Description.
Male ( Fig. 3 View Figures 1–4 ): Antenna length 7.2 mm; forewing length 10.3 mm; body length 12.5 mm. Head: antenna black with blue sheen, dorsally and light brown with a few yellow scales ventrally; frons white; labial palpus yellow with black apically; vertex black; pericephalic scales yellow with a few yellow-orange scales. Thorax: patagia dark brown to black, with a small yellow spot laterally; tegula black with a yellow dorsal line, narrowly bordered with yellow scales; thorax laterally yellow with small black scales; mesothorax black with a few yellow scales anteriorly; metathorax yellow, with a few black scales; posteriorly metepimcron and metameron with brown and yellow hair-like scales. Legs: fore coxa yellow with golden sheen, with a broad dark brown to black stripe; fore femur externally dark brown, internally yellow; fore tibia yellow with golden sheen, with admixture of dark brown scales; fore tarsus yellow; mid coxa dark brown to black, with a few yellow scales; mid femur externally dark brown to black, internally yellow; mid tibia yellow, spurs yellow; mid tarsus exterior-dorsally dark brown to black, interior-ventrally entirely yellow; hind leg similar; hind tibia yellow, with a dark brown to black spot distally. Abdomen: dorsally dark brown to black with blue sheen; tergites each with a broad, broadened laterally, yellow stripe distally; abdominal tuft black, dorsal with yellow V shape spot, lateral margins with yellow-orange scales. Forewing: basally black; costal margin dark brown to black, with a narrow yellow stripe between vein Sc and R-stem; discal spot and veins within exterior transparent area dark brown to black; apical area brown with admixture of orange scales; discal spot broad; exterior transparent area large divided into four cells, level to M2 about 3.2 × as broad as discal spot and 0.8 × as broad as apical area; posterior transparent area reaching distal margin of discal spot; cilia brown. Hindwing: transparent; veins, discal spot black, small, cuneiform, reaching to vein M2; cilia dark brown, yellow anally.
Female ( Fig. 4 View Figures 1–4 ): Antenna length 8.3−8.7 mm (n = 2); forewing length 12.1−12.5 mm (n = 2); body length 13.8−14.1 mm (n = 2). Body and legs with more numerous yellow scales; anal tuft yellow-orange laterally. Color patterns otherwise as in male.
Male genitalia (Gen. Prep. JYL-301, NTNU, Fig. 6 View Figures 5, 6 ): Tegumen-uncus complex narrow; scopula androconialis well-developed, long, about as long as tegumen-uncus complex; crista gnathi medialis relatively long with sinusoid margin; crista gnathi lateralis shorter and narrower than crista gnathi medialis; valva trapeziform-oval, covered with apically bifurcate setae; ventral crista small, covered with triangular flat-topped setae; phallus thin, slightly shorter than valva; vesica with numerous small cornuti.
Female genitalia (Gen. Prep. JYL-300, NTNU, Fig. 8 View Figures 7, 8 ): Apophysis posterioris about as long as apophysis anterioris; ostium bursae opening somewhat anteriorly of 8th tergite; antrum narrow, long, about twice shorter than anterior apophysis, well-sclerotized; ductus seminalis just from anterior margin of antrum; ductus bursae membranous, narrow, slightly longer than antrum, gradually broadened towards corpus bursae; corpus bursae globose to ovoid, without signum.
Diagnosis.
Paranthrenella helvola sp. nov. is similar to P. similis Gorbunov & Arita, 2000 which was described from Vietnam. P. helvola may be distinguished from P. similis by forewing without a transparent area of a cell between veins R4 and R5, with a narrow yellow stripe between vein Sc and R-stem; abdominal tuft with yellow V shape spot of male. P. helvola possesses wing pattern similar to P. albipuncta Gorbunov & amp; Arita, 2000 from Vietnam. P. helvola can be distinguished by the coloration of the antenna black, with a large yellow spot in P. albipuncta .
Etymology.
The name of this new species is the feminine form of the Latin adjective helvolus, meaning yellowish, because of the overall yellow coloration of the body trunk and legs of the moth.
Biology.
Females lay eggs in the crack of bark ( Fig. 12 View Figures 9–12 ). The larva bores into the trunks of Cinnamomum camphora (L.) ( Lauraceae ) and feeds on callus tissue around the hole, which is covered with silk, debris, and frass. The adults have been observed taking nectar from flowers of Ampelopsis brevipedunculata (Maxim.) Traut. ( Vitaceae ) during day time.
Distribution.
Known only from Taiwan.
Remarks.
The male genitalia of P. helvola sp. nov. are similar to those of P. albipuncta Gorbunov & Arita, 2000, but the color of the antenna of these two species differs considerably.
