Female genitalia ( Fig. 74 ). Paratype. Genital preparation № OG–049-2018.

INDIVIDUAL VARIABILITY. Males of this new species have two colour forms. They are not clearly delineated, but one is lighter, like the holotype described above ( Figs 17–18 ), and the other is more yellow ( Figs 19–22 ). Yellow specimens are much less common. Among paratypes there are no more than 10 % of them. There is a male ( Figs 23–24 ), in which tergites 2–7 each with a broad yellow stripe and abdomen ventrally practically entirely pale yellow. Females ( Figs 25–32 ) vary in the number of yellow and yellow-orange scales on the head, thorax, legs and abdomen.The colour of the flying and not very fresh specimens is much paler and with less number of bright scales on the thorax and abdomen. Besides this, the external transparent area of the forewing is slightly variable as well (cp. Figs 17 and 21 , and 25 and 29). Individual size is variable as follows. Males: alar expanse 16.5–20.5 mm, body length 9.6– 11.5 mm, forewing 7.4–9.2 mm, antenna 5.1–5.4 mm .. Females: alar expanse 16.8–21.0 mm, body length 10.2–11.6 mm, forewing 7.5–9.2 mm, antenna 4.5–5.1 mm.

DIFFERENTIAL DIAGNOSIS. This new species belongs to Ch. annellata species-group. A distinctive feature of the species of this group is that they look very similar to each other, but they differ quite well in the size of the transparent areas of the forewing, and, very importantly, in the host-plant of the larvae. Some species of the group are found sympatrically.

Ch. efetovi sp.n. seems to be the closest to Ch. dumonti ( Figs 41–56 ) (type locality: France, Alpes-Maritimes, Valdeblore), from which it can be distinguished by somewhat smaller size of the transparent areas of the forewing (posterior transparent area short and not reaching level of cross-vein of hindwing; external transparent area rather large with rounded distal margin, divided into four, very rarely into five ( Figs 21, 23 ) cells, level to vein M 2 about 1.75 times as broad as discal spot in males of Ch. efetovi sp.n., vs. posterior transparent area long and reaching level of cross-vein of hindwing; external transparent area large, roundish, divided into five cells, level to vein M 2 about 2.0–2.5 times as broad as discal spot in males of Ch. dumonti ; posterior transparent area undeveloped; external transparent area small, round, divided into three cells, level to vein M 2 about as broad as discal spot in females of Ch. efetovi sp.n., vs. posterior transparent area short and vestigial; external transparent area large, oval or roundish, divided into 3–5 cells, level to vein M 2 about 1.5–2.0 times as broad as discal spot in females of Ch. dumonti ). The host plants of Ch. dumonti are Stachys recta L., S. atherocalyx K.Koch , S. cretica subsp. bulgarica Rech.f. (as S. thracica auct .), S. plumose Griseb. ( Lamiaceae ).

From Ch. annellata (type locality: “Asia, Tlos” [= Turkey, Mugla Prov., Tlos]), this new species clearly differs by a larger size (alar expanse 16.5–21.0 in Ch. efetovi sp.n., vs. 12.0–18.0 in the species compared) and more developed external transparent area of the forewing (external transparent area rather large with rounded distal margin, divided into four, very rarely into five ( Figs 21, 23 ) cells, level to vein M 2 about 1.75 times as broad as discal spot in males of Ch. efetovi sp.n., vs. external transparent area large, elongate, divided into three, very rarely into four cells, level to vein M 2 about 1.5 times as broad as discal spot in males of Ch. annellata ; external transparent area large, elongate, divided into three cells, level to vein M 2 about 1.2 times as broad as discal spot in males of the species compared). The larvae of Ch. annellata live in roots of Ballota nigra L. ( Lamiaceae ).

From other species of the Ch. annellata species-group, Ch. efetovi sp.n. is distinguishable by the larger size and more developed transparent areas of the forewing.

BIONOMICS. The larval host-plant is Marrubium peregrinum L. (= M. praecox Janka ) ( Lamiaceae ). It is very likely that M. vulgare L. can also be a host-plant of this species in Bulgaria and Romania [ Špatenka et al., 1999: 362]. The larva lives in the root where it bores a tunnel about 5–8 cm long. Its life cycle is annual. Pupation takes place in the upper part of the tunnel in the upper part of the root or lower part of the stem. Moths fly out from the end of June to the second half of July. They can be found sitting on flowers or flying slowly in the thickets of host-plants. Males were collected using synthetic sex attractants for Synanthedon vespiformis (Linnaeus, 1761) produced by PHEROBANK ®, Wijk bij Duurstede, the Netherlands. They are attracted exclusively from 16:30 to 19:00 local time.

HABITAT. Very diverse open biotopes, but with the obligatory presence of the host plant: herbaceous steppes, abandoned lands, roadsides, clearings in deciduous forests, etc.

DISTRIBUTION. At present, this new species is known from a lot of localities in Crimea, North Caucasus and Volgograd Region (see material). In addition, references to the whereabouts of Ch. oxybeliformis in Bulgaria [ Laštůvka, 1983] and Romania [Popesku-Gorj et al., 1958] should refer to this new species.

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