Improving knowledge on Viviania linostigma, a threatened species from southern Brazil

Viviania linostigma is restricted to the Brazilian territory, considered a threatened and endemic species of a small region in the Araucaria Forest. This species has been recorded only in southeast Santa Catarina State, and the extreme northeast of Rio Grande do Sul State, in Brazil. Here, we report four new records of V. linostigma for Rio Grande do Sul, expanding its known distribution by 262 km to the south and improving knowledge about the conservation status of the species. These novelties reinforce that species conservation requires more investment in fieldwork, especially in little sampled regions.
