  1. Calculation of the antenna ratio (AR: complete length of the apical five segments of the flagellum (11–15) divided by the length of the eight basal segments (3-10)) and calculation of the third segment ration (length/width). N1 = number of specimens; N2 = number counted. Means with the same letters are not significant different.
