Grados) (genitalia # JGA 431 MUSM) GoogleMaps   ; 1 ♀, idem except (genitalia # JGA 432 MUSM). All in MUSM. [All examined.]  

Diagnosis. Head, patagia, tegulae and dorsal surface of thorax and abdomen, white. Forewing white with the veins brown. Hindwing white. Valvae slightly longer than the uncus. Saccus as a large triangle. Phallus elongated, slightly sinusoidal and somewhat sclerotized. Vesica membranous with presence of one row of strongly sclerotized cornuti.

Description. Male. Head. Proboscis light brown. Palpi predominantly white, not exceeding vertex in length. Frons white, longer than wide. Vertex, occiput and scape white. Ocular ring brown with a bluish hue. Antennae white with brown scales at the base of each flagellomere. Medial rami length approximately three times the width of the shaft. Rami decreasing in length gradually towards the tip of the antennae, being absent distally. Thorax. Dorsal surface of meso- and metathorax, including patagia and tegulae, white. Foreleg coxae white. Foreleg femora, tibia and tarsi white and the inner surface brown. Epiphysis light brown. Midleg coxae and femora white, tibia and tarsi white and the posterior surface brown. Hindlegs white. Forewings. Forewing length 11‒12 mm (n = 5). Dorsally white with light brown veins and a brown costal margin. Ventrally white, with grey scales in the anterior area of the discal cell, on radial veins and in the distal half of median and cubital veins. The brown veins are more contrasting in the distal half, toward the termen. Hindwings. Dorsal and ventral surfaces almost identical, predominantly covered with white scales. On the ventral side, grey scales present between the costal margin and the radial veins. Abdomen. Countertympana on dorsal and ventral side white. Genitalia ( Figs. 43‒46 View FIGURES 43‒46 ). Saccus developed. Tegumen as wide as the vinculum, glabrous. Anterior margin of tegumen with a deep U-shaped invagination, slightly sclerotized. Posterior margin of tegumen straight, membranous in the middle, from which two structures in the form of sclerotized tongues emerge. Uncus unilobed, glabrous, wide at base, acute toward the distal end. Juxta extended, sclerotized, wide at base. Valvae symmetrical, slightly longer than the uncus; in lateral view thin and slightly curved. Toward the distal end, dorsal and ventral processes present. Ventral process membranous and covered with setae. Dorsal process slender, sclerotized and acute. Phallus cylindrical, slightly sinusoidal and somewhat sclerotized. Vesica membranous with a row of strongly sclerotized cornuti. Coremata with additional scale bunches ( Fig. 50 View FIGURES 47‒50 ) at the base of coremata tubes (as in alba   and sericea   , above).

Female. Forewing length 13 mm (n = 2). Similar to males, but medial rami as long as the shaft width. In the forewings the costal margin is white. Genitalia ( Fig. 54 View FIGURE 51‒54 ). Ninth tergite slightly sclerotized. Papillae anales with relatively long setae. Anterior and posterior apophyses of the same size. Ostium and antrum centralized. Antevaginal lamella membranous and postvaginal lamella sclerotized. Ductus bursae wide, flattened, sinusoidal and membranous, except for the distal third of the dorsal side, which is sclerotized. Corpus bursae oval and membranous with small spicules on more than half its surface. Ductus seminalis emerging at the end of the ventral side.

Biology. Unknown.

Distribution. PERU; present in the departments of Junin and Cusco, i.e., in the low montane forest of the Eastern slope of the Andes, 430‒ 690 m.

Etymology. canae   is a feminine adjective in singular genitive which means "of the white".

Remarks. Gloora canae   shows some similarity to G. alba   , G. sericea   and Eucereon vestalis ( Schaus, 1892b)   . However, G. canae   has brown veins. Gloora alba   occurs from Mexico to Venezuela and G. sericea in South-East   Brazil, Argentina and Paraguay; E. vestalis   co-occurs with G. canae   in Peru.
