description: Nagehana maulina Urra sp. nov.
(Figs. 11, 12, 29, 30, 46, 47).
Diagnosis. Nagehana maulina differs from N. rustica, the type species, mainly by the presence of juxta lateral lobes, structures absent in N. rustica (Clarke 1978). The color pattern of N. maulina is similar to that of N. chagualphaga, since both species have a white FW with a dark gray basal and costal spot. N. maulina can be distinguished by examining the genital structures of the male and female. In N. maulina the lobes of the juxta have thick setae, the cucullus of the valva has abundant thick hair-like setae and in the female the antrum is subconical and the posterior end of the ductus bursae is sclerotized. In N. chagualphaga the lobes of the juxta are somewhat capitate, without setae, the cucullus of the valva has simple setae and in the female the antrum is tubular and the ductus bursae membranous (Beéche 2003).
