Abstract

Flies of the family Tachinidae are parasitoids of a wide range of arthropods, and some tachinid lineages specialised and coevolved with distinct hosts. A few of these tachinids use social Hymenoptera as hosts. However, they are usually attacked by their hosts and present different strategies to avoid their aggressiveness. Here, we describe the first parasitoid fly that enters a wasp nest without being attacked, Brevialata deceptrix Dios & Gudin, gen. et sp. nov., reared from nests of Agelaia vicina (de Saussure, 1854) in Cajuru, São Paulo, Brazil. Additionally, it is the first tachinid fly with reduced wings, presenting a peculiar morphology, with reduced chaetotaxy, stout legs, and tarsi with digitiform extensions. Males of B. deceptrix Dios & Gudin, gen. et sp. nov. are fully described and illustrated, including detailed images of tarsal structures. We present a discussion on B. deceptrix Dios & Gudin, gen. et sp. nov. remarkable morphology, systematic positioning and curious life habits.

期刊介绍： Austral Entomology is a scientific journal of entomology for the Southern Hemisphere. It publishes Original Articles that are peer-reviewed research papers from the study of the behaviour, biology, biosystematics, conservation biology, ecology, evolution, forensic and medical entomology, molecular biology, public health, urban entomology, physiology and the use and control of insects, arachnids and myriapods. The journal also publishes Reviews on research and theory or commentaries on current areas of research, innovation or rapid development likely to be of broad interest – these may be submitted or invited. Book Reviews will also be considered provided the works are of global significance. Manuscripts from authors in the Northern Hemisphere are encouraged provided that the research has relevance to or broad readership within the Southern Hemisphere. All submissions are peer-reviewed by at least two referees expert in the field of the submitted paper. Special issues are encouraged; please contact the Chief Editor for further information.
