In this study, we reviewed and described the detailed taxonomic description of three species caricae Fabricius, 1775; ficus (Fabricius, 1775) and plaginota (Butler, 1875) of genus Asota Hübner. First time detailed diagnoses for the genera and studied species were provided along with the male and female external genitalia. Furthermore, we examined the static allometry of morphological and external genitalic traits in males and females species for the first time from India. One-size-fits-all assumes that static allometry slopes for male genitalia will be consistently lower than 1.0 even also less that other body parts (morphological traits). The relationship between genitalic traits and body size was generally negative-allometric both in males and female with no significant differences from 1.0. In male A. ficus, second segment of labial palp and A.plaginota, fore-tibia shows positive allometry. In female A. caricae, abdomen and fore-tibia; A. ficus, fore-femur and mid-femur and in A. plaginota, first segment of labial palp show positive allometry. The coefficients of variation for almost all the structures in the males were low, not exceeding 10%. Genitalic traits showed significantly lower CV than somatic traits in males. In females, morphological traits resulted lower CV than genitalic traits but with no significant difference in all the three examined Asota species. On the basis of allometry results for genitalic traits in males, we can say that there were different sexual selection mechanisms for these studied species. The present findings reveal that male genital size is not stable within single populations of diverse taxa.
