Colour: Pale green, becoming mottled reddish then uniformly purplish to dark brown, transparent greyish­brown before eclosion. Size (mm): (n=30) L= 1.04 ± 0.01, W=0.82 ± 0.01, T=0.60 ± 0.01 Width/length: 0.79 No. of females: 3 Aeropylar opening size (m) (n=5): L=2.82 ± 0.26 Relative aeropylar opening size: 2.8 Micropyles : Indistinct (Figs 318 & 319) No. of openings: 6 No. of cells in rosette: 9 No. of rows of cells in micropylar area: 4 Shape: Moderately broad, bluntly ovoid, posterior pole sub­acute, wide; polar profile circular; wedge­shaped in profile (Figs 317, 318, 320 & 321); anterior pole truncated slightly angled to horizontal axis (Figs 317, 320 & 321). Characteristics : Egg marked on all surfaces by slightly convex hexagonal cells (Figs 317, 320–322). Cell walls narrow, recessed (Fig. 319); on lateral side barely distinguishable (Fig. 322); micropylar cell walls narrow, slightly elevated (Fig. 319); primary and secondary cell walls recessed; cells in middle of top of egg slightly concave (Figs 317 & 320). Aeropyles irregularly shaped, unelevated, openings moderately small, inconspicuous (Fig. 322), present on all surfaces apart from middle of top of cell (Fig. 320). Micropyles slightly off­centred. Anterior pole circumscribed by raised rim (Fig. 318). Chorion rough, pitted, wrinkled (Fig. 322).
