A New Species and a New Subgenus of Sitomyzus Hille Ris Lambers (Homoptera: Aphididae)

Sitomyzus was erected for a grass-feeding species of aphid, S. vibei H.R.L. which is known to occur only in Greenland (Hille Ris Lambers, 1952). In this paper a second species is desdribed from British Columbia, and a third, common, widespread species, Rhopalosiphum rhois Monell, is also assigned to...

Description
Summary:Sitomyzus was erected for a grass-feeding species of aphid, S. vibei H.R.L. which is known to occur only in Greenland (Hille Ris Lambers, 1952). In this paper a second species is desdribed from British Columbia, and a third, common, widespread species, Rhopalosiphum rhois Monell, is also assigned to this genus. The latter species is placed in Sitomyzus largely on the basis of similarities between the alate viviparae of rhois and those of other representatives of this genus. The apterae of rhois are very distinct however, and a new subgenus is herein erected for this species.
