Parahercostomus is a genus of flies in the family Dolichopodidae. It includes four species known only from China.[3] Members of the genus are metallic green in color and large in size, with a body length of 4.5–5.3 mm and a wing length of 5.2–7.0 mm. The generic name is a combination of the prefix para- (from the Ancient Greekπαρά, pará, meaning "near" or "beside") with the generic name Hercostomus.[1] According to Brooks (2005)'s phylogenetic analysis of the subfamily Dolichopodinae, Parahercostomus appears to be closely related to Grichanov (1999)'s Afrotropical species group 1 in the genus Hercostomus, which was later transferred to the genus Afrohercostomus.[4]
