Scoliokona spissa Kallies & Arita

sp. nov.

Scoliokona spissa Kallies & Arita   sp. nov.

( Figs 25, 26 View FIGURES 21 – 28 , 38 View FIGURES 38 – 39 )

Material examined. Holotype. 1 ♂, Guangxi, Guilin, Maoershan, 500–1500 m, 6.– 10.VIII. 2007 ( SCAU). Paratypes. 1 ♂, same data as holotype ( NSMT); 8 ♂, same locality, 730 m, 15.– 19.VIII. 2009 ( Fig. 25 View FIGURES 21 – 28 , NSMT, CAK, Gen. Prep. AK 718); 2 ♂, 1 ♀, Prov. Guandong, Shaoguang, Nanling, 600 m, 2–6.VII. 2012 ( Fig. 26 View FIGURES 21 – 28 , CAK).

Description. Male ( Fig. 25 View FIGURES 21 – 28 ). Wingspan 31.5 mm; forewing length 13.5 mm; body length 16.5 mm. Most body parts black, with a purplish lustre. Head: labial palps with apical segment long and smooth, otherwise rough scaled; in distal third white ventrally; pericephalic scales white and black mixed dorsally. Thorax: fore coxa crème medially; mid and hind coxae crème with some black scales; hind tibia with crème patch at first pair of spurs. Forewing: opaque, black with a purple sheen; with small remnant PTA at the base; ventrally similar with crème scales at the base. Hindwing: largely transparent, appearing somewhat smoky; with costa yellowish at the base. Abdomen: tergite 2 usually with yellow scales along distal edge; tergite 3 with few yellow scales a long distal edge laterally; sternite 3 dirty crème to yellow; anal tuft very small, with few white scales laterally. Female ( Fig. 26 View FIGURES 21 – 28 ).

Similar to male, but somewhat larger (wingspan 38 mm), antennae simple, labial palps slimmer and shorter scaled, tergites 2 and 3 with narrow yellow border laterally; sternite 4 almost completely dirty white.

Genitalia. Male (Gen. prep. AK 718, Fig. 38 View FIGURES 38 – 39 ). Valva relatively short and broad, covered in setae, only a narrow area medially and most basal devoid of setae; setae with downwards angled hands with each 6–7 finger like projections; gnathos with relatively long and strong ventral extensions; uncus apical very strong; phallus with two apical tips, each ending in a small tooth-like projection; base of vesica with additional small tooth near base.

Variability. The specimens show little variation in color or markings; 27 –31.5 mm wingspan.

Diagnosis. This species shows superficial similarities to Scoliokona tetrapora   (Diakonoff, [1968]) and Scoliokona heptapora Kallies & Arita, 1998   , both from the Philippines. Both of these species, however, differ from S. spissa   sp. nov. by their larger size, their reduced transparent areas of the hindwings, and their long and slender bodies. Furthermore, the male genitalia of both of these species conform to the typical Scoliokona   morphology (similar to S. shimentai   sp. nov.). Therefore, S. spissa   sp. nov. cannot be confused with any of its congeners or species of the related genus Nokona   . In particular the morphology of the genitalia is unique.

Biology. Males were attracted to pheromone lures; the female was collected on flowers of Cissus repens Lam   ( Vitaceae   ).

Remark. This species is unusual and may occupy an isolated position within the genus. In particular the morphology of the uncus, gnathos and phallus tip are unusual and not known from any other representative of Scoliokona   or related genera.
