Cyana karsticola View in CoL sp. n.

( Figs 32, 33 View FIGURES 26–33 , 48 View FIGURES 46–48 , 57 View FIGURES 54–57 )

Type material. Holotype ( Figs ): male, “ Laos, prov. Vientiane | Vang Vieng, 270m, | 18°55’40’’N; 102°24’49’’E | 20.IV.2017 leg. K. Černý ” / “Slide | AV4128ϐ | A. Volynkin ” ( MWM / ZSM, ex coll. CKC). GoogleMaps

Paratypes. LAOS: 7 males, 2 females, same data as holotype, gen. prep. Nos.: AV4129 (male), AV4130 (female) (prepared by Volynkin) ( CKC) GoogleMaps .

Diagnosis. The forewing length is 11.0–12.0 mm in males and 11.5–12.0 mm in females. Cyana karsticola sp. n. ( Figs 32, 33 View FIGURES 26–33 ) is externally vaguely reminiscent of C. griseilinea ( Figs 22–25 View FIGURES 18–25 ) but differs clearly in the smaller size, the grey head, thorax and forewing markings (they are greyish-brown in the congener), the markedly broader and more diffuse ante- and postmedial lines in the male and the thinner and more distinct transverse lines in the female, the interrupted subterminal line in both sexes, and the veins in the postmedial area being less suffused with grey. Additionally, the hindwing of the new species has a discal spot which is absent in the congener. The male genitalia of C. karsticola sp. n. ( Fig. 48 View FIGURES 46–48 ) are most similar to C. bacilla ( Figs 46, 47 View FIGURES 46–48 ), from which the new species is distinguished by the somewhat narrower serrulate plates of the anellus, the longer and broader phallus, and the longer and broader vesica with a shorter and denser lateral cluster of spines, and the broader and bilobate ventral diverticulum bearing two elliptical clusters of more robust spines whereas C. bacilla has a conical ventral diverticulum bearing a single ribbon-like cluster of finer spines. In the female genitalia, C. karsticola sp. n. ( Fig. 57 View FIGURES 54–57 ) differs from C. bacilla ( Fig. 56 View FIGURES 54–57 ) in the markedly longer, narrower and more heavily sclerotised ductus bursae, the broader sclerotised posterior section of the corpus bursae which is more protruding on its left side, the broader anterior section of the corpus bursae bearing smaller signa, and the broader appendix bursae with a longer bulla.

Distribution. Northern Laos (Vientiane Province) ( Fig. 61 View FIGURE 61 ).

Etymology. The specific epithet refers to the habitat of the new species situated in karst mountains ( Figs 58 View FIGURE 58 , 59 View FIGURE 59 ). The name is a noun in the nominative singular in apposition.
