Glidden’s Masked Bee (Hylaeus gliddenae)
This species was described in 2003 based on a single (?) specimen, a male that had been collected sometimes in the early 20th century at an not further specified locality on the Kilauea volcano on the island of Hawai’i.
The species is known to have nested in the burrows left behind by the larvae of beetles from the genus Halcobius in the stems of kolea (Myrsine spp.).
The species differs from nearly all others by its red metasoma (the posterior part of the body), which it shares only with the Paradox Masked Bee (Hylaeus paradoxus (Schrottky)), and by its somewhat u-shaped facial markings. [1]

Obscure Masked Bee (Hylaeus niloticus)
The Obscure Masked Bee is known from the islands of Hawai’i, Lana’i, and Moloka’i, Hawaiian Islands, where it apparently inhabited coastal areas and dry lowland regions.
The species has not been found in recent years and might indeed be extinct. [1]

Maui Masked Bee (Hylaeus mauiensis)
The Maui Masked Bee is known from only two specimens which had been collected in 1899 in the wet mountain rainforests of eastern Maui, Hawaiian Islands, one of these two specimens, a female, is no apparently lost.
The species might well be extinct, however, the locality were the specimens were collected lie within a natural reserve, the mountainous areas of Maui are difficult to access and there have not been any true search efforts, thus this species may sometimes be rediscovered. [1]
