Osbornia sp. - Tylanira ustulata

Osbornia sp. - Tylanira ustulata
Tucson, Pima County, Arizona, USA
August 25, 2007
Attracted to the house lights. Looks like it might be related to Dictyssa sp.

Moved tentatively
...based on the outcome of a long offline discussion between experts; Lois O'Brien thinks this is the best match, although "most of [her] specimens have a shiny body with clearly defined veins [...], not a pollinose or rugose or whatever this is. But I have some small males in the unit that are fuzzier, but still have the wing shape, the spot on the wings, the three spots on the side of the head, the distance the head extends before the eye, the vertical angle between the frons and vertex, and the curve of the clypeus in lateral view."

Moved from Osbornia.

Osbornia
This appears to be the first record of a fully winged specimen in this genus. The vertical face and strongly inflated lower half are distinctive. So far, there is only one species known from AZ: O. arborea, which is uauslly rather short-winged with the terminal segments of the abdomen exposed, and a green and yellow color pattern (although darker forms are known from NM). It is supposed to feed on juniper. Please check trees growing near your house and see if you can find the flightless forms.

 
Not sure how you want this placed, Dr Hamilton
Does it go in Fulgoridae or Issidae or Acanaloniidae?? We had the same problem with Dictyobia.

 
Issidae
Dictyobia and the other reticulate-veined genera are best placed with Acanalonia; but all are probably Issidae semsu lato. Defining this family is proving troublesome, so I recommend a broad definition to include Acanaloniids.

 
Thank you....
...Dr. Hamilton. I know there are no junipers in this area but I will check the other trees that are around the house. So far, I've not found any candidates.
