Habitat and distribution. Tanaoa pustulosus is distributed along the IP ( Fiji, New Caledonia, New Zealand, Japan, Taiwan, Indonesia, Philippines, Andaman Sea, Seychelles, Comoro Islands, Madagascar, Reunion, Mozambique Channel and East Africa), at 85–977m depth ( Galil 2003c).

Results and remarks. Our specimens agree well with the descriptions and illustrations included in the work of Galil (2003c), in which the genus Randallia Stimpson was redefined, and the new genus Tanaoa erected. Thirteen specimens of T. pustulosus , collected in the three surveys (M07, M08 and M09), at depths between 190 and 658m, were examined. These specimens are the first records of T. pustulosus in Mozambican waters. After our surveys, some specimens were collected in the MB-exp in 2009 (Chan & Ng, pers. comm. to Emmerson, 2016c).

Colouration observed. The dorsal surface of the carapace was orange, with red tubercles on the gastric area and whitish tubercles on the cardiac and intestinal areas. Legs were pale pinkish-white.

DNA barcodes. There are not 16S sequences available for this species in Genbank, and thus, the four sequences (two haplotypes, differing in one position) of the specimens from MZ08 and MZ09 are the first ones for this species. There is only one COI sequence deposited in BOLD ( MDECA231-10 ), corresponding to a specimen of T. pustulosus collected in Mozambique, by the MB-exp in 2009 (date collection: 2009-04-09) deposited at the MNHN ( MNHN-IU 200812672 ). The COI sequences of three specimens from MZ08 and MZ09 represent three different haplotypes (varying in one-two positions), fitting 99% with the BOLD sequence (varying in three to five positions).
