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).
Taxonomy, Lepidoptera, Endromidae, Andraca , new species, China
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). Kishida (1993) reported Andraca theae and Andraca olivacea from Taiwan. Chu and Wang (1993) recorded three Andraca species from China: Andraca bipunctata is widely distributed in central and southern China, Andraca henosa Chu & Wang, 1993 was listed from Yunnan, and Andraca hedra Chu & Wang, 1993 from Hainan and Fujian; in this paper, they also included Andraca gracilis Butler 1885, which is currently placed in the genus Pseudandraca Miyata, 1970. Yang (1995) added one species, Andraca flavamaculata Yang, 1995, to the Chinese Andraca fauna. Owada et al. (2002) reviewed three species of Andraca from Vietnam and provided a world checklist. Zolotuhin and Witt (2009) recorded five Andraca species from Vietnam, describing two new species, Andraca stueningi Zolotuhin & Witt, 2009 and Andraca melli Zolotuhin & Witt, 2009, and newly treating two taxa, Andraca trilochoides roepkei Bryk, 1944 and Andraca olivacea olivacens Mell, 1958, as subspecies of Andraca trilochoides Moore, 1865 and Andraca olivacea Matsumura, 1927 respectively. At present, the genus Andraca consists of eight species ranging from the Himalayas to Southeast Asia.
In the present paper, seven Chinese Andraca species are reviewed, including the description of one new species Andraca gongshanensis, sp. n. The early stages of Andraca theae (Matsumura 1909) are described in detail. A key to the seven Chinese Andraca species is provided.
Materials and methodsSpecimens of the new species were collected by light trap. The types of previously described species in the Natural History Museum, London, UK (BMNH) were examined. Other materials examined in this study are preserved in SCAU and HUNAU. Morphological terminology used in descriptions follows Lemaire and Minet (1999).
Taxonomyhttp://species-id.net/wiki/Andraca
Forewing weakly falcate. Ground color varying from shades of brown to sandy grey.
Male genitalia. Uncus apically single-pointed to weakly indented; gnathos with two long, basally broad, upcurved arms; valvae basally broad, sclerotized, long or medium length; aedeagus short with apex truncated, cornuti present or absent.
Female genitalia (Andraca bipunctata). Eighth segment curved deeply, ventral margin of ostium bursae extends posteriorly as a broad bilobed plate, ductus bursae sclerotized distal to mid-point, tapering to half width; distal half unsclerotized with slight torsion, corpus bursae lacking a signum.
Oriental Region, S & E Palaearctic.
Andraca species have sometimes been described in Mustilia (e.g., Chu and Wang 1993, 1996), and misidentification has also been frequent (Chu and Wang 1993, 1996). Andraca was considered to belong to ‘the Mustilia lineage’ of Prismostictinae Forbes, 1955 (Holloway 1987; Minet 1994; Lemaire and Minet 1999; Holloway et al. 2001). Our own unpublished work also shows that Andraca is close to Mustilia Walker, 1865 and Mustilizans Yang, 1995, based on phylogenetic analysis of mitochondrial and nuclear DNA sequences (COI + 18S +28S) (Wang 2010).
Sevastopulo (1938) described the fully grown larvae of the type species. The larvae are gregarious, have short hairs covering the body, and are often heavily parasitized. Pupation is in a thin cocoon of brown silk spun among leaves.

This widely distributed species is rather variable in coloration and size. Moore (1865) described Andraca trilochoides from a brighter and grayish individual. This taxon was later synonymized with Andraca bipunctata by Hampson, ([1893]), an action that was followed by Strand (1924).
Andraca bipunctata is closely related to Andraca angulata Kishida, 1993 (Nepal and India: Sikkim), Andraca theae (Taiwan) and Andraca stueningi (Vietnam). 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.
Larvae of Andraca bipunctata are well-known serious pests of tea trees, Camellia sinensis (Theaceae) (Banerjee 1982; Chang 1989; Chen et al. 1992; Panigrahi 1995; Ho et al. 1996; Upadhyay et al. 2001).

Wang (1995) provide a fine color illustration of a fresh living male. Owada et al. (2002) considered Andraca olivacens from Fukien (= Fujian) to the synonym of Andraca olivacea, whereas Zolotuhin and Witt (2009) treated it as a subspecies thereof. We do not comment further on which of these two alternatives may be the most appropriate status for this taxon because we have not seen the types of Andraca olivacens.
Male: wingspan 37–39 mm, length of forewing 15–18 mm, antenna length 6–8 mm (Fig. 1-C). Head covered with reddish-brown hairs; forewing with black discal spot, smooth outer margin and apically not falcate. Male genitalia (Fig. 2-C): uncus triangular, apical half truncate; valva with two subapical, dorsally-directed projections; aedeagus short, curved slightly without cornuti, external surface without hair-like spines.

Yang (1995) described the species from Zhejiang, China. The species is similarto Andraca olivacea but can be distinguished by the following characters: aedeagus straight; gnathos not prominent. Zolotuhin and Witt (2009) synonymized Andraca nabesan Kishida & Owada, 2002 with Andraca flavamaculata, which they also transferred to Pseudandraca species based on features of the genitalia. We accept the synonymy but do not agree with the generic transfer, because we do not consider that the diagnostic feature of Pseudandraca given by Miyata (1970), a valva with a “long distinct projection” is present in Andraca flavamaculata. We therefore transfer Andraca flavamaculata comb. rev. back to Andraca.
