Nokona bractea Kallies & Arita sp. nov.

( Figs 4 , 30 )

Material examined. Holotype. ♂, Guangxi, Guilin, Maoershan, 500–1500 m, 6–10.VIII.2007 ( Fig. 4 , Gen. Prep. AK759) ( SCAU). Paratype. 1♂, same data as holotype ( NSMT).

Description. Male ( Fig. 4 ). Wingspan 42 mm; forewing length 18 mm; body length 25 mm. A very large and distinctive species; most body parts black with a bluish sheen; patagia bright yellow. Head: labial palps yellow ventrally; pericephalic scales yellow ventrally. Thorax: patagia yellow; metathorax with few white scales subdorsally. Forewing: black with a bluish sheen; with a small semitransparent area at the base between cubital stem and anal margin. Abdomen: anal tuft triangular, well developed, with a few yellow scales ventrally.

Genitalia. Male (Gen. Prep. AK759, Fig. 30 ). Valva appearing rectangular, dorsal area densely covered with hand-shaped setae, ventral part with simple setae, with only few setae in the middle field; gnathos (a) with simple projections; uncus relatively straight; phallus, relatively short and thick, tapering towards the tip, with a distinct tooth subapically.

Diagnosis. This species is distinct from most known species of the genus Nokona . It is similar to Nokona stroehlei Fischer, 2002 , which was described from the Malay Peninsula. It differs by the markings on the hindwing (with narrow discal spot, narrow outer margin and fine veins in N. bractea ; with broad discal spot, broad outer margin and broadly scaled veins in N. stroehlei ). N. bractea also shows some similarity to N. noblei . The latter differs by its transparent hindwings (lacking the smoky appearance of N. bractea ), its hind legs that are marked with yellow, its partly yellow tegulae, and its black patagia.
