Introduction
The tribe Cotesiini (Braconidae, Microgastrinae) was established by Mason (1981) with most members parasitizing on Macrolepidoptera. A few species of this tribe have been used in biological control of lepidopteran pests. The genera Deuterixys and Wilkinsonellus are two small genera of this tribe, and both characterized by a longitudinal median groove at least at basal half of the first tergite and without an areolet of fore wing.
The genus Deuterixys proposed by Mason (1981) includes four Old World species of Nixon’s (1965, 1976) carbonarius group of Apanteles Förster. This genus includes 14 described species widespread in the world except in the Afrotropical region, of which seven occur in the Old World and seven in the New World (Nixon 1965; Tobias 1971, 1976; Papp 1983b, 1990; Whitfield 1985; Austin and Dangerfield 1992; Marczak and Buszko 1994; Yu et al. 2005). Most species of the known hosts of this genus are leaf miners, including the genera Bucculatrix and Leucoptera of the family Lyonetiidae and Stigmella of the family Nepticulidae (Lyle 1925; Wilkinson 1936, 1940; Telenga 1955; Nixon 1965; Tobias 1976, 1986; Papp 1983a; Whitfield 1985; Marczak and Buszko 1994; Gates et al. 2002), which may cause damage in forests. Therefore, species of Deuterixys may play an important role in controlling those forest pests. Recently two new species of this genus are found in China among specimens of Parasitic Hymenoptera Collection of Zhejiang University (ZJUH) and described in this paper. They represent the first record of the genus Deuterixys Mason for China.
The genus Wilkinsonellus was proposed by Mason (1981) to include four Old World species of Nixon’s (1965) henicopus and daira group of Apanteles Förster, including five described species occurring in Oriental region, four in the Australasian region and one in the Afrotropical region (De Saeger 1944; Nixon 1965; Austin and Dangerfield 1992; Chou 1999; Long and van Achterberg 2003; Chen and Song 2004; Ahmad et al. 2005; Yu et al. 2005). One species, Wilkinsonellus iphitus (Nixon 1965) was previously recorded from Hainan and Taiwan of China (Chou 1999; Chen and Song 2004). Here we report another species of this genus, Wilkinsonellus paramplus Long & van Achterberg, 2003, from China for the first time.
Material and methods
Specimens studied are deposited in the Parasitic Hymenoptera Collection of Zhejiang University, Hangzhou, China (ZJUH). Descriptions and measurements were made under a stereomicroscope (Zeiss Stemi 2000-C). All figures were made by a camera (Q-Imaging, Micropublisher, 3.3 RTV) attached to a stereomicroscope (Leica MZ APO, Germany) and Auto-Montage Pro version 5.0 software.
Terminology and measurement follows Nixon (1965) and Mason (1981), vein terminology follows the modified Comstock-Needham system (van Achterberg 1979). Abbreviations used in this paper are as follows: POL = postocellar line, OOL = ocular-ocellar line, OD = ccellar diameter; TI = the first tergite of metasoma, TII = the second tergite of metasoma, TIII = the third tergite of metasoma; L = length, W = width.

Materials examined.
Holotype: ♀, Mt. Qingliangfeng (118°52'E, 30°04'N; 119°12'E, 30°31'N), Linan, Zhejiang, 2005. VIII. 9, leg. Min Shi, No. 200607234. Paratype: 1♀, Mt. Yinggeling (109°31'E, N19°04'N), Hain0061n, 2007. V. 24–25, leg. Jingxian Liu, No. 200702641.
Etymology.
The specific name “bifossalis” derives from the Latin prefixion “bi-” and adjective “fossalis”, referring to both distinct lateral grooves enclosing a median field of the second tergite.
Distribution.
China (Zhejiang, Hainan).
Remark.
This species is similar to the Palaearctic species Deuterixys rimulosa (Niezabitowski, 1910), but can be distinguished from the latter by having TI not transverse (more transverse in Deuterixys rimulosa), and vein 1-R1 of fore wing longer than pterostigma (the latter subequal to or slightly shorter). It also differs from the other Oriental species Deuterixys patro (Nixon, 1965) by TII and TIII not forming a carapace and having exposed the following tergites (the latter TII and TIII enlarged to form a carapace and following tergites retracted).

Etymology.
The specific name “curticalcar” derives from the Latin prefixion “curti-” and noun “calcar”, referring to the short hind tibial spurs.
Distribution.
China (Jiangxi, Henan, Hunan, Guangdong, Guizhou, Yunnan, Ningxia).
Remark.
This species is similar to the Palaearctic species Deuterixys carbonaria (Wesmael, 1837), but can be distinguished from the latter by having TI long, more than 1.5 times as long as wide (TI subrectangular, 1.2–1.3 times as long as wide in Deuterixys carbonaria); TII much longer than TIII (TII almost as long as TIII); and inner hind tibial spurs shorter than 0.5 times hind basitarsus (much more than 0.5 times hind basitarsus).
