Identity of Lepidiota oblonga Brenske, 1900

Lepidiota oblonga was described from at least one female collected on Thursday Island (10.59°S, 142.22°E) (Brenske 1900) (Figs. 26–28). It was not included in Britton’s (1978) revision but was listed as an Australian species by Houston & Weir (1992) and a lectotype was designated by Allsopp (2020b). Examination of images of the lectotype (Figs. 26–27) show that this taxon is a synonym of Lepidiota rothei Blackburn, 1888, a species known from the tip of Cape York Peninsula south to Giru (19.51°S 147.11°E) and Woodstock (19.60°S, 146.84°E) and from the northern part of the Northern Territory (Britton 1978; Miller & Allsopp 2000).
