Wing areas similar to those described for complexus.The cephalic probolae are bordered by long, triangular, acute membranes.  The labial probolae ar bifurcate three-fifths their length, their prongs ending in slender, forward-pointing branches.  Long, triangular, acute membranes fringe the labial probolae.  Strong cutinized points are present at the bases of the labial probolae.  The third and fifth sets of pharyngeal plates are usually inconspicuous. The renette pore lies almost half the distance from the cardiac bulb to the head, a very distinctive feature.  The lips of the small vulva are slightly elevated.  Eggs are two and one-half times as long as the vulva body-diameter and one-third as wide as long.  The phasmids lie far forward at a point almost opposite the anus.
The tail of the male bears seven pairs of papillae.  Spicula arcuate and cephalated.  Accessory piece linear and arcuate.  Males rare, only two being found among about 125 specimens.
Usually found in foothill or mountain soil, rarely from cultivated fields.
