Otherwise colour pattern as in male (holotype).

Female genitalia ( Fig. 75 ). Paratype. Genital preparation № OG–048-2018.

INDIVIDUAL VARIABILITY. Both males ( Figs 33– 36 ) and females ( Figs 37–40 ) vary in the number of yellow, pale yellow or 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 yellow scales on the thorax and abdomen. Individual size is variable as follows. Males: alar expanse 17.0–18.0 mm, body length 8.7–10.0 mm, forewing 7.4–8.0 mm, antenna 4.7–5.0 mm. Females: alar expanse 16.0–17.0 mm, body length 8.2–8.7 mm, forewing 7.1–7.5 mm, antenna 4.4–4.6 mm.

DIFFERENTIAL DIAGNOSIS. This new species belongs to Ch. annellata species-group and seems to be the closest to Ch. dumonti ( Figs 41–56 ), from which it can be distinguished by a smaller size (alar expanse 16.0–18.0 in Ch. kalashiani sp.n., vs. 17.0–21.0 in the species compared). Males of Ch. kalashiani sp.n., differ from males of Ch. dumonti by relatively larger external transparent area (divided into five cells between veins R 3 and CuA 1, level to vein M 2 about thrice as broad as discal spot in Ch. kalashiani sp.n., vs. divided into five or even six cells between veins R 3 and CuA 1, level to vein M 2 about 2.5 times as broad as discal spot in Ch. kalashiani ) and smaller posterior transparent area of the forewing (short and not reaching level of cross-vein of hindwing in Ch. kalashiani sp.n., vs. long and exceeding level of cross-vein of hindwing in Ch. dumonti ; cp. Figs 33–36 with Figs 41–48 ). In addition, the males of this new species look somewhat more yellow due to the greater number of yellow scales on the apical area of the forewing and abdomen. Females of this new species can be separated from females of Ch. dumonti by relatively larger discal spot of the hindwing (cp. Figs 37–39 and 49–56 ). Besides this, these two species clearly differ from each other by the structure of both male and female genitalia (compare Figs 65–68 and Figs 69–72 , Fig. 75 and Fig. 76 ).

From Ch. diabarensis Gorbunov, 1987 (type locality: Azerbaijan, Talysh Mts., Zuvand), this new species is distinguishable by the colouration of the hind tibia (pale yellow with golden hue, with white scales both dorso-medially and dorso-distally and dark gray-brown scales with bronze-violet sheen both ventrally from base to base of mid spurs and distally in Ch. kalashiani sp.n., vs. white with an indistinct in male and broad in female black ring with dark violet sheen both basally and at base of apical spurs in the species compared) and forewing (costal margin dark brown with dark blue-violet sheen; anal margin, CuA-stem and discal spot dark brown with bronze sheen; veins within external transparent area dark brown with bronze sheen and a few yellow scales; apical area dark brown with bronze sheen and an admixture of yellow scales between veins R 4 –M 2 in Ch. kalashiani sp.n., vs. costal and anal margins and CuA-stem dark brown with bronze-violet sheen sheen, densely covered with brownish and a few yellow scales masking background colouration, discal spot dark brown to black with dark violet sheen; veins within external transparent area dark brown with bronze sheen and a few yellow scales; apical area dark brown with bronze sheen and an admixture of yellow scales between veins R 4 –M 3 in Ch. diabarensis ), by relatively larger external transparent area of the forewing in male (divided into five cells between veins R 3 and CuA 1, level to vein M 2 about thrice as broad as discal spot in Ch. kalashiani sp.n., vs. divided into four cells between veins R 4+5 and CuA 1, level to vein M 2 about twice as broad as discal spot of Ch. diabarensis ). The host plants of Ch. diabarensis is Marrubium persicum C.A.Mey ( Lamiaceae ).

From Ch. albida Špatenka, 1999 (type locality: Turkey, Taurus Mts., Sertavul pass), Ch. kalashiani sp.n., clearly differs by the presence of yellow scales on legs and wings (white in the species compared) therefore it looks much yellower. The host plants of Ch. albida is Sideritis syriaca L. ( Lamiaceae ).

BIONOMICS. The larval host-plant is Stachys iberica M. Bieb. ( Lamiaceae ). The larva lives in the root where bores a tunnel about 7–9 cm long. It lives during a year and pupates in the upper part of the root. Moths are on the wing from the mid-June to mid-July.

HABITAT. Xerophytic grassy slopes, glades in broadleaved forests at altitudes of about 1400–1800 m above sea level.

DISTRIBUTION. The new species is known from a few localities in Armenia and Azerbaijan within the Daralagez and Zangezur mountain ranges at altitudes of 1400–1800 m.

ETYMOLOGY. This new species is named after my friend Dr. Mark Yu. Kalashian (Scientific Center of Zoology and Hydroecology, National Academy of Sciences of Armenia, Yerevan, Armenia), a researcher of Buprestidae ( Coleoptera ) of the world fauna.
