The only other known specimens are listed below and include females from South Australia . The antennae and pelta are similar to those of cotteri , but the head is different in having the maxillary stylets broadly crossing each other ( Fig. 11 ). Females have a single pair of long, sigmoid wing-retaining setae on tergites II – V , but males on II – VII . Tergites IV – VII of females have double transverse rows of short stout setae ( Fig. 32 ), and similar setae are on the basal half of the tube and the posterolateral angles of the ninth tergite. The mesopresternum is narrowed medially where the anterior margin of the mesoeusternum projects forwards .
