03DD879C9063154A4F8BD953FD7FF8FB.taxon	diagnosis	Diagnosis. Mathania hughesi sp. n. is easily distinguished from all the known congeneric species by having a black band at the distal end of the discal cell from costal margin to the base of cell M 3 - CuA 1 on the forewing upperside (Fig. 1), absent in the other species. The male genitalia of M. hughesi sp. n. (Fig. 2 a, b) is similar in shape to other species of Mathania. However, there are differences in the shape of the valvae that can allow its separation, a somewhat slender uncus, basally broader and distally narrower valva, rounded valval process and basally narrower vesica. Male genitalia in most species of Mathania have a robust uncus and tegumen, and elongate valvae with prominent structures on the inner side (Fig. 3). FIG. 1. Adults. A.

Head primarily black with brown eyes, hairy palpus with whitish brown hair-like scales, antenna dorsally brown and ventrally whitish brown. Body and abdomen black with white hair-like scales, abdomen ventrally light brown. Upperside of wings ground color white. DFW with black apex extending on outer margin to Cu 1 and a black band on distal end of discal cell from costal margin to base of cell M 3 - CuA 1. DHW white. VFW white with apex greenish yellow extending through outer margin to Cu 1, and a dilute black band on distal end of discal cell, similar to that on dorsum. VHW greenish yellow, with yellow costal margin from base to apex, one longitudinal yellow line from wing base through discal cell to outer margin in cell M 2 - M 3, and other longitudinal yellow lines in cells M 3 - CuA 1, CuA 1 - CuA 2 and CuA 2 - A 1. Male Genitalia (Fig. 2 a, b, c): Saccus short and straight, tegumen well developed, uncus short with dorsolateral protuberances at base, valvae with weak dorsal concavity and prominent structures on the inner side (valval process), aedeagus curved downward as shown in Fig. 2 c. Female (Fig. 1 C, D): forewing length 24 - 25 mm (n = 7), color and pattern very similar to that of male, but with slightly darker wings and with black outer wing margin broader at distal end of cell M 3 - CuA 1 on DFW. Female genitalia (Fig. 2 d, e, f): Papillae anales hairy rounded in lateral view, with slightly elongated lobes in apical segment in dorsal view (Fig. 2 e); posterior apophyses longer, ~ 2 × length of anterior apophyses; ductus bursae cylindrical, membranous; corpus bursae membranous, subspherical with sclerotized elliptical dentate signum as shown in Fig. 2 f, and with a larger accessory pouch; ductus seminalis inserted at the base of the ductus bursae.

03DD879C9063154A4F8BD953FD7FF8FB.taxon	etymology	Etymology. This new species is dedicated to Robert (“ Robin ”) A. Hughes (1934 - 1991), in recognition of his valuable observations on the butterflies of the Department of Arequipa and southern Peru, being the first to report this species from the surroundings of Arequipa in the 1950 s. Sadly, Hughes` personal collection of Lepidoptera was lost in the late 1960 s in Arequipa (Hughes, in litt. to GL) FIG. 3. Male genitalia (in lateral view). A. M. leucothea, locality Valparaiso, Chile, PBF collection. B. M. carrizoi, locality Purmamarca, Argentina, PBF collection. C. M. agasicles, locality Gualaceo, Ecuador, PBF collection. D.

03DD879C9063154A4F8BD953FD7FF8FB.taxon	distribution	Distribution. Mathania hughesi sp. n. is known from the western slope of the Andes in Peru, from the Department of Ayacucho in the north, south to the Department of Tacna, between 2300 and 3500 m elevation (Fig. 4).	en	Farfán, Jackie, Lamas, Gerardo, Cerdeña, José (2020): A new species of Mathania Oberthür, 1890 from Peru (Lepidoptera, Pieridae).

03DD879C9063154A4F8BD953FD7FF8FB.taxon	biology_ecology	Host plant. Ligaria cuneifolia (R. et P.) Tiegh. (Loranthaceae). Bionomics. Adults are frequently found in xerophytic-shrub habitats above 2000 m, close to rivers or brooks where the host plant is located, the adults fly around the canopy of trees supporting the hemiparasitic host plant Ligaria cuneifolia, which in Arequipa grows on Schinus molle L. (Anacardiaceae), rarely adults fly at ground level. Oviposition behavior of M. hughesi is very similar to that described by Courtney (1986) for M. leucothea in Chile: « … Egg-laying is brief when it occurs: the wings fully closed (always open during “ testing ” contacts), the abdomen bent under, and one to several eggs rapidly deposited. … ». Larvae of M. hughesi were found feeding close to the shoot tips on the underside of leaves of L. cuneifolia,; the larvae are solitary, cryptic and difficult to find on the host plant. The immature stages (Bravo et al. unpublished data) are similar to those of M. leucothea (Braby & Nishida 2007). Mathania hughesi around Arequipa appears to be univoltine, with abundant adults flying between June and August, and very few individuals between December and April. The latter period swith when immatures were found (March), which suggests that M. hughesi take advantage of rainy season of the southwestern slopes of the Andes (November to March) for development its, presumably due to food availability, because several dried plants of L. cuneifolia were observed during dry season.	en	Farfán, Jackie, Lamas, Gerardo, Cerdeña, José (2020): A new species of Mathania Oberthür, 1890 from Peru (Lepidoptera, Pieridae).
