Imantimyia albiseta is very similar to some other members of the genus. It can be distinguished by examination of the specimen or very detailed images, because Imantimyia albiseta has an all-yellow face, and just a small triangular patch of short white hairs below the eye.  When images are likely to be this species, but cannot be confirmed with certainty they have been placed in a pink box.

Loxocera fulviventris has a mostly black face. Loxocera aristata has a black face with a long shimmering stripe of pale hairs running from the eye to the mouth. Loxocera sylvatica has yellow shoulders, so is more easily distinguished.

Associated with Juncus species such as Soft-rush and occurring where Juncus species are present.

Summer and autumn.

Larvae feed on Juncus species.

Seems to be widespread and fairly frequent in England and Wales although difficulty of identification makes exact status difficult to determine.

Status in Leicestershire and Rutland not known.
