Basal chaeta on maxillary outer lobe thick and blunt; sublobal plate with three smooth chaetae-like processes (Figs 20 View Figures 20–25 , 21 View Figures 20–25 ). Lateral process (l. p.) of labial palp E differentiated, as thick as normal chaeta, with tip not reaching apex of papilla E (Figs 22 View Figures 20–25 , 23 View Figures 20–25 ).
