Chen, Liusheng & Wang, Min, 2006, Notes on the genus Leucolopha (Insecta, Lepidoptera, Notodontidae) with description of a new species from China, Zootaxa 1327, pp. 63-68 : 65-66

Leucolopha sinica , sp. nov.

( Figs. 2–5 )

Diagnosis. The new species is similar to L. undulifera and L. singulus in wing pattern but can be distinguished by the characters listed in the key. It is easily separated from its presumably closest relative, Leucolopha undulifera , by the stouter uncus branch and the gnothos not swollen.

Description. Head: Dark brown. Antenna filiform; palpus ferruginous, porrect and reaching just beyond the frontal tuft, tip cuspidal. Compound eyes naked and rounded, black.

Thorax: Uniformly dark brown. Tibia of hindleg fringed with long hair. Forewing length 19 mm in male, 25 mm in female. Forewing upperside ferruginous brown, with a longitudinal sinuous dark brown subcostal fascia from the base to apex; a black basal fascia and dark brown antemedian, postmedian, submarginal fasciae, and the distal cell spot black. Basal fascia curved outwardly to subcostal fascia then jags basally a millimeter or so, whence it continues to and meets the costa perpendicularly. Antimedian fascia slightly concave dorsally of the subcostal fascia then straight to the costa, postmedian and submarginal fasciae straight to the subcostal fascia then angled inwardly to costa. Both of the antimedian and postmedian fasciae margined outwardly with white, while submarginal fascia margined inwardly with white; cilia rusty brown. Hindwing dull light reddishbrown, antemedian and postmedian fasciae distinct.

Abdomen: Yellow brown dorsally and light yellow brown ventrally. Male genitalia ( Fig. 4) with uncus bearing two long digitiform branches, each branch with a basal bulge; tegumen band­shaped; saccus indistinct; gnathos boot­shaped; valva with costa gradually convex basally and concaved to cucullus, cucullus broad and rounded, stout; aedeagus slender, slightly longer than valva; cornutus absent. Female genitalia ( Fig. 5 ) with posterior apophysis about 2/3 as long as anterior apophysis, ductus bursae dilated at base, membranous; corpus bursae small and rounded, membranous, without signum.

Holotype: Male, Gonggashan National Nature Reserve, Sichuan Province, China, 3100 m, 30­VII­2003, leg. Min Wang. Paratypes: 1 male, same data as holotype; 2 males, 3­V­2004; 2 females, 20­VII­2004; 3 males, 11­X­2004, leg. Q. Y. Liang, other data same as holotype. 1 male, Tianpingshan, Badagongshan National Nature Reserve, Sangzhi County, Hunan Province, China, 1400m, 28­IV­2006, leg. Liusheng Chen.

Holotype and paratypes deposited in the Insect Collections of the Department of Entomology, South China Agricultural University, Guangzhou, P. R. China.

Distribution: China (Sichuan and Hunan Provinces).

Etymology: The species is named after the country of its type locality.
