Takanea Nagano

Type species: miyakei Wileman.

This genus has a general appearance suggesting relationship with Arguda and lacks humeral veins of the type seen in
Fig. 3, thus resembling Arguda and Radhica and differing from Syrastrena. The humeral zone is strongly expanded at the base but then narrows rapidly again to converge with vein Sc.

The wing margins are slightly scalloped, the hindwing more strongly excavate in the spaces between Sc, Rs and M1. The forewing patterning consists of post- and antemedial fasciae flanking a discal spot, and an irregular submarginal fascia. There is a pale medial band at the hindwing costa in all species, but in diehli it extends right across the wing.

The male antennae are broadly bipectinate over the whole length, those of the female much more narrowly so.

The male genitalia have the valve divided, the cubile triangular, the apex of the triangle produced, and a double process at the aedeagus apex.

The genus consists of two northern Oriental species: the type from Japan and China; excisa Wileman from Taiwan. The single Sundanian species is thus well separated from the rest of the generic range.
