Revised diagnosis

Diagnosis by Petryashov & Frutos (2017) based on both sexes, here revised for inclusion of S. doryphorus sp. nov. Eye rudiments separate, without stalks, positioned laterally, not connected by membranous integument, each reduced to roughly triangular pad with tooth-like, non-sensory distal projection extending beyond median segment of antennular trunk; visual elements strongly reduced, no ocular papilla. Antennular trunk 3-segmented; weakly oblique articulation between median and terminal segment. Antennal scale with bare lateral margin and setose mesial margin. Antennal peduncle with three segments lined in a single plane and separated by transverse articulations. Clypeus with long, unpaired anterior process. Labrum normal, without spiniform rostral process. Thoracomeres and pleomeres normal. Thoracic endopod 2 not prehensile. Female pleopods representing setose rods with residual differentiation of pseudobranchial lobe. Male pleopods biramous, with well-developed sympod and multi-segmented exopod. Endopod 1 short, unsegmented; endopods 2–5 long, multi-segmented; all endopods with small pseudobranchial lobe. Uropods undivided, setose. Telson elongate linguiform with lateral constriction, minimum width at about ⅓ of length from terminus. Telson mid-terminally with small rounded indentation or with distinct, proximally rounded cleft, in any case lined with small laminae and flanked by large spines, no setae; terminal spines with size not increasing in continuous series laterally.
