Aemene taprobanis (Walker, 1854)

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 : 19

The S. taprobanis species-group

Diagnosis. The male genital capsule of the species-group is characterised by the relatively narrow and distally tapered valva with a short and weakly sclerotised ventral costal lobe lacking processes, and a cucullus bearing two short ventral processes. An additional, distal process of the cucullus is present in certain species. The phallus is elongate, narrow, and medially upcurved. The vesica is sack-like with fields of graniculi and, in most species, also bears robust separate cornuti. In the female genitalia, the ductus bursae is elongate, dorso-ventrally flattened and sclerotised. The corpus bursae is posteriorly gelatinous or bearing sclerotised plates and spines. The anterior section of the corpus bursae bears elliptical or band-like signa. The appendix bursae is elongate and distally helicoid in most species, situated postero-laterally.

Note. Some of the Asiatic taxa of the species-group have recently been revised and described by Volynkin (2021).
