Females with the left portion of the sterigma with a developed process dorsally; the spine-like process is less developed when compared with its congeners.

Remarks Viuria licisca ( Plötz, 1882 ) is the only species of the genus occurring in Central America. Although Moss (1949) reported immatures of V. licisca on Sterculioideae ( Malvaceae ) in Pará , Brazil , no specimen of this species was found at this locality. Janzen & Hallwachs (2009) partially illustrated the immature stages of V. licisca feeding on species of Bytnneria ( Malvaceae ) at the Area de Conservación de Guanacaste , Costa Rica . Geographical distribution Viuria licisca is distributed in Central and northern South America, with records from Mexico , Guatemala , Honduras , Nicaragua , Costa Rica , Panama , Colombia , and Venezuela ( Evans 1953 ) ( Fig. 14 ).
