Zvierckia storozhenkoi

( Figs. 33–34 )

This species has 14-segmented antennae, the widest antennomere being the 9 th, 1.45 mm long, 0.70 mm wide at the widest part, and with a surface on each side of about 0.73 mm 2. The 9 th antennomere is circular in the cross-section in the base, and elongated, ovoid, or almost rectangular in the cross-section in the tip. The whole surface of the antennomere is covered in protuberances and cuticular plates (12 µm x 10 µm) ( Fig. 33 , Fig. 34 ). A 6-porous coeloconic field (covering an area of about 310 µm 2, one pore with about 5 µm diameter) was observed only in the apical antennomere’s ventral surface ( Fig. 34 ). Around the coeloconic fields, there were no protuberances and cuticular plates, i.e., the surface was smooth. No coeloconic fields were observed in the dorsal part ( Fig. 33 ). Huge (some with the cone longer than 70 µm) modified basiconic sensilla cover the lateral margins of the antennomere, giving the margin a saw-like appearance. Much smaller basiconic sensilla (about 15 µm long cone at the base) are found on the dorsal and ventral surfaces. No multiporous coeloconic fields were observed on the dorsal nor the ventral surface of this antennomere. The segment looks very similar to the widest antennomeres in related Discotettix ( Kuřavová et al. 2017) , except for the absence of the placoid fields, which are present in Discotettix .
