Abstract
This study focused on species of Heimbra Cameron, 1909 (Hymenoptera, Eurytomidae, Heimbrinae), a small genus of chalcid flies poorly represented in entomological collections, from two Brazilian savanna areas in Central Brazil. The surveys were carried out with Malaise, Moericke, light traps and sweep net and lasted from February 2018 to May 2019. Herein we provide new geographical records to H. opaca (Ashmead, 1894) and H. parallela Stage & Snelling, 1986.
Highlights
The delimitation of the species distribution area is essential for understanding biodiversity and conservation (Myers et al 2000; Lamoreux et al 2006)
The examined material was composed of specimens of Heimbra sampled between February 2018 and May 2019 in areas of Brazilian savanna at Parque Nacional da Chapada dos Veadeiros (PNCV), in Alto Paraíso de Goiás, State of Goiás and at Parque Nacional Grande Sertão Veredas (PNGSV), in Chapada Gaúcha, State of Minas Gerais, both in Central Brazil
Among the six known species of Heimbra, H. opaca is the species with the greatest number of known specimens (n = 55), corresponding to a proportion female / male = 1.3 approximately
