Remarks.

This species had been sunk as a synonym of Prochasma dentilinea by Prout (1927), but was restored to a valid species by Sato (2019). Specimens from Vietnam, Laos and Thailand identified as conspecific with P. squalida in Sato (2019, 2020) were separated and treated as a new species, P. parasqualida in Sato (2023).
