Dolichopus howjingleei Olejnicek, 2002

MATERIAL EXAMINED. Vietnam: [Lào Cai Province,] Sa Pa env., 22.321° N ,

103.856° E, 1400 m, 19–29.III 2019, 2♂, leg. N. Vikhrev [ ZMUM] .

DISTRIBUTION. Type locality: China: Taiwan, Taipei . New species for Vietnam.

NOTES. The species is the only Oriental Dolichopus species with two stublike wing veins on vein M 1+2 (Olejnicek, 2002; Grichanov, 2016), similar to those in

Lichtwardtia species. One of the males examined has only one (posterior) stump vein on M 1+2. Nevertheless, hind basitarsus of D. howjingleei bears two dorsal seta;

this species has short-haired stylus; the overall habitus and especially the hypopygium morphology distinguish clearly D. howjingleei from Lichtwardtia . Epandrial lobes of the Lichtwardtia hypopygium are greatly reduced, usually to simple or pedunculate ventral setae. In contrast, both distoventral and basoventral epandrial lobes are generally large and strongly projected in Dolichopus species.
