A REVIEW OF TIGER MOTHS (LEPIDOPTERA: EREBIDAE: ARCTIINAE: ARCTIINI) FROM FLORES ISLAND, LESSER SUNDA ARCHIPELAGO, WITH DESCRIPTION OF A NEW SPECIES AND NEW SUBSPECIES
The Wallacean Region is considered a unique evolutionary hotspot, but the current knowledge of lepidopteran faunas on certain islands is very far from being complete. Here we present a preliminary checklist of the Arctiini fauna of the Flores Island based on available collection materials and a review of the body of literature. In total, for the island fauna we list 22 tiger moth species, with eight newly recorded species. Among novel records, local endemic Spilarctia mikeli Bolotov, Kondakov & Spitsyn sp. nov. and Aloa cardinalis danau Bolotov, Kondakov & Spitsyn ssp. nov. were discovered. Additionally, several taxa with broad ranges such as Amerila astreus, Creatonotos gangis, Euchromia horsfieldi, Lemyra maculifascia, Nyctemera distincta and Utetheisa pulchelloides were new for the island fauna. In general, 15 taxa are prospective endemic Wallacean elements, among which seven taxa are unknown outside the Flores Island: Orhantarctia cymbalophoroides, Lemyra everetti, L. floresina, Aethalida owadai floresiensis, Nyctemera scalarium regalis, Spilarctia mikeli sp. nov. and Aloa cardinalis danau ssp. nov. Our findings reveal that the tiger moth fauna of the Flores Island has rather moderate level of endemism, with only 32% of putative endemic taxa.
