Description. Vertex brownish yellow, with two brown irregular markings at sides of coronal suture ( Figs 1, 3 ). Face brownish yellow, relatively long, with brown anteclypeus oval-shaped ( Fig. 4 ). Pronotum mostly brown, showing yellow color near anterior margin ( Figs 1, 3 ). Scutellum yellow with black apex ( Figs 1, 3 ). Forewing semitransparent, light brownish yellow.

Abdominal apodemes small, not extended beyond hind margin of 3rd sternite ( Fig. 9 ).

Male genitalia. Pygofer lobe with scattered microsetae at upper edge and near lower margin ( Fig. 10 ). Subgenital plate broadened subbasally, provided with two long macrosetae on lateral surface, numerous peg-like setae along dorsal margin from subbase to near middle part; several microsetae scattered on apical portion ( Fig. 11 ). Style expanded and truncate at apex with two points subequal in size ( Fig. 12 ). Aedeagal shaft widened and compressed in lateral view, with pair of slender basal processes extended dorsad of shaft and slightly shorter than shaft; gonopore subapical on ventral surface ( Figs 13, 14 ). Connective nearly Y-shaped, central lobe distinct, lateral arms sturdy ( Fig. 15 ).

Female genitalia. Female 7th sternite as in Fig. 16 . Valvula I curved dorsad, blade-like apically, with apex finely striated dorsally ( Fig. 19 ). Valvulae II slightly sinuous, downturned apically, right blade with tiny teeth at apical part dorsally ( Fig. 20 ). Valvula III with apex round, dorsal margin and apex surface with many small setae ( Fig. 21 ).

Specimen examined. Holotype: ♂, CHINA, Guizhou Prov., Maolan, Wengang , 20 IX 2018, coll. Xiaoxiao Chen, Chao Tao, Xiaowei Yuan & Zhouwei Yuan. Paratypes: 30♂♂, 30♀♀, same data as holotype .

Measurement. Body length ♂ 2.3~2.5 mm; ♀ 2.7~2.9 mm.

Remarks. This species is similar to E. dubiosa Dworakowska (1980) , but can be distinguished from the latter by the aedeagal shaft margin without serrations near the apex, the subapical gonopore and the shape of the pygofer dorsal appendage, and by the connective with the central lobe relatively narrow and lateral arms longer.

Etymology. The new species is named after its type locality, Wengang, Guizhou Province.
