Diagnosis

Viuria inanna sp. nov. resembles V. lista in the genitalia pattern but is easily distinguished by the ventral left portion of the tegumen with a spine-like process while absent in V. lista ; right valva with ampulla smaller than harpe while in V. lista the valva has a dorsal projection and smooth margin. Females with papilla analis moon-shaped; the spine-like process of sterigma is covered by small setae.

Etymology

The specific epithet refers to the ancient Mesopotamian goddess of love, war, and fertility, also known as the Queen of Heaven. Inanna was associated with the planet Venus, being related to beauty, sex, divine justice, and political power.
