Volynkin, Anton V., 2023, Contribution to the knowledge of the genus Siccia Walker (= Aemene Walker, syn. n.) in the Afrotropics with descriptions of seventy-three new species, three new subspecies, and a check-list of Asiatic taxa of the genus (Lepidoptera: Erebidae: Arctiinae: Lithosiini), Ecologica Montenegrina 64, pp. 1-184 : 93

The S. exilisioides species-group

Diagnosis. Members of the species-group are externally similar to the S. pallidata species-group and can be distinguished by the genitalia structures only. The male genital capsule configuration is similar to that of the S. pallidata species-group but differs in the broader and heavily sclerotised cucullus, and the shorter sacculus with a distal process directed dorso-distally whereas it is directed distally in the S. pallidata species-group . The phallus and the vesica structures of the two groups display no remarkable differences. The female genitalia are similar to the S. pallidata species-group but distinguished by the laterally sclerotised posterior section of the corpus bursae, the presence of a broad band-shaped cluster of robust spinules and the appendix bursae situated laterally.
