Diagnosis

Male pygofer ( Fig. 5E View Fig ) expanded apically, with apical lobe. Aedeagus ( Fig. 5J–K View Fig ) with two pairs of slender atrial processes anterior to shaft curvature, one pair curved dorsally, and the second directed ventrally; shaft with apical portion expanded laterally forming a small process on each side; anal tube ( Fig. 5L View Fig ) with basiventral process truncated with few denticles.

Etymology

The specific epithet is a tribute to Prof. Dr Ana Paula Coelho-Marques in recognition of her remarkable contribution to our knowledge of the Brazilian Auchenorrhyncha   , mainly in the study of neocoelidiines.

Material examined

Holotype BRAZIL • ♂; Rio de Janeiro, Nova Friburgo, Macaé de Cima ; alt. 1250 m; Nov.–Dec. 2009; [P.C.] Grossi leg.; DZUP-083605; DZUP.  

Paratypes BRAZIL – Rio de Janeiro • 1 ♂, 2 ♀♀; same collection data as for holotype; DZUP-083606; DZUP   1 ♂, same collection data as for holotype; DZRJ-AUCH #242; DZRJ   1 ♀; same collection data as for holotype; DZRJ-AUCH #243; DZRJ   .

Description

MEASUREMENTS (mm). Holotype (♂): total length 6.3. Paratypes (♂): 6.2–6.5 (n = 2); (♀) 6.9–7.1 (n = 3).

COLORATION. Pale yellow ( Fig. 12E–F View Fig ). Forewing ( Fig. 5D 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.

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

MALE TERMINALIA. Pygofer, in lateral view ( Fig. 5E View Fig ), 1.7 × as long as maximum height, expanded apically, apical portion higher than basal portion; dorsal margin slightly concave medially; ventral tooth slightly rounded; caudal margin truncated with small ventral rounded lobe; few small setae scattered near ventral margin and apical half; apical portion with inner integument thickening. Subgenital plate, in lateral view ( Fig. 5F View Fig ), subtriangular, 3.3 × as long as maximum height; in ventral view ( Fig. 5G View Fig ), subovoid, lateral margins converging towards apex; ventral surface with pair of uniseriate rows of 5–6 macrosetae; apex acutely rounded. Connective ( Fig. 5H View Fig ) V-shaped, total length approximately ⅔ length of style; stem very short. Style ( Fig. 5H–I View Fig ) with dorsal margin of apodeme broadly rounded; apophysis elongated and robust. Aedeagus ( Fig. 5J–K View Fig ) with two pairs of slender atrial processes with acute apexes: first more dorsal in comparison to second, longer, approximately ⅓ ength of shaft, curved dorsally, anterior to shaft curvature; second pair, shorter, approximately ⅓ length of first, directed ventrally; 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. 5E, L View Fig ) with sternite X long and tubular, with basiventral process truncated, with few denticles. FEMALE TERMINALIA. Sternite VII ( Fig. 6A–C View Fig ) as long as wide; lateral margins constricted medially. First valvula of ovipositor ( Fig. 6F View Fig ) with dorsal sculptured area baculiform. Other characters as in generic description.

Remarks

Takiyaella coelhomarquesae   gen. et sp. nov. is most similar to T. daniela   gen. et sp. nov. by the shape of apex of aedeagus expanded laterally forming a small process on each side ( Figs 5K View Fig , 7K View Fig ). However, T. coelhomarquesae   gen. et sp. nov. differs by the dorsal margin of the male pygofer without distinct lobe ( Fig. 5E View Fig ); aedeagus with two pairs of atrial processes ( Fig. 5J View Fig ) and anal tube with basiventral process ( Fig. 5L View Fig ). While T. daniela   gen. et sp. nov. have the dorsal margin of the male pygofer with distinct lobe ( Fig. 7E View Fig ); aedeagus with a pair of bifid atrial processes ( Fig. 7J View Fig ) and anal tube without basiventral process ( Fig. 7E View Fig ).
