Type species: Dactylissus armillarius sp. n. FIGURES 10–12. Dactylissus armillarius gen. et sp. n. 10—male, holotype, head, pro-, and mesonotum, in dorsal view; 11—same, face; 12—female, paratype, hind margins of VI–VII sternites. Description. Metope wide, convex, with median carina running from its upper margin but do not reaching the metopoclypeal suture ( Fig. 11 ). Postclypeus slightly flattened dorso-ventrally, with no carinae. Coryphe transverse, twice as wide as long medially, with no carinae; anterior margin obtusely anguately convex; posterior margin concave ( Fig. 10 ). Fore wings elongate, with narrow hypocostal plate ( Fig. 13 ). Basal cell narrowly oval. Sc+R 2 (furcates near to basal cell). Anterior branch of radial vein rather short, it runs on protuberance of wing surface. M 4, firstly furcates near to wing middle. CuA 2, furcates near to wing middle. Clavus long (3/4 as long as whole wing), opened (Pcu + A1 runs to the apex of clavus). Many secondary veins are presented between the main elongate veins. Hind wings well developed, almost as long as fore one, 3-lobed with 2 deep and 1 weak marginal clefts ( Fig. 14 ). Costal margin with a coupling lobe. Basal cell wide. Sc+R 2 (furcates after the coupling lobe), irm 1, M 1, imcua 1, CuA 3 (anterior branch furcates apically, posterior branch fused apically with CuP and flattened), Pcu 1, A1 2 (posterior branch fused medially with Pcu), A2 1. Posterior branch of first anal vein and second anal vein reaching marginal clefts. Hind tibia with 2 lateral spines in apical half and with 7 apical spines. First metatarsomere with 2 latero-apical and 9 intermediate spines arranged in arc. Female genitalia. Hind margin of sternum VII convex medially ( Figs 12 , 33 ). Anal tube elongate. Gonoplacs nearly triangular shaped in abris, convex. Etymology. Generic name is derived from the combination of Greek “δακτύλιος” (finger) and generic name “ Issus ” referring to bizarre structure of male phallobase.
