Amerila astreus (Drury, 1773)

Figs. 2 C-2D

Material examined. INDONESIA, Lesser Sundas, East Nusa Tenggara, Flores Island: Sano Ngoang Lake, geothermal site, primary mountain rainforest , 8º43’1”S, 120 º0’10”E, 23 January 2015, 1♀, Bolotov leg. ( RMBH, voucher no. SPH0694 ); Kanawa Island, scarce forest of Ziziphrus jojoba , 8°29'31"S, 119°45'27"E, 26 April 2011, 1♂, Bolotov leg. ( RMBH, voucher no. SPH0693 ) .

Distribution: India and Sri-Lanka over Nepal, continental China, Taiwan, the Philippines to IndoChina, Indonesia and New Guinea ( Table 1 ).

DNA barcoding: Two sequenced specimens from Flores share two unique COI haplotypes with p - distance of 0.3%. Their nearest neighbors were from Malaysia (p -distance from 0.2 to 0.6%) and from Taiwan (p -distance from 1.1 to 1.4%) ( Table 2 ) that indicates rather recent dispersal of the species from Sundaland to the Lesser Sundas.

Remarks: First record from Flores and its small offshore island (Kanawa).
