Nomenclatural note on Flatormenis proxima – this species was for many years called “Anormenis septentrionalis”; however, O’Brien (1985) found that Spinola’s type specimen was not this species and the name had been misapplied. O’Brien (1985) determined that the correct species concept was that of Anormenis chloris (Melichar). Subsequently, Medler (2003) referred to the species to Flatormenis. Most recently (Bartlett et al. 2014) found that F. chloris was a synonym of F. proxima (Walker).
The name ‘Anormenis chloris‘ persists in popular – and sometimes technical – usage. It is sometimes called the ‘northern flatid planthopper’.
List compiled primarily from FLOW (Bourgoin 2013), also Metcalf (1957), and an unpublished list by Lois O’Brien.
Several common species, but not usually of major importance, although F. proxima is known to feed on a variety of ornamental and agricultural plants. Flatormenis proxima can be important on walnut. Flatormenis (esp. proxima) may occur in large numbers, but do little apparent damage to plants and have not been directly implicated in plant disease transmission (although this has not been excluded either). Wax deposits of immatures on ornamental plants may be unsightly.
[More to come; see FLOW]
- Flatormenis proxima is polyphagous; Juglans nigra L.(Juglandaceae, black walnut), Ostrya virginiana (Mill.) K. Koch (Betulaceae, hophornbeam), Quercus velutina Lam. (Fagaceae, black oak), Ulmus rubra Muhl. (Ulmaceae, slippery elm), Maclura pomifera (Raf.) C.K. Schneid. (Moraceae, osage orange), Morus rubraL. (Moraceae, red mulberry), Rumex obtusifolius L. (bitter dock, Polygonaceae),
- Phytolacca americana L. (American pokeweed, Phytolaccaceae), Liriodendron tulipifera L. (tuliptree, Magnoliaceae), Asimina triloba (L.) Dunal (Annonaceae, pawpaw), Sassafras albidum (Nutt.) Nees (Lauraceae, sassafras), Liquidambar styraciflua L.(Hamamelidaceae, sweetgum), Platanus occidentalis L. (Platanaceae, American sycamore), and 30 more in Wilson & McPhearson (1981)
Hosts from Nixon & McPherson (1977), Wilson & McPhearson (1981), and Wilson et al. (1994); plant names from USDA PLANTS or Tropicos. See also FLOW for additional hosts not listed above (although none indicated as of June 6, 2017).
There are no keys to species – it is best to use tails for species confirmation. Flatormenis has a strongly upcurved aedeagus. It is likely that the genus needs revision.
Compared to the U.S. Fauna:
Wings broad distally (not Selizini), held parallel to body (not Flatoidinae), frons not produced conically (vs. Siphanta); body color varied – often green (e.g., F. proxima), but may include brown, grey or red shades (e.g., F. saucia, F. squamulosa) or grey (F. panamensis); forewing with 2 submarginal veins separating 2 rows of cells at least at wing apex; forewings truncate distally.
Flatormenis proxima is probably the most abundant flatid in the eastern U.S. Often confused in the east with Ormenoides venusta, which is smaller with forewings rounded at apex, and the frons is wider in Flatormenis. In the western U.S., Flatormenis saucia is the most common and widespread flatid species. This species varies in color (greenish to orangish), but is often recognized by the orangish mesonotum. Flatormenis squamulosa and F. inferior are reported here based on specimens identified by Medler at TAMU. Flatormenis squamulosa is similar in size to F. proxima, but has a brownish cast. Flatormenis inferior is a smaller species. There is at least one undescribed Flatormenis in Arizona (and possibly 1 in California).
Illustrations of Genitalia (More will be posted as I encounter them)
Flatormenis can be commonly collected by general inspection, sweeping, or beating of woody vegetation. They are frequently conspicuous on their hosts.
Data for Flatormenis is available on Barcode of life (Under Anormenis) for F. chloris (as. A. chloris and A. proxima); and for Flatormenis panamaensis (although the genus is misspelled). Data for Flatormenis does not appear to be available on Genbank.
