Insects of Hawaii: Medium-sized bees with smoky wings and short malar spaces. Male face with oval yellow mark divided by fine black sulci, legs marked with yellow, unusual lateral process of S7 long and broad, sword-shaped, median process of S8 not dilated and with long narrow tips, unusual gonoforceps expanded apically beyond the penis valves. Female black and unmarked, distinguishable from all others by the unique line down the middle of the clypeus. Closely related to H. facilis and H. simplex.

The measured male of H. chlorostictus has extreme ratios of socket diameter/ interantennal distance at 1.9 and antenna-eye distance/interantennal distance at 2.6, indicating that the antennal sockets are extremely close together. The length ratio clypeus/ subantennal sulcus at 2.3 is also unusually high.
