This species is identical to Euwallacea n. sp. 5 and can only reliably be identified with molecular data. Without molecular data it can be distinguished by its distribution primarily in submontane forests of the Himalayas (E. n. sp. 5 occurs in lowland forests) and by the elytralstrial punctures not colored differently than the rest of the elytra (E. n. sp. 5 typically has unique coloration of the elytralstriae, which are dark brown in mature specimens, making the punctures appear very distinctive and obvious. This species is nearly identical to E. fornicatusspecies complex and can be separated by the elytralbases weakly carinate and posterolateraldeclivitalcostagranulate.
