The alien synanthropic Salticidae in Brazil (Araneae) / As aranhas Salticidae exóticas sinantrópicas no Brasil (Araneae)

Salticidae is the most diverse family of Araneae and in Brazil, there are 667 species. Among these species, five are synanthropic exotics: Plexippus paykulli (Audouin, 1826), Hasarius adansoni (Audouin, 1826), Menemerus bivittatus (Dufour, 1831), M. nigli Wesolowska & Freudenschuss, 2012 and Thyene coccineovittata (Simon, 1886). To understand the current distribution of these species in Brazil, seven collections of 643 lots were examined from seven Brazilian zoological collections. The synanthropic exotic species with the highest records were Plexippus paykulli, Menemerus bivittatus, and Hasarius adansoni, generally collected and associated with human dwellings and buildings. They are present in all regions (North, Northeast, Midwest, and South macro-regions), with the largest region, in all regions of the country in 22 states and 98 municipalities, followed by Hasarius adansoni in 17 states and 88 municipalities, Menemerus bivittatus in 19 states and 68 municipalities. Menemerus nigli and Thyene coccineovittata are from recent introductions that occurred in the city of Rio de Janeiro, Rio de Janeiro, Brazil.(AU)

New combination and redescription of Bumba humile, description of four new species and new records from Brazil (Araneae: Theraphosidae: Theraphosinae)

The taxonomic history of Bumba Pérez-Miles, Bonaldo & Miglio, 2014 is mainly based on the inclusion of the new species. Bumba have been characterized by the type IV urticating setae present, retrolateral process on male palpal tibia, palpal bulb resting in a ventral distal excavation of palpal tibia, metatarsus I passes between the two branches of tibial apophysis when flexed, presence of spiniform setae on prolateral and retrolateral sides of maxillae and coxae I-IV. In this paper we include the row of teeth (denticulate row) in the median region of the inferior prolateral keel in all male palps. This structure range from a residual tooth to a ridge of up to five teeth. Both, the denticulate row and the retrolateral process on male palpal tibia in males could be considered as putative synapomorphies for Bumba. Here, Homoeomma humile Vellard, 1924 is transferred to Bumba and redescribed, while the female is described for the first time. Bumba cabocla (Pérez-Miles, 2000) is synonymyzed with B. horrida (Schmidt, 1994). Bumba pulcherrimaklaasi (Schmidt, 1991) is transferred to Cyclosternum Ausserer, 1871. Four new species are described and illustrated: Bumba tapajos sp. nov. from state of Pará, Bumba cuiaba sp. nov. and Bumba rondonia sp. nov., both from states of Rondônia and Mato Grosso, respectively, and Bumba mineiros sp. nov. from Paraguay and the Brazilian states of Goiás, Mato Grosso and Mato Grosso do Sul. Diagnosis of B. horrida and B. lennoni are extended and figures of this species are presented.

Alien spiders: First record of Loxosceles gaucho Gertsch, 1967 (Araneae: Sicariidae) in the Amazon region, Brazil

We present the first record for Loxosceles gaucho Gertsch, 1967 in the Amazonian region of Brazil. Four males, fifteen females and forty-nine immatures were collected in different places in Manaus, Amazonas, Brazil. This is the third species of Loxosceles reported in the Amazon region along with L. amazonica Gertsch, 1967, and L. similis Moenkhaus, 1898. This is the first record of an invasive species of a venomous animal in the state of Amazonas, Brazil, which is noteworthy due to its synanthropic habit, which increases the risk to the local population.

On a new species of the genus Simlops (Araneae, Oonopidae) from Guyana, with notes on the bodanus group of species / Uma nova espécie do gênero Simlops da Guiana (Araneae, Oonopidae), e notas sobre o grupo de espécies bodanus

A new species of Simlops Bonaldo, Ott & Ruiz, 2014, S. kartabo sp. nov., from Guyana is described. The new species belongs to the putatively basal bodanus species group, sharing with other species of the group a relatively simple embolar distal third. The presence of a filiform accessory process on the conductor, previously evidenced only for S. guatopo Brescovit, 2014 is also identified here for S. bodanus (Chickering, 1968), S. guyanensis Santos, 2014 and S. kartabo sp. nov. and may support the monophyly of the bodanus group.(AU)

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

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 characteristic blue iridescent setae covering the carapace, chelicerae, legs, and palps. The new species is sympatric with P. sazimai . Both species inhabit a habitat locally known as 'campos rupestres'.

A new genus of Neotropical spiders of the family Sparassidae (Arachnida: Araneae)

Nungara gen. nov. is proposed to include the type species, Nungara niveomaculata (Mello-Leitão, 1941) comb. nov., transferred from Olios Walckenaer, 1837 and two new species, described from males and females: N. anama sp. nov., from the states of Sergipe, Alagoas and Espírito Santo, and N. gaturama sp. nov., from the states of Sergipe, Bahia and Espírito Santo, all in Brazil. The new genus is distinguished from all other Neotropical sparassid genera by the presence of a deep tegular groove on the male palpal bulb and a hood-like projection on the median septum of the female epigyne. In addition, Olios fuscovariatus Mello-Leitão, 1943, Stasina koluene Mello-Leitão, 1941 and Polybetes proximus Mello-Leitão, 1943 are transferred to Nungara gen. nov. and considered junior synonyms of N. niveomaculata . All species are described and illustrated and a distribution map is provided.
