On the genus Coccophagus Westwood (Hymenoptera, Aphelinidae) from Xishuangbanna Rainforest. Contribution I: Two new species of the Coccophagusvarius group, with an identification key and phylogenetic analysis.

Two new species belonging to the varius group of Coccophagus , C.breviclavulus sp. nov. and C.perlucidus sp. nov. , are described from Xishuangbanna Rainforest (China, Yunnan). Coccophagusanchoroides (Huang) and C.yunnana Wang, Huang & Polaszek are recorded. A tentative key to world species of this group is provided. Partial nuclear ribosomal 28S-D2 of these four species and other six species were sequenced and subjected to a phylogenetic analysis. Phylogeny of C.varius group is discussed.
