摘要
记述了我国细蜂科叉齿细蜂属Exallonyx叉齿细蜂亚属Exallonyx的环柄细蜂种团cingulatus-group2新种:强脊叉齿细蜂Exallonyxfirmussp.nov.和无凹叉齿细蜂Exallonyxexfoveatussp.nov.。描述了其形态特征并与近似种做了比较。模式标本存于浙江大学寄生蜂标本室。
Exallonyx firmus sp. nov. and Exallonyx exfoveatus sp. nov. are described and illustrated in the paper. Both species belong to the cingulatus-group of the genus Exallonyx Kieffer, 1904. A key to the Chinese species is given. The type specimens are deposited in the Hymenopteran COllection of Zhejiang University.
Exallonyx firmus sp. nov. (Figs. 1-5)
This species resembles ExaUonyx mindorensis Townes & Townes, 1981, but differents from the later in: 1) epomia strong; 2) median groove on syntergite with four lateral grooves on each side; 3) ovipositor sheath with irregular longitudinal sculptures at anterior 0.60.
Holotype ♀, Zhejiang, Tianmu Mountain (30.26°N, 119.34°E), 12 May 1999, ZHAO Ming-Shui, No.999351. Paratypes: 3♀♀, locality and collector same as the holotype. 5 Sep. 1998, 20 May 1999, 4 July 1999, No. 994974, 996467, 996560; 1 ♀, locality same as the holotype, 12 June 1993, MA Yun, No. 934189.
Exallonyx exfoveatus sp. nov. (Figs.6-11)
The new species is similar to Exallonyx chaoi He et Fan, 2004, but can be easily distinguished from the later by: 1 ) second and tenth flagellar segments both 3.1 times as long as wide; 2) upper margin of pronotum with a single row of hairs; 3) lower part of mesopleural suture not foveate; 4) median longitudinal groove on syntergite reaching 0.9 to space between thyridia, sublateral grooves 0.5 times as long as median groove.
Holotype ♂, Shaanxi, Qinling (34.14° N, 106.54°E), 8 June 1998, DU Yu-Zhou, No. 983454. Paratype: 1 ♂, locality and date same as the holotype, MA Yun and DU Yu-Zhou, No. 983711.
