Amblypygi, Opiliones, Schizomida, Scorpiones and Chilopoda, Tocantins, Brazil

Abstract

The Tocantins 2007 Expedition of the Project “Aracnídeos e Miriápodes da Mata Atlântica” (AMMA) produced many new records of arachnids and centipedes, with 61 morphotypes identified. Among the results are: OPILIONES: 30 morphotypes with six new records of families and one of subfamily from Tocantins state; discovery of two undescribed species of Roquettea Mello-Leitão, 1931; Saramacia alvarengai Kury, 1997 is newly considered a junior subjective synonym of Saramacia annulata (Mello-Leitão, 1931); Brotasus Roewer, 1928 is transferred to Escadabiidae; the gonyleptid genera Parapachyloides Roewer, 1913 and Schubartesia B. Soares, 1944 are transferred to Gonyleptinae; SCHIZOMIDA: one species, new record of the order from Tocantins and from the Cerrado biome; SCORPIONES: seven species, one of them new record from Tocantins and two morphotypes; Chilopoda: 19 morphotypes, SCUTIGEROMORPHA: a widespread species Sphendononema guildingii (Newport, 1845) and another morphotype; GEOPHILOMORPHA: one morphotype; SCOLOPENDROMORPHA: 16 morphotypes, seven of them new records.

Arachnids from Araripe Plateau, Ceará, Brazil

“…Pseudopucrolia discrepans (Roewer, 1943) is usually found in forested enclaves in northeastern Brazil and in the Atlantic Forest in Paraíba and Parnambuco (Mendes 2011). Parapachyloides uncinatus (Soerensen, 1879) (Figure 3) is widely distributed throughout the Cerrado and Caatinga biomes (Kury et al 2010), mostly associated with more humid areas (pers. obs.).…”

First record of Stenochrus portoricensis Chamberlin, 1922 (Arachnida: Schizomida: Hubbardiidae) for the Pernambuco state, Brazil

“…In Brazil, this species has been sighted in São Paulo, Rio de Janeiro, Bahia, and Tocantins states (Tourinho and Kury, 1999;Santos et al, 2008;Kury et al, 2010). This species is characterized by the presence of two setae that are linearly arranged along the propeltidium (Figure 1a), a 'spur' pedipalp in a medial trochanter (Figure 1b), and internal female genitalia (Tourinho and Kury, 1999).…”

“…No tocante a sua ictiofauna cavernícola, os trabalhos são escassos. A área cárstica da Lagoa da Confusão (TO) é um bom exemplo de que, apesar de trabalhos de bioespeleologia já terem sido realizados na área por Kury et al (2010), há somente um estudo preliminar sobre sua ictiofauna subterrânea, realizado por Silva et al (2011), que relatou uma provável população troglófila da espécie Rhamdia sp. na caverna Gruta Casa de Pedra.…”
