Separating Pachyodes haemataria and Pachyodes ornataria:

Forewing upperside: basal lines are closer together in ornataria, resulting in a narrower olive band compared to haemataria. Hindwing upperside: cell streak smaller in ornataria, sometimes red to reddish-black. In haemataria, the long cell streak is prominent, black and straight. Underside: Pachyodes ornataria has diffused blackish-brown markings near the base of both wings, which haemataria lacks. On the forewing underside, ornataria lacks the prominent black mid-cell and postdiscal spots present in haemataria. On the hindwing underside, ornataria has a black discal spot (somewhat diffused), which haemataria lacks.
