Species Guides
1- Cryptoneossa triangula(Corymbia psyllid)
Cryptoneossa is a of psyllids (jumping plant lice) in the Aphalaridae, established by Taylor in 1990. Psyllids in this family are small, phloem-feeding hemipterans that often exhibit high plant specificity. The genus is part of the diverse Psylloidea 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 Aphalaridae by genitalic characteristics, particularly features of the male parameres 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 psyllids, is largely determined by host plant distribution rather than independent environmental factors.
Distribution
The has been recorded from Australia and New Zealand, with distributions tied to plants in these regions.
Life Cycle
Behavior
are active jumpers, using their enlarged hind to escape . Nymphs remain relatively immobile on plant foliage or stems.
Ecological Role
As phloem feeders, Cryptoneossa function as herbivores on their plants. They may serve as prey 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 Psyllidae (now Aphalaridae). The genus name reflects the cryptic nature of its species, which are difficult to distinguish without detailed morphological study.
