Abstract

Synophromorpha Ashmead is a genus of cynipid inquilines associated with Diastrophus galls on Riibus bushes. All described species, except S. tobiasi which doubtfully belongs to the genus, are restricted to the Nearctic Region. Synophromorpha laketanii sp. n., a fifth species of this genus, is described from Japan. This is the first reliable record of the genus from the Palaearctic Region and reveals that Synophromorpha has a disjunct distribution. Adults of 5. laketanii emerged from stem galls on Rubus palmatiis. Study of Periclistiis natalis and P. qiiinlani showed that Synophromorpha and Periclistiis intergrade. It is considered preferable to retain these two as separate genera on the basis of their host associations.
