Aedeagus ( Fig. 8J–K ) with atrial processes large, flattened laterally, directed caudally and bent dorsally; shaft short, flattened laterally on basal half and dorsoventrally on apical half, apex expanded with laterodorsal spiniform projections. Anal tube ( Fig. 8E ) with basal portion produced anteroventrally bearing moderately long basiventral acute teeth. Etymology The specific epithet is a tribute to Prof. Dr Gabriel Mejdalani in recognition of his remarkable contribution to our knowledge of the Brazilian Cicadellidae .

Holotype ( ♂ ): total length 6. Paratypes ( ♂ ): 6.0–6.5 (n = 4); ( ♀ ) 6.8–6.9 (n = 2). COLORATION. Pale yellow ( Fig. 12I–J ). Forewing ( Fig. 8D ) translucent, with three dark maculae on claval comissure: first, between base and second anal vein; second, between anal veins and third on apex of clavus and extending to brachial cell. HEAD AND THORAX. External morphological characters as in generic description. MALE TERMINALIA. Pygofer, in lateral view ( Fig. 8E ), 1.3 × as long as maximum height, strongly expanded apically, apical portion twice as high as basal portion; dorsal margin slightly concave medially; caudal margin truncated with small ventral rounded lobe; ventral tooth slightly rounded; apical portion with inner integument thickening. Subgenital plate, in lateral view ( Fig. 8F ), subtriangular, 2.6 × as long as maximum height, narrowing at apical fourth; in ventral view ( Fig. 8G ), cordiform, lateral margins converging towards apex; ventral surface with pair of uniseriate rows of 2–3 macrosetae; apex acutely rounded. Connective ( Fig. 8H ) V-shaped, total length approximately ⅔ length of style; stem short. Style ( Fig. 8H–I ) with dorsal margin of apodeme rounded; apophysis elongated and robust. Aedeagus ( Fig. 8J–K ) with pair of large atrial processes, approximately ½ length of shaft, flattened laterally, posterior to curvature of the shaft, directed caudally and bent dorsally, wide at base and narrowing towards acute apex; shaft short, flattened laterally on basal half and dorsoventrally on apical half; apex slightly expanded with 2–3 pairs of laterodorsal spiniform projections. Anal tube ( Fig. 8E ) with sternite X long and tubular, basal portion produced anteroventrally bearing moderately long basiventral acute teeth. FEMALE TERMINALIA. Sternite VII ( Fig. 9A–C ) slightly wider than long; lateral margins parallel. First valvula of ovipositor ( Fig. 6F ) with dorsal sculptured area areolate-strigate. Other characters as in generic description. Remarks Takiyaella mejdalanii gen. et sp. nov. resembles T . cavichiolii gen. et sp. nov. and T . sexguttata gen. et comb. nov. by the apical portion of the aedeagus with lateral spiniform projections ( Figs 3K , 8K , 10J ). However, T . mejdalanii gen. et sp. nov. differs from other species of the genus by the shape of the male pygofer, strongly expanded apically ( Fig. 8E ) and by the shape and direction of the atrial processes of the aedegus ( Fig. 8J–K ).
