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 <i>Parlatoria ziziphi</i> were identified based on morphological characteristics and 28SrDNA sequences. They comprised 4 ectoparasitoids: <i>A. chrysomphali</i> (Mercet), <i>Aphytis jinshanensis</i> Wang & Huang, <b>sp.n.</b>, <i>Aphytis nigromaculata</i> Wang & Huang, <b>sp.n.</b>, and <i>A.</i> nr. <i>melinus</i> DeBach, and 1 endoparasitoid, <i>Encarsia citrina</i> (Craw). The 2 new species are described and illustrated in detail, and the relationships of the 4 <i>Aphytis</i> parasitoids treated here are analyzed, resulting in a phylogenetic tree based on 28SrDNA sequences. Moreover, the 5 <i>Aphytis</i> 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.
