Diagnosis

Male pygofer ( Fig. 3E View Fig ) expanded apically, with two lobes, dorsal lobe larger and subtriagular, apical lobe smaller and rounded. Aedeagus ( Fig. 3J–L View Fig ) with atrial processes slender, parallel and following the curvature of shaft, apex acute; shaft expanded apically, spatulate, with lateral small spiniform projections. Anal tube ( Fig. 3M View Fig ) with triangular basiventral process.

Etymology

The specific epithet is a tribute to Prof. Dr Rodney Ramiro Cavichioli in recognition of his remarkable contribution to our knowledge of the Brazilian Auchenorrhyncha   .

Description

MEASUREMENTS (mm). Holotype (♂): total length 6.8. Paratypes (♂): 6.5–6.8 (n = 6); (♀) 7.1–7.4 (n = 6).

COLORATION. Pale yellow ( Fig. 12C–D View Fig ). Forewing ( Fig. 3D View Fig ) translucent, with three small dark maculae on claval comissure: first, smaller, between base and second anal vein, second, between anal veins, and third on apex of clavus and extending to brachial cell; in some specimens the first pair is absent, and in one specimen, first and second pairs are absent.

HEAD AND THORAX. External morphological characters as in generic description.

MALE TERMINALIA. Pygofer, in lateral view ( Fig. 3E View Fig ), 1.5× as long as maximum height, expanded apically, apical portion higher than basal portion; dorsal margin with prominent preapical subtriagular lobe; ventral tooth broadly rounded; caudal margin with ventral rounded lobe; few small setae scattered on apical half; apical portion with inner integument thickening. Subgenital plate, in lateral view ( Fig. 3F View Fig ), subtriangular, 3.3 × as long as maximum height, slightly expanded medially; in ventral view ( Fig. 3G View Fig ), subrhomboid, lateral margins converging anterad on basal one-fifth and converging towards apex on apical four-fifths; ventral surface with one or two pairs of apical macrosetae; apex slightly truncated. Connective ( Fig. 3H View Fig ) V-shaped, total length approximately ⅔ length of style; stem very short. Style ( Fig. 3H–I View Fig ) with apophysis very elongated and slender; ventral margin distinctly rounded near median third. Aedeagus ( Fig. 3J–L View Fig ) with pair of atrial processes parallel and following curvature of shaft, each process approximately ½ length of shaft, broad at base and tapering towards acute apex; shaft slightly flattened dorsoventrally, apical portion expanded laterally, spatulate, lateral margins with some small spiniform projections. Anal tube ( Fig. 3M View Fig ) with sternite X long and tubular, with triangular basiventral process with denticles.

FEMALE TERMINALIA. Sternite VII ( Fig. 4A–C View Fig ) as long as wide; posterior margin slightly excavated medially. First valvula of ovipositor ( Fig. 4F View Fig ) with dorsal sculptured area areolate-strigate. Other characters as in generic description.

Remarks

Takiyaella cavichioli   gen. et sp. nov. is most similar to T. sexguttata ( Chiamolera & Cavichioli, 2003)   gen. et comb. nov. by the shape of male pygofer with two lobes, one dorsal and one apical ( Figs 3E View Fig , 10D View Fig ) and the shape of the aedeagal shaft expanded apically, with lateral margins rounded, bearing several small spiniform projections ( Figs 3J–L View Fig , 10I–J View Fig ). However, T. cavichioli   gen. et sp. nov. differs in having the style slender and the aedeagus with atrial processes parallel to the shaft and following its curvature ( Fig. 3J View Fig ), while in T. sexguttata   gen. et comb. nov. the style is wider, and the atrial processes are shorter, not parallel to the shaft ( Fig. 10I View Fig ).
