Barcode. Not available.

Remarks. The male terminalia of Eutropha noctilux are unknown.

Distribution. Borneo, Java, Indonesia, Malaysia, Philippines, Singapore *, Sumba, Pacific Islands, New Guinea, Australia.

In addition to the aforementioned taxa, we found undetermined specimens of the genera Chlorops ( Fig. 5B ), Elliponeura ( Fig. 5C ), Cerais ( Fig. 5D ), and Thressa ( Fig. 5E ) occurring in Singapore. The genera Cerais and Thressa are being recorded for the first time in Singapore and the genus Elliponeura is being recorded for the first time in the Oriental region. Unfortunately, the mOTUs assigned to these genera are singletons and no males were available to reliably assign these taxa to species.
