Ngirhaphium

Ngirhaphium is a genus of flies in the family Dolichopodidae. It includes six species known from mangroves in Southeast Asia. Ngirhaphium closely resembles the genus Rhaphium and was originally placed in the subfamily Rhaphiinae, though several molecular phylogenetic analyses were unable to resolve its phylogenetic position. The genus is named after Peter Kee Lin Ng, a professor at the National University of Singapore; the genus name combines the family name "Ng" and the generic name Rhaphium.
