  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 the trapdoor spider genus Tigidia Simon, 1892 (Araneae: Barychelidae) from the Deccan Plateau, India

Abstract

A new species of trapdoor spider, Tigidia singhal sp. nov., is described from the semi-arid grasslands of the Deccan Plateau in Maharashtra, India. Detailed morphological descriptions, measurements, and illustrations of the holotype female are provided. This discovery marks the first record of the genus Tigidia from a semi-arid, open natural ecosystem, significantly expanding its known biogeographic range beyond the evergreen and deciduous forest habitats of peninsular India. Additionally, we document natural history observations, including burrow architecture and microhabitat preferences. This find highlights the underexplored diversity of Indian mygalomorph spiders and underscores the critical need for biodiversity surveys in open natural ecosystems.
