Analysis of variance of morphological characters useful to discriminate A. gossypii, A. monardae, and A. sedi. The gray line represents the median. The gray diamond represents the means and standard deviation. A 95% level indicates a significant difference. A distance from the base of antennal segment III to the first secondary sensorium (DBIII) between A. gossypii and A. monardae B ratio of length of processus terminalis (PT) to the base of last antennal segment B between A. gossypii and A. sedi C ratio of length of siphunculi (SIPH) to the length of cauda (CA) between A. gossypii and A. sedi.
