Fig. 7. Niesthrea cassini Göllner-Scheiding male genitalia, redrawned from Göllner-Scheiding (1984) : (A) ventral view. (B) lateral view. Diagnosis Niesthrea dentata is disinguished by the slender vertical parameres ( Fig. 8A ) with a large stout, denticle at the base of each, the large, apically broad median lobe, and the apically slender lateral lobe when viewed laterally. The labium extends to abdominal segment II (on Bolivian specimen; holotype imbedded in glue) . This species is most similar to Niesthrea digna ( Fig. 8A ) in the general shape of the male genitalia. Niesthrea dentata differs in the smooth apically rounded parameres with a roughed area through the middle before the basal spine (versus smooth and concave in N. digna ) and the apically more slender lateral lobe in the lateral aspect (versus broadly round laterally).
