Camirus moestus (Stål)

Ostiole closer to metacoxal cavity than to lateral margin of metapleuron ( Fig. 5a ); ostiole guttiform, oriented ventrally, not visible in lateral view; lateral and posterior margins of ostiolar plate leveled with remaining of metapleuron; peritreme small, elevated from surrounding pleuron, directed posterolaterally ( Fig. 5b ), median furrow obsolete; peritremal surface covered with conical, scale-like microsculptures ( Fig. 5c ). Evaporatorium poorly developed on meso- and metapleuron; on metapleuron, evaporatorium surrounding ostiole and peritremeand along the metapleural margin of spiracle, and reaching between coxal cavities, outermarginof metapleural evaporatorium sigmoid; on mesopleuron, developed on mesepimeron along the spiracular margin and on lateral margin of mesopleuron; evaporatorium punctate ( Fig. 5d ), punctures bearing long seta; mushroom bodies irregular, alveoli with few trabeculae. Metathoracic spiracle wide; processes of the filter system of regular diameter, processes spiny and connected to each other by few lateral expansions ( Fig. 5e ).
