Diagnosis.

Adult (Fig. 8) wingspan 32.0-41.0 mm. This species is characterized by the uncus inverted trapezoidal and the valva with a triangular process at basal 1/3 of the ventral margin (Fig. 13). It is similar to L. solivaga sp. n. in the forewing pattern and to L. viridis sp. n. in the male genitalia. The differences between the three species are stated above under the treatments of the latter two species.

Variation.

Specimens collected from Guizhou and Guangxi are darker than those from other localities.

Host plants.

Anacardiaceae : Pistacia chinensis Bunge, Rhus chinensis Mill., R. sylvestris Sieb. et Zucc., R. verniciflua Stokes; Juglandaceae : Juglans mandshurica Maxim., J. mandshurica var. sieboldiana Makino, J. sinensis (C. DC.) Dode., Pterocarya stenoptera C. DC.; Simaroubaceae : Ailanthus altissima (Mill.) Swingle ( Bae and Paek 2006).

Distribution.

China (Fujian, Guangdong, Guangxi, Hainan, Hebei, Henan, Hongkong, Hubei, Hunan, Jiangxi, Liaoning, Shaanxi, Sichuan, Tianjin, Tibet, Yunnan, Zhejiang), Japan, India, Sri Lanka ( Wang et al. 2003).

Remarks.

Walker (1866) described this species based upon the external characters, and our specimens match the wing pattern of his description. Locastra muscosalis resembles L. crassipennis in the male genitalia, as given by Janse (1931), but can be distinguished from the latter by its short and sub-globose scape extension distinct from that of L. crassipennis which is large, very broad at the base, and sickle-shaped in the distal 2/3.
