First record of Megaselia abdita (Schmitz, 1959) (Diptera: Phoridae) infestation in captive tarantulas (Araneae: Theraphosidae

  First record of Megaselia abdita (Schmitz, 1959) (Diptera: Phoridae) infestation in captive tarantulas (Araneae: Theraphosidae Abstract Flies of the genus Megaselia Rondani, 1856 exhibit exceptional ecological flexibility, with certain species acting as facultative parasites. This study presents the first documented cases of Megaselia abdita (Schmitz, 1959) infesting captive tarantulas (Araneae: Theraphosidae, Ceratogyrus darlingi Pocock, 1897 and Psalmopoeus irminia Saager, 1994) in terrarium settings. Our observations demonstrate that M . abdita colonise artificial habitats and exploit spider hosts similarly to Megaselia scalaris . Citation: Szymański, D.M., Szymański, D., Kłonowski, P. (2026).

A new species of Trechona C. L. Koch 1850 from Northeast Brazil (Araneae: Mygalomorphae: Dipluridae)

Abstract
Trechona garimpeira n. sp. is described here, based on specimens of both sexes, collected in the states of Bahia and Minas Gerais, located in the Northeast and Southeast regions of Brazil, respectively. The new species represents the first record of the genus from the Northeast region of Brazil and the “Tabuleiro” Forest ecosystem in the Atlantic Forest.
