"indoor" barkfly for ID, please

Barkfly seen 20th Jan, found in a container with a residue of rat poison.

The barkfly was initially active, and then perhaps the stress of the situation, plus the action of the rat poison, was too much, and it suddenly died.

I assume the blue fluid came from the rear, as it died.


About 1.5 mm long, very dark brown, with extensive brown hair on the body.

An expert on "outdoor" barkflies has examined the specimen, and states:


"The  barkfly is micropterous, the wings being tiny lobes without distinct venation,  and the tarsi are two-segmented. That places the specimen in either  Amphipsocidae, Ectopsocidae, Lachesillidae or Elipsocidae. It seems most likely  that it is a Lachesilla species as these are found in domestic environments."


Is it possible to identify it to species level, if I supply the specimen? One not very good image attached - to give an impression only.
