was based only on males. However, as already noted by Reichert (1994), the illustrated holotype (Amato, 1986: fig. 8) is a female. The description also indicates that contact organs were absent in all specimens of the type series, suggesting that it comprises only females. This may be confirmed through examination of the type series, which was not available during the present study.
