Hylaeus in Hawaii

Hylaeus kokeensis

Islands: Kauai

Locations: Kauai - (Awaawapuhi Trail, Kokee Rd.)

Habitats: Montane mesic forest

Plants: Acacia, Chamaesyce

Xerces: No info.

Insects of Hawaii: Small bees with clear to slightly smoky wings. Males with the face entirely yellow (sometimes the margin of the clypeus black), mark extended narrowly above the antennae; usually with marks on pronotal collar and lobes; unusual yellow mark on median plate offorewing (Fig. 3). Lateral process of S8 longer than the width ofthe hemistemite, making it distinctly L-shaped; S8 dilated, without flexure, triangular. Female with long paraocular marks along eye, and a clypeal mark. Most similar to H. mimicus from Oahu and H.filicum from Hawaii; distinguishable from them by the gently arched scape and the median plate.

This species is notable for the yellow mark on the median plate at the base of the forewing; the only other species that has this is H. kona from Hawaii, which has a distinctively shaped scape with a conspicuous groove on the underside. A large series was collected from a single Chamaesyce bush, but it was not encountered elsewhere in the same vicinity, except for a few individuals caught several miles away the previous year on Acacia koa. It probably occurs throughout the mesic zone in the Kokee area.
