(type species)

Oviposition

9♀ Code nos.: G207, G213, G214, G216, G220, G237, G242, G262, G367.

Period of oviposition: 23 Apr.–28 May

Batch size: 23.6 ± 4.6 (n = 14)

Mean realised fecundity: 36.8 ± 10.3

Incubation time (days): 19–37 (on moistening)

Batch configuration and attachment: Attached, singly or in small groups (Fig. 211).

Colour: Pale olive green, becoming olive green mottled with pale brown to greyishbrown (Fig. 211).

Size (mm): (n= 5) L=0.67 ± 0.00, W=0.60 ± 0.00, T=0.59 ± 0.01

Width/length: 0.90

No. of females: 3

Aeropylar opening size (m) (n=7): L=1.5 ± 0.09, W=1.4 ± 0.11

Relative aeropylar opening size: 2.3

Micropyles: Distinct (Figs 212 & 213)

No. of openings: 5

No. of cells in rosette: 10

No. of rows of cells in micropylar area: 5

Shape: Broad, bluntly ovoid, anterior pole truncated, wider than posterior pole, polar profile circular, dorso­ventrally flattened (Figs 211, 214 & 215).

Characteristics: Egg marked on all surfaces with hexagonal cells with flat to slightly convex floors (Figs 212, 214–218). Cell walls narrow, slightly elevated (Figs 216–218). Aeropyles only present on poles, slightly elevated, domed, openings small (Figs 212, 217

& 218). Chorion appears rough due to dense, shallow, irregular ridges (Figs 217–219).
