Schizaphis laingi Eastop 1956 = Schizaphis nigerrima (Hille Ris Lambers 1931)

Schizaphis laingi, described from undetermined grasses in western UK, was distinguished from S. nigerrima by frequent presence of marginal tubercles on abdominal segments 2–6, a shorter antennal processus terminalis, and more caudal hairs. Subsequent UK collections suggest that these differences are seasonal.
