Chelycoris haglundi (Montandon)

Ostioleinthemiddleof metapleuron ( Fig. 6a ); ostiole round, oriented ventrally, not visible in lateral view; lateral and posterior margins of ostiolar plate elevated; peritremespoutshaped, directed posterolaterally, elevated and parallel to surrounding pleuron ( Fig. 6b ), median furrow well developed; peritremal surface covered with ridged, scale-like microsculptures ( Fig. 6c ). Evaporatoriumwelldevelopedon meso- and metapleuron; on metapleuron, evaporatorium covering most of ostiolar plate and reaching between coxal cavities, outer margin of metapleural evaporatorium straight and elevated; on mesopleuron, well developed on mesepimeron, reaching posterolateral angle of mesopleuron but not extending on mesopleural lateral margin; evaporatorium punctate ( Fig. 6d ); mushroom bodies irregular, alveoli with several trabeculae. Metathoracicspiracle wide; metapleural marginof spiraclewith setae; processesof thefiltersystemof conical, processes spiny ( Fig. 6e ).
