Promalactis mooatana Kim

sp. nov.

Promalactis mooatana Kim  , sp. nov.


This species is close to Promalactis superimposita Wang, Du & Li, 2013  , in the wing pattern, but it can be easily distinguished by the tougue-shaped gnathos and the aedeagus with blunt sub-apex and the longer cornutus in the male genitalia.

Antenna with scape white entirely, as long as diameter of eye; flagellum white from base to one-quarter, white and dark brown alternately from one-quarter to apex dorsally. Labial palpus with yellowish brown of second segment and dark brown of third segment; third segment shorter than second segment. Thorax: Thorax and tegula yellowish dark brown. Wingspan 10.0– 10.5 mm. Fore wing ground colour yellowish brown; two bands and one costal patch; all these white markings edged with fuscous scales: subbasal band very oblique, from base of costal margin towards one-sixth of posterior margin, not reaching posterior margin; antemedial band arched, from one-quarter of costal margin to one-third of posterior margin; costal patch at two-thirds, semi-circular; apical patch not developed; fuscous suffusions before tornus and near apex; fringes brownish yellow two-thirds of posterior margin to apex, darker near tornus. Hind wing ground colour and fringes greyish brown. Male genitalia ( Figure 4g, 4 ga–c). Uncus triangular, wide at base, gradually narrowed toward apex, longer than gnathos. Gnathos tougue-shaped, shorter than uncus, gradually wider toward apex; apex round. Valva symmetrical, rectangular, shorter than uncus plus tegumen, split apex; cucullus club-shaped, setose caudally, as long as sacculus; sacculus middle finger-shaped, thicker than cucullus, setose entirely.
