Correct species identification in field surveys determines the success of natural enemies in biological control
programmes. For such surveys, short-keys, mainly based on one or two morphological characters, are
used as a quick-tool to ascertain species identification. However, when the whole character plasticity (the
one used in the short-keys) has not been covered or is shared between species, some misidentifications
could occur. Aphytis (Hymenoptera: Aphelinidae) are one of the most important natural enemies of
armoured scales around the world. Pupa pigmentation pattern is the main character used in short-keys
for species identification in field surveys in citrus production areas. However, field surveys in the Iberian
Peninsula since 1998 have led to the misidentification of an increasing number of specimens that do not
fit with the alpha-taxonomical keys for the described Aphytis species.
Integrative taxonomy has recently been used as a helpful tool in solving species limits and/or species
assignments. In this study, we present the unification of molecular taxonomy (based on DNA barcodes)
and traditional taxonomy, including biological studies, to clarify the species status of unidentified fieldcollected
individuals of Aphytis lingnanensis group and Aphytis chrysomphali group, which parasitize
California Red Scale Aonidiella aurantii (Maskell) (Hemiptera: Diaspididae).
Our results (molecular, morphological and biological) show that these specimens belong to either
Aphytis melinus DeBach or A. chrysomphali (Mercet) species, despite their differences in pupa pigmentation.
We propose an integrative taxonomic key for assignment to the correct species for the use in field
surveys on CRS in the Iberian Peninsula which takes into account the plasticity of pupa characters and a
DNA barcode key for its use with damaged or immature specimens. [-]
