“…13). In Lepidoptera, these modified scales are known to produce scent, which is spread with the help of the tufts as part of a courtship strategy in which males release pheromones to attract females (Barth 1960;Boppré 1989;Andersson et al 2007). Once Viuria males possess these structures, it is expected that they perform the same function.…”

The taxonomy of the Neotropical Carcharodini genus Viuria Grishin, 2019 (Lepidoptera: Hesperiidae: Pyrginae) is presented. Two new species are described: Viuria inanna sp. nov. from south-southeastern habitats Brazil and Paraguay, and Viuria acadia sp. nov. from Brazil and Ecuador. Illustrations of adults, including morphology of secondary sexual organs in males, male and female genitalia, diagnoses, remarks, and updated geographical distributions are also provided for all species.

Pseudaletia unipuncta (Haw.) males, experimentally deprived of hairpencils (male-specific scent organs), were less acceptable to females than were intact males. The degree to which females discriminated against males lacking hairpencils depended on the experimental protocol. When females were placed with males before scotophase onset, they tended to evade repeatedly and/or terminate genital contact with hairpencil-less males before eventually copulating, although this tendency was not statistically significant. When males were introduced after females had initiated calling, females refused hairpencil-less males significantly more often than intact ones. The incidence of copulation by hairpencil-less males was also lower than that of intact males, significantly so in one of the two populations tested. Neither copulation duration nor the dimensions of the cuticular portion of the spermatophore were correlated with the presence of hairpencils. Yet in all cases, females that mated with hairpencil-less males were more fecund and laid more fertile eggs than those mated to intact males. Hairpencil eversion could not be seen during courtship, nor did females show any obvious change in calling behaviour in response to scent from a freshly excised hairpencil. However, gas chromatographic analysis of hairpencils showed a decrease in titre of two scent components, acetic acid and benzaldehyde, just before the moment of genital contact between male and female, indicating that the pheromone was released at this time. These results suggest that P. unipuncta male pheromone facilitates female acceptance of males. The hypothesis that male pheromone carries information about the quality of a courting male is discussed in relation to recent work on arctiids, nymphalids, pierids and pyralids. An appendix of lepidopteran species possessing male scent structures is included.
