Legs: fore coxa and femur black with blue sheen; fore tibia dorsally black with a few white-yellow scales basally; fore tarsus ventrally white with a few dark gray scales, dorsally black with a some pale yellow spot on each tarsomere basally; hind tibia black, internally and at base of both pairs of spurs pale yellow; hind tarsus ventrally white with a some pale yellow spot on each tarsomere basally, dorsally black with blue-violet sheen; spurs white. Abdomen: black with blue-bronzed sheen; tergite 2 with a few pale yellow scales medially; tergite 4 with a narrow yellow stripe distally; sterna black, others densely mixed with white scales; anal tuft dorsally dark brown to black with blue sheen, with a narrow white scales laterally, ventrally black. Forewing: basally black; costal margin dark brown to black; discal spot and veins within exterior transparent area dark brown to black; apical area dark brown, with bronzed-purple sheen; discal spot broad, slightly broadened medially; exterior transparent area large divided into five cells, level to M2 about 2X as broad as discal spot and 1.5X as broad as apical area; posterior transparent area reaching distal margin of anterior transparent area; fringe dark brown, with purple sheen. Hindwing: transparent; veins, discal spot and outer margin dark brown to black with bronzed-purple sheen; discal spot small, cuneiform, reaching to vein M2; outer margin dark brown to black, about 1− 2 X as broad as fringe; attenuate toward tornus; fringe black with bronzy sheen. Female (Fig. 9). Antennae length 5.1−5.8mm (n=8); forewing length 7.9−8.3 mm (n=8); body length 8.0− 8.9 mm (n=8). External morphology and wing pattern identical to those male.

Genitalia. Male (Gen. Prep. JYL-17, NTNU, Fig. 20). Tegumen-uncus complex broad; scopula androconialis well-developed, long, about 3/ 4X length of tegumen-uncus complex; crista gnathi lateralis large, semi-oval; crista gnathi medialis long, narrow, somewhat broader than crista gnathi lateralis, with distal margin divided into two narrow cristae; valva elongated, trapeziform-oval; crista sacculi oblique, pocket-shaped, gradually lowered posteriorly, covered with dense, strong, bifurcate setae anteriorly at upper margin; saccus slightly broadened and rounded basally, about twice as short as vinculum; phallus relatively narrow, about 3/ 5X as short as valva; vesica short with numerous, irregular, minute cornuti. Female (Gen. Prep. JYL-18, NTNU, Fig. 26). Papillae anales relatively long and broad, covered with short setae; 8th tergite narrow with short setae distally; posterior apophysis about 1.2X longer than anterior apophysis; ostium bursae narrow; antrum slightly funnelshaped, well-sclerotized; ductus seminalis just at anterior margin of antrum; ductus bursae membranous, narrow, long, about 1.5X as long as anterior apophysis; corpus bursae globose, membranous, without signum.

Diagnosis. Kantipuria glandicola sp. nov. is similar to and appears to be closely related to K. lyu Gorbunov & Arita 1999 described from Nepal. K. glandicola. differs from K. lyu by the smaller size (antenna 6.3 mm, forewing 8.6 mm versus body length 10.7 mm in K. lyu) and coloration of the female abdomen (black with blue-bronzed sheen; tergite 2 with a few pale yellow scales medially; tergite 4 with a narrow yellow stripe distally; in K. lyu a broad brick-red stripe present distally from tergites 3−6).

Etymology. A noun of Latin origin, glandi = acorn, plus an adjective of Latin origin, cola = life.

Biology. The larva bores into acorns of Castanopsis and Lithocarpus (Fagaceae). Its feeds on kernel around the entrance hole, which is covered with silk, debris and frass.

Distribution. Known only from Taiwan.

Remarks. The genitalia of both sexes of Kantipuria glandicola sp. nov. are similar to those of K. lyu Gorbunov & Arita 1999, though markings of wings and body and body size of these two species differ considerably.
