Ascanius hirtipes (Herrich-Schäffer)

Ostiole in the middle of on metapleuron ( Fig. 4a ); ostiole elliptical, oriented ventrolaterally, not visible in lateral view; posterior margin of ostiolar plate elevated; peritreme spout-shaped, directed posterolaterally, elevated and parallel to surrounding pleuron ( Fig. 4b ), median furrow well developed; peritremal surface covered with scale-like microsculptures ( Fig. 4c ). Evaporatorium well developed on meso- and metapleuron; on metapleuron, evaporatorium covering most of the ostiolar plate and reaching between coxal cavities, outer marginof metapleural evaporatorium concave; on mesopleuron, well developed on mesepimeron; evaporatorium punctate ( Fig. 4d ); mushroom bodies irregular, alveoli with several trabeculae. Metathoracic spiracle wide; processes of the filter system of regular diameter, processes spiny ( Fig. 4e ).
