Schematic diagrams of hypothesised oviposition posture. 130 hypothesised function of lamina on ventrite 4 and horns surrounding genital orifice on ventrite 5, which force apart dense foliage of cushion plants to allow oviposition in peaty layer underneath 131 hypothesised function of recurved margin of ventrite 4 which allows maximum flexion of ventrite 5, enabling oviposition under the side of cushions between the plant and the surrounding substrate. Abbreviations: V4–ventrite 4; V5–ventrite 5. Figures not drawn to scale.
