Abstract
Episparis tortuosalis (Moore, The Lepidoptera of Ceylon, L. Reeve Company, London, 1867) (Lepidoptera: Erebidae: Pangraptini) is a significant pest defoliating Chukrasia tabularis plantations in Vietnam. Since 2013 the geographic range of the pest has increased from one to nine provinces. Field surveys in 9 provinces in 2021 showed that feeding by E. tortuosalis larvae resulted in the damage incidence ranging from 28.5 to 100% and the damage index from 0.82 to 3.66. This study illustrates the male and female morphology and genitalia of this pest from Vietnam. Further studies are recommended to help develop an integrated pest management plan for this pest.
