( Figs. 21–22 , 38 , 50 )

Euproctis yunnanpina Chao, 1984: 454 ; 2003: 365.

Diagnosis. Forewing length 14–20 mm. Forewing covered with darker scales from base to submarginal area, crossed by two yellowish white transverse lines medially, apically with two black spots.Male genitalia ( Fig. 38 ): Uncus rather triangular; valva broad at base, cucullus sclerotized, with two small processes; saccus long; aedeagus bent near apex; apex slightly concave medially, with an acute process at dorsal margin. Female genitalia ( Fig. 50 ): The eighth segment relatively narrow; papilla analis broad; apophysis anterioris longer than apophysis posterioris; ductus sclerotized basally; bursa large, signum with a transverse flange.

Material examined. 13, Nanling National Nature Reserve, Guangdong, 1.VIII.2006. 13, same locality, 20.IV.2009; 13, 2Ƥ, same locality, 7.VIII.2009.

Distribution. China (Guangdong, Guangxi, Yunnan).

Remarks: The female of this species is superficially similar to Arna pseudoconspersa (Strand) , but distinguished from the latter by a transverse flange arising from a sclerotised signum within the bursa. Female genitalia are illustrated here for the first time. Detailed biological information is given by Chao (2003).
