Tetyra antillarum Kirkaldy

Ostioleinthemiddleof metapleuron ( Fig. 22a ); ostiole elliptic, oriented posterolaterally, visible in lateral view; lateral and posterior margins of ostiolar plate elevated; peritreme spout-shaped, directed laterally ( Fig. 22b ), median furrow obsolete; peritremal surface reticulate, with elevated ridges ( Fig. 22c ). Evaporatorium well developed on meso- and metapleuron; on metapleuron, evaporatorium completely covering ostiolar plate and reaching between coxal cavities, outer marginof metapleural evaporatorium convex; on mesopleuron, well developed on mesepimeron; evaporatorium with minute sensilla ( Fig. 22d ) and punctate ( Fig. 22e ); mushroom bodies irregular, alveoli with several trabeculae. Metathoracicspiracle wide; metapleural margin of spiracle with several setae; processes of the filter system of regular diameter, processes spiny ( Fig. 22f ).
