Abstract: Metathrinca Meyrick, 1908 Metathrinca Meyrick, 1908: 625. Type species: Ptochoryctis ancistrias Meyrick, 1906, by original designation. Diagnosis. The genus Metathrinca is diagnosed by the combinations of the following features: the head with spreading lateral tufts, the labial palpi curved upwards, the antennae bipectinate in male and filiform in female, and the forewings typically white with an outwardly arched subterminal line and sometimes also with a terminal line; R 3 absent, R 4 and R 5 stalked in the forewing, and M 3 and CuA 1 stalked in the hindwing (Fig. 1 a), and the abdominal tergites possessing a band of spines posteriorly (Fig. 1 b). The male genitalia are distinguished by the gnathos with dense protuberances, the developed saccular process usually bearing setae and a row or a cluster of spines, and the simple phallus rarely with a cornutus. The female genitalia are distinguished by the small subcircular or elongate ostium bursae, the ductus bursae mostly longer than the elliptical or ovoid corpus bursae, and the signum, if present, usually with a sclerotized transverse band or a ridge.
