Wang, Houshuai, Wang, Min & Fan, Xiaoling, 2011, Notes on the tribe Nygmiini (Lepidoptera: Erebidae: Lymantriinae) from Nanling National Nature Reserve, with description of a new species, Zootaxa 2887, pp. 57-68 : 63-64

Euproctis montis ( Leech, 1890)

( Figs. 17–18 , 36 , 48 )

Artaxa monits Leech, 1890: 111 .

Nygmia montis: Swinhoe, 1922: 482 .

Euproctis montis: Strand, 1910: 137 ; Chao, 2003: 409.

Diagnosis. Forewing length 14–20 mm. Forewing yellow, with two pale yellow median lines and a darker band from lower angle of cell oblique to middle of dorsum; hindwing slightly paler than the forewing. Male genitalia ( Fig. 36 ): Uncus broad, with constricted sides; valva short and wide; costa strongly sclerotized, slightly protruded apically; saccus relatively large; aedeagus straight, vesica with irregular fields of spines. Female genitalia ( Fig. 48 ): Apophysis anterioris longer than apophysis posterioris; sterigma inflated, sclerotized; ductus long, membranous; bursa with a transverse signum.

Material examined. 23, 3Ƥ, Nanling National Nature Reserve, Guangdong, 7.VIII.2009.

Distribution. China (Gansu, Jiangsu, Shanxi, Hubei, Zhejiang, Sichuan, Xizang, Jiangxi, Fujian, Hunan, Guangdong, Guangxi, Yunnan, Hainan).

Remarks. The species is allied to E. collenettei Chao, 1994 , but the latter is distinct in forewing with scattered black scales near middle of dorsum rather than a dark oblique band. Female genitalia are illustrated here for the first time.
