Thomas USDA-ARSSubtropical AgriCUlture Research Laboratory 2301 S International Boulevard Weslaco, I exas 78596 Abstract The subfamily Asopinae ofthe stinkbug family Pentatomidae is revised for the Old World with a key to the genera and a review ofthe species with nomenclatural changes. The genus Tahitoc01is is removed from the Asopinae and placedtentativelywith the Podopinae. The genus Breddiniellais reducedto a synonym ofCazira. The genus Indtatus is reduced to a synonym oU,,{artinina. The genus Platynopus is divided into three genera by the restriction of Platynopus to include only five Indo- Pacific species; the elevation of the subgenus A/entre ~ieFiellustethe leveleffullgenus, andthe el'eetieneranewgenus Platynepiellusfol' the Afl'iean speeies formerly placedin Platynopus. AnewgenusAustralojallaiserectedfor Jalla versicolor. ThegeneraCantheconidea and &oontheeona aPe defined and their Pespecti'le species aligned in oonoordance with theil' definitiens. Fourteen species are thus transferred from Cantheconidea to Eocanthecona creating the following new combinations' Eooonth€Conajapanicola, Kooonthewna binotata, Eooonthecona latipes, &canthecona mitis, Eocanthecona neotibialis, Eocanthecona ornatula, Eocanthecona parva, Eocanthecona plebeja, Eocanthecona robusta, Eacanthecona ru!escens, Eacanthecona shikoklumsis, Eacanthecona thomsoni, Eacanthewna tibialis, and Eocanthecona vollenhoveni.
