Remarks

This species is distinct from all the others known in this group based on molecular data (minimum 16S p-distance: 14%), but the only specimen available is too damaged to provide a sufficient morphological description. Rostral formula: 19 (10)/3, rostrum 0.38 times as long as carapace length, egg size 0.40–0.43 mm × 0.23–0.26 mm ( Figure 7 View Figure 7 ).
