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 Our own unpublished work also shows that Andraca is close to Mustilia Walker, 1865 and Mustilizans Yang, 1995, based on phylogenetic analysis of mitochondrial and nuclear DNA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.

Male (China): wingspan 42–45 mm, length of forewing 21–23 mm, antenna length 6–8 mm (Fig. 1-A). Male genitalia (Fig. 2-A): uncus broad, duck beak-shaped; gnathos long, finger-shaped; vesica with a cluster of strong spinose cornuti

Female genitalia: see above under generic entry.

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).

Male: wingspan 36–38 mm, length of forewing 16–20 mm, antenna length 5–7 mm (Fig. 1-B). Hindtibia with two pairs of spurs; hindwings with Rs and M1 connate. Male genitalia (Fig. 2-B): uncus thick and round; valva simple, basal half broad and terminal half narrow; distal margin of aedeagus with strong lateral spines; vesica with a cluster of spinose cornuti.

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.

Male: wingspan 46–48 mm, length of forewing 22–24 mm, antenna length 5–8 mm (Fig. 1-E). Antenna bipectinate except apex. Wings ground color dark brow with dark brow fasciae and reddish-yellow patterns, which is consisting of antemedian, discocellar, postmedian fascia, and reddish-yellow patterns nearly placed on the wholly wings but termen. Forewing apex falcate; outer edge smooth and straight; tornus almost rectangular. Hindwing with anal margin straight; outer margin angled at vein M3, straight above and below this.

Male genitalia (Fig. 2-E): uncus long with wedge-shaped apex; tegumen broad; gnathos very well developed, arms upcurved; valvae basally broad with many long setae, strongly sclerotized, caudally constricted to a spatulate apex; sacculus broad, without a dorsal spike; aedeagus short but strong and straight, distally with a large number of spines.

The specific epithet refers to the type locality(Gongshan Mountain, China).

This new species is very similar to Andraca flavamaculata, but can be distinguished by the following characters of the male genitalia: Andraca gongshanensis, sp. n. with uncus apex wedge-shaped, apex of valva constricted and truncate, sacculus without a strong dorsal spike. And Andraca flavamaculata with uncus apex finger-shaped, apex of valva boot-shaped; sacculus broad, with a strong dorsal spike.

Externally, Andraca gongshanensis is paler than Andraca flavamaculata.

Male: wingspan 37–39 mm, length of forewing 15–18 mm, antenna length 5–7 mm (Fig. 1-F). Antenna bipectinate except apex. Head thinly covered with brown-green hairs. Forewing: apically bluntly pointed; outer edge smooth and straight, tornus nearly rectangular. Hindwings distinctly angled at vein M3, straight above and below this.

Male genitalia (Fig. 2-F): uncus bluntly triangular with long hairs; tegumen broad; gnathos with two extremely medially swollen arms; valvae flattened, strongly sclerotized, apex narrower and truncate with a dorsally directed projection from the middle; saccus short and broad; aedeagus short, strongly curved, with a compact group of long, thick needle-shaped cornuti on dorsal surface.
