Hu, Yanqing, Wang, Min & Han, Huilin, 2015, Two new species and five new records of Nola Leach, [1815] (Lepidoptera, Nolidae, Nolinae) from China, Zootaxa 3920 (3), pp. 483-487 : 484-485

Nola puera Hu, Wang & Han sp. nov.

( Figs 6–10 )

Materials examined. Holotype. Male, Simao, Puer, Yunnan, 15–19.VII.2009, Huilin Han & Mujie Qi ( NEFU). Paratypes. 2 males, the same data as the holotype ( NEFU); 1 female, Puer, Yunnan, 14.VI.2007, Huilin Han ( NEFU).

Diagnosis. Nola puera is extremely similar to N. erythrostigmata Hampson, 1894 on external feature, but there are some slight differences: N. puera has the somewhat wider forewing, the broader antemedial line, a right-angle bending in middle of postmedial line and at posterior of subterminal line, while N. erythrostigmata has a black and big dot at front of antemedial line, a obtuse angle at counterpart of postmedial and subterminal lines. In male genitalia, the main differences are as follows: N. puera has a relatively short and broad valva, a small, triangular and apically pointed harpe and the vesica without cornuti ( Figs 7 & 8 ), while N. erythrostigmata has a narrower and longer valva, a long and apically round harpe and the vesica with a long cornutus. In female genitalia, N. puera has a narrower and shorter ductus bursae with anterior part broaden, while N. erythrostigmata has a longer and broader ductus bursae with posterior part broaden.

Description. Adult ( Figs 6 & 9 ). Wingspan 12–15 mm. Head and thorax white; antenna brown, bipectinate in male; labial palpi grayish white. Collar grayish white with brown dots. Abdomen grayish yellow in male and grayish white in female. Forewing ground color white; basal line undistinguished, but with a brown patch at wing base; antemedial line blackish brown, wide, arc-shaped; medial line being absent; postmedial line brown, double lines, inner line faint, excurved to R5, straight to Cu1, then right-angle bending to inner margin, with a brown patch at front; subterminal line brown and waved; terminal line brown with brown dots at inside; cilia gray with brown. Hind wing ground color gray; veins highlighted; discal spot pale brown. Male genitalia ( Figs 7 & 8 ): Uncus degenerated; tegumen slightly broad; dorsal valva broader and longer than ventral valva, slightly sclerotized at costal margin; ventral valva narrow and short with a small spine at top, sclerotized at ventral margin; harpe small triangle, pointed apically; juxta tongue-shaped; saccus small and funnelshaped. Aedeagus very short; vesica without cornuti. Female genitalia ( Fig 10 ): Papillae anales medium-long; apophyses posteriores and apophyses anteriores well developed; ostium fillister-shaped; ductus bursae thin, wide at anterior part, membranous, as long as corpus bursae; corpus bursae large, elliptical-ovoid, membranous, without signa.

Distribution. China (Yunnan).

Etymology. The specific name is derived from the locality of holotype, Puer.
