Fig. 5 in A new deep-water Tethya (Porifera, Tethyida, Tethyidae) from the Great Australian Bight and an updated Tethyida phylogeny
Fig. 5 (opposite page). Tethyida COI and 28S maximum-likelihood (RaxML) trees. ML bootstrap supports (1000 bootstrap replicates)> 70 are indicated. After the species name, locality of the specimen is given (when known), followed by the GenBank accession number(s). For 28S, we also indicated the 28S region that was sequenced as well as the first author + date of the publication where the sequence first appeared. Type species of genera are in red boxes while Tethya irisae sp. nov. appears in red.

Fig. 1 in A new deep-water Tethya (Porifera, Tethyida, Tethyidae) from the Great Australian Bight and an updated Tethyida phylogeny
Fig. 1. Sites where Tethya irisae sp. nov. was collected in the Great Australian Bight, including sites that were sampled where the sponge was not found. All specimens of Tethya irisae sp. nov. were collected along the 1000 m contour. Light shaded polygons show the Australian Commonwealth Marine Reserves. The darker polygon strip is the GAB Marine Park Benthic Protection Zone. The 200 m contour is the edge of the continental shelf. Abbreviations: GABDMP = Great Australian Bight Deepwater Marine Program (MNF 2015); GABRP = Great Australian Bight Research Project (Williams et al. 2018). Cruise SS2010_T02 (Currie & Sorokin 2011).
