A new species of Masteria (Araneae: Dipluridae: Masteriinae) from southeastern Brazil Rev. Bras. Zool.
Pedroso,Denis Rafael; Baptista,Renner Luiz Cerqueira; Bertani,Rogério.
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 (Araneae: Paratropididae) from Venezuela Rev. Bras. Zool.
Bertani,Rogério.
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.

A new species of Pterinopelma (Araneae: Theraphosidae) from the highlands of the state of Minas Gerais, Brazil and description of the male of P. sazimai Rev. Bras. Zool.
Bertani,Rogério; Leal,Fernando.
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...

Avicularia rickwesti sp. nov., a remarkable new species of Avicularia (Theraphosidae: Aviculariinae) from Dominican Republic Rev. Bras. Zool.
Bertani,Rogério; Huff,Jeremy.
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.

Masteria manauara sp. nov., the first masteriine species from Brazil (Araneae: Dipluridae: Masteriinae) Rev. Bras. Zool.
Bertani,Rogério; Cruz,Wanessa Ribeiro; Oliveira,Maria Ermelinda do Espírito Santo.
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.

Metriura Drolshagen & Bäckstam, 2009 (Araneae: Dipluridae) is a junior synonym of Fufius Simon, 1888 (Araneae: Cyrtaucheniidae) Rev. Bras. Zool.
Bertani,Rogério; Fukushima,Caroline Sayuri; Nagahama,Roberto Hiroaki.
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...

Morphology, evolution and usage of urticating setae by tarantulas (Araneae: Theraphosidae) Rev. Bras. Zool.
Bertani,Rogério; Guadanucci,José Paulo Leite.
Urticating setae are exclusive to New World tarantulas and are found in approximately 90% of the New World species. Six morphological types have been proposed and, in several species, two morphological types can be found in the same individual. In the past few years, there has been growing concern to learn more about urticating setae, but many questions still remain unanswered. After studying individuals from several theraphosid species, we endeavored to find more about the segregation of the different types of setae into different abdominal regions, and the possible existence of patterns; the morphological variability of urticating setae types and their limits; whether there is variability in the length of urticating setae across the abdominal area; and...

Nhandu tripepii is a senior synonym of Nhandu vulpinus (Araneae: Theraphosidae) Rev. Bras. Zool.
Nagahama,Roberto H.; Fukushima,Caroline S.; Bertani,Rogério.
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.

Redescription of Avicularia taunayi and notes on its habitat and geographical distribution (Araneae: Theraphosidae: Aviculariinae) Rev. Bras. Zool.
Bertani,Rogério; Motta,Paulo Cesar.
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...

Vitalius nondescriptus comb. nov. (Araneae: Theraphosidae: Theraphosinae): an example of theraphosid taxonomic chaos Rev. Bras. Zool.
Bertani,Rogério; Nagahama,Roberto Hiroaki; Fukushima,Caroline Sayuri.
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...
