Head of ♀ comparatively long and nearly parallel-sided behind eyes in dorsal view, with deep medial depression in front of occipital carina and with pair of shallow lateral depressions (Fig. 127); vertex medially distinctly above level of ocelli in lateral view, densely punctulate and long (Fig. 128); occipital carina wide lamelliform (Figs 128 and 135); propleuron in lateral view slender and 1.0 - 1.2 x as long as mesoscutum in front of tegula (Fig. 129) and in ventral view narrow anteriorly (Fig. 132); middle lobe of mesoscutum without fine transverse elements anteriorly, only very finely coriaceous between distinct punctures and posteriorly vermiculate (Fig. 130); ovipositor sheath about 0.9 x as long as body, its white or ivory apical part about 1.5 x as long as hind basitarsus. Easily confused with G. corniculigerum Enderlein, 1913; differs mainly by the shape of the head in dorsal view (nearly parallel-sided behind eyes in female and distinctly contracted in G. corniculigerum), the sculpture of the middle lobe of the mesoscutum (without fine transverse elements anteriorly; present in G. corniculigerum), the anteriorly more slender propleuron and the shorter pale part of the ovipositor sheath (1.0 - 2.1 x versus 2.8 - 3.5 x as long as hind basitarsus in G. corniculigerum).	en	Tan, Jiang-Li, Achterberg, Cornelis van, Wu, Jia-Xuan, Wang, Hang, Zhang, Qi-Jing (2021): An illustrated key to the species of Gasteruption Latreille (Hymenoptera, Gasteruptiidae) from Palaearctic China, with description of four new species.
