New insect family for Australia: Chrysostylops australiensis Benda & Straka, gen. et sp. nov. (Strepsiptera: Stylopidae) described from Chrysocolletes aureus Leijs & Hogendoorn, 2021 (Hymenoptera: Colletidae)

Abstract

A new genus and species of Strepsiptera, Chrysostylops australiensis Benda & Straka, gen. et sp. nov., is described. It represents the first record of the family Stylopidae from Australia. It was parasitising the bee species Chrysocolletes aureus Leijs & Hogendoorn, 2021 (Neopasiphaeinae). The diagnosis and description of the genus and species are provided based on the characters of the female cephalothorax. Diagnostic characters are discussed. The male and first instar larvae of C. australiensis are unknown. We removed Hylecthrini Ulrich, 1930 reinst. stat. from synonymy based on the specific sculpture on the female cephalothorax. The tribe is specialised for bees of the family Colletidae.
