One of the traits that separate the Homalictus (a tiny species approximately 3-4 mm) from others such as Eurglossinae (like Hylaeines) is that Homalictus collect pollen on their underside (under their abdomen), whilst Euryglossinae don’t collect pollen externally, they ingest it.

Another trait that aids in the identification of Homalictus is the placement of the antennae. This simple “giveaway” physical traits that separate the families, even if they do look a bit similar… is the location of the antennae sockets, which in the Euryglossinae family, a sub family in the major family Colletidae, is set well below the mid point of the eye. Antennae being “set low”, is defined as being set well below the mid point of the eye.

In this side on view of this native bee, you can see the antennae are set higher up, closer to the mid point of the eye, a trait of the Homalictus, in this example Homalictus dotatus.
