It is not possible here to prove conclusively this is Pithauria murdava.
P. murdava is a species that flies from India to Indochina.
It is not known from peninsular Thailand.
Old record sugesting its presence in P. Malaysia and Borneo are not confirmed.
Over the years of collecting in P. Malaysia no specimen of P. murdava was known.
Each species is very variable.
The male P. stramineipennis specimen is readily identiafiable.
The upperside is clothed with straw-coloured hair and the UnF have a large pale area. https://www.gbif.org/occurrence/2456362148
