Diagnosis
Viuria acadia sp. nov. is distinguished from other species of Viuria by the combination of the following genitalic characteristics: the ventral left portion of the tegumen is similar to that of V. herophile and V. licisca but shorter; the left and right valvae with ampulla triangled distally while in V. herophile the left valva is rounded and in V. licisca the right one is rounded. Females with papilla analis truncated ventrally; the spine-like process of the sterigma is smooth, differing from its congeners.
Etymology
The specific epithet refers to the Akkadian Empire, the first ancient empire of Mesopotamia.

Description
Head, thorax, wings and abdomen as in other species of Viuria.

Tegumen squared, with latero-ventrally asymmetrical expansions; left expansion sinuous with margin serrated; uncus asymmetrical, apical portion slightly inclined downwards and rounded; gnathos as transversal plate lightly sclerotized. Valvae asymmetrical; left valva with harpe 2× as long as wide, with dorsal margin serrated and curved inwards, ampulla rounded, with posterior margin smooth; right valva shorter than left valva, harpe with median-dorsal rounded projection, ampulla rounded. Aedeagus cylindrical, vesica and aedeagus opening dorsally, distal portion left curved and serrated ventrally.
