Batch size: 51.5 ± 10.1 (n = 13)

Realised fecundity: 150–280

Incubation time (days): 10.3 ± 0.5

Batch configuration and attachment: Attached to substrate by posterior pole, laid upright in large groups in neat rows with every row off­set (Figs 464–466).

Colour: Olive green with white mesh­like reticulation, shiny, becoming grey on maturity (Figs 464 & 466).

Size (mm): (n=19) L =0.78 ± 0.01, W=0.57 ± 0.01, T=0.57 ± 0.01

Width/length: 0.73

No. of females: 3

Aeropylar opening size (m) (n=6): L=2.4 ± 0.08, W=2.3 ± 0.08

Relative aeropylar opening size: 2.9

Micropyles: Distinct (Figs 464–468)

Shape: Moderately broad, bluntly ovoid, anterior pole markedly truncated, much wider than posterior, polar profile sub­circular, dorso­ventrally flattened (Figs 464–467, 469–470).

Characteristics: Egg marked all over by hexagonal cells with concave floors (Figs 465, 467, 469–471), cells only faintly discernible on posterior half of egg (Figs 465, 469, 470 & 472). Moderately wide, elevated cell walls only reticulated on anterior half of egg. Reticulated cell walls double­ridged (Figs 473 & 474). Aeropyles moderately elevated, domed, openings moderately large present in area adjacent to anterior pole (Fig. 474). Chorion deeply ridged, folded on anterior half of egg (Fig. 473 & 474), smoother on posterior half (Fig. 472).
