While it is clearly not one of the long tongued genera (Apis, Amegilla, Megachile, Exoneura) and nor is it Leioproctus, there is not enough detail of the abdominal hair bands or the wing venation to distinguish between Lipotriches and Lasioglossum. The terms long-tongued and short-tongued can be confusing if they are interpreted simply as how far the bee can reach for nectar. The word "tongue" refers to the glossa. In short-tongued bees the glossa is a short disc on the end of a pair of hinged arms that can unfold to send the glossa some distance from the front of the bee. In long-tongued bees, that hinge is very short and is used to slide the tongue up and down in a tube-like proboscis. So the terms are pretty technical.
