Biology. Pediobius foveolatus was more often recorded as a primary parasitoid, and occasionally recorded as a secondary parasitoid ( Noyes 2016). In China, P. foveolatus has been recorded only from Henosepilachna vigintioctopunctata (Fabricius) ( Coleoptera : Coccinellidae ) so far.

Distribution in China. Widely distributed in CHINA: Beijing, Fujian, Guangdong, Guangxi, Jiangsu, Hainan, Hong Kong, Hubei, Guangdong, Guangxi, Jiangxi, Jiangsu, Shanxi, Sichuan, Tibet, Yunnan.

Remarks. Pediobius foveolatus has been widely found in China. There is some variation in body colour and mesosoma sculpture among different populations. Most specimens have body metallic blue green, and some specimens have body dull with little metallic reflections. For Chinese specimens examined here, sometimes, MLM with reticulation coarse in anterior median part, slightly and transversely elongate in remaining part before notaular depressions, and longitudinally elongate between notaular depressions.

To some extent, P. foveolatus is similar to P. bifoveolatus (Ashmead) and P. koebelei Kamijo. These three species share similar sculpture of scutellum. However, the space between notaular depressions is quite narrow and vertex has sutures running from posterior ocelli to eyes and occipital carina in P. bifoveolatus and P. koebelei . In this regard, the latter two species appear to be closely allied to species with those sutures on vertex, like P. anomalus and P. soror (see also remarks under P. anomalus ).
