Monelliopsis caryae is a of in the Aphididae, first described by Monell in 1879. The specific epithet "caryae" indicates an association with Carya (hickory/pecan ). Taxonomic records show accepted status in major databases including Catalogue of Life, NCBI, and GBIF. Available distribution records are sparse and largely European (Belgium, Spain, France), though these may represent introduced or identification uncertainties given the North American genus. The species appears poorly documented in recent literature, with most research attention focused on the related Monelliopsis pecanis.

Distribution
Recorded from Belgium (doubtful), Spain, and France (rare to present) in GBIF. The European distribution is questionable given the North American origin of Carya; these records may represent introduced , misidentifications, or vagrant occurrences. No confirmed North American distribution records found in available sources, though the epithet and genus affinity suggest association with Carya .
