Aphrophoridae - Spittle Bug - Ctenarytaina spatulata

Aphrophoridae - Spittle Bug - Ctenarytaina spatulata
Mt. Davidson, San Francisco County, California, USA
April 3, 2010

Moved from Spondyliaspidinae. Parallel veins = Ctenarytaina, vein Cu1a greatly exceeding the furcation of M with yellowish head and pronotum = C. spatulata (at least as of now; the introduction of more eucalypt psyllids in the future to complicate matters is always a possibility)

Moved from Euphalerus.

Moved tentatively based on Ray Gill's suggestion
Moved from Psyllidae.

I want to believe
but analysis of the wing venation suggests that this is actually an australian Eucalyptus psyllid in the subfamily Spondyliaspidinae.

I compiled into one image a rough plate consisting of 8 of the 12 nearctic Euphalerus (including those now included in the genus Nyctiphalerus:

While some species are absent, notably the ones described by Bliven, it shows some of the trends in the group.

Exhibit B: I outlined in red the wing venation of the psyllid in this photo:

Note how veins Rs, M, and Cu run parallel; this is a trait not seen in our North American fauna, but is present in some Australian Spondyliaspidinae, quite a few of which are established in California. See, for example:

(And some more images here )

So unfortunately, that means that we lose Euphalerus and the subfamily Macrocorsinae from bugguide for now. As Euphalerus is currently defined, there are only three species; one on Cercocarpus from Idaho, one on Piscidia from Florida, and a poorly defined species from Texas. Hopefully somebody can find one.

thanks again, Chris
tremendous job figuring it out
do what you have to do and move stuff to the best of your understanding without hesitation.
just make sure to mark the missing taxa in the psyllid synopsis with an asterisk.
btw, you will make further updates much easier if you include 'empty' links for the missing taxa, too -- use [i][url=node/view/]*Phantomura[/url][/i] and simply insert page # after "view/" once the gap has been filled

there is also a minor advantage in using the ยท divider between genera, rather than a comma

the mirid page uses an obsolete model, i have streamlined and simplified many things since

i also grew to believe that, more often than not, visual guides work better when entirely separated from taxonomy and nomenclature
i no longer like those combined pages that mix two separate tasks quite awkwardly and often require a lot of scrolling

Thanks for the tips =v=
I'll edit the synopsis accordingly. I'm still learning as I go when it comes to how to best present info on the guide pages; I think I told you earlier that I modeled the synopsis after the mirid page, didn't know that it was an outdated model. Do you have an example of a page that uses something more recent? I can always update the guide to streamline it with the rest of the site. And if you have any other suggestions that would improve the page or make it more useful I'm very open to ideas.

i'll answer offline, ok?
i shouldn't have started this unrelated discussion here in the first place...

Even though you can't see the long antennae from this view, the distinctive wing venation (3 forked veins meeting near the middle of the wing) is distinctive.

sorry, duplicate entry
