Agrisius cernyi sp. n.

( Figs 9, 10 , 33 , 41 )

Type material. Holotype ( Figs 9 , 33 ): male, “N. Thailand, Chiang Mai, Doi Inthanon-NP, 1416m, 18°30′59′′N, 98°28′13′′E, 7.–8.V.2008 leg. K. Černý ” / “Slide AV5608 A. Volynkin ” ( WIGJ).

Paratype: THAILAND: female, W Thailand, Tak, Doi Mussoe , 821m, 16°45.317′N, 98°55.438′E, 11. V .2008, leg. K. Černý, gen. prep. No.: AV5607 (prepared by Volynkin) ( CAV) .

Diagnosis. The forewing length is 22.0 mm in the holotype male and 21.5 mm in the paratype female. The new species is externally reminiscent of A. epidela and A. kachina but is distinguished by the somewhat smaller size and the markedly less intense dark suffusion on the hindwing veins. Additionally, compared to A. kachina , A. cernyi has a somewhat larger discal spot of the forewing. The male genital capsule of the new species is most similar to that of A. kachina but differs in the slightly longer branches of the uncus, the thicker dorsal process of the sacculus, and the distally thicker ventral process of the sacculus. The phallus of A. cernyi is markedly shorter and narrower than in A. kachina . In the vesica of the new species, the distal diverticulum is conspicuously longer than in A. kachina . In the female genitalia of A. cernyi , the postvaginal plate is longer and posteriorly rounded (whereas it is trapezoid with rounded corners in the congener), and the antrum is narrower. Additionally, the signa bursae of the new species are somewhat narrower anteriorly than in A. kachina .

Distribution. The new species is known from North and West Thailand (Chiang Mai and Tak Provinces).

Etymology. The species is named after Dr Karel Černý, a prominent lepidopterist, expert in Palaearctic and Oriental Arctiinae , collector of the type series and friend of the senior author.
