Host. This is the first known record of A. aligarhensis parasitizing the obscure mealybug Pseudococcus viburni . The relationship has been found on Citrus reticulata Blanco, Citrus sinensis (L.) Osbeck and Diospyros kaki L.f.

Comments. It seems to be a widely distributed species in the Old World and introduced in USA ( Noyes & Hayat 1994; Çalişkan et al. 2016). This species has been long treated in Spain as Anagyrus diversicornis Mercet , with A. aligarhensis as synonym established by Noyes and Hayat (1994); but being a preoccupied name by A. diversicornis (Howard) , the next available name is A. aligarhensis ( Noyes 2000) . The specimens were identified by comparison with literature descriptions.
