Remarks. The species C. smilodonta seems to have an absent accessory flagellum on Antenna 1. However, we did not add this information to create a new amended diagnosis because this structure is very fragile and could have been lost during the material manipulation. Otherwise, we decided to add the absence of accessory flagellum as a valid character on the identification key to world species of Cymadusa .
