Antennal sensilla of two species of Gymnetis MacLeay, 1819 (Coleoptera: Scarabaeidae: Cetoniinae)

Abstract

Gymnetis pantherina meleagris (Burmeister, 1842)), Gymnetis rufilateris (Illiger, 1800), Gymnetis vandepolli Bates, 1889 (named as Gymnetis bajula vandepolli Olivier, 1789) from Mato Grosso do Sul State. From Minas Gerais State, Gonçalves and Louzada (2005) registered Gymnetis cupriventris Janson, 1880 and Gymnetis pantherina, while Puker et al. (2014) noted G. pantherina and G. undata (Olivier, 1789). The occurrence of G. undata and G. vandepolli in Brazil is doubtful since the Gymnetis review (Ratcliffe, 2018) registered the former to Caribbean and Guyana regions, and the last to Colombia and Central America. Evangelista Neto et al. (2018) collected G. hebraica, G. rufilateris, G. pantherina (named as G. rubrocincta (Schürhoff, 1937)), G. flavomarginata Blanchard, 1837 in Brasília, but the last species registered must be checked because G. flavomarginata possibly does not occurs in Brazil (Ratcliffe, 2018).Adult scarabs usually detect other scarabs, food sources, or nesting places by the detection of pheromones (
