Batch size: 6–15; (n = 3) Realised fecundity: 27 Incubation time (days): 8 Batch configuration and attachment : Firmly attached, singly (Fig. 844). Colour: Pale yellow becoming dark yellow with faint orange streaks (Fig. 844), then transparent grey on maturity. Size (mm) (n=9): L = 1.00 ± 0.01, W = 0.78 ± 0.00, T = 0.58 ± 0.01. Width/length: 0.78 No. of females: 2 Aeropylar opening size (m) (n=1) : L = 1.76. Relative aeropylar opening size: 2.0 Micropyles : Indistinct (Figs 845 & 846) No. of openings: 1 No. of cells in rosette: 6 No. of rows of cells in micropylar area: 7 Shape: Moderately broad, bluntly ovoid, anterior pole truncated, posterior pole subpointed, compressed dorso­ventrally (Figs 844, 845 & 847). Characteristics : Egg faintly marked on all surfaces by convex, hexagonal cells with moderately broad elevated walls (Figs 844, 845, 847 & 848); except cells on middle of top of wide side concave, rounded (Fig. 848). Aeropyles very inconspicuous, unelevated, openings small, distributed around rim of egg only. Micropylar cell walls overlaid by a narrow shallow reticulum (Fig. 846). Chorion generally smooth, with shallow undulations, each cell generally with six large pits at junctions (Fig. 849).
