Diagnosis
See Bassi (2017[1]: 55); Fig. 25 shows female genitalia variation compared with the holotype (Bassi 2017[1]: fig. 3) and with C. europaeicaBłeszyński 1965[2] (Fig. 26). Like the females the males are also smaller (on average 25–26 mm) than those of C. europaeica (on average 28–30 mm). In the forewing the medial band of the longitudinal streak is darker and slightly larger, along the costa the subapical dot is larger and extending closer to the apex, and the fringes are white, tipped brown as opposed to white with medial and apical grey brown bands in C. europaeica. The hind wing is brown as opposed to pale grey brown in C. europaeica. In the male genitalia (Figs 9, 15, 17) the phallus lacks the subapical tooth typical of C. europaeica (Figs 10, 16, 18).
Description of the male
(Fig. 5). Wingspan 25 mm. Labial palpi 3 times longer than widest diameter of eye, white, outer edge bronze brown. Maxillary palpi basally bronze brown, then white. Antennae thickened, brown with bronze brown costa and first segment dorsally white. Frons subconical, slightly produced, white. Ocelli and chaetosemata well developed. Head white, bright brown around chaetosemata. Patagia medially white, laterally brown. Tegulae brown. Thorax white bordered brown. Forewing ground colour brown; costa brown with large subapical white streak; longitudinal streak white, distally enlarged and edged black brown; medial band distally widening, postmedial band equal in width; narrow streak along 1a+2a vein white; dorsum white basally; terminal line dark brown with four black dots; fringes white, tipped brown; underside bronze brown with costa paler. Hindwing brown; fringes white; underside brown. Legs with inner edge white and outer edge pale bronze brown; claws black; pairs of tibial spurs of different length, the distal smaller than proximal. Abdomen bright brown with anal tuft yellow brown.
Male genitalia (Figs 9, 15, 17). Uncus narrow, apically downcurved and pointed; gnathos clearly longer than uncus, with triangular and hooked apex; tegumen subrectangular, shorter than valva; juxta subtriangular, basally enlarged; vinculum stout, subrectangular; pseudosaccus well developed; valva slender, distally triangular, with medial process flat, long and slender; costa with strongly pointed and upcurved basal process, shorter than valva; phallus longer than valva, medially arched, apically sclerotized along lower edge; vesica with several spinulae and scobinations.
Biology
Host-plant and early stages unknown. The holotype was collected in the daytime in cloudy weather conditions, whereas the vast majority of the specimens was attracted to artificial light in a xeromontane habitat (Fig. 29).
Remarks
The female holotype of C. apenninica was collected about 100 km south of the population at Monte Terminillo. The species appears to be an endemic of the Central Italian mountains, with the northern and southern limits of its distribution still to be fully investigated.
