List compiled primarily from FLOW (Bourgoin 2013), also Metcalf (1957) and unpublished list by Lois O’Brien.

Economic Importance:

Limited. Species are uncommon.

Known host plants:

None listed in Metcalf & Bruner (1948) or Wilson et al. (1994)

Plant names from USDA PLANTS or Tropicos.

Recognition:

The Flatoidinae can be recognized by the wings being held in a shallowly – tentlike fashioned (“horizontally”), instead of parallel to the body.

A key to genus is provided in Metcalf & Bruner (1948), who also considers most forms of this genus (but no key is given to species).

The genus can be recognized by the head distinctly longer than broad (i.e., projecting in front of the eyes), “obtusely triangularly produced”.  Subcostal vein and costal margin undulate, tegmina not narrowed distally.  the head is also produced in Flatarissa Metcalf & Bruner, but that genus is restricted to Cuba.

Collecting

Pseudoflatoides is uncommonly encountered, but may be found by beating, inspection or occasionally at lights.
