Tamaricades tamaricius Cai , comb. nov.

( Figs 6A–E , 7C, 7I , 8B )

Megalopsius tamaricius Cai, 1998: 57 , fig. 3 (1–7).

Pronotum 1.5x as long as crown.

Male genitalia. Pygophore short and wide, with a few macrosetae near caudal margin, caudal margin strongly bilobed, without appendages. Fused subgenital plates and valve longer than wide, with truncate caudal margin, with a few setae. Apophysis of style foot-like. Aedeagus short and stout, hood-like in caudal view; gonopore apical.

Female genitalia. Hind margin of seventh sternite sinuate with median notch.

Material examined. China, Xinjiang Autonomous Region : 4♂, 2♀♀, Qiangwu Jiantan, 3. vii. 1985 ( NWAFU) ; 1♀, Qiangwu Jiantan, 24. vi. 1985 ( NWAFU) ; Gansu: 3♂, Zhangye, 24. vii. 1985, coll. Lu Jinsheng ( NWAFU) ; Ningxia Autonomous Region : 4♂, Yinchuan, 6. vii. 1982 , host: Tamarix ramosissma Ledeb ; 1♂, Demos Park, 6. vii. 1981, coll. Jin Gentao ( SHEM) .

Distribution. Europe, China (Xinjiang, Neimenggu, Gansu, Ningxia).

Remarks. The identity of this species is taken from Cai et al (1998). This species could be G. taeniatus Emeljanov (1979, fig. 36) based on the markings on the vertex but as this species was described only from females the synonymy is uncertain.
