IMG_2987 - Spanioneura sanguinea

Psylla sanguinea is the correct name now

in case you wanted to update your personal records.

The epithet sanguinea clearly applies to the red winter form, as in Tom Murray's specimen:

But it is the oldest available name and therefore must be used. trimaculata joins cerasi and astigmata as synonyms.

Psylla trimaculata?

Thank you all. Not sure about Robert but am pretty sure he's not talkin' about me.

Found a PDF with key and descriptions from Smithsonian Institution, United States National Museum, Bulletin 85, "A Monograph Of The Jumping Plant-Lice or Psyllidae Of the New World" here. (Might want to right click and download.) Makes me think this and the the other red spotted examples in the Guide are Psylla trimaculata. Also makes me wonder if Kerry Yurewicz's images under that species in the Guide are not P. Astigmata which is also found on Prunus. See page 155. Key on page 137. Maybe Astigmata is out of range.

I should mention that I'm pretty bad with keys and this one may be outdated.

Correct on all counts

You nailed it - this is P. trimaculata and Kerry Yurewicz's image is indeed astigmata. However, P. astigmata was synonymized with P. trimaculata by Osborn in 1922. Tuthill recognizes astigmata as a distinct var. of P. trimaculata, in addition to another form that is reddish in color with dark abdominal bands; Tuthill theorized that temperature was a contributing factor in pigmentation differences.

The three red spots on the thorax are diagnostic, but note also the extraordinary long antennae (greater than 2.5x head width), lack of pterostigma, and relatively short female genital segment, all of which are considered key characters by Tuthill. These characters become much more useful in diagnosing the atypical variants.
