SCOPARIA GIBBOSA LI SP. NOV.

( FIGS 1–2 , 3D , 7C )

Diagnosis

Unique by antrum conspicuously convex at posterior two-fifths in the female genitalia.

Description

Adult ( Fig. 3D ): Forewing length 8.0–9.0 mm. Frons and vertex white mixed with pale brown. Patagium and tegula pale brown. Thorax white mixed with pale brown. Forewing suffused with sparse blackish brown scales; antemedian line lined with dense black scales on outer side, distinctively convex near middle, curved inwards near dorsum; antemedian stigmata ovate; distal discoidal stigma X-shaped; postmedian line waved, meeting costa and dorsum perpendicularly; subterminal line concave at middle, angled outwards near dorsum; fringe white mixed with grey, pale brown near base. Hindwing white; fringe white, mixed with grey near base. Abdomen grey.

Female genitalia ( Fig. 7C ): Papillae anales nearly as long as apophysis posterior. Tergite 8 about half as long as apophysis anterior. Antrum conspicuously convex at posterior two-fifths; posterior margin concave, then broadening towards posterior two-fifths, remaining narrowed. Ductus bursae nearly straight, broadening near corpus bursae. Corpus bursae ovate, left two-fifths longitudinal area with dense tiny spines, right one-fifth longitudinal area covered with dense granules; signum stripe-like; appendix bursae rounded.

Male: Unknown.

Holotype

Female: China, Sichuan, Hailuogou Glacier , near no. 1 glacier, ∼ 3000 m a.s.l., 15 August 2012, W. Li and L. Huang leg., prep. gen. no. LW12009 .

Paratypes

Ten females, same locality as the holotype except dated 14–18 August 2012, prep. gen. no. LW12092 , DNA nos L13046 , L13048 , L13049 , L13050 , L13051 , L13106 , and L13107 ( Figs 1 and 2 ).

Distribution

China (Sichuan).

Etymology of specific epithet

From the Latin gibbosus (= convex), referring to the conspicuously convex antrum in the female genitalia.

Figure 1. Neighbour-joining tree deduced from the cytochrome c oxidase subunit I (COI) gene sequences using MEGA 5. Sequences were corrected with the Kimura two-parameter substitution model. Codon positions included were 1st + 2nd + 3rd + noncoding. Values represented at the nodes of branches are bootstrap values (1000 replicates).
