Abstract 
Scarlata namsanam sp. nov. from Laos is described and illustrated. The type series was collected on wet soil near the drying stream within a primary monsoon lowland tropical forest. This new species is most similar to S. guichardii Skowron Volponi, 2022, from which it differs in the coloration of the hind tibia, forewing and abdomen and in noticeably wider discal spot of the hindwing.
