In the last surveys of parasitoids conducted on Californian red scale, Aonidiella aurantii (Maskell), individuals of the genus Aphytis that present a black pigmentation of the pupa and exuvia have been detected. This description does not correspond to any of the parasitoids cited in Spain. Aphytis chrysomphali (Mercet), Aphytis melinus DeBach and Aphytis lingnanensis Compere, show a clearly differentiated pupa and exuviae pigmentation, without black pigmentation of pupa head in all cases. Therefore, these individuals have been assigned to a putative new species, Aphytis sp. lingnanensis group. Nevertheless, adult morphology corresponds to A. melinus, which pupa and exuviae are only black in the thorax. For this reason, the current taxonomic status of these individuals (black pupae) remains unclear, allowing us to suggest that it could be a cryptic species of A. melinus. Nowadays, cytochrome c oxidase I (COI) sequence is being considered as a taxonomic character (by Barcoding of Life initiative) and it is used for the description/unveiling of cryptic species. This work presents the use of the DNA barcodes (COI sequence) for the phylogenetic study of the black pupa individuals in the Aphytis group.
