evaluation of coi and its2 sequences ability to distinguish lysiphlebus fabarum and lysiphlebus confusus (hymenoptera: aphidiidae)

all wasp species in the genus lysiphlebus fã¶rster are solitary endoparasitoids of aphids andconsidered a taxonomically difficult group. in this study a part of coi and its2 was used to distinguishtwo closely related species l. fabarum (marshall) and l. confusus tremblay & eady in iran. thesequencing with a similarity about 99.5% showed coi's inability to separate the species l. fabarum andl. confusus. the its2 region of the rdna partly separated the species with the similarity of 96.5-98.5%.the result is indicative of dna barcoding deficiency in the identification of the species, as the two generegions fail to efficiently separate the species.
