Diagnosis

Male pygofer ( Fig. 8E View Fig ) strongly expanded apically, with apical lobe. Aedeagus ( Fig. 8J–K View Fig ) 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 View Fig ) 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   .

Description

MEASUREMENTS (mm). Holotype (♂): total length 6. Paratypes (♂): 6.0–6.5 (n = 4); (♀) 6.8–6.9 (n = 2).

COLORATION. Pale yellow ( Fig. 12I–J View Fig ). Forewing ( Fig. 8D View Fig ) 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 View Fig ), 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 View Fig ), subtriangular, 2.6 × as long as maximum height, narrowing at apical fourth; in ventral view ( Fig. 8G View Fig ), cordiform, lateral margins converging towards apex; ventral surface with pair of uniseriate rows of 2–3 macrosetae; apex acutely rounded. Connective ( Fig. 8H View Fig ) V-shaped, total length approximately ⅔ length of style; stem short. Style ( Fig. 8H–I View Fig ) with dorsal margin of apodeme rounded; apophysis elongated and robust. Aedeagus ( Fig. 8J–K View Fig ) 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 View Fig ) with sternite X long and tubular, basal portion produced anteroventrally bearing moderately long basiventral acute teeth.

FEMALE TERMINALIA. Sternite VII ( Fig. 9A–C View Fig ) slightly wider than long; lateral margins parallel. First valvula of ovipositor ( Fig. 6F View Fig ) 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 View Fig , 8K View Fig , 10J View Fig ). 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 View Fig ) and by the shape and direction of the atrial processes of the aedegus ( Fig. 8J–K View Fig ).
