All the male specimens studied here of this species possess 12 separate flagellomeres, with the first to fifth (rarely sixth) flagellomeres bearing small translucent sensilla; Möhn (1960) described his specimens to have 11–12 flagellomeres, the two apical flagellomeres merged into one, and all flagellomeres bearing small translucent sensilla (“Sinneskolben”).
