I am in agreement with Dmitry. This insect is in the family Coreidae and probably Sphictyrtus chryseis but the species identification cannot be certain from the photographs. The photographs are superb quality but do not illustrate all important diagnostic characters. We have to be careful in the Neotropics as there are substantial numbers of undescribed species even in well known groups. It is best to capture a nice mating pair and send it off for identification. There are some great experts in Brazil for the Heteroptera.
I agree with Pietro and Marisol, and i found this bug in another diferent plant that i dont remember the name. However, as Clifford and Dmitry said, for sure, its nice you send this insect to brasilian expert.
Mira con ese chinche lo puedes encontrar en la versión degital de BIOLOGIA CENTRALI-AMERICANA, seccion Hemiptera, allí aparecen los tomo y láminas respectivas, digita en google este libro.- Juliàn
Your photos are among the best I have ever seen. Maybe you can find some way to make them both enhance your career and to preserve them for future generations.
Gracias, voy a revisar, pero acuerdate que es un trabajo muy desactualizado. El nombre Sphictyrtus chryseis concuerda mucho con el ejemplar de la foto.
