Diagnosis

This species is distinguished by the vertically quadrate paramere ( Fig. 10A ) with a large denticle at the base, the large broad, bilobed median lobe contricted at the base, and the relatively slender, pointed lateral lobes in lateral aspect. The labium extends to the base of abdominal segment III or slightly beyond.

Niesthrea pictipes is most similar to N. casinii and N. truncata sp. nov. in the general shape of the parameres. It can be separated from N. casinii ( Fig. 7A ) by the more quadrate parameres with a large projection at the base of each (vs broader and more rounded on outer margin) and the broadly rounded, bilobed median lobe (vs distinctly conical); and from N. truncata sp. nov. ( Fig. 11A ), by the quadrate parameres (vs more broadly rounded) and the high, broad median lobe with large rounded lateral processes (vs short, narrow, and quadrate).
