Figure 4.Female genitalia. A Lateral view of the dome-shaped genital area (compare also to Fig. 3A) (MACN-Ar 30667) B Sagital section through genital area obtained by micro-CT (MACN-Ar 30667) C Posterior view of genital area (MACN-Ar 30667). Spermathecae in anterior (D) and ventral view (E) (ZIMG II/28128).

Figure 5.Right male palp of Progradungula otwayensis (ZIMG II/28127). A Prolateral view; the arrow marks the section plane of Fig. 5B B Section of the volume rendered male palp C Surface model of the spermophor superimposed on the volume rendering of the male palp (prolateral, ventral and retrolateral views). The cymbium, subtegulum and tegulum are partly removed in the prolateral view to show tendons, muscles and hematodochae. The arrow points to the opening of the embolus. Abbreviation: Cb cymbium; E embolus; m29 muscle 29; m30 muscle 30; mA median apophysis; mH median hematodocha; PE process of embolus; S spermophor; St subtegulum; Te tegulum; tm29 tendon of muscle 29; tm30 tendon of muscle 30.
