Latreillia metanesa Williams, 1982

( Figure 2G )

Material examined. M09, Stn. 81, 374m, ♀ ov 3.7× 7.7mm (IEO-CD-MZ09/1810), 16S ( MZ 424916 ) .

Habitat and distribution. IWP, from East Africa ( Somalia, Kenya, Mozambique, Madagascar) to French Polynesia and the Hawaiian Islands at depths between 22 and 806m ( Castro et al. 2003), with records in South China Sea, Taiwan, Philippines, Indonesia, Vanuatu, New Caledonia, and Japan ( Sasaki 2019). In Mozambican waters, the species is recorded between 112 and 403m ( Castro 2013). It inhabits bottoms of sand, foraminifera, coral and rock ( Williams 1982).

Results and remarks. Only one specimen was studied, being an ovigerous female, collected in March 2009 (M09) at 374m depth. This specimen agrees well with the descriptions and figures in Castro et al. (2003). The specimen was collected badly damage.

Colouration observed. The carapace was crossed longitudinally by orange and beige lines, which curve at the posterior edge of the carapace. The ambulatory legs, as well as the chelipeds, bear orange and beige transverse lines.

DNA barcodes. There are not sequences available for this species on any public database. Thus, the 16S sequence is the first one for this species and is close (98.49%), at intrageneric distance, to one sequence of Latreillia valida ( MK 204361 ).
