Symphylus ramivitta Walker

Ostiole closer to metacoxal cavity than to lateral margin of metapleuron ( Fig. 21a ); ostiole round, oriented ventrolaterally, visible in lateral view; lateral and posterior margins of ostiolar plate elevated; peritreme directed laterally, parallel to surrounding pleuron ( Fig. 21b ), median furrow developed basally; peritremal surface with scale-like microsculptures ( Fig. 21c ). Evaporatorium well developed on meso- and metapleuron; on metapleuron, evaporatorium completely covering ostiolar plate and reaching between coxal cavities, outer margin of metapleural evaporatorium convex; on mesopleuron, well developed on mesepimeron; evaporatorium deeply punctate ( Fig. 21a, d ); mushroom bodies irregular, alveoli with several trabeculae. Metathoracic spiracle wide; processes of the filter system of regular diameter, processes spiny and connected to each other by lateral expansions ( Fig. 21e ).
