Kymachrysa placita
(Banks, 1908)
Kymachrysa placita is a of green lacewing in the Chrysopidae, first described by Nathan Banks in 1908. The Kymachrysa is a small group within the Chrysopidae, distinguished from related genera by genitalic characters and wing venation patterns. Like other chrysopids, are likely predatory, though specific ecological details for this species remain poorly documented. The species is known from limited historical specimens.

Identification
of Kymachrysa placita can be distinguished from other Chrysopidae by features of the male genitalia, particularly the structure of the gonarcus and parameres. The Kymachrysa is characterized by specific wing venation patterns including the arrangement of crossveins in the costal space. Separation from the closely related genus Chrysoperla requires examination of these subtle morphological characters.
Distribution
United States; historical records indicate occurrence in the eastern and central regions. Specific locality data is sparse due to limited collection and reporting.
Similar Taxa
- Chrysoperla spp.Similar appearance as green lacewings; distinguished by genitalic and wing venation details requiring microscopic examination.
- Chrysopa spp.Overlaps in general body form and coloration; Kymachrysa differs in genitalic structure and specific wing crossvein patterns.
More Details
Taxonomic history
The Kymachrysa was established to accommodate previously placed in Chrysopa that exhibit distinct genitalic and wing venation characteristics. Kymachrysa placita was transferred to this genus following revisionary work on Nearctic Chrysopidae.
Data deficiency
This is represented by very few specimens in museum collections, and no modern systematic surveys or ecological studies have been published. Most information is derived from the original description and subsequent taxonomic revisions.
