Diagnosis

Viuria herophile resembles V. licisca in the genitalia pattern but is easily distinguished by the ventral left portion of the tegumen thin and rounded while in V. licisca curved inwards; left valva with ampulla rounded and well-developed, and harpe dorsally serrated, while in V. licisca the ampulla is truncated; right valva with harpe rounded dorsally, while in V. licisca the harpe has a spine-like process curved inwards; distal portion of aedeagus left curved, while in V. licisca curved upwards. Females with the right portion of the sterigma expanded ventrally, while in V. licisca the left portion of the sterigma has a developed process dorsally.

Taxonomic remarks

Evans (1953) considered Pellicia herophile Hayward, 1940 as a subspecies of Pachyneuria licisca Plötz, 1882 . Later, Steinhauser (1989) elevated its status as a species of Pachyneuria , and this taxonomy has been followed until the description of the genus Viuria ( Cong et al. 2019) .

Geographical distribution

Viuria herophile is distributed in the Amazon basin, with records from Ecuador, Peru, and Brazil ( Fig. 14 ). Evans (1953) also cited the occurrence of V. herophile in the state of Minas Gerais, Brazil, and in Paraguay, but these specimens were not examined in the present study.
