Habitat
Tropical forest . Specific microhabitat preferences are poorly documented but likely include leaf litter, rotting wood, and other humid decaying organic matter typical for small Ectobiidae.
Distribution
Neotropical region: Brazil, Colombia, French Guiana, Guyana, and Panama. Records span lowland to mid-elevation tropical forests.
Ecological Role
Decomposer in tropical forest . As with other small Ectobiidae, likely contributes to nutrient cycling through consumption of decaying plant matter.

Taxonomic Note
placement has varied; some sources list Pseudophyllodromiidae as the family rather than Ectobiidae, reflecting ongoing taxonomic revision in Blattodea. The Chorisoneura is characterized by reduced wing venation with crossveins fewer in number and more irregularly placed than in related genera.
