Sabatieria multipora sp. nov.

( Figures 6 – 9 , Table 2 )

Type material. Holotype male in inventory slide no. MBSMCOIA-M10D-2-2-5-1. Paratypes: four males in inventory slide no. MBSMCOIA-M10D-1-2-5-1, MBSMCOIA-M10D-1-5-10-1, and MBSMCOIA-M10D-1-5-10-2; two females in inventory slide no. MBSMCOIA- M10D-1-2-5-1, and MBSMCOIA-M10D-3-2-5-4.

Type locality and habitat. Holotype collected in the Prydz Bay , 68.2833°S, 75.5827°E; depth 578 m; 31 December 2020; total organic carbon 1.37%; sand, 7.87%; clay, 16.77%; silt 75.37%; mean particle diameter 6.2 μm . Paratypes, same collecting data as for holotype.

Etymology. The species epithet is named after the coarse, irregularly-spaced punctations that seem as numerous pores distributted over most part of body cuticle, visible with scanning electron microscopy.
