Scoparia metaleucalis Hampson, 1907: 23 View in CoL ; Li, Li & Nuss, 2010: 8, figs 5 (misidentified), 13, 23 (misidentified). Type locality: Sichuan Province, China.

Diagnosis

Unique by narrow valva, conspicuously convex sacculus ventrobasally, and juxta covered with granules medially and spines laterally in the male genitalia.

Description

Adult ( Fig. 3E View Figure 3 ): Forewing length 7.0– 8.5 mm. Frons and vertex white mixed with grey. Patagium, tegula, and thorax pale brown mixed with white. Forewing suffused with blackish brown scales; antemedian line convex near middle; antemedian stigmata stripe-like; distal discoidal stigma 8-shaped; postmedian line waved, meeting costa and dorsum perpendicularly; subterminal line concave at middle; fringe white, pale brown near base. Hindwing white; fringe concolorous with forewing. Abdomen pale brown.

Male genitalia ( Fig. 5A, B View Figure 5 ): Uncus ovate. Gnathos slender, a bit longer than uncus, armed with tiny dentations. Valva narrow; costa gently convex; apex rounded. Sacculus conspicuously convex ventrobasally and concave ventrodistally; free distal process at about threequarters of valva. Juxta ovate, posteriorly with granules near middle and small spines at lateral sides. Phallus curved slightly, a bit shorter than valva, attached with a piece of membrane covered with dense tiny spines near tip; phallus with two groups of cornuti – one group consisting of many spines arranged in a row, the other group consisting of several spines arranged in a cluster.

Female genitalia ( Fig. 8A, B View Figure 8 ): Papillae anales slightly shorter than apophysis posterior. Tergite 8 about two-fifths as long as apophysis anterior. Antrum broad and short, covered with dense tiny spines, posterior margin about three times as wide as middle of ductus bursae, narrowing towards colliculum. Colliculum sclerotized strongly, posterior half with semicircular protuberance. Ductus bursae long and thin. Corpus bursae ovate, covered with dense tiny spines on left area, armed with dense granules on right area; signum and appendix bursae present.

Distribution

China (Sichuan).

Remarks

The species is varied in the genitalia: the male genitalia of some individuals with the juxta incised on posterior margin, the phallus distally with many strong cornuti arranged in a cluster and a straight row, respectively ( Fig. 5A View Figure 5 ); in contrast, the juxta of some specimens is convex distally, with the tip of phallus only with several cornuti arranged in a cluster and the second group of cornuti much smaller and arranged in a C-shape ( Fig. 5B View Figure 5 ). In the female genitalia, the corpus bursae of some specimens densely covered with tiny spines on left two-thirds of area and granules on right one-third of area, bearing a granular and spinous signum and an ovate appendix bursae ( Fig. 8A View Figure 8 ); in some individuals, the spines covered on the left half of corpus bursae are relatively big, but the signum is strikelike and inconspicuous, the appendix bursae is thumbshaped and much smaller ( Fig. 8B View Figure 8 ). The differing characters above were confirmed as representing intraspecific character variability after sequencing the DNA barcode of seven specimens, the COI sequences of which (DNA nos LW13084, LW13085, LW13086, LW13087, LW13088, LW13089, and LW13090) were represented by a wellsupported cluster ( Figs 1 View Figure 1 and 2 View Figure 2 ).

Furthermore, the association of males and females of S. metaleucalis was established clearly based on the phylogenetic results of the male and female COI sequences ( Figs 1 View Figure 1 and 2 View Figure 2 ). But the female herein is conspicuously different from the prior description ( Li, Li & Nuss, 2010: 8, figs 5, 23) by the following characters: the forewing with an 8-shaped distal discoidal stigma and a waved postmedian line; the female genitalia with a straight colliculum armed by a protuberance at posterior half, and the appendix bursae is much smaller than the corpus bursae. In the previous description, the discoidal stigma was X-shaped and the postmedian line was not waved; the colliculum was curved at anterior one-third, anteriorly with a protuberance, and the appendix bursae was a little smaller than the corpus bursae. The prior description is demonstrated to be erroneous based on the integration of DNA barcoding and morphological approaches, and the female of S. metaleucalis is described for the first time herein.
