Larval habits range from free leaf feeders to gall formers, others are leaf edge rollers, leaf
miners, and some live and feed inside the fruits of rosaceous plants. The taxonomy of many
groups is imperfectly known and few have been recently studied. Because of their abundance in
the arctic region, many represent holarctic species, and a worker is met with the major obstacle
of having to become familiar with the innumerable forms described from Eurasia. Variation is
another factor since the extreme arctic climate may influence major morphological and color dif-
ferences within species. For example, females of Amauroneviatus abnonnis (Holmgren) are
normally brachypterous, but females with normal wings also exist. Some of the gall forming
groups apparently contain species complexes where there are practically no adequate
morphological characters for species separation and where identity may have to be based on
specific host records and accompanying biological information. Extensive field work and
knowledge of the world fauna will be essential to the study of most groups, and such facilities
are not available to most taxonomists.

Unplaced Taxa of Nematinae

The following species are of questionable generic assignment due to inadequate descriptions
and inaccessibility, loss, or poor condition of type material. Three species described by Cameron
from northern Mexico are included; though not strictly within the scope of this Catalog, they un-
doubtedly represent southern extensions of northern species.
