Note. Bactrocera dorsalis is part of a species complex whose composition and limits continue to be disputed among taxonomists. Bactrocera invadens Drew, Tsuruta & White, 2005 ; B. papayae Drew & Hancock, 1994 ; and B. philippinensis Drew & Hancock, 1994 were considered to be synonyms by Schutze et al., 2015), whereas Drew & Hancock (2022) recently resurrected B. invadens and B. papayae , based on morphological structures of the male genitalia. Maneesh et al. (2022) stated that B. invadens has been definitively recorded in the Himalayan region from Bhutan ( Drew et al., 2007) and Nepal (Leblanc et al., 2019: as B. dorsalis ). In this article, we use the name B. dorsalis because our material does not possess morphological characters given as diagnostic for B. invadens at Drew & Hancock 2022.
