SCOPARIA LONGISPINA LI SP. NOV.

( FIGS 1–2 , 3C , 4C )

Diagnosis

See the diagnosis of S. tribulosa .

Description

Adult ( Fig. 3C ): Forewing length 7.0– 7.5 mm. Frons and vertex white mixed with pale brown. Patagium and tegula pale brown. Thorax white mixed with grey. Forewing suffused with sparse blackish brown scales; antemedian line lined with dense black scales on outer side, slightly oblique outwards; antemedian stigmata stripe-like; distal discoidal stigma 8-shaped; postmedian line meeting costa and dorsum perpendicularly; subterminal line gently concave at middle; fringe white, pale brown near base. Hindwing white; fringe concolorous with forewing, except lighter below base. Abdomen pale brown.

Male genitalia ( Fig. 4C ): Uncus narrow at base, broadening towards middle, then tapering to blunted apex. Gnathos slightly shorter than uncus, pointed apically. Valva narrow at base, broadening towards rounded apex; costa with small process near base, convex near twofifths. Sacculus gently concave at distal one-third of ventral margin. Juxta ovate, distal quarter narrowed towards blunted tip. Phallus straight, slightly shorter than valva; cornuti composed of two thin and long spines, shorter cornutus arising near base of long one.

Female: Unknown.

Holotype

Male: 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. LW12044 , DNA no. L13071 ( Figs 1 and 2 ).

Paratypes

Twelve males, same locality as the holotype except dated 14–16 August 2012, prep. gen. nos LW12045 and LW 12051 , DNA nos L13072 , L13073 , and L13099 ( Figs 1 and 2 ).

Distribution

China (Sichuan).

Etymology of specific epithet

From the Latin longispinus (= long spine-shaped), referring to the cornuti that is long and spine-shaped in the male genitalia.

Remarks

The male genitalia capsule of the new species is similar to S. uncinata and S. tribulosa sp. nov., but can be distinguished from them based on the characters given in the diagnosis of S. tribulosa sp. nov.

Codon positions included were 1st + 2nd + 3rd + noncoding. Values represented at the nodes of branches are bootstrap values (1000 replicates).
