Austrosimulium ungulatum Tonnoir 1925 .

Of the nine specimens identified as A. ungulatum , one (#5) lacks the head ( Table 2 ). Of the remainder, four (#1-4) have the left side of the head fully female, two (#6, 7) male and two (#8, 9) partially male. Three (#1, 2, 8) have fully expressed male eyes on the right (Fig. 12), another (#7) is partially male on that side. The two specimens (#7, 8) having male eyes on both sides are dichoptic; however, both have only partially expressed male eyes on one side or the other. Two (#3, 4) have fully female heads and three specimens (#1, 7, 8) have both male and female antennae (e.g., Fig 12). All nine each have a fully expressed, domed, male thorax. Seven (#1-4, 7-9) have either male or female claws on the legs. Two (#5, 6) have only male claws. Specimen #1 has, on one leg, both a male and a female claw (Fig. 13)! All specimens express some male genitalia, but only three (#6, 7, 9) are fully so, though #7 has a distorted 8th sternite, and #9 a deformed gonostylus. The remaining specimens show various mixtures of male and female genitalia, ranging from two (#5, 8) with essentially bilateral gynandromorphy (Fig. 14), to two (#1, 4) with essentially un-interpretable mixtures of genitalic structures.
