Chapter 20 ScentlessPlant Bugs (Rhopalidae) TrevorM. Fowles, Maria dei C. Coscarón, Antônio R. Paoizzi, IDd Scott P. Carroll Abstract Rhopalidae are closely related to the much more speciose Coreidae, andlike them are plant feeders, although more associated with reproductive tissuesand seeds. The two rhopalid subfamilies, Rhopalinae and Serinethinae, occuworldwider , with the latter more restricted to tropical latitudes. About 38 % oftheca. 210 rhopalid species and 38 % of the 21 genera have at least partially Neotropicaldistributions. The serinethine genus Jadera Stâl is particularly associatedwith the Neotropics and like other members of the subfamily feeds on seedsof Sapindaceae (soapberry farnily). Most Neotropical rhopalid species are unstudiedand, few appear to have major economic importance. However, serinet- hinesare important models in insect reproductive life history, behavior, and human-induced evolution. Rhopalids are not scentless, and a more accurate familyname is needed. 20.1 Introduction The rhopalids are a small worldwide farnily of approximately 200 species of plant- feedingbugs in 21 genera and 209 species (Henry 2009). Formerly treated as a subfamilofy the Coreidae, usually with the name Corizinae, Schaefer (1965) ended acenturyof taxonomic controversy with his definitive elevation of these insects to familyRhopalidae, with subfarnilies Rhopalinae and Serinethinae.
