Amended diagnosis

Males of Neischnocolus cisnerosi resemble those of N. armihuarensis and N. caxiuana by having an embolus straight perpendicular (dorsal curvature) to palpal organ axis and presence of a median dorsal granular area. Nevertheless, males of N. cisnerosi differ from those of N. armihuarensis by having two developed retrolateral palpal tibial apophyses, median dorsal granular area composed of rounded spicules extending only over dorsal surface of bulb, PS and PI keels developed and comparatively longer, distal portion of embolus dilated, and a prolateral accessory inferior keel extremely weakly developed (one developed retrolateral palpal tibial apophysis, median dorsal granular area composed of spiky spicules extending over prolatero-dorsal and retrolateral surfaces of bulb, PS and PI keels weakly developed and comparatively shorter, distal portion of embolus not dilated, and prolateral accessory inferior keel absent in N. armihuarensis ; Kaderka 2014: figs 4–5, 7–10); from N. caxiuana by having median dorsal granular area composed of rounded spicules extending only over dorsal surface of bulb, PS and PI keels well developed and comparatively longer, distal portion of embolus dilated, and prolateral accessory inferior keel extremely weakly developed (median dorsal granular area composed of spiky spicules extending over dorso-retrolateral surfaces of bulb, PS and PI keels developed and comparatively longer, distal portion of embolus dilated, and prolateral accessory inferior keel absent in N. caxiuana ; Fig. 4).
