Sphyrocoris obliquus

Sphyrocoris obliquus (Germar) Ostiole closer to metacoxal cavity than to lateral margin of metapleuron (Fig. 19a); ostiole elliptic, oriented ventrolaterally, not visible in lateral view; peritreme grooveshaped, smoking-pipe-like, directed laterally and apically ample and curved anteriorly, parallel to surrounding pleuron (Fig. 19b), median furrow well developed; peritremal surface smooth with spike-like microsculptures and setae along the median furrow (Fig. 19c). Evaporatorium well developed on meso- and metapleuron; on metapleuron, evaporatorium completely covering ostiolar plate and tapered toward coxal cavities; reduced on mesopleuron; evaporatorium punctate and setose (Fig. 19d); mushroom bodies irregular, alveoli with few trabeculae. Metathoracic spiracle narrow; metapleural margin of spiracle with several setae; processes of the filter system of irregular diameter, some bifurcate apically, processes spiny (Fig. 19e).
