Diagnosis

Male pygofer ( Fig. 7E ) expanded apically, with two lobes, a larger dorsal lobe and a smaller subacute apical lobe. Aedeagus ( Fig. 7J–K ) with atrial processes bifid, dorsal ramus about 3 × as large as ventral ramus, both acute. shaft expanded laterally forming small process on each side.

Etymology

The specific epithet is a tribute to Prof. Dr Daniela Maeda Takiya in recognition of her remarkable contribution to our knowledge of the Brazilian Auchenorrhyncha , and also in gratitude for her great friendship and for bringing the first author to the study of leafhoppers. The species epithet is treated as a noun in apposition.

Description

MEASUREMENTS (mm). Holotype (♂): total length 6.5. Paratypes (♂): 6.3–6.6 (n = 2).

COLORATION. Pale yellow ( Fig. 12G–H ). Forewing ( Fig. 7D ) translucent, with three small 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. 7E ), 1.8 × as long as maximum height, expanded apically; dorsal margin with prominent preapical lobe; caudal margin with ventral subacute lobe; ventral tooth broadly rounded; apical portion with inner integument thickening. Subgenital plate, in lateral view ( Fig. 7F ), subtriangular, 2.9 × as long as maximum height; in ventral view ( Fig. 7G ), subovoid, lateral margins converging towards apex; ventral surface with pair of uniseriate rows of 3–4 macrosetae; apex acute. Connective ( Fig. 7H ) V-shaped, total length approximately ⅔ length of style; stem very short. Style ( Fig. 7H–I ) with apophysis elongated and robust. Aedeagus ( Fig. 7J–K ) with pair of bifid atrial process: dorsal ramus about ⅓ length of shaft, directed dorsally, anterior to curvature of shaft; ventral ramus approximately ⅓ length of dorsal ramus, directed posteriorly, posterior to curvature of shaft; shaft tubular, slightly flattened dorsoventrally at apex, ventral surface with longitudinal row of denticles on each side, extending from base to apex, apical portion expanded laterally forming small process on each side. Anal tube ( Fig. 7E ) with sternite X long and tubular, without basiventral process.

FEMALE TERMINALIA. Female unknown.

Remarks

Takiyaella daniela gen. et sp. nov. is easily distinguished from other species of the genus by having atrial process bifid apically ( Fig. 7J–K ).
