The antennal distal antennomere apex is occasionally not appendix like, but simply narrowing to a sharp point. In juvenile females the ear-like structures of the 8th and 9th lobes are undeveloped.The lobe on the 10th thoracic segment may be more rounded and symmetrical than asymmetrical and triangular.
