Zebraodes lucidalis Heppner & Bae , new species

( Figs. 1–18)

Type locality. Vietnam (Cuc Phuong National Park ( Mac Lake ), Ninh Binh Prov.).

Diagnosis. This species is distinctive by its mottled, sometimes silvery forewing markings which are mostly solid along the costal margin and vertically aligned on the remainder of the forewing. The forewings and dark hindwings overall have a slight bluish iridescence in some individuals.

Description. Male ( Figs. 1–2). Head ( Figs. 4–6): Vertex dark tan, with gray between antennal bases; frons gray, with dark gray along eye margins; labial palpus pale gray, with tan basally and mesally; antenna gray-brown. Thorax: Dark gray, with posterior spot bronze-gold; tegulae tan-gray; venter cream-white; legs gray mixed with some tan; tibiae and tarsi banded with dark brown, hindlegs mostly lustrous tan-gray. Wing expanse 24.0 mm in male (n = 9). Forewing ( Figs. 1–2) dark brown to black-brown, more brownish towards dorsal margin, with overall slight bluish iridescence and violet iridescence on silvery markings, with silvery-gray markings as a solid band along costal margin about 1/4 of wing-width wide and mottled with lighter spots, remainder of forewing with numerous vertical silver irregular striae from costal band to dorsal margin, with intervening background black coloration relatively evenly spaced until the apical 1/5 where dark space is wider, and along termen; a very thin silver margin along termen; fringe dark gray; venter dark gray. Hindwing uniformly dark brown to gray, with slight bluish iridescence; venter dark gray. Abdomen: Dark gray, with bronze shine to slightly bluish towards posterior; venter gray, with light tan on posterior half of each sternite; genital tuft tan. Male genitalia (Figs. 10–11, 16–17) as described for genus.

Female ( Figs. 3, 7–9). Head and Thorax: Same as male, but wing expanse 27.8 mm (n = 1). Abdomen: Female genitalia (Figs. 12–13, 18) as described for genus.

Specimens examined. Holotype ♂ ( Fig. 2): Vietnam: Cuc Phuong National Park, Mac Lake , 155 m, Ninh Binh Prov., 9–13 April 2012, J.B. Heppner (gen. slide JBH 3495 ♂) ( MGCL) . Paratypes (8♂ 1♀): Vietnam: Same data as holotype (4♂, 1♀) (gen. slide JBH 3159 ♀) ( MGCL) ; 10 Aug 2005 (1♂), Y.S. Bae, J.H. Bae, & N.V. Pham (INUC). Ninh Binh Prov.: Doi Vau Village, Cuc Phuong , 135 m, 10–16 Sep 2013 (1♂), J.B. Heppner ( MGCL) . Hatay-Hanoi Prov. : Ba Vi Natl. Pk., 455 m, 19–23 Jul 2010 (1♂), J.B. Heppner & Y.S. Bae (gen. slide JBH 3101 ♂) ( MGCL) ; Ba Vi Natl. Pk., 800 m, 31 Jul 2010 (1♂), Y.S. Bae & X.V. Le (INUC).

Etymology. The species name refers to the lustrous shine of the forewings.

Biology. Unknown.

Distribution. Recorded only from northern Vietnam.

Discussion. Adults were collected mostly at Cuc Phuong National Park where two forms were taken: a lighter, more silvery form ( Fig. 1) and the more common darker form ( Figs. 2–3). Specimens of the dark form include both males and females, but the light form is thus far known only in one male; thus the dark form is likely the typical form of the species. The dark form has a slight violet iridescence on the silvery markings in addition to the overall bluish iridescence, whereas in the light form the violet shine is less evident. The male genitalia of the light form are shown in Fig. 16; those of the dark form are shown in Fig. 17. Because no significant differences could be detected between the genitalia of the two forms, we considered them conspecific. Although not clearly visible in Fig. 16, the male genitalia of both forms have a spatulate apex of the gnathos.
