Male pygofer ( Fig. 1E) rectangular, not expanded apically. Connective ( Fig. 1H) Y-shaped. Aedeagus ( Fig. 1J–K) 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.    Material examined    Holotype BRAZIL• ♂; Rio de Janeiro, Cachoeiras de Macacu, REGUA [Reserva Ecológica de Guapiaçu], ponto 4, casa de pesquisa, trilha verde; 22°24′28.30″ S, 42°44′16.10″ W; alt.  296 m;  25 May 2019; R.L.C.

Subgenital plate, in lateral view ( Fig. 1F), 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), 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) Y-shaped, total length about 3/5 length of style; stem approximately as long as arms. Style ( Fig. 1H– I) with dorsal margin of apodeme broadly rounded, ventral margin acutely produced anteroventrally; apophysis elongated, robust. Aedeagus ( Fig. 1J–K) 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) with sternite X long and tubular, without basiventral process. FEMALE TERMINALIA. Sternite VII ( Fig. 2A–C) 1.2 × as long as wide; lateral margins parallel; posterior margin widely rounded. First valvula of ovipositor ( Fig. 2F) 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); male pygofer, in lateral view, not expanded apically, caudal margin without ventral lobe ( Fig. 1E); connective Y-shaped ( Fig. 1H); and aedeagus with shaft laterally compressed and not expanded apically ( Fig. 1J–K). 3387265310 2019-05-25 coleta visual alta diurna DZRJ R.
