Pachycoris torridus (Scopoli)

Ostioleinthemiddleof metapleuron ( Fig. 17a ); ostiole guttiform, oriented ventrolaterally, visible in lateral view; lateral and posterior margins of ostiolar plate elevated; peritreme spout-shaped, directed laterally ( Fig. 17b ), median furrow obsolete; peritremal surface with disorganized, elevated ridges ( Fig. 17c ). Evaporatorium well developed on meso- and metapleuron; on metapleuron, evaporatorium completely covering ostiolar plate and reaching between coxal cavities, outer margin of metapleural evaporatorium convex; on mesopleuron, well developed on mesepimeron; evaporatorium punctate ( Fig. 17d ); mushroom bodies irregular, alveoli with several trabeculae. Metathoracicspiracle wide; metapleural margin of spiracle with several setae; processes of the filter system of regular diameter, processes spiny ( Fig. 17f ).
