Melvin, 26 July 2016, coral rubble, ~3m. Distribution. Fiji (type locality); Cook Island; Chesterfield and Melish Reefs, Moorea, Coral Sea; Lord Howe I, Tasman Sea; Papua New Guinea; Northern Territory, Queensland, Australia; Pulau Dayang, Pulau Tinggi, Malaysia; Pulau Tioman, Malaysia; Pulau Langkawi, Malaysia. Molecular data. A 631 base pairs of COI sequence (GenBank: MF680512) was acquired from one individual of E. collaris . No insertion or deletion in the sequence alignment. Remarks. Expanathura collaris is a widespread species dwelling in coral reef rubble especially within the Southeastern Pacific and Australian region (Kensley 1979a; Negoescu 1999 ; Negoescu and Brandt 2001; Poore and Lew Ton 2002 ). This is the first record of E. collaris from the Southeast Asia region.
