Additions to original description. Clypeal chaetae 8, all ciliate and arranged in three rows; the middle one much smaller ( Fig. 48 ). Lateral process of labial palp exceeding the papilla. Post-labial chaetae H1 and H4 ciliate; X3 often absent. Cephalic groove with 8 chaetae, the first and the third ones smooth and others ciliate ( Fig. 51 ). Trochanteral organ with 11–15 spiny chaetae, 10–12 in arms and 1–3 between arms ( Fig. 49 ). Ventral tube anteriorly with 7+7 ciliate chaetae ( Fig. 46 , same as S. gei ); posteriorly with 10 smooth chaetae; each lateral flap with 8 smooth chaetae ( Fig. 50 ). S-chaetotaxic formula 2, 2/1, 2, 2, –, 3 sens, 1, 0/1, 0, 0 ms.
