Cydninae (Hemiptera, Heteroptera, Cydnidae) in Brazil: updated checklist, new records, and description of Tominotus ondulatus sp. nov.

Abstract

Cydninae is the largest subfamily among burrower bugs all around the world and for Brazil the genera Cyrtomenus, Dallasiellus, Ectinopus, Melanaethus, Onalips, Pangaeus, Prolobodes and Tominotus were reported with a total of 39 species, so far. Basing on the material of nine entomological collections, we updated the list to 47 species including new records and a new species, Tominotus ondulatus sp. nov. described from Restinga, Rio Grande do Sul. Distribution maps and photos of dorsal habits for several species are also provided.

Population dynamics, vertical distribution and damage characterization of burrower bug in peanut

“…During counting, bugs were categorized into adults and nymphs above 2.5 mm in length, followed by the estimated totaling of nymphs and adults for each square meter of the plots. The identification of species was based on a comparison of morphological characteristics with previously identified specimens based on data in the literature (Avendaño et al, 2017;2018). A representative sample of the collected specimens was dry assembled and deposited in the Hemiptera Collection of the Museum of Zoology of the University of São Paulo (MZ−USP).…”
