The genus Brulleia Szépligeti (Hymenoptera, Braconidae, Helconinae) from China, with descriptions of four new species

Abstract The species of the genus Brulleia Szépligeti, 1904 (Hymenoptera, Braconidae, Helconinae) from China are revised. Four new species, namely Brulleia fanjingensis YanandChen, sp. n., Brulleia longipalpis YanandChen, sp. n., Brulleia noncarinata YanandChen, sp. n. andBrulleia punctata Yan andChen, sp. n. are described and illustrated. A key to the Chinese species of the genus Brulleia is included.

Ten species were already recorded from China (Chen et al. 1993;Chen et al. 1998Chen et al. , 2001Chou and Hsu 1998). In the present paper additional four new species of this genus are described and illustrated from Guizhou, Tibet and Hebei, the western and northern parts of China: B. fanjingensis Yan and Chen, sp. n., B. longipalpis Yan and Chen, sp. n., B. noncarinata Yan and Chen, sp. n., and B. punctata Yan and Chen sp. n. They are described and illustrated in detail, and a key to all Chinese species of Brulleia is updated.

Material and methods
The terminology and measurements used follow van Achterberg (1983van Achterberg ( , 1988van Achterberg ( , 1993 and Chen et al. (1993). Additional sources for the description of sculpture and setation are Belokobylskij (1998). The following abbreviations are used for morphology: POL -postocellar line; OOL -ocular-ocellar line; OD -maximum diameter of lateral ocellus. Type specimens and other materials are deposited in the Parasitic Hymenoptera Collection of Zhejiang University, Hangzhou, China (ZJUH) and Shanghai Entomological Museum, Chinese Academy of Sciences, Shanghai, China (SEMS), respectively.
Descriptions and measurements were made under a stereomicroscope (Zeiss Stemi SV 6). All figures were made with a Leica DFC425 Camera attached to a stereomicroscope (Leica M205 A, Germany) and Leica Application Suite version 3.60 software.
Distribution. China (Guizhou). Etymology. It is named after the type locality of the species, Fanjing Mountain in Guizhou Province of China. Description. Body length (excluding ovipositor sheath) 16 mm. Fore wing length 13.5 mm.
Legs. Length of hind femur, tibia and basitarsus 6.0, 13.3 and 10.0 times their width, respectively. Hind tibia 1.8 times as long as hind femur.
Metasoma. First tergite reticulate-punctate, medio-posteriorly smooth, dorsal carinae distinct in basal 0.3. Length of first tergite twice its apical width. Ovipositor sheath 3.4 times as long as metasoma, 3.7 times as long as hind tibia, 5.0 times as long as mesosoma, and 2.3 times as long as fore wing.
Colour. Body black. Antenna dark brown but 10th-17th flagellomeres yellow. Palpi yellow. Tegulae, basal of mandible and labium reddish brown. Legs yellow to reddish yellow but coxae reddish brown, hind tarsus whitish yellow. Second tergite reddish yellow at two-thirds basolaterally. Ovipositor sheath dark brown. Wing membrane fumose with veins dark brown.
Male. Unknown. Diagnosis. This new species is similar to B. obereae Chen and van Achterberg, but differs in having the maxillary palp longer, its length 1.1 times height of head (in latter 0.5 times); temple densely punctate (in latter sparsely and finely punctulate dorsally, and rugose ventrally) and first tergite mainly reticulate-punctate, but medioposteriorly smooth (in latter basally transversely, medially irregularly and apically more or less longitudinally rugose).
Distribution. China (Tibet). Etymology. It is named after its very long maxillary palp. Legs. Length of hind femur, tibia and basitarsus 5.8, 12.8 and 11 times their width, respectively. Hind tibia 1.7 times as long as hind femur.
Colour. Body black. Malar space apically, base of mandible and labium dark red. Palps yellowish brown. Tegulae dark brown. Coxae, hind femur and apical one-fourth of hind tibia dark reddish brown; trochanters and tarsus whitish yellow; fore and middle femora, tibiae and basal three-fourthes of hind tibia yellowish brown. First-third metasomal sternites yellowish brown. Pterostigma and most of veins dark brown, wing membrane fumose.
Male. Unknown. Diagnosis. This new species is similar to B. flavibasalis He and Chen, but differs in having the clypeus rugose-punctate, ventrally with obscure transverse striae, its apical margin convex and with median notch (in latter finely rugose, its apical margin slightly concave and without median notch); the dorsal carinae of first tergite absent (in latter present in basal half) and the most part of the body black (in latter brownish yellow).
Legs. Length of hind femur, tibia and basitarsus 6.4, 13.7 and 10.7 times their width, respectively. Hind tibia 1.8 times as long as hind femur. Metasoma. First tergite robust and widened posteriorly, densely rugose, smooth apically, dorsal carinae obscure. Length of first tergite 1.8 times its apical width. Second and following tergites smooth and shinny. Ovipositor sheath twice as long as metasoma, 2.5 times as long as hind tibia, 2.7 times as long as mesosoma, and 1.3 times as long as fore wing.
Male. Unknown. Diagnosis. This new species is similar to B. flavibasalis He and Chen, but differs in having the frons medially almost smooth with some rugae, laterally with oblique striae (in latter concave medially, with sparse, fine and obsolete punctures laterally); the length of maxillary palp 0.7 times height of head (in latter 0.5 times) and dorsal carinae of first tergite obscure or only visible basally (in latter present in basal half).
Remark. The tarsus of left hindleg of holotype missing. Most of the flagellomeres of paratype missing.
