Description

Worker

Worker major. Length 4.5 -5 mm.

Smaller than the typical ramulorum from the Bahamas and differing in coloration. Mandibles and whole head, except the posterior corners, very dark brown, as are also the antennal scapes, except their bases. Thorax also darker brown above than in ramulorum, with the yellow maculae smaller; gaster paler brown, with yellow posterior borders to the segments but appearing much less distinctly fasciate than in the typical form of the species. Tibiae and knees reddish. The coarse punctures on the cheeks and clypeus are much more pronounced than in ramulorum and the occiput has a row of coarse, elongate punctures.

Worker minor. Length about 4 mm.

Also smaller than the worker of the typical ramulorum; head, mesonotum, mesopleurae and dorsal surface of gaster distinctly brown; antennae, knees and tarsi more reddish.

Type Locality Information

Described from five major and two minor workers taken by Dr. Darlington in the northeastern foot-hills of the Massif de la Hotte, Haiti, at an altitude of 3000-4000 ft.
