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 ). Forewing ( Fig. 3D ) 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 ), 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 ), subtriangular, 3.3 × as long as maximum height, slightly expanded medially; in ventral view ( Fig. 3G ), 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 ) V-shaped, total length approximately ⅔ length of style; stem very short. Style ( Fig. 3H–I ) with apophysis very elongated and slender; ventral margin distinctly rounded near median third. Aedeagus ( Fig. 3J–L ) 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 ) with sternite X long and tubular, with triangular basiventral process with denticles. FEMALE TERMINALIA. Sternite VII ( Fig. 4A–C ) as long as wide; posterior margin slightly excavated medially. First valvula of ovipositor ( Fig. 4F ) 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 , 10D ) and the shape of the aedeagal shaft expanded apically, with lateral margins rounded, bearing several small spiniform projections ( Figs 3J–L , 10I–J ). 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 ), 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 ).
