Diagnosis.

Body yellowish or brownish, occasionally black. Head wider than mesosoma, lower margin of clypeus bilobed. Antennal insertion slightly above or on lower ocular line, antennal formula 11153 in female, 11143 in male. Prothorax with pronotum rectangular, almost as long as mesoscutum; mesothorax dorsally convex, notauli deep and complete, scutellum convex; propodeum with an inverted V-shaped basal submedian carina. Fore wing with marginal vein broadened, mostly with dark brown maculae below marginal vein; postmarginal vein slightly shorter than marginal vein. Hind femur distinctly thickened. Petiole elongated, gaster compressed from side-to-side.

Biology.

Most species develop in plant galls or in figs, some extralimital species are recorded as parasitoids. The hosts involved Hymenoptera ( Pteromalidae , Eulophidae , Eurytomidae , Tanaostigmatidae , Torymidae , Tenthredinidae , Cynipidae and Cecidomyiidae ), Lepidoptera ( Cecidosidae , and Gelechiidae ), Diptera ( Prodoxidae ) and Hemiptera ( Psyllidae ) ( Noyes 2020).

Distribution.

China (Hainan, Fujian, Hunan, Guangxi, Hongkong, Taiwan) ( Luo et al. 1987; Huang et al. 1988; Beardsley 1998; Chen et al. 1999; Xu et al. 2002). The species of Sycophila are reported throughout the world ( Narendran 1994; Noyes 2020).
