Diagnosis

Niesthrea digna is recognized by the slender, vertical, almost C-shaped parameres ( Fig. 8C ) with a large denticle at the base of each; the large, apically widened median lobe; and the broad, apically rounded lateral lobe that is subequal to the height of the parameres in lateral apect. The labium extends to base of abdominal segment IV.

This species is most similar to N. dentata ( Fig. 8A ) in the shape of the parameres and median lobe. Niethrea digna differs in having parameres more C-shaped, smooth through the middle, and with a small denticle apically (vs more triangular, roughened through the middle, and apically rounded in N. dentata ) and the lateral lobe widened and broadly rounded apically in lateral view (vs more slender and narrowly rounded apically in N. dentata ).
