Material.

4 ♀ 4 ♂ (RMNH, ZJUH), "S. China: Fujian, Fuzhou, reared in lab for release, 6.vi.2012, C. v. Achterberg, RMNH’ 12, Psyttalia incisi (Silvestri)". The released reared specimens originate from locally collected stock ( Ji et al. 2004).

Comparative diagnosis.

Psyttalia incisi shares with the very similar Psyttalia makii and Psyttalia fletcheri the long vein r of fore wing (Fig. 28) and the short temple (Fig. 32). Psyttalia incisi can be separated by having vein 2-SR+M of fore wing 3.5-4.0 times as long as wide (Fig. 28; vs about twice as long as wide in Psyttalia makii and Psyttalia fletcheri ) and vein m-cu of fore wing weakly curved or straight (vs strongly curved in Psyttalia makii and Psyttalia fletcheri ).

Distribution.

China (Fujian), India, Malaysia, Thailand, Philippines (Luzon). Introduced in U.S.A. (Hawaii, Florida), Mexico, Fiji, Guam and Australia (New South Wales, Queensland, Western Australia) ( Yu et al. 2012).

Biology.

Parasitoid of Tephritidae : Carpomyia vesuvuana Costa, Bactrocera carambolae Drew & Hancock, Bactrocera correcta (Bezzi), Bactrocera cucurbitae (Coquillet), Bactrocera dorsalis (Hendel), Bactrocera incisa (Walker), Bactrocera latifrons (Hendel), Bactrocera papayae Drew & Hancock, Bactrocera tuberculata (Bezzi), Ceratitis capitata (Wiedemann) and Dacus ciliatus Loew.

Notes.

The series reared in the lab has either the basal half of pterostigma entirely dark brown and similar to its apical half (Fig. 28; males) or its basal half is yellow and contrasting with its dark brown apical half (females). The latter is considered to be typical ( Wharton and Gilstrap 1983) but can be used only for females.
