Collected during March–April, July and November (label data). Notes. Originally described as Dysis excellens , it was transferred to Oenopia and redescribed by Poorani & Booth (2005) . It is externally similar to Oenopia guttata (Blackburn, 1892) , a species found in Australia and New Guinea . Kovář (2007) listed ‘ O. excelens’ as a new combination and wrongly synonymized O. guttata with ‘ O. excelens’.
