Two new species of Eretmocerus Haldeman (Hymenoptera: Aphelinidae) parasitizing Aleurolobus rhododendri Takahashi and Dialeuropora decempunctata (Quaintance & Baker) (Hemiptera: Aleyrodidae) from Taiwan

Abstract

Background: Species of Eretmocerus Haldeman develop as primary ecto-endoparasites of whiteflies (Rose and Rosen 1992). Currently, the genus Eretmocerus comprises 86 species worldwide, of which 11 species have been previously recorded from Taiwan (Shih et al. 2015). Despite having been recently revised for Taiwan, two new species are here added to the Taiwan fauna. New information: Two new species, Eretmocerus garrywardi Ward sp. nov. and Eretmocerus liangyihchoui Shih sp. nov. found parasitizing Aleurolobus rhododendri Takahashi and Dialeuropora decempunctata respectively, are described. A key to females of Eretmocerus species occurring in Taiwan is provided.
