Amata macroflavifer sp. n.

Amata macroflavifer (paratype)

16-18mm, 27-29mm. The general facies is much as in the previous yellow species and in the two following, though the size is greater, comparable with that of teinopera Hampson. The hindwings are relatively large, rounded in the male, the basal yellow area with an excavate exterior margin. In the female the hindwings are narrower, the yellow less strongly excavate. The abdomen has broad rings basally and at two thirds, but there are two narrower rings distal to the latter. In the male genitalia both valves are elongate, tapering, robust, the right somewhat longer than the left: the basal costal processes are massive, reflexed subapically, slightly bulbous, subequal. The uncus is short, robust. The aedeagus vesica is slender, with a row of rather small cornuti; there is a small, coarsely scobinate process at the apex of the aedeagus.
