Diagnosis. Dolichopus humilis has an elongated antennal scape and a shortened wing bearing a strong costal callus in males and therefore is referable to the Dolichopus latipennis species group, which presently comprises 13 species (Negrobov et al. 2009; Selivanova & Negrobov 2011). Dolichopus humilis is most similar to D. acutangulus Negrobov et Barkalov, 1976, which is known from Mongolia and Russian Transbaikalia, but differs from D. humilis in the following features: cilia of lower calypter black and postpedicel apically pointed. Female D. humilis keys to arctoboreal D. costalis Frey, 1915 (Negrobov et al. 2009), which differs from D. humilis in entirely black femora and black cilia on lower calypter.
Variability of Dolichopus humilis. Fore femur black-brown except distal third or knee; mid femur brownish-yellow or dirty-yellow, somewhat darker at base; hind femur dirty-yellow, darkened on basal third or entirely pale brown. Mid femur with 1 strong anterior preapical bristle (Negrobov et al. 2009 erroneously mentioned 2 bristles); hind femur with 1–4 (usually 2–3) anterior preapical bristles. Hind tibia more or less conspicuously thickened at basal third and at apex, with 4– 5 anterodorsal, 5–6 dorsal to posterodorsal bristles.
