Frons yellow, anteriorly black, dark part medially concave, posterolaterally with a pair of dark brown dots ( Fig. 29C ). Clypeus yellow with a few setae. Labrum yellow. Maxillary palpus brown, distal segment pale brown. Labial palpus pale yellow, distal segment fusiform and dark brown, distally pale yellow. Mandibles yellowish-brown with distal half dark reddish brown.

Thorax. Pronotum generally pale yellow, anteriorly with a pair of dark brown spots, laterally with two pairs of short dark brown stripes. Intersegmental membrane between pronotum and mesonotum luminous yellow. Mesoprescutum dark brown; mesonotum dark brown; mesoscutellum dark brown, anteriorly pale yellow.

Legs. Generally black, covered with many dark setae. All coxae and femora distally yellow or orange; tibial spurs brown, barely curved; pretarsal claws slightly curved, protruded basally. Foreleg and midleg tibial spur reaching tip of tarsomere 3; hind leg tibial spur reaching base of tarsomere 3, tarsomere 1 longer than that of fore- and midleg ( Fig. 29A ).

Wings. Long ovoid, hyaline with many stripe-like dark brown spots. Forewing as long as hindwing. Pterostigma pale. Forewing costal space with sparse indistinct dark brown dots, a distinct dark brown spot proximad pterostigma; radial area with five relatively large spots; rhegma and marking on basal cubital area indistinct; costal and basal half of posterior crossveins mostly connected by oblique veinlets; five presectoral crossveins present, distal presectoral cells biloculate; RP with nine branches; RP origin basal to MP fork, nearly align at CuA fork. Hindwing costal space hyaline; radial area four small dark brown spots; rhegma as an oblique small dark brown spots; one presectoral crossvein present ( Figs. 24B , 29A ).

Abdomen. Male terga 1–3 generally dark brown. Other parts lost.

Type material. Holotype ♂, CHINA: Yunnan, Yuxi, Huaning County [华÷县], 1800 m, 30.VI.1980, Gegao Zhang ( CAU).

Distribution. China (Yunnan).

Remarks. This species can be distinguished from other species within the E. maculosa group by the pronotum generally pale yellow, anteriorly with a pair of dark brown spots, laterally with two pairs of short dark brown stripes.
