Pleasing Fungus Beetle - Triplax

Pleasing Fungus Beetle - Triplax
Guelph, Wellington, Ontario, Canada
May 23, 2007
Size: 5 mm
Found on Pleurotus fungi on a really hot day (About 89°F).

opinion of Paul Skelley:
"Triplax frosti is hard even with the specimen. The key characters of punctures are not really evident to me in the picture, either way. And the scutellum is not as yellow as on the few T. frosti at hand. It could be."

Triplax frosti Casey, 1924, i suppose

What to look for?
I have slightly better images and the specimen on hand ... or can scope it in the next day or two to confirm any minute details.

 
pls do both
i mean, post good pix + scope specimens (if elytra with no basal margin and impunctate intervals, then this is it)

 
Posted
Okay, I've posted the image. Also scoped it ... the elytra are lacking the basal margin, but I'm not sure about the impunctate intervals part.

 
no, the pinned one's different -- pls unlink
scutellum color!

 
?
I'm certain that both photos show the same specimen.

 
well, i'm not
in the live pic scutellum is obviously concolorous with the pronotum

 
Well then, maybe there were
two species or varieties at the site, and I shot one but collected the other.

it's not unusual for multiple spp to live on the same fungus. pls exert yourself to shoot and catch more next time -- as you see, the guide has them badly underrepresented. (they key out easily, and we can always ask Dr Skelly, too -- he's been good to us :) thanks in advance, Stephen!

 
Will do
I should be hiking the Arboretum quite a bit come spring. Will look for them then.
