Xanthopimpla nana Schulz, 1906

Xanthopimpla parva Cameron, 1905 . Spolia Zeylanica. 3: 136. Holotype: ♂, Sri Lanka: Peradeniya (BMNH). Junior homonym of Xanthopimpla parva Krieger, 1899 .

Xanthopimpla nana Schulz, 1906 . Spolia Hymenopterologica: 114. Replacement name.

Xanthopimpla nana brevisulcus Wang, 1987 . Acta Ent. Sinica. 30 (3): 332. Holotype: ♀, China: Xishuangbanna Dai Aut, Yunnan (IZCAS). New synonym.

Xanthopimpla aequabilis Krieger, 1914 . Arch. f. Naturgesch. (A) 80 (6): 31. Holotype: ♀, Taiwan: Hengchun (ZMHB).

Xanthopimpla nana aequabilis: Townes & Chiu (1970) . New synonym.

Diagnosis. Hind slope of vertex entirely yellow; propodeum with posterior transverse carina entirely absent; tergites 1, 3, 4, 5, and 7 with two black spots; ovipositor sheath about 0.6–0.8x hind tibia.

Distribution. Townes & Chiu (1970) previously recorded this species from Lam Dong Province (Central Highlands of Vietnam) and Khanh Hoa Province (South Vietnam). Outside Vietnam, this species has been recorded from China, India, Nepal, Sri Lanka, Thailand, Cambodia, Indonesia, the Philippines and Taiwan ( Yu et al. 2005).

Remarks. Five subspecies are currently recognised: X. nana nana from China, India, Nepal, Sri Lanka, Thailand, Cambodia, Indonesia; X. nana aequabilis Krieger from China and Taiwan, X. nana brevisulcus Wang from China, X. nana dama Roman and X. nana stictoprocta Krieger from the Philippines. Specimens collected from North Vietnam belong to subspecies X. nana nana , one female collected in Nghe An seems to belong to subspecies X. nana aequabilis (characterized by two larger lateral black spots on the mesoscutum), and one female from Dong Nai belongs to subspecies X. nana brevisulcus , which differs from other subspecies by the presence of large black stripes on the anterior and posterior faces of the hind femur and a black stripe on the posterior face of the hind tibia. We have found that the differences between the nominate subspecies, X. nana aequabilis and X. nana brevisulcus are minor and unclear. We hereby treat the three names as synonyms.
