(Figs 1–9)

Dolichopus dorycerus Loew, 1864a: 93 .

Dolichopus hurleyi Runyon, 2008: 368, syn. nov.

Nematode. Apparent Mermithidae .

Demasculinized male examined. Holotype ♂ of Dolichopus hurleyi: USA, Pennsylvania, Centre County, Black Moshannon State Park, Moss-Hanne Trail, Shirks Run, 580 m, 18 June 2007, N 40°53.396′ W78°02.584′, JB Runyon, from vegetation in wooded swamp (USNM) [abdomen partly cut open to reveal mermithid-like nematode within].

Remarks. The demasculinized male has smaller than normal genitalia (cf. Figs 1, 2) that are held off-center beneath abdomen, a less-well developed lamella on arista (cf. Figs 3, 4), wider silvery face (cf. Figs 7, 8), and lacking costal enlargement at apex of R 1. MSSCs of the legs that are lacking include the longer black setae on posterior surface of front femur and the slightly raised, minutely pilose area on posterior surface of the hind tibia (a characteristic of this species group). Notably, the size of lobes of the modified front tarsi are reduced with tarsomere 5 wholly black (mostly white in normal males) (cf. Figs 5, 6). Numerous normal males of D. dorycerus were collected at this site with the single demasculinized specimen.
