Figs. 4, 9
Diagnosis. Cameraria jiulianshanica is close to C. trizosterata Kumata regarding the shape of valva, tegumen and phallus, and the vesica lacking of cornutus, but can be distinguished as follows: branches of vinculum of C. jiulianshanica are pointed at apex, slenderer than those of C. trizosterata; in C. trizosterata, branches of vinculum are somewhat knobbed apically (Kumata 1993); phallus of C. jiulianshanica has no processes on the outer surface, vesica is sclerotized on distal part and pointed apically, while phallus of C. trizosterata has a minute barb at apex, and its vesica is membraneous (Kumata 1993); in addition, the second fascia of forewing of C. jiulianshanica and the third of C. trizosterata is interrupted (Kumata 1993).
Description. Adult (Fig. 4). Wingspan 7.0 mm. Head whitish, with tuft ochreous-white. Antenna whitish ventrally, fuscous dorsally, flagellum whitish dorsally at the base of each segment. Labial palpus whitish above, fuscous below. Thorax and tegula ochreous-yellow. Forewing grey-brownish, with a black spot close to the base above wing fold; three whitish fasciae present, delineated with black on outer side, arranged in parallel, oblique outwards from dorsum to costa; first fascia at basal 1/4 of dorsum, second one in middle, interrupted by ground colour near costa, the costal part formed as rounded spot surrounded with black, third fascia at tornus; fringe grey-brownish, on termen with a black median line. Hindwing and its fringe dark grey. Foreleg with coxa, femur and tibia black below, femur whitish above, tibia ochreous yellow dorsally except apex black; fore tarsus whitish, with three black rings. Midleg whitish; tibia with three black oblique streaks on outer surface; tarsus with four black rings. Hindleg with coxa and femur ocherous-white, tibia dark grey on outer side, ochreous-yellow on inner side, with long hairs above; tibia whitish, with four black rings.
Male genitalia (Fig. 9). Tegumen ca. 550 Μm long; bottle-shaped, distal 1/5 narrowed and bottleneck-like; bifurcate apically, each branch with a seta about 125 Μm in length. Valva bar-shaped, about 500 Μm long, tapering distally, apex with two tooth-like processes; inner surface densely covered with soft, long setae; sclerotized ridge placed at the base of valva, with a row of spine-like setae. Anellus cone-like, gradually widened towards anterior end. Vinculum with two branches anteriorly, each branch about 420 Μm long. Length of phallus about 800 Μm, gradually swollen about from the middle to the base; vesica without cornutus, apex sclerotized, spin-like. Flap-like eighth sternite about 300 Μm long, posterior margin concave, V-shaped.
