Helmablatta Vidlička, Vršanský et Deharveng , gen. n.

Type species: Helmablatta louisrothi Vidlička, Vršanský et Deharveng , sp. n. designated below by monotypy.

Diagnosis. Differing from all living and fossil cockroach species in the presence of body modifications, mainly feature of tergal gland, tergal unpaired growth and excisions on both wing pairs.

Cavernicolous. Spelaeoblatta -like. Male: Small, pale, eyes present but reduced. Tegmina abbreviated, lacking venation (only Sc allusively visible), apical half sinuous. Hind wings partly reduced, lacking venation, deep incision in apex. Abdomen short, abdominal tergal gland very well developed, composite of the three segments, T3-T5. Tergite 8 with large central anteriorly incurved hook. Legs long, coxae and femora robust, pulvilli and arolia absent, tarsal claws simple, symmetrical. Anteroventral margin of front femur with alternate large and small spines irregularly disposed and a large distal spine.

Etymology. Helmablatta after the shape of tergal gland, suggesting helmet (Slavic “helma”) and cockroach genus name Blatta .
