Morphology-based identification
Zeugodacus depressus can be identified reliably based on morphological characters. Spot characters are the two pairs of setae on the scutellum and an infuscation around vein CuA1.
Molecular identification
COI sequence data can be used to identify

Distribution
Zeugodacus depressus is one of the few Dacini that has adapted to a temperate climate and has been recorded as far North as Hokkaido in Japan, and can be found in Korea, China and Taiwan. Its native range is unclear.
