Anania stachydalis ( Germar, 1821)

( Figs. 1E , 3E )

Pyralis stachydalis Germar, 1821: 18 , fig. 18. TL: Germany, Braunschweig [Brunsuiga].

Anania stachydalis: Leraut, 2005: 127 .

Material examined. 1 female, Chungju, CB: Chungju, 2020.05.22, (Kim SS) .

Diagnosis. Anania stachydalis can be diagnosed by the dark brownish forewing with weakly dentate and strongly outwardly projected postmedial line, the broad central fascia with a blackish dot and a lunular discal dot, and the dark brown horizontal lines on subtermen, and the dark brownish hindwing with yellowish markings on central fascia and the strongly outwardly projected postmedial line. This species is externally similar to A. verbascalis (Denis and Schiffermüller, 1775) , but can be distinguished by the relatively short lunular discal dot and large blackish dot on the central fasica of the forewing and more blackish markings on the basal and central part of the hindwing.

Description. Wingspan 18mm. Head. Antenna filiform, frons broad, covered with light ochreous scales; maxillary palpi minute, brown; labial palpi long, about twice to eye diameter, 1 st segment whitish, 2 nd segment laterally tinged with light brown scales. Body whitish. Forewing dark brownish in ground color; antemedial line dark brown, weakly undulating, slightly slanted outward; postmedial line dark brown, costal and medial part strongly projected outward; central fascia tinged with yellow scales, strongly tapered from costa to median, a large blackish or dark brown dot close to the costal part of the antemedial line, discal dot lunular, blackish; subtermen with dark brown horizontal lines on veins; termen dark brown with light brown dots in different size, the largest dot near apical streak. Hindwing dark brownish in ground color; basal and medial part with light yellowish dots; postmedial line weakly dentate, medially strongly projected outward; subtermen with light yellowish dots; termen dark brown with light yellow dots. Female genitalia. Papilla anales small, rounded; posterior apophyses thin, slender; anterior apophyses basally thin, slender, the same as long as posterior apophyses; ostium bursae broad, bowl-shaped, dorsally with a pair of large triangular processes, medially with band-shaped horizontal sclerotization, centrally slender sclerotization; ductus bursae long, coiled more than four times, weakly sclerotized colliculum anterior to ostium bursae; corpus bursae ovate, laterally with appendix bursae, signum large rhomboid sclerotized process.

Distribution. South Korea, Europe.

DNA barcoding. One specimen from South Korea ( OK501201 ) was sequenced. The intraspecific genetic variance in A. stachydalis was 0.8% (±0.4 SD) and the average genetic difference between A. stachydalis and its close relative, A. verbascalis was 8.7%.

Remarks. The genus Anania comprises 117 species worldwide, predominant in Afrotropical and Neotropical regions and the unique synapomorphy of the genus is the cone-shaped central structure in the antrum of female genitalia ( Leraut, 2005; Tränkner et al., 2009; Mally et al., 2019). Furthermore, Tränkner et al. (2009) identified the synapomorphies of the genus: the apodeme of preaephallus with asymmetrically sclerotized and an elongated sclerite in the male genitalia. In South Korea, 13 species of Anania are recorded including A. albeoverbascalis and A. stachydalis . The larvae feed on Stachys (Lamiaceae) in Europe.
