Diagnosis

Forewing ( Fig. 1D View Fig ) with three dark maculae, two on clavus and one on fourth apical cell. Male pygofer ( Fig. 1E View Fig ) rectangular, not expanded apically. Connective ( Fig. 1H View Fig ) Y-shaped. Aedeagus ( Fig. 1J–K View Fig ) with atrial processes slender, directed posterad, with three spiniform projections; shaft flattened laterally, not expanded apically.

Etymology

The specific epithet alludes to the singular set of morphological characteristics of this species.

Description

MEASUREMENTS (mm). Holotype (♂): total length 6.2. Paratypes (♂): 6.1 (n = 1); (♀) 6.7 – 6.8 (n = 2).

COLORATION. Pale yellow ( Fig. 12A–B View Fig ). Forewing ( Fig. 1D View Fig ) yellow, translucent, with three dark maculae: first on claval comissure between anal veins, second on apex of clavus and extending to brachial cell, and third on fourth apical cell.

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

MALE TERMINALIA. Pygofer, in lateral view ( Fig. 1E View Fig ), 1.6 × as long as maximum height, not expanded apically, basal portion slightly higher than apical portion; dorsal margin slightly convex; ventral tooth

prominent and rounded; caudal margin truncated; few small setae scattered on middle third. Subgenital plate, in lateral view ( Fig. 1F View Fig ), 2.9 × as long as maximum height, expanded medially; dorsal margin slightly convex; ventral margin oblique in the apical half; apical third strongly narrowed; in ventral view ( Fig. 1G View Fig ), subtriangular, lateral margins parallel on basal half and strongly converging on apical half; ventral surface with pair of uniseriate rows of 5–6 macrosetae; apex acute. Connective ( Fig. 1H View Fig ) Y-shaped, total length about 3 /5 length of style; stem approximately as long as arms. Style ( Fig. 1H– I View Fig ) with dorsal margin of apodeme broadly rounded, ventral margin acutely produced anteroventrally; apophysis elongated, robust. Aedeagus ( Fig. 1J–K View Fig ) with pair of slender atrial processes, each process with approximately half length of shaft, directed posterad and strongly divergent in ventral view, apical third with three spiniform projections, one longer on dorsal margin, and two smaller on apex; shaft flattened laterally, curved dorsally at basal third, with pair of small subapical ventral lamellae. Anal tube ( Fig. 1E View Fig ) with sternite X long and tubular, without basiventral process.

FEMALE TERMINALIA. Sternite VII ( Fig. 2A–C View Fig ) 1.2 × as long as wide; lateral margins parallel; posterior margin widely rounded. First valvula of ovipositor ( Fig. 2F View Fig ) with dorsal sculptured area areolate-strigate. Other characters as in generic description.

Remarks

Takiyaella anomala gen. et sp. nov. is the species that most differs from the other species of the genus, being the only one to have the forewing with a dark-brown macula in the fourth apical cell ( Fig. 1D View Fig ); male pygofer, in lateral view, not expanded apically, caudal margin without ventral lobe ( Fig. 1E View Fig ); connective Y-shaped ( Fig. 1H View Fig ); and aedeagus with shaft laterally compressed and not expanded apically ( Fig. 1J–K View Fig ).
