Siglophora immaculutea Holloway sp. n.

♂ 10mm. This species is related to bella Butler and hayata Kobes, showing the excavated hindwing distal margin of both and the yellow hindwing base of the latter. The forewing facies is also closer to that of hayata, but the yellow of the basal half is immaculate, lacking the subbasal reddish brown patches of that species; the postmedial yellow mark on the costa is larger, more as in bella. The male genitalia are similar to those of the other two species, the valves with extensive coremata more as in bella, and the field of setae at the valve apex again more as in bella but extending further down the costal side of the valve. The aedeagus is as in bella, but with only two large cornuti on the vesica, associated with a tongue-like sclerite, rather than five spines.
