Abstract

MicroCT scan of lectotype specimen AM J. 30960 of Tripneustes australiae (Tenison-Woods, 1878) (Echinodermata: Echinoidea: Toxopneustidae) in the Australian Museum (Sydney) collection. Originally described as Evechinus australiae and subsequently registered together with two other syntype specimens under the number AM J. 1099. Lot subsequently split into three separate inventory numbers, each containing the remains of a single individual (AMJ. 30960, J. 30961, and J. 1099). Lectotype designation and redescription by McLaren et al. (2023).
