Scale bars: 0.1 mm. Description. Male. (n = 1): Body length 12 mm, wing length 13 mm, antenna length 3 mm. Head ( Figs 5 , 11 ). Brownish yellow with pale gray pruinosity except orbit pale yellow. One median tubercle between eyes. Setae on head black. Scape and pedicel brown, flagellum 13-segmented with two basal segments fused, fusion-segment yellow, succeeding segments brown, flagellomeres cylindrical, apical segments elongate, with longer verticils. Proboscis brownish yellow with black setae; palpus blackish brown with black setae. Thorax ( Figs 5 , 11 ). Generally brown with pale gray pruinosity. Pronotum brownish yellow with one dark blackish brown stripe. Prescutum brown with two brownish yellow stripes, one yellow line at middle. Scutum yellow. Scutellum and mediotergite brownish yellow. Pleura brown, variegated by light yellow areas. Setae on thorax brown. Coxae and trochanters yellow; femora yellow with two dark brown rings, first at basal 2/3, second at tip, broader; tibiae brown with one spur; tarsi brown. Setae on legs brown except coxae and trochanters with brownish yellow setae. Wing ( Figs 5 , 15 ). Brownish hyaline with conspicuous brown pattern, chiefly spotted, with narrow dark brown margin, brownish hyaline areas large. Base of wing brown, connected with two large ocellate circles with flattened tips; one circle along cord connected with second circle. Stigma solidly dark brown. Origin of Rs obtuse and curved with short spur; R2+3+4 longer than R2+3; m-cu at basal 1/3 of cell dm. Halter 2.1 mm long, brown except base of stem and apex of knob pale yellow. Setae on wings brownish yellow. Abdomen ( Fig. 5 ). Tergites 1-3 brownish yellow; tergites 4-9 brownish black, with one brownish yellow middle line. Sternites 1-5 brownish yellow; sternites 6-9 brownish black. Setae on abdomen brownish yellow. Hypopygium ( Figs 34-39 ). Posterior margin of tergite 9 ( Figs 34 , 37 , 38 ) with flat and subtrigonal lobe on each side of median V-shaped notch. Tip of outer gonostylus ( Figs 35 , 37-39 ) curved into spine. Inner gonostylus ( Figs 36-39 ) relatively longer, with tip obtuse and curved up. Interbase ( Figs 38 , 39 ) with long and slender rod beyond base, little longer than gonocoxite, whole slender rod straight, tip spine-like. Aedeagus ( Figs 38 , 39 ) very stubby, 4/5 as long as gonocoxite. Female. (n = 5): Body length 11.0-14.0 mm, wing length 11.5-13.5 mm, antenna length 2.7-3.2 mm. Similar to male. Cerci and hypovalves reddish brown ( Fig. 6 ). Figures 22-27.

Scale bars: 0.1 mm. Type Material. Holotype male (CAU), China: Guizhou, Tongren, Fanjingshan, 2002.VI.1, Ding Yang. Paratypes : 2 females (CAU), China: Guizhou, Tongren, Fanjingshan, 2002.VI.1, Ding Yang; 1 female (CAU), China: Guizhou, Tongren, Fanjingshan, 2002.V.29, Ding Yang; 2 females (CAU), China: Guizhou, Tongren, Fanjingshan, 2002.V.31, Ding Yang. Distribution. China (Guizhou). Etymology. The specific name refers to the long aedeagus. Remarks. This new species is somewhat similar to E. (E.) elongatum Mao & Yang, 2009 from China (Yunnan) in having the similar femora and wing pattern, but can be separated from E. (E.) elongatum by the interbase rod being straight and the aedeagus stubby and 4/5 as long as the gonocoxite. In E. elongatum , the interbase rod is finger-shaped, and the aedeagus is slender and half as long as the gonocoxite ( Mao and Yang 2009 ). Figures 28-33.
