Subfamily Nematinae
Synonyms and other taxonomic changes
the recent revision(1) led to numerous names put in synonymy and the bulk of the subfamily (~80%) consolidated in just two speciose genera, Euura and Pristiphora, with no further subdivision offered; this makes it unpractical to implement in the Guide at this point, pending further study
Explanation of Names
Nematinae Thomson 1871
our largest subfamily, with >430 spp. in 30 genera in our area (incl. undescribed spp.)(2)(3), and world's second largest subfamily, with >1250 spp. in ~50 genera(4)
almost entirely restricted to Eurasia and North America(5)
Most spp. are external leaf feeders; some form galls, mine leaves/petioles, or feed in developing fruit(3)
