03FD422B9070CA6DFEF4B4F1FE57FD98.taxon	discussion	Remarks The female of Eretmocerus lannae sp. nov. is unusual in having a single seta on the mesoscutal side lobe, a character observed for the first time in the genus Eretmocerus. Generally, Eretmocerus species have 2 – 3 setae on the side lobe. The new species is close to E. trialeurodis Hayat, but differs from it in the length of ovipositor, which is 0.86 × clava length and subequal in length to the mid tibia, and in having the mid tibial spur 0.52 × the basitarsus, and with fewer setae on the vertex. Eretmocerus lannae sp. nov. is a potential biocontrol agent of A. floccosus; the parasitoid population was found to be abundant. Although A. floccosus was infesting heavily both the golden dewdrop (D. repens) and guava (P. guajava), only the population on guava was parasitized by E. lannae. The reason for this selective host preference could be plant secondary metabolites, or possibly that the population of A. floccosus on golden dewdrop secretes more wax than the guava population, creating unfavourable conditions for parasitization.	en	Shih, Yuan Tung, Polaszek, Andrew, Dubey, Anil Kumar, Chen, Shu-Pei, Yang, Ping-Shih, Ko, Chiun-Cheng (2015): New species of Eretmocerus Haldeman (Hymenoptera: Aphelinidae) parasitizing Crenidorsum turpiniae (Takahashi) and Aleurothrixus floccosus (Maskell) (Hemiptera: Aleyrodidae) from Taiwan.
