Abstract
The six species of the genus Andraca Walker hitherto known from China are reviewed, and a new species, Andraca gongshanensis, sp. n., described from Yunnan Province, China. Adults and male genitalia of all examined species are illustrated, together with a distributional map. A key to all seven Chinese Andraca species is provided. The types of the new species are deposited in SCAU (South China Agricultural University, Guangzhou, China) and HUNAU (Hunan Agricultural University, Changsha, China).
Highlights
The genus Andraca was established by Walker (1865) with Andraca bipunctata Walker 1865 as its type-species, a species well known as one of the most serious pests of tea plants (Chu and Wang 1996)
It was placed in family Bombycidae for over 150 years, but was recently transferred to family Endromidae based on the molecular study of Zwick et al (2011)
Chu and Wang (1993) recorded three Andraca species from China: A. bipunctata is widely distributed in central and southern China, A. henosa Chu & Wang, 1993 was listed from Yunnan, and A. hedra Chu & Wang, 1993 from Hainan and Fujian; in this paper, they included Andraca gracilis Butler 1885, which is currently placed in the genus Pseudandraca Miyata, 1970
Summary
The genus Andraca was established by Walker (1865) with Andraca bipunctata Walker 1865 as its type-species, a species well known as one of the most serious pests of tea plants (Chu and Wang 1996). (Type species: Andraca bipunctata Walker, 1865, List Specimens lepid. These four species form the bipunctata group, and share the following characteristics: 1) male hindtibia with one pair of spurs; 2) two dorsally-directed projections present on subapical part of valva; 3) external surface of aedeagus partially covered with hair-like spines; 4) a cluster of strong spinose cornuti on vesica.
