8-9mm. A male from
Palawan in the Zoological Museum, University of Copenhagen, was taken originally
to represent the type species, matching the females from Luzon in facies, but
subsequently Dr K. Yazaki sent the author photographs of a male with similar
facies from Luzon, and of its genitalia. The most distal fawn element of the
postmedial banding is much narrower than in neophantes. The pale zone
basal to this band on the forewing dorsum is much longer, semicircular, filling
the space between the band and the base of the wing. The fawn costal and distal
margins to the wings are narrower, less clearly defined. The male genitalia are
twice as large as those of neophantes, but the lyre-like uncus is
relatively more slender. The gnathus is apically bilobed rather than bifid. The
valves taper more to a point, with the spinose apex of the costa coincident with
the valve apex itself (this occurs in the Luzon male but the costal apex is well
short of the valve apex in the Palawan male). The saccus of the Luzon male is
squarish rather than triangular..
