Isotomurus tricolor
Quite close, Ken ;-)
Isotomurus, given only macrosetae are present on the last body segments.
Note the straight seta on the 2nd abdominal segment: a bothriotrichum, diagnostic to Isotomurus.

Ah...
I thought the bilateral stripes eliminated
tricolor
, given the ID section of the
Info Page
.
Still, I'm happy to have hit upon the correct genus. :)

I agree it is quite confusing ;-)
Note that the bilateral 'stripes' of tricolor
1. are only present in well pigmented adult specimens
2. are only partly distinct as stripes: only on the abdominal segments, the bilateral pigment is stripe-like. On the thoracic segments the bilateral pigment is absent. Note that the coxae are pigmented, not the thoracic tergum.
In palustris, the bilateral stripes are from thorax to abdomen and distinctly on the terga.
Feel free to add this to the info page.

thinking the same, but the markings are different. Maybe an immature?
