Appendages. Trochanteral organ with 13 smooth spine-like chaetae ( Figure 16H View Fig ). Collophore anterior side with 2 subapical mac of equal length, 1 smaller median mes, and 4 proximal smooth mic; posterior side with 1 apical and 1 subapical smooth chaetae; lateral flap formula 4(s), 4(m), 5(i) smooth chaetae, 2 inferior larger ( Figures 18 View Fig F- G). Manubrial plate with 3 chaetae ( Figure 19C View Fig ). Mucro with 3–4 teeth (d1, ap, v1-2), v2 teeth present or absent ( Figure 19E View Fig ).
