Wang, Xu, He, Zhiqiang & Wei, Cong, 2017, A new species of Cicadatra Kolenati, 1857 from China, with primary phylogenetic analyses of the tribe Cicadatrini (Hemiptera: Cicadidae), Zootaxa 4242 (1), pp. 174-184 : 179

Genus Emathia Stål, 1866

Emathia Stål, 1866: 8 . Type species: Emathia aegrota Stål, 1866 .

Cicadalna Boulard, 2006: 529 . syn. n. Type species: Cicadalna takensis Boulard, 2006 .

Diagnosis. Head about as long as pronotum, including eyes about as wide as base of mesonotum. Rostrum almost reaching the posterior coxae. Pronotum a little shorter than mesonotum, with barely developed lateral margin, not amplified. Abdomen short, about as long as forebody. Timbal covers incomplete, narrow and exposed inwardly; male opercula small, not extending beyond posterior margin of abdominal sternite II. Wings hyaline, with 8 and 6 apical cells on fore wing and hind wing, respectively.

Remarks. The genus Cicadalna was erected by Boulard (2006) for the type species, Cicadalna takensis . Later, the same authour reviewed Cicadalna and placed it in the tribe Cicadini of the subfamily Cicadinae ( Boulard 2013) . However, the incomplete timbal covers, small opercula, shape of male genitalia and wing venation are inseparable between Cicadalna from Emathia , and no other sound morphological characters are available to separate these two genera. Accordingly, Cicadalna is treated here as a junior synonym of Emathia .
