Xerces: Hylaeus finitimus is a coastal bee endemic to the island of Kauai in Hawaii. It is closely related to H. longiceps of Oahu and Maui Nui. The species is known only from two specimens, one of which is lost, and may be extinct.

Insects of Hawaii: Medium-sized bees with clear wings (only female type available for study). Perkins (1899: 100) described the male H. finitimus only as having the face shaped and colored as in H. longiceps but with the punctation of the scutum and scutellum distinctly finer. In his key (1910:602) H. finitimus has the face shorter and the supraclypeal area about as long as wide compared to H. longiceps, which has the face longer and the apical margin ofthe supraclypeal area much shorter than the sides. Female black and unmarked. No recent collections.

Colors of the integument and pubescence are based on an old specimen. This species was not encountered in collecting at Polihale, an excellent coastal site for Hylaeus on Kauai; however, populations at such an arid site are highly cyclical, and it is possible that even if it occurs there, the three brief collecting trips may have missed it.
