Misippus spinolae (Signoret)

Ostiole closer to metacoxal cavity than to lateral margin of metapleuron ( Fig. 15a ); ostiole round, oriented laterally, visible in lateral view; lateral and posterior margins of ostiolar plate leveled with remaining of metapleuron; peritreme obsolete ( Fig. 15b ), median furrow obsolete. Evaporatorium poorly developed on meso- and metapleuron; on metapleuron, evaporatorium surrounding ostiole, along the metapleural margin of spiracle, and reaching between coxal cavities; on mesopleuron, developed on mesepimeron along the spiracular margin and not reaching lateral margin of mesopleuron; evaporatorium punctate ( Fig. 15c ); mushroom bodies irregular, alveoli with few trabeculae. Metathoracic spiracle wide; processes of the filter system of regular diameter, processes smooth and connected to each other by lateral expansions ( Fig. 15e ).
