SHORT DESCRIPTION: A small Heriades species (5-6 mm) that resembles our native species H. truncorum (Linnaeus, 1758) . Females can be distinguished by checking the lower margin of clypeus. H. truncorum has two protruding medial tubercles in this area, whereas H. rubicola has a finely crenulate lower margin of the clypeus, with numerous small denticles. Males have short hairs on the first two sternites, whereas males from H. truncorum have long dense hairs.
