Irenaneura bifurcata, Yanghui, Cao, Min, Huang & Yalin, Zhang, 2012

Yanghui, Cao, Min, Huang & Yalin, Zhang, 2012, Irenaneura, a new leafhopper genus from China (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini), with description of four new species, Zootaxa 3333, pp. 58-65 : 63-64

4. Irenaneura bifurcata sp. nov. ( Figs 7, 11 , 44–52 )

Description: Vertex, face and mesonotum sordid light brownish, midline of frontoclypeal area lightened, apical 2/ 3 of anteclypeus dark brown. Coloration of forewing as in I. longiprocessa . ( Figs 7, 11 )

Male dorsal appendage slightly curved dorsad ( Fig. 45 ). Subgenital plate broadened subbasally, provided with 3 irregular rows of microsetae marginally, outer microsetae distinctly blunter than the inner ones; distal row of microsetae with several basal ones thickened ( Fig. 47 ). Style apical dorsal branch with subapical tooth short and acute, apical tooth indistinct; basal part broadened ( Figs 48, 49 ). Connective somewhat triangular, with two arms long ( Fig. 50 ). Aedeagal shaft with apical part slightly broader than base, ornamented with dense minute teeth over distal half, with pair of bifurcate preatrial processes arising away from shaft; preatrium and dorsal apodeme large ( Figs 51, 52 ).

Measurement: Male length 1.0mm (anterior dorsum length, excluding wing).

Material examined: Holotype: 3, CHINA, Yunnan Prov., Ruili, Mengxiu, 2-v-1981, coll. Yang Jikun. ( CAU).

Diagnosis: Similar to I. dworakowski , but with different shape of connective, and aedeagus with dorsal apodeme well developed, preatrial processes arising far from shaft, with dorsal branch much thicker than ventral one. Etymology: The specific epithet is derived from Latin prefix “bi-” and Latin word “furcatus” which refers to shape of preatrial processes of aedeagus.
