Remarks

• Structure: Scales usually separate, sometimes coalescing, round, seen from above, 4 mm. long, convex, but flattened dorsally, so that they are not half as high as broad; surface thrown more or less into concrete folds; colour bright orange; median dorsal area ferruginous, with radiating ridges and the usual orifices, the minutely transversely ribbed larval exuviae in the middle. Young up to about 2 mm. long, orange-ferruginous, with rather obscure radiating ridges (Cockerell, 1903c). Resinous test of adult female (fig. 1) circular, somewhat flattened dorsally: the larval pellicle forming a crenulated ridge in the centre of the dorsal area: anal orifice circular or broadly oval, its posterior rim raised into a prominent tooth-like point: respiratory orifices small, very slightly prominent, situated one on each side of and close to the larval pellicle: sides more or less distinctly broadly radially fluted. Colour bright fulvous to castaneous, the larval pellicle reddish; semitranslucent. Diameter 25 mm (Green, 1913).
• Biology: Found on bark of branch (Cockerell, 1903c).
• Economic Importance: Female wasps are known to adjust their offspring sex ratios depending on host size, with a female biased sex ratio on larger hosts. A significant relationship was found between the size of female T. aurantiaca and the number of emerging Tachardiaephagus somervillei. Rearing of T. aurantiaca on larger size host plants under optimum conditions in the field is likely to produce larger females at a shorter development time with more crawlers produced per female. Therefore, Ong, et al. (2014) suggested that this parasitoid could have important implications on the biological control of T. aurantiaca.
