Tolpia qiongensis sp. n.

( Figs. 4 , 46 )

Type material. Holotype: female, China, Prov. Hainan, Baoting, Qixianling, Pailiao Village , 26.iv.2013, Y.H. Sun et al., genit. prep. HHL-3624-2, coll. NEFU . Paratype: 1 female, same data as holotype, genit. prep. HHL-3624-2s (in tube) .

Diagnosis. This species is superficially similar to T. fyani Fibiger, 2007 ( Fig. 3 ), but can be distinguished from it by the following set of characters: The head and thorax are white grey; the abdomen is dark brown, mixed with yellow (in T. fyani the head brownish-black, the thorax and abdomen dark brown); the ground colour of forewing is light brownish grey, mixed with brown and with black graining (in T. fyani it is dark brown, mixed with black); the forewing base without a small black dot (in T. fyani it is with a small black dot); the antemedial line is brown, indistinct, waved, and presents as two small black dots on the costal margin above the cell (in T. fyani the antemedial line is distinct, black, waved); the postmedial line is brown, indistinct, presents a black inverted triangle on the costal margin (in T. fyani the postmedial line is darker and interrupted, with only a short black streak on the costal margin); the subterminal line is smoke black, waved, indistinct (in T. fyani the subterminal line is black, and interrupted); the hindwing is grey, the veins are faintly visible (in T. fyani the hindwing is dark brown, mixed with black, and the veins are not visible). In the female genitalia the ovipositor is tube-shaped, broad, and thick (in T. fyani ( Fig. 45 ) the ovipositor is quadrangular, narrow, and thin); the apophysis anterioris is 3/5X as long as apophysis posterioris (in T. fyani the apophysis anterioris is 7/8X as long as apophysis posterioris); 7 th abdominal segment inverted, tongueshaped (in T. fyani it is inverted, nipple-shaped); the antrum is tube-like, smoothly curved (in T. fyani it is tapered, strongly curved); the ostium and ductus bursae are 13/8X as long as corpus bursae (in T. fyani the ostium and ductus bursae are 11/10X as long as corpus bursae); the corpus bursae is short, drop-shaped, the left and right arms of the transverse line of the signum are equal (in T. fyani corpus bursae is long, drop-shaped, the length of the transverse line of the signum on the left side is shorter than on the right).

Description. Adult ( Fig. 4 ). Wingspan 13.0 mm. Head and thorax whitish grey; abdomen dark brown, mixed with yellowish. Forewing light brownish grey, mixed with brown and black scales; base of forewing without small black dot; basal line slender, short and brown, with small black dots on both ends; antemedial line brown, indistinct, waved, presents with two small black dots on costa and costal margin of cell; median line absent; postmedial line brown, indistinct, smoothly curved, presenting as black inverted triangle dot on costal margin; subterminal line smoky black, waved, indistinct; terminal line a row of small black dots; fringe yellowish grey; basal and antemedial regions light grey, other regions darker; reniform spot indistinct. Hindwing grey, mixed with dark grey scales; discal spot darkly tinged, blurred; fringe lighter than ground colour.

Male genitalia. Unknown.

Female genitalia ( Fig. 46 ). Ovipositor tube-shaped, broad, thick.Apophysis anterioris very slender 3/5X as long as apophysis posterioris. 8 th abdominal segment very narrow, slightly sclerotized, ventrally fused with 7 th segment. 7 th abdominal segment heavily sclerotized, broad, with an inverted tongue-shaped. Antrum tube-shaped, displaced laterally left, smoothly curved. Ostium groove-shaped. Ductus bursae slender and straight, ostium and ductus bursae 13/8X as long as corpus bursae. Corpus bursae short drop-shaped, membranous; signum medially cross-shaped, longitudinal line of signum shorter than transverse line; left and right arms of transverse line are equal.

Etymology. The species name is refers to Hainan Province which is called “Qiong” for shortness in Chinese.

Distribution. China (Hainan Prov., Baoting, Qixianling, near Pailiao Village). The species was collected in the tropical rainforest zone.
