Remarks
. The female of this species, with its modification of the anterior abdominal tergites (
Fig. 18
) coupled with the unusual spiculation associated with the posterior margin of the subgenital plate (
Fig. 19
), the small number of marginal metanotal setae, and the large number of sternal setae on IV–VII, is separable from others of this group.
