Abstract Eight species of the genus Cryptopimpla Taschenberg, 1863 are reported from China, five of them new to science: Cryptopimpla flavipedalis Sheng, sp. n., collected from Ningxia Hui Autonomous Region, and Cryptopimpla rufipedalis Sheng, sp. n. collected from Jilin Province, both from the Palaearctic part of China. Cryptopimpla. carinifacialis Sheng, sp. n., Cryptopimpla flavifacialis Sheng, sp. n.and Cryptopimpla maculifacialis Sheng, sp. n. were collected from Jiangxi Province in the Oriental part of China. A key to the species of Cryptopimpla known from China is provided.


Introduction
According to recent publications (Kuslitzky 2007, 2009, Yu et al. 2005, the genus Cryptopimpla Taschenberg, 1863, belonging to the tribe Atrophini of the subfamily Banchinae (Hymenoptera, Ichneumonidae), comprises 41 species, of which 13 are from the Oriental Region, 20 from the Palaearctic, five from the Nearctic, one is Holarctic, one is Nearctic and Neotropical, and one is from the Ethiopian region. Four species of Cryptopimpla have been reported from China Zheng 2005, Sheng andSun 2009). The status of the genus was elucidated by Townes (1970) and by Chandra and Gupta (1977).
The Oriental species of CryptopimplaTaschenberg were described or redescribed and keyed by Chandra and Gupta (1977). Kuslitzky (2007) provided a key to the banchine genera and species of the Russian Far East. Two species have been described from Japan (Momoi 1970). The European species were catalogued by Aubert (1978). So far, species reported from China were from Henan, Inner Mongolia, Jilin and Taiwan. China is very large and spans two Regions, the Oriental and Palaearctic regions. The genus has not been studied thoroughly in either the Oriental or Palaearctic regions of China.
In the last four years the author has been exploring Jiangxi Province, situated in the northern border of the Oriental part of China, Jilin Province and Ningxia Hui Autonomous Region, both situated at the southern border of the Palaearctic part of China, and has collected large numbers of ichneumonids. New discoveries have been reported (Sheng et al. 2009, and will be reported successively. In this article, five new species of Cryptopimpla are reported, of which one, collected from Jilin Province in the Palaearctic part of China, was previously mistaken as Cryptopimpla helvetica Brauns.

Materials and methods
Specimens were collected using entomological nets in the forests of Quannan, Ji'an and Qianshan Counties, Jiangxi Province; Liupanshan Natural Reserve, Ningxia Hui Autonomous Region; Baihe, Jilin Province (CHINA).
Images of whole bodies were taken using a CANON Power Shot A650 IS. Other images were taken using a Cool SNAP 3CCD attached to a Zeiss Discovery V8 Stereomicroscope and captured with QCapture Pro version 5.1.
The morphological terminology is mostly that of Gauld (1991). Wing vein nomenclature is based on Ross (1936) and the terminology on Mason (1986Mason ( , 1990.
Type specimens are deposited in the Insect Museum, General Station of Forest Pest Management, State Forestry Administration, People's Republic of China.
