Elipsocus abdominalis (?)

This is a provisional and tentative ID - I am not 100% certain and so won't be formally recording it unless I'm able to further experience with the group or am advised by someone more experienced. It was knocked out of mistletoe growing on apple. Its forewing was about 3.1mm long.

Although the areola postica was joined to the median vein on one wing, it was clearly separate on the other. Keying it as joined soon led to a dead end but keying it as seperate soon led to Elipsocus which appears to be correct, so I assume it was the wing where it was joined that was aberrant. Getting it to species was tricky, and perhaps certain ID would have depended on me preserving the specimen differently. It was a male and the colour of the upperside of the abdomen appears to be the only useful character to separate males of several species in this genus. When live I was unable to observe the upperside of the abdomen due to the wings covering it, and on death the specimen dried quickly making it difficult to interpret. The only way I was going to be able to see the abdomen properly was to clear it first in potassium hydroxide, but would that remove any pigment? I left it in only a short while, hoping that pigment would be preserved. What came out appeared to be unpigmented except for the darkened (sclerotised?) plate at the apex. This appears to match abdominalis, but I am not confident whether or not one of the other species would necessarily have retained its pigment given the treatment I subjected it to.
