Saltusaphidinae is a of aphids comprising 49 across 12 . Members are commonly known as sedge aphids due to their specialized association with Cyperaceae (sedges). The group is divided into two tribes: Saltusaphidini and Thripsaphidini. One species, Iziphya leegei, is exceptional in feeding on Juncus (rushes) rather than sedges.

Identification

Saltusaphidinae are distinguished from other by their -plant specificity to sedges and morphological characters including features of the , siphunculi, and cauda. The subfamily has been characterized by 10 generic, 17 , and 2 embryo characters in phylogenetic studies. within Saltusaphidinae include Allaphis, Iziphya, Nevskya, Saltusaphis, Sminthuraphis, Strenaphis, Subiziphya, Juncobia, Neosaltusaphis, Peltaphis, Subsaltusaphis, and Thripsaphis.

Habitat

Wetland and moist environments where sedges (Cyperaceae) and rushes (Juncus) occur. include marshes, fens, wet meadows, and riparian zones.

Distribution

Worldwide distribution. Specific distribution records are documented for each of the 49 recognized .

Diet

Phloem feeding on plants. Specialized on Cyperaceae (sedges) for nearly all ; Iziphya leegei feeds on Juncus spp.

Host Associations

  • Cyperaceae - primary sedges; for all except Iziphya leegei
  • Juncus - primary rushes; for Iziphya leegei only

Similar Taxa

  • MacropodaphisFormerly considered part of Saltusaphidinae; phylogenetic analysis placed it in separate Macropodaphidinae, sister group to Saltusaphidinae
  • CalaphidinaeSome classifications (e.g., Catalogue of Life) treat Saltusaphidinae as subtribe within Calaphidinae rather than separate

Taxonomic placement

The has been variously placed. Some phylogenetic analyses support Saltusaphidinae within Drepanosiphidae, while other classifications (e.g., Catalogue of Life) place it as subtribe Saltusaphidini within Calaphidinae. The phylogenetic analysis by Zhang & Qiao (1998) proposed several taxonomic changes: Allaphis as subgenus of Thripsaphis; Stenaphis as subgenus of Subsaltusaphis; and Peltaphis as independent .

Genera composition

Two tribes are recognized: Saltusaphidini (Iziphya, Juncobia, Nevskya, Saltusaphis, Sminthuraphis, Strenaphis, Subiziphya) and Thripsaphidini (Allaphis, Neosaltusaphis, Peltaphis, Subsaltusaphis, Thripsaphis). Note that some names in sources vary (e.g., Stenaphis vs. Strenaphis, Nevskya vs. Nevskyella).
