Soil mesofauna in differents systems of land use soil in upper River Solimões, ...
Morais, José Wellington; Oliveira, Viviane dos S.; Sales Dambros, Cristian de; Tapia-Coral, Sandra C.; Acioli, Agno Nonato SerrãoThe mesofauna has an important function in the soil and it is represented mainly by Acari Oribatida and Collembola. We report the first data on the density and diversity of the soil mesofauna in Benjamin Constant, Amazonas State, Brazil. The following systems were evaluated: primary forest, secondary forest, agroforestry system, cultivated areas and pastures. A total of 101 samples were collected 100 m apart fr...

Almeida, Marlus Queiroz; Salvatierra, Lidianne; Morais, José WellingtonWe present the first record for Theraphosa apophysis (Tinter, 1991) for Brazil. A male of T. apophysis was collected in São Gabriel da Cachoeira, Amazonas state, Brazil. This is the third species of Theraphosa in Brazil along with T. blondi (Latreille, 1804) and T. stirmi Rudloff & Weinmann, 2010. © 2018, Pensoft Publishers. All rights reserved.
A New Epigeous Species of Troglobius (Collembola: Paronellidae: Cyphoderinae) f...
Cipola, Nikolas Gioia; Morais, José Wellington; Bellini, Bruno CavalcanteTroglobius albertonoi sp. nov. (Collembola: Paronellidae: Cyphoderinae) from the Brazilian Amazon is described and illustrated. The shape of the mucro and unguis resemble those of T. ferroicus Zeppelini, Silva & Palacios-Vargas, recently described from Brazil, but the chaetotaxy is distinct. This is the 4th species of the genus and the 3rd from Brazil. Variation within the genus Troglobius of the dorsal chaetot...
First report of two species of scarab beetles (Coleoptera, Scarabaeidae) inside...
Alves-Oliveira, João Rafael; Mendes, Diego Matheus de Mello; Campos, Douglas de; Silva Neto, Alberto Moreira da; Morais, José WellingtonWe report for the first time the occurrence of two species of scarab beetles, Phileurus carinatus declivis Prell, 1914 (Scarabaeidae: Dynastinae) and Cyclidius elongatus (Olivier, 1789) (Cetoniinae: Cremastocheilini) inside nests of Azteca cf. chartifex Forel, 1896, a neotropical arboreal ant species. This report indicates that these two beetle species are associated, at least as inquilines, to this ant species...

Almeida, Marlus Queiroz; Alves-Oliveira, João Rafael; Mendes, Diego Matheus de Mello; Sobral, Rafael; Silva Neto, Alberto Moreira daWe 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 veno...
Abundance and phenology of Pseudoscorpiones (Arachnida) from a mixedwater inund...
Morais, José Wellington; Adis, Joachim U.; Mahnert, Volker; Berti-Filho, EvôneoA total of 675 Pseudoscorpiones, representing nine species, were captured during 12 months in an inundation forest near Manaus, which is covered by several meters of mixedwater for 5-7 months each year. In the terrestrial phase, the average abundance of pseudoscorpions in the soil (0-14 depth) was three times higher during the rainy season (140 ind./m2/month) when compared to the season with less rainfall (48 i...

The new species is mainly characterized by bluish-gray coloration and dorsal chaetotaxy presenting macrochaeta S7 on head, three macrochaetae (a6, m6 and p6) on margin of metathorax and 4+4 macrochaetae (a1, m2, m3 and m4i) on abdomen I. Characteristics of maxillary and lab...
