Papillae anales small, narrowly well-sclerotized both at base and medially, with numerous setae on membranous parts only; posterior apophysis distinctly longer than anterior apophysis; tergite 8 relatively broad, well-sclerotized, with numerous long setae at distal margin; lamella postvaginalis narrow, long, well-sclerotized; ostium bursae opening near posterior margin of sternite 7, membranous; antrum short, membranous posteriorly and well-sclerotized at ductus seminalis; ductus bursae thick, membranous, gradually dilating into corpus bursae; latter ovoid, without signum.

INDIVIDUAL VARIABILITY. Both males ( Figs 1, 2 View Figs 1–8 , 9–12 View Figs 9–16 ) and females ( Figs 13–16 View Figs 9–16 ) vary in the number of yellow, pale yellow or pale orange scales on the head, thorax, legs and abdomen. There is a male ( Figs 11–12 View Figs 9–16 ), in which all black scales on the head, thorax legs and abdomen are replaced with brown to light brown ones. Besides this, the ground colour of the forewing slightly varies from light brown to brown. The colour of the flying and not so fresh specimens is much paler and with less number of yellow scales on the thorax and abdomen. Individual size is variable as follows. Males: alar expanse 13.5–22.0 mm, body length 6.8–9.4 mm, forewing 6.0– 10.1 mm, antenna 3.5–5.0 mm. Females: alar expanse 14.4–20.2 mm, body length 6.8–10.0 mm, forewing 6.5–9.0 mm, antenna 3.4–4.8 mm.

DIFFERENTIAL DIAGNOSIS. This new species belongs to N. myrmosaeformis species group and seems to be the closest to N. cingulata ( Figs 3–4 View Figs 1–8 , 31 View Figs 30–32 ) (type locality: Greece, Parnassus, Kastri), from which it can be distinguished by the colouration of the antenna (black with violet or blue-violet sheen in the species compared, vs. dark brown or brown with bronze-violet or golden-bronze sheen and a few yellow scales externally in N. efetovi sp.n.), frons (dark brown to black with greenish sheen in N. cingulata , vs. yellow in N. efetovi sp.n.), thorax (dorsally entirely black with dark greenish-violet sheen in N. cingulata , vs. tegula with pale yellow or yellow scales in distal half; mesothorax with yellow scales medially; metathorax with two yellow spots medially in N. efetovi sp.n.), legs (mid tibia entirely black with dark blue-violet sheen; hind tarsus exterior-dorsally black with dark blue-violet sheen, interior-ventrally dark brown with bronze sheen and a few dark yellow scales in N. cingulata , vs. mid tibia internally golden-yellow, externally black with greenish-violet sheen with dense admixture of dark-yellow to orange scales and dark yellow to orange pointed scales both subbasally and distally; hind tarsus externally narrowly dark yellow, dorsally, internally and ventrally entirely yellow with golden sheen in N. efetovi sp.n.), and by the presence of orange scales on the tip of the anal tuft in N. efetovi sp.n. (black with greenish-violet sheen in N. cingulata ). Besides this, the background colouration of the forewing in N. efetovi sp.n. is much lighter.

The new species differs from N. hoplisiformis ( Figs 7–8 View Figs 1–8 ) (type locality: “Brussa” [= Turkey: Bursa]) by the colouration of the antenna (yellow in N. hoplisiformis , vs. dark brown or brown with a few golden-yellow scales externally in N. efetovi sp.n.), labial palpus (entirely yellow in N. hoplisiformis , vs. yellow with black scales exterior-ventrally in N. efetovi sp.n.), thorax (patagia with an admixture of yellow scales, metathorax entirely yellow, thorax laterally with a large yellow spot at base of forewing in the species compared, vs. patagia black with greenish-blue sheen, metathorax black with two yellow spots medially, thorax laterally without yellow spot at base of forewing in N. efetovi sp.n.), and abdomen (basal tergite yellow laterally, sternite 1+2 broadly yellow distally, anal tuft yellow in N. hoplisiformis , vs. basal tergite without yellow scales laterally, sternite 1+2 entirely black with greenish-blue sheen, anal tuft black with greenish sheen, with orange scales distally and a few yellow scales dorsally at base in N. efetovi sp.n.).

In addition, the species of the genus differ from each other by the shape of the valva ( Figs 22–25 View Figs 22–25 ) and aedeagus ( Figs 26–29 View Figs 26–29 ).

BIONOMICS. The larval host-plant is Potentilla pedata Willd. ( Rosaceae ). The larva lives in the root where bores a tunnel about 2–3 cm long. It lives during a year and pupates in a cocoon in the upper part of the root. Moth emerged from the beginning of June to the beginning of July. They can be found sitting on flowers of the host-plant or other near flowers with their mid legs extending up ( Fig. 30 View Figs 30–32 ). Males are luring to synthetic sex attractants.

HABITAT. Xerotermic herbaceous steppe on coated soils ( Fig. 32 View Figs 30–32 ).

DISTRIBUTION. At present, this new species is known only from two localities in the surroundings of Belogorsk, Crimea only.

ETYMOLOGY. This new species is named after my friend Prof. Dr. Konstantin A. Efetov (the Vernadsky Crime- an Federal University, Simferopol, Russia), a researcher of the Lepidoptera of the Crimean Peninsula and a specialist in the family Zygaenidae of the world fauna.
