Cryptoneossa
Taylor, 1990
Cryptoneossa is a of () in the , established by Taylor in 1990. Psyllids in this family are small, phloem-feeding that often exhibit high specificity. The genus is part of the diverse superfamily, which contains numerous economically significant agricultural pests. within Cryptoneossa are associated with specific host plants, though detailed biological information remains limited for many .

Identification
Members of Cryptoneossa can be distinguished from other by genitalic characteristics, particularly features of the male and female proctiger. The genus is morphologically cryptic, requiring microscopic examination for definitive identification. Taylor's 1990 original description established diagnostic characters separating it from related genera such as Psylla and Cacopsylla, though these distinctions are subtle and require reference to .
Habitat
of Cryptoneossa inhabit environments where their specific plants occur. As with most , is largely determined by host distribution rather than independent environmental factors.
Distribution

Ecological Role
As phloem feeders, Cryptoneossa function as on their plants. They may serve as for and , though specific ecological relationships have not been documented.

Taxonomic history
Cryptoneossa was erected by Taylor in 1990 to accommodate previously placed in broader, polyphyletic within (now ). The genus name reflects the cryptic nature of its species, which are difficult to distinguish without detailed morphological study.
