Fallapion
Kissinger, 1968
Fallapion is a of minute seed in the Brentidae ( Apioninae), established by Kissinger in 1968. Members of this genus are small characterized by their elongated and compact body form typical of apionine weevils. The genus is taxonomically distinct from the broader Apion genus complex, with -level requiring detailed morphological examination. Observations of this genus are relatively sparse, with limited documented occurrences in databases.

Identification
Fallapion are distinguished from related apionine by rostral and antennal characteristics established in Kissinger's 1968 revision. The genus can be separated from Apion stricto by features of the rostral groove and scrobe placement. Species-level identification requires examination of male and detailed rostral proportions. The small size (likely under 5 mm based on norms) and slender are consistent with other minute brentid .

Distribution
Documented observations span multiple continents, including North America and Europe, though precise range boundaries remain undefined due to limited sampling. Specific country records are sparse in available databases.
Similar Taxa
- ApionHistorically broad from which Fallapion was segregated; shares general body plan but differs in rostral structure and antennal insertion details per Kissinger's revision.
- PseudapionAnother apionine with similar minute size and seed ; distinguished by male genitalic and rostral groove .

Taxonomic Note
placement varies in literature: GBIF and iNaturalist list Brentidae, while NCBI lists Apionidae. Modern treatments generally recognize Apioninae as a of Brentidae rather than a separate family, resolving this discrepancy.
Nomenclatural History
Established by David G. Kissinger in 1968 as part of his taxonomic revision of North Apioninae, reflecting the splitting of the historically heterogeneous Apion .
