Type species: Mckenziana maighreadae sp. n., by present designation.

Description. Male ( Figs 1–4, 6–20 ). Flagellum covered with brown scales or speckled, rami brown. Head, thorax and abdomen brown or cream-colored. Forewing. Forewing length: 24–30 mm. Elongated, apex blunt, external margin smooth. Background color brown or speckled. Pattern consists of white medial dot, pair of pale postmedial lines, dark brown and cream-colored wavy external line. Fringe brown or speckled. Hindwing. Somewhat triangular or oval, indentation on veins may be pronounced. Background color and fringe brown or speckled brown. Genitalia ( Figs 35–44 ). Tegumen a narrow band, medially widened; laterally bears a pair of socii. Socii papilla-shaped, covered with setae. Vinculum ventrally elongated, distally bears cubile with small proximal apodeme. Cubile divided medially into a pair of somewhat oval processes with one medial spur and some indentations along the inner margin. Cucullus elongated, finger shaped with blunt apex, basally covered with setae. Sacculus about half the length of cucullus, basally covered with setae. Juxta knob-like, fused with aedeagus. Aedeagus straight with very short basal apodemes, ventromedially bears claw-like extension or spur with pointed apex. Vesica spherical may be covered with minute dents. The eight sternite somewhat oval, medially membranous, basally more sclerotized with barely pronounced apodemes. The eight tergite elongated, somewhat pentagonal, medially membranous, basally has a pair of lateral apodemes. Female ( Figs 5 , 21–24 ). Flagellum speckled cream-colored and brown; rami brown, shorter than of male. Head, thorax and abdomen speckled cream-colored and brown; abdomen also may be cream-colored. Forewing. Forewing length: 35–51 mm. Oval, elongated, apex blunt, external margin smooth. Background color speckled cream-colored and brown. Pattern consists of white discal dot, pair of pale medial lines and dark brown and orangish wavy external line. Fringe speckled cream-colored and brown. Hindwing. Oval, external margin wavy with peaks on veins. Background color cream-colored and brown, costal and anal angles darker. Fringe speckled cream-colored and brown. Genitalia ( Figs 49–50 ). Papillae anales oval, densely covered with setae. Posterior and anterior apophyses about the same length. Antevaginal plate a narrow band with medial spherical membranous extension forming antrum. Postvaginal plate somewhat hexagonal with mediocaudal concavity around spherical extension of antevaginal plate. Ostium amorphous. Ductus bursae not pronounced. Corpus bursae elongated, bears no singum.
