Qin, Huimin, Kang, Juxia, Huang, Min & Zhang, Yalin, 2020, On the Oriental leafhopper genus Takagioma Thapa, 1989 (Hemiptera: Cicadellidae: Typhlocybinae: Dikraneurini) with descriptions of six new species, Zootaxa 4742 (2), pp. 299-310 : 301

Takagioma rostra Qin and Huang sp. nov.

( Figures 5–8 , 32–39 )

Measurement. Male, 2.50–2.72mm (including wing).

Description. Body yellowish with whitish stripe thin on vertex; eyes gray; pronotum with a brown triangle patch centrally; scutum and scutellum ochraceous. Face brown with apical margin beige and deepen downward. Forewing infuscate with white stripe broader than in other species, veins yellowish; hind wing with CuA branched.

Abdominal apodeme weakly developed ( Fig. 36 ). Pygofer hook extremely long in dorsal view and extending caudad ( Fig. 32 ). Subgenital plate triangular with 4 macrosetae ( Fig. 35 ). Paramere slender with both ends acuminate, central part with airfoil-like lobe ( Fig 39 ). Connective with central lobe well developed and extended obviously beyond lateral feet. Aedeagal shaft stout and slightly arched in lateral view with abruptly narrowed apex; dorsoatrium developed ( Figs 37, 38 ).

Examined type materials. Holotype: Male, CHINA, Yunnan Province, Xishuangbanna , 100.90°E, 22.03°N, 8 July 2017, coll. Weijian Huang. Paratype: 2 Male, collect data same as holotype .

Notes. The new species is similar to Takagioma silvicola Dworakowska, 1993 in the aedeagus, but can be distinguished from the latter by the relatively thick aedeagal shaft and extremally long pygofer hook.

Etymology. The specific epithet is derived from Latin prefix “ rostr- ”, which refers to the resemblance of the aedeagal shaft apex to the bill of a bird.
