Diagnosis
The female of Andromma helix sp. nov. is characterized by the epigyne with small transversely oval copulatory openings with helicoidal copulatory ducts visible in transparency.
Etymology
The species name is a noun in apposition, referring to the shape of the copulatory ducts which are helicoidally wound ( Fig. 27E–F View Fig ).
