Dolichopus sporadicus Harmston & Knowlton, 1942: 17

Potential infected species: Dolichopus plumipes (Scopoli, 1763: 334) .

Dolichopus sporadicus was based on one male from Utah, USA. The male face is wide and the hypopygium is small with extremely small cerci. Harmston and Knowlton noted the similarity to D. plumipes (common in Utah) with D. sporadicus differing in lacking a fringe of setae on the middle basitarsus and having small genitalia. Demasculinized specimens of D. plumipes are reported from Europe and have twice been mistakenly described as new species (Kahanpää 2008).
