Acantholomidea porosa (Germar)

Ostiole closer to metacoxal cavity than to lateral margin of metapleuron ( Fig. 2a ); ostiole elliptical, oriented ventrally, not visible in lateral view; lateral and posterior margins of ostiolar plate leveled with remaining of metapleuron; peritreme small, directed posterolaterally, elevated from surrounding pleuron ( Fig. 2b ), median furrow obsolete; peritremal surface covered with rugose, scale-like microsculptures ( Fig. 2c ). Evaporatorium poorly developed on meso- and metapleuron; on metapleuron, evaporatorium surrounding ostiole and peritreme and along the metapleural margin of spiracle, but not reaching between coxal cavities, outer margin of metapleural evaporatorium sigmoid; on mesopleuron, developedonmesepimeronalongthespiracular margin and on lateral margin of mesopleuron; evaporatorium punctate ( Fig. 2d ); mushroom bodies irregular, alveoli with few trabeculae.Metathoracicspiracle narrow; processesof the filter system of irregular diameter, processes spiny and connected to each other by lateral expansions ( Fig. 2e ).
