Galeacius martini Schouteden

Ostiole closer to metacoxal cavity than to lateral margin of metapleuron ( Fig. 12a ); ostiole round, oriented ventrolaterally, visible in lateral view; lateral and posterior margins of ostiolar plate elevated; peritreme groove-shaped, directed laterally and apically curved anteriorly, parallel to surrounding pleuron ( Fig. 12b ), median furrow well developed; peritremal surface with rugose, scale-like microsculptures ( Fig. 12c ). 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 punctate ( Fig. 12d ); mushroom bodies irregular, alveoli with few trabeculae. Metathoracic spiracle wide; metapleural marginof spiracle with several setae; processes of the filter system of irregular diameter, processes spiny ( Fig. 12e ).
