Xanthopimpla curvimaculata (Cameron, 1899)

Pimpla curvimaculata Cameron, 1899 . Mem. & Proc. Manchester Lit. Phil. Soc. 43 (3): 158. Holotype: ♂, India: Khasi Hills in Assam (OUMNH).

Xanthopimpla cuvimaculata: Krieger (1914)

Xanthopimpla curvimaculata pendleburyi, Townes & Chiu, 1970 . Mem. Amer. Ent. Inst, 14: 264. Holotype: ♀, Malaysia: Kuala Lumpur, Selangor (GPTA). New synonym.

Diagnosis. Face wider than high; median and lateral black marks on mesoscutum jointed posteriorly to black mark in front of scutellum; scutellum strongly convex, lateral flange about 0.8x first flagellomere width; subtegular ridge subtriangular; mid and hind tibiae without stout bristles; area superomedia closed or partly confluent with second lateral area; ovipositor sheath about 0.3x hind tibia.

Distribution. Previously recorded from India, Thailand, and Malaysia ( Yu et al. 2005), this is the first record of X. curvimaculata (Cameron) from Vietnam (Fig. 22).

Remarks. Two subspecies have been recognised: X. curvimaculata curvimaculata from India and Thailand, and X. curvimaculata pendleburyi Townes & Chiu from Malaysia. The latter subspecies differs from the nominate subspecies by the presence of large black spots on the second tergite and by more extensive black marks on the hind leg and metasomal tergites. The specimen recorded in Phu Tho Province (northern Vietnam) agrees well with the nominate subspecies. The specimens collected from Dak Lak and Dong Nai provinces are closer to X. curvimaculata pendleburyi in their more extensive black marks on the tergites, but they have only two small black spots on the second tergite, and a black stripe on the underside of the hind femur (as in the nominate subspecies). In addition, they have large black spots on tergite 3 and a black band on tergite 5. As the differences between the two subspecies have not proved to be stable we here synonymise the two names.
