spines in the place of tibial apophysis is M. aimeae (Alayón, 1995) from Cuba; however, the last species has a longer and sinuous... |

| A new species of Melloina Brignoli, 1985, Melloina santuario sp. nov., is described from a cave in Venezuela. This is the third species described in this rarely sampled genus, and the first species known from both male and female. The male of M. santuario sp. nov. is distinguished by a longer embolus and fewer number of spines on the anterior tarsi. Females and immatures are distinguished by having fewer numbers of labial cuspules. The description of a new species from male and female samples increases our knowledge about Melloina. This added knowledge is important to the understanding of mygalomorph relationships, mainly in the Theraphosoidina, as Melloina is a basal genus within the Paratropididae. |

| ABSTRACT We describe a new species of tarantula from the highlands of the state of Minas Gerais, Brazil. Males of the new species can be distinguished from congeners by having palpal bulb keels weakly developed, and metatarsus I strongly curved, touching apex of retrolateral spur when folded. Females can be distinguished by the color pattern, carapace and legs black with conspicuous white rings on distal femora, patellae, tibiae, and metatarsi. The male of Pterinopelma felipeleitei sp. nov. was previously misidentified and described under the name Pterinopelma sazimai Bertani, Nagahama & Fukushima, 2011. The true male of P. sazimai is herein described from a specimen collected near the type locality. Similar to the conspecific female, this male has... |

| A remarkable new species of Avicularia Lamarck, 1818, Avicularia rickwesti sp. nov., is described from Dominican Republic. Female specimens of the new species are unusual by having two very short and broad spermathecae with distal half strongly sclerotized, a feature not found in any other aviculariine. Additionally, it has the leg coxae with spiniform setae, smaller on leg I and prolateral leg II, larger, black on retrolateral leg II, prolateral and retrolateral leg III and prolateral leg IV. Males are unknown. The new species is known only from two localities, in southwestern Dominican Republic. This is the first record for the subfamily on Hispañola which is close to the northern boundary for the Aviculariinae distribution. |

| A new species of Masteria L. Koch, 1873 from Manaus, Brazil, Masteria manauara sp. nov., is herein described. The specimens were collected by hand or using litter bags in the leaf litter around Attalea attaleoides (Barb. Rodr.) palm trees. The new species resembles Masteria colombiensis Raven, 1981 by lacking paraembolic apophysis on male copulatory organs and having spiniform apophysis on the ventral metatarsus I. It differs in the tibial spur, made of two subdistal, spiniform and converging spurs. Females are unique in having two spermathecae with slender helicoidal stalks. Males and females have only six eyes, and are tiny, even when compared with other Masteria species. |

| The monotypic diplurid Metriura Drolshagen & Bäckstam, 2009 is placed in synonymy with Fufius (Cyrtaucheniidae) syn. nov. since Metriura lacks two of three diplurid synapomorphies (elongate posterior lateral spinnerets and the widely separated posterior median spinnerets) and shares synapomorphies with both aporoptychine cyrtaucheniids (subquadrate maxilla and a longer than wider labium) and Fufius (recurved and broad fovea, the typical incrassate tibia I of the male, with the spur having a single short branch and an apical megaspine, the basally curved metatarsus I and provided with a ventral tubercle). The type species of Metriura, M. striatipes Drolshagen & Bäckstam, 2009 is considered valid, and due to the synonymy of Metriura with... |

| The holotype of Eurypelma tripepii Dresco, 1984 from state of Pará, Brazil, is revised and illustrated. Its palpal bulb and tibial apophysis are similar in shape to species of Nhandu Lucas, 1983. Therefore, the species is transferred to the genus Nhandu, establishing the new combination Nhandu tripepii (Dresco, 1984) comb. nov., which is considered a senior synonym of Nhandu vulpinus (Schmidt, 1998) syn. nov. The protuberances present on the holotype's chelicerae are here considered a morphological anomaly. |

| We redescribe the poorly known tarantula species Avicularia taunayi (Mello-Leitão, 1920) and present information on its geographical distribution and habits. The spermatheca of the female is unusual for the genus: short, broad, with a median slight curvature and lobes on its basal, median and distal portions. The male resembles other Avicularia species but can be distinguished by the presence of a tibial apophysis on leg I in conjunction with legs I and IV having roughly the same length and the presence of pale rings on the distal femora, tibiae and metatarsi. Additionally, males and females have three pairs of light brown spots extending from the dorsum to the lateral region of the abdomen. Avicularia taunayi is found in the Brazilian Cerrado, a... |

| The male holotype of Hapalopus nondescriptus Mello-Leitão, 1926 is redescribed, illustrated and compared with freshly collected specimens from the type locality. The only difference noted among the holotype and the new material concerns the development of the subapical keel. Its taxonomic position is reinterpreted and discussed, resulting in its transfer to the genus Vitalius Lucas, Silva Junior & Bertani, 1993, and thus making the new combination Vitalius nondescriptus (Mello-Leitão, 1926) comb. nov. The female is described for the first time and the morphological variations in two males, born from the female used in the description, is presented and illustrated. The male differs from those of other Vitalius species by the palpal bulb with short... |
