  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 survey of the spider genus Lipocrea Thorell, 1878 (Araneae, Araneidae) from Guiyang City, Southwest China: An integrated morphological and molecular approach

Abstract

A survey was undertaken to study the spider genus Lipocrea Thorell, 1878, from Guiyang City, Guizhou Province, southwest China. A total of two species is here addressed based on morphology and five methods of molecular species delimitation, comprising L. guiyang J. Zhang, Yu & Mi, sp. nov. and L. fusiformis (Thorell, 1877), the type species of the genus as well as a new record for mainland China. These two species are distributed in Huaxi District and Kaiyang County of Guiyang, respectively, providing the first formal record of this genus from mainland China.
