The Lepidoptera fauna of the island of Flores (Lesser Sunda Archipelago, Indonesia) shares a large proportion of endemic species, which may reach 80100% in several groups (Zolotuhin Witt 2005; Nässig et al. 2009; Zolotuhin 2009; Nässig Bouyer 2010; Yakovlev 2015; Spitsyn Potapov 2020; Spitsyn Bolotov 2020). A plethora of new species was described from this island during the last 15 years, e.g. the tiger moth Spilarctia mikeli Bolotov, Kondakov Spitsyn, 2018 (Zolotuhin Witt 2005; Yakovlev 2006; Spitsyn Bolotov 2020a, b, c). This species was described based on a single female specimen collected in West Flores (Bolotov et al. 2018). In the present paper, we describe the male of Spilarctia mikeli for the first time, and illustrate variability of marking patterns of both the male and the female of this species.
