Tergite I with very slight medioposterior convexity, II with wide rounded convexity, III with moderate rounded convexity, IV –VI with slight median compression, and VII –VIII normal. Tergal setae: I, 13; II –V, 14–15; VI, 13; VII, 11; VIII, 8. Postspiracular setae shortest on V, moderately long on I, III, and VI –VIII, and very long on II and IV.

Remarks. The female of this species, with its modification of the anterior abdominal tergites ( Fig. 18View FIGURES 18 – 21. 18 – 19) coupled with the unusual spiculation associated with the posterior margin of the subgenital plate ( Fig. 19View FIGURES 18 – 21. 18 – 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.
