Parathranites granosus Crosnier, 2002

( Figure 13F )

Material examined. M08, Stn. 25, 265m, ♀ 20.9× 15.2mm (IEO-CD-MZ08/1785), 16S ( MZ 424966 ), COI ( MZ 434811 ) .

Habitat and distribution. Philippines, Indonesia, Admiralty Islands, at a depth range of 107–274m ( Crosnier 2002).

Results and remarks. Only one female specimen was collected in M08 at 265m depth. This specimen agrees well with the descriptions and figures in Crosnier (2002). This is the first record of P. granosus off Mozambique.

Colouration observed. No pictures are available.

DNA barcodes. There is only a short (400 bp) and incomplete 16S sequence for this genus in Genbank belonging to P. orientalis (Miers) deposited by Tsang et al. (2014). This corresponds probably to the version of the sequence after alignment and removal of hypervariable positions, for example after application of GBlocks, as mentioned above for other species in the same work. Although a robust comparison is not possible without the complete 16S sequence, the 11 mutations found in the 400 bp in relation to the 511 bp of the 16S sequence of the female IEO-CD-MZ08/1785 suggest a distance that fits well at interspecific level. There are not COI sequences of this species on any public database, but the BOLD search shows 88.61 to 95.16% of similarity with other species of this genus as P. tuberosus Crosnier , P. intermedius Crosnier , and P. orientalis .
