Identification
Elipsocinae can be distinguished from other elipsocid by features of wing venation and genital structure. Forewings have a characteristic venation pattern with reduced number of . Males possess distinctive phallosome structures useful for -level identification. Separation from other psocopteran subfamilies requires examination of wing venation, tarsal segmentation, and genital .

Taxonomic history
Elipsocinae was established by Pearman in 1936 as part of a reorganization of psocopteran classification. The has undergone various revisions, with occasionally transferred to or from related subfamilies based on morphological studies.
Research status
Many within Elipsocinae remain poorly studied, particularly in tropical regions. Identification to species level often requires microscopic examination of slide-mounted specimens.
