Hylaeus in Hawaii


Hylaeus angustulus

Islands: Lanai, Maui

Locations: Maui - (Makawao Forest Reserve)

Habitats: Montane wet forest

Plants: Melicope, Rubus

Xerces: No info.

Insects of Hawaii: Medium-sized bees with clear wings, propodeum with weak basal rugae, otherwise smooth to brow. Male has unusual scape with very slight arch, very short malar space, frons with dull, dense pits but no dark patch of hair, three separate yellow facial marks and otherwise unmarked. Female with black body, short malar space, pronotallobes and collar at extreme sides marked with yellow, sometimes with yellow paraocular marks.

Although this species has not been recollected on Lanai, recent specimens from East Maui match them closely. It is very close to H. dumetorum from Hawaii, including the unique broad groove on the underside of the scape, but lacks the conspicuous patch of long black hair on the frons of that species.
