Remarks. This species is easily separated from others of this group by the unique shape of the anterior female abdominal tergites ( Fig. 15View FIGURES 9 – 17. 9 – 10) and the posteriorly narrowed male genital sac sclerite ( Fig. 16View FIGURES 9 – 17. 9 – 10). The number of tergal setae and dimensions further support this separation.
