The Parasitoids of Parlatoria ziziphi (Lucas) (Hemiptera: Diaspididae): With Descriptions of Two New Species of Aphytis (Hymenoptera: Aphelinidae) from China, and a Note on Aphytis Species with Black-Tipped Mid-Tibiae in the Male

During investigations in the Fujian and Hunan Provinces of China, 5 parasitoids associated with Parlatoria ziziphi were identified based on morphological characteristics and 28SrDNA sequences. They comprised 4 ectoparasitoids: A. chrysomphali (Mercet), Aphytis jinshanensis Wang & Huang, sp.n., Aphytis nigromaculata Wang & Huang, sp.n., and A. nr. melinus DeBach, and 1 endoparasitoid, Encarsia citrina (Craw). The 2 new species are described and illustrated in detail, and the relationships of the 4 Aphytis parasitoids treated here are analyzed, resulting in a phylogenetic tree based on 28SrDNA sequences. Moreover, the 5 Aphytis species (including 1 new species described in this work) having the mid-tibia tipped with black in the male are summarized with their scale hosts and distribution, and an identification key to these species is provided.
