Kymachrysa, a new genus of Nearctic Green Lacewings (Neuroptera, Chrysopidae, Chrysopini).

Tauber CA, Garland JA - Zookeys (2014)

Bottom Line: Here we demonstrate that adults (both sexes) and larvae of these species share a set of features that distinguishes them from currently described genera.Thus, to promote nomenclatural stability in Chrysopidae, we describe Kymachrysa, a gen. n. that contains the two species - Kymachrysa intacta (Navás), comb. n. and Kymachrysa placita (Banks), comb. n..Also, we present modifications for the current generic-level key, illustrations, as well as biological information for identifying the genus and its known species.

ABSTRACT
Two North American species of green lacewings have undergone a number of changes in their generic assignments and are currently classified as incertae sedis. Here we demonstrate that adults (both sexes) and larvae of these species share a set of features that distinguishes them from currently described genera. Thus, to promote nomenclatural stability in Chrysopidae, we describe Kymachrysa, a gen. n. that contains the two species - Kymachrysa intacta (Navás), comb. n. and Kymachrysa placita (Banks), comb. n.. Also, we present modifications for the current generic-level key, illustrations, as well as biological information for identifying the genus and its known species.

Figure 5: Kymachrysa intacta external adult features. Note variation in the presence, darkness, and size of head and thoracic markings. A–C Head (dorsal) D, E Head (frontal) F Head, prothorax (lateral) G, H Head, prothorax, mesothorax (dorsal) I Thorax (dorsal) J Head, thorax (lateral) A, D, G, I, J California, TRC B, E, F, H Colorado, TRC; C New York, TRC.

Mentions: Adult (Figs 4, 5, 8C, D). Delicate, slender, medium sized (forewing length, Kymachrysa placita: 11–13 mm; Kymachrysa intacta 11–15 mm), predominantly green with yellow longitudinal stripe, mesally. Head (Figs 4, 5). Vertex with pair of crescent-shaped, red or brown sublateral marks (sometimes absent or faint), usually with lateral red or brown stripe near margin of eye; frons with or without markings; gena with red or brown longitudinal markings. Distal segments of labial, maxillary palpi with elongate, lateral, black marks. Antenna cream colored, without markings. Thorax (Figs 4E–H, 5F–J, 8C, D). Prothorax variable in length and shape (probably developmental variation), usually long, tapered distally; dorsum without lateral stripes, but usually with irregular, red or brownish, sublateral markings (especially western, southern specimens); mesothorax, metathorax with or without markings. Legs mostly light green, without markings, with numerous dark brown to black setae; tarsal claws with deep U-shaped to V-shaped cleft.
