Wheeler (1905) - This form, which is also common in hollow twigs and Tilliandsias, occurs in various localities in Andros (Dog Key, along the Southern Bight, Big Wood Key, Mangrove Key, Little Golding Key). It approaches the typical form of the species very closely, but may stand as a variety till it is possible to study specimens of the form described by Roger.

Description
All four phases differ from the corresponding forms of var. ramulorum in having much less brown or black on the head and thorax. In some colonies the worker major has the anterior third of the head dark brown, with a large yellow spot on the middle of the clypeus and a large brown blotch on the vertex. In others nearly the whole head is immaculate. The thorax of the worker major commonly has a conspicuous brown blotch on the mesopleurae, and another smaller one on the side of the pronotum. The female has only faint brownish clouds on the head and thorax. The males are yellow, with brown vertex, scutellum, and gaster, the intersegmental constrictions of which are broadly yellow.
