A molecularphylogeny offorktail damselflies(genus Ischnura)revealsa dynamic macroevolutionary history of female colour polymorphisms.

abstract：:Relationships among the microgastroid complex of braconid wasps were investigated using sequence data from the 16S mitochondrial rDNA and 28S (D2 expansion region) nuclear rDNA genes, as well as morphological data. Parsimony analysis of these gene fragments, both separately and combined, indicated that Neoneurus (Neon...
