Uroleucon pseudambrosiae (Olive) and Hyperomyzus pallidus Hille Ris Lambers (Hemiptera: Aphididae) are recorded for the first time from India on Sow thistle Sonchus arvensis L.. Apterae of both these aphids were found congregating and sucking the sap from the S. arvensis L. stem and both the surfaces of leaves. A key to identify the aphid species infesting S. arvensis and photographic illustrations of live and mounted apterous viviparous females, of all nine species of aphids infesting S. arvensis L. in India, are provided.
