Spulerina parthenocissi Kumata & Kuroko, 1988 ( Figs 2A , 4A , 5D )

Spulerina parthenocissi Kumata & Kuroko, 1988 , In: Kumata et al., 1988b: 86. TL: Japan. TD: HUJ.

Diagnosis. This species is most similar to S. castaneae Kumata & Kuroko, 1988 in the forewing patterns, but can be separated from the latter by the fan shaped comb about 1/3 width of valva in the male genitalia, the signum with median projection minute and only forming an angulated point in the female genitalia. While in S. castaneae , the fan shaped comb is about 2/3 width of the valva, the median projection of the signum is long and somewhat ensiform ( Kumata et al., 1988b).

Description. Adult. Wingspan 6.4−7.5 mm. Head smooth and raised, bright white. Labial palpus white, with end of 2nd and 3rd segments brown. Scape white with brown scales downward; flagellum light brown or yellowish white with metallic luster, gradually darken towards tip. Thorax and tegula bright white. Legs white, with black spots or rings; fore leg with tibia having black spot; mid and hind leg with tibia having black spot, black ring of distal part of each segment of tarsus. Forewing brown, with five white fasciae inlaid with black scales across forewing: first fascia at basal 1/7, with costal part slightly bend outward, inner part scattered black scales; second about 1/5 of forewing in width at base 2/7, with outer edge slightly outward inclined; third in middle of wing, parallel-sided, slightly narrower than second; fourth one at distal 1/3 and about 1/2 width of third, sometimes broken; fifth wider than fourth, with an irregular black transverse line go across; area beyond fifth fascia black; cilia around apex black, grayish yellow on dorsum. Hindwing and cilia gray.

Male genitalia. Tegumen nearly parallel-sided on basal half, narrowed on distal half. Tuba analis with a linear sclerotization in middle. Valva longer than tegumen, curved upward, wide basally, with distal 1/3 tapering, rounded apically, inner side densely covered with fine short setae, fan-shaped comb with 5–6 long teeth in middle near costa at distal 1/3, about 1/3 width of valva. Phallus thick, same length as valva, with densely covered with small spines distally; vesica having a conical sclerotization, ductus ejaculatorius J-shaped, slightly shorter than valva. Eighth abdominal segment about as long as 7th, dorsal apodeme about 3/4 as long as 8th abdominal segment.

Female genitalia. Apophysis anteriores as long as posteriores. Ostium bursae small. Antrum weakly sclerotized, annular, with a narrow crack ventrally. Ductus bursae lined with small spines, slightly expanded and with longitudinal wrinkles at basal 1/3. Corpus bursae membranous, oval; signum strongly sclerotized, long and slender, with median process an acute point, anterior part strongly curved, posterior part shorter.
