Funicle segments fl5 and fl7 with 2 mps ( Fig. 192 View FIGURES 192 – 194 ). Antennal measurements ( holotype), length/width (ratios of funicle segments): scape 309/63, pedicel 69/45, fl 1 37/28 (1.32), fl 2 26/28 (0.93), fl 3 30/39 (0.77), fl 4 26/28 (0.93), fl 5 40/30 (1.33), fl 6 28/31 (0.90), fl7 35/35 (1.0), fl 8 29/46 (0.63), clava 258/68.
