Insects of Hawaii: Small bees with very short malar spaces and clear to slightly smoky wings. Male face with two or three separate marks; process of S8 undilated and with apex simple, gonoforceps subequal to penis valves. Female face with narrow linear yellow stripes at each side along eye margin up to the level of the antennal sockets; pronotum sometimes with large yellow marks on lobes and stripe at each side on collar. The female is similar to H. kauaiensis and H. specularis; it differs from the former in the length ofthe scutum hair and propodeal sculpture, and from the latter in the punctation ofthe frons. Hylaeus mutatus also may have the pronotal lobes marked, which H. kauaiensis never does. The single female H. specularis from Kauai has the lobes unmarked, but females from Hawaii have such marks.
Perkins, in his key (1910:602), placed H. mutatus with species having the scape flat; however, it is distinctly arched.
