The Tigermoths (Erebidae, Arctiinae, Arctiini) of Papua Indonesia
by Rob de Vos
Amerila crokeri (MacLeay, 1826)
[Euprepia crokeri MacLeay, 1826] (type not located but probably in Australia)
ssp. bakeri (Rothschild, 1914) [Rhodogastria bakeri] (type: New Guinea, not located)
Rhodogastria kajana Bryk, 1913 (type: New Guinea, not located)
Similar species
Amerila crokeri at first sight resembles A. nigropunctata very much but can easily be distinguished by the white underside of the abdomen while in nigropunctata this is red (see pictures below). The hindwing of crokeri is for the greater part subhyaline while in nigropunctata it is opaque dark brown. The white basal field on the forewing is in both species differently shaped and the forewing costa is more arched in nigropunctata than in crokeri.
Distribution
STATUS: A common species and widely distributed from New Guinea, Northeast Australia to the Solomon Islands. Subspecies bakeri is only distributed in New Guinea.
