Siccia imana, a new species from Rwanda (Lepidoptera: Erebidae: Arctiinae)

The genus Siccia Walker, 1854 is a member of the subtribe Cisthenina Bendib Minet of the tribe Lithosiini Billberg (family Erebidae Leach, subfamily Arctiinae Leach) being widely distributed in the Afrotropics. Members of the genus are small or medium-sized moths with similar external appearance (whitish or grey wing coloration with blackish pattern consisting of spots and transverse lines). The check-list of the genus was provided by Kühne (2007), two additional species were described by Ivinskis Saldaitis (2008). Currently the genus includes 20 valid species with very different male and female genitalia structures, and the generic and subgeneric structure of this group needs revision (Volynkin László, in prep.).
