Leuronotina

Species in Leuronotina are distinguished from related genera by their lichen-mimicking coloration, which includes variable shades of green, brown, and black with contrasting speckling and banding patterns. Leuronotina ritensis in particular exhibits striking blue-green coloration matching crustose lichens. The genus can be separated from the superficially similar Trimerotropis by geographic distribution and subtle morphological differences; Leuronotina species occur in the southwestern U.S. and southward, while Trimerotropis saxatilis occupies eastern glade habitats. Specific identification to species level requires examination of hind tibia coloration, wing length, and male genitalia.

Species in this genus inhabit rocky outcrops, sandstone glades, and cliff faces where crustose lichens are abundant. These habitats are typically characterized by exposed rock surfaces with variable lichen cover, ranging from heavily encrusted to barren areas. The specific microhabitat requirements relate directly to their crypsis strategy, as their coloration provides effective camouflage only within lichen-dominated environments.

Recorded from Arizona (United States), Mexico (central and northeastern regions), Guatemala, and Costa Rica. The genus shows a predominantly Mesoamerican distribution pattern extending northward into the southwestern United States.

Adults and nymphs exhibit crypsis through color matching with lichen substrates, remaining motionless to avoid detection. When disturbed, individuals make short escape flights with interrupted buzzing crepitation, after which they typically land on lichen-covered surfaces and become difficult to relocate. The effectiveness of their camouflage depends on remaining within appropriate lichen-dominated microhabitats.

• TrimerotropisParticularly Trimerotropis saxatilis, which exhibits convergent lichen-mimicking coloration and ecology; distinguished by geographic separation (eastern vs. southwestern U.S.) and subtle morphological differences in wing venation and genitalia.
