Identification. This species can be distinguished from the other species of its genus by having the apical infe- rior angles of abdominal segment 10 not produced inward and downward. The inferior margin of the cercus has a plate-like downward expansion just beyond the base, and the upper carinate margin bears a tooth, or strong angulation, between the base and the point where the cercus changes its direction. The first pale antehumeral stripe widens anteriorly and becomes confluent with the pale mesothoraxic “half collar”. The lateral dilatation of abdominal segment 8 is broad and widest mid-length on the segment, and the lateral dilatation of segment 9 is one-third as wide as that of segment 8. The truncated tip of posterior hamule is 2-pointed ( Belle 1988).
