( Figs 117 View Figs 106–117 , 143, 144 View Figs 126–144 , 149–152 View Figs 145–152 )

Etymology. This species is named after the Cusco Department of Peru where it was collected.

Material. Holotype – male, PERU: Cusco Department , 7 km NE of Mandor, 13 º 18.7' S, 70 º 49.5' W, 890 m, 1–3 December 2010, V. Sinyaev, S. Sinyaeva, Yu. Bezverkhov ( ZIN) GoogleMaps . Paratypes: 2 males, same data as for holotype ( ZIN) GoogleMaps .

Description. Male (holotype).Size and coloration of body practically as in E. unilobatum sp. nov. but with following differences: coloration greenish with yellowish head having almost whitish dorsum and genae under posterior halves of eyes, with whitish longitudinal median stripe on pronotal disc and anteroventral stripe on each lateral pronotal lobe (latter stripe almost as in E. unilobatum sp. nov.; Fig. 117 View Figs 106–117 ), and with light brown to brown clypeus and labrum; external structure also very similar to that of this species ( Figs 149–151 View Figs 145–152 ), but pronotal lateral lobes slightly less high ( Fig. 117 View Figs 106–117 ), stridulatory vein of left tegmen approximately 5.5 mm in length and with about 170 ventral teeth ( Fig. 152 View Figs 145–152 ), middle tibia hardly less widened, posteromedian process of last tergite weekly widening to widely bilobed apex (this apex with a pair of roundly angular tubercles directed backwards/downwards, and with widely rounded and not deep notch between these tubercles), posterior edges of last tergite around this process with a pair of very short obtuse-angled projections ( Fig. 143 View Figs 126–144 ), and genital plate with small but distinct styli ( Fig. 144 View Figs 126–144 ).

Variations. Coloration with light brown clypeus and yellowish labrum, or with light brown labrum and yellowish clypeus, as well as sometimes with rather wide yellowish band along stems of tegminal Sc and R (and around them) in proximal half of each tegminal lateral field; posterior edges of last tergite around posteromedian process with small spinule-like projections or without distinct projections; genital plate sometimes with very small and almost indistinct styli.

Female unknown.

Length in mm. Body 32–34; body with wings 68– 72; pronotum 9–10.5; tegmina 58–61; hind femora 28–30.

Comparison. The new species is clearly distinguished from E. unilobatum sp. nov. and E. diasae by a distally wider and apically bilobed posteromedian process of the male last tergite (vs: this process in the dorsal view is narrowing to an almost spine-like apical part; compare Figs 138, 140 and 143 View Figs 126–144 ).
