Figs 1I–L , 6–7 , 12D

Diagnosis

Viuria lista resembles V. innana sp. nov. in the genitalia pattern but is easily distinguished by the ventral left portion of the tegumen short while in V. innana sp. nov. it is bigger with a spine-like process; both valvae elongated; right ampulla with a dorsal projection and smooth margin while in V. innana sp. nov. the ampulla is smaller than the harpe. Females with the spine-like process of sterigma well developed and sparse when compared with its congeners.

Material examined

BRAZIL • 1 ♂; Rondônia, Ariqueme , 19–20 Mar. 1987; Mielke leg.; OM 14.507 ; OM • 1 ♀; same collection data as for preceding; OM 14.504 ; OM • 1 ♂; Rondônia, Cacaulândia ; 8–19 Nov. 1994; Mielke leg.; OM 39.078 ; OM .

Remarks

After its description, Pachyneuria licisca lista Evans, 1953 had its status elevated to species by Steinhauser (1989), with this interpretation followed until its inclusion in the genus Viuria ( Cong et al. 2019) .

Geographical distribution

Viuria lista is known only from French Guiana ( Evans 1953) and in the state of Rondônia, Brazil ( Fig. 14 ).
