( Figs 26–38 ) Body creamy. Head sordid white. Crown, pronotum and scutellum without patches ( Figs 26, 28 ). Forewing pale white, without patches on basal half of corium; clavus with one yellow round patch centrally and a brown spot distally; brochosome area with one oblique strip along distal margin and parallel to two other oblique stripes along lateral margin of apical area of corium; RP vein with a brown spot on apical 1/3, 1st apical cell and its adjoining area covered with irregular brownish patches; 3rd apical cell quadrate. Hind wing white and translucent ( Figs 26, 27 ). Male genitalia : Pygofer side brownish black distally; upper lobe strongly pigmented and serrated with several rigid microsetae distally ( Figs 30, 31 ). Subgenital plate with one long macroseta near basal 1/3; three moderate macrosetae arranged longitudinally near apical 1/3; row of fine microsetae extended from basal 1/3 to subapex and two rigid microsetae on apex ( Figs 32, 33 ). Connective slender with central ridge long and lateral arms weakly divergent ( Fig. 34 ). Paramere slender and smooth ( Fig. 35 ). Aedeagus with developed dorsoatrium; aedeagal shaft slim and strongly recurved in lateral view with two pairs of slim apical appendages; dorsal appendages not branched, arched towards outside and pegged by branches of ventral appendages in dorsal view; ventral appendages sinuated with a short protrusion at basal 1/3 and one branch in middle length ( Figs 36–38 ). Specimens examined. Holotype : ♂ , China , Yunnan Prov. , Sanchahe , 7 June 1991 , coll. Rungang Tian . Paratypes : 2 ♂ , same data as holotype ; 1 ♂ , China , Yunnan Prov. , Mengyang, 7 June 1991 , coll. Guangchun Liu and Wanzhi Cai ; 1 ♂ , China , Yunnan Prov. , Yaoqu, 7 June 2009 , coll. Wei Cui. Measurement. Length of male 3.62–3.76 mm (including wing). Etymology. The specific epithet is derived from the Latin word “ dissimilis ”, referring to ventral appendages of aedeagal shaft different from other species in E. ( S. ) robusta group. Remarks. This new species most resembles E. ( S. ) rona in male genitalia, but differs in having the ventral appendages of the aedeagal shaft with a shorter branch at midlength and a small protrusion at basal 1/3 ( Fig. 38 ).
